The middleware is a caching and reporting layer which sits in front of the nodes of the æternity blockchain. Its purpose is to respond to queries faster than the node can do, and to support queries that for reasons of efficiency the node cannot or will not support itself.
The architecture of the app is explained here.
Firstly, clone the middleware repo:
git clone https://github.com/aeternity/ae_mdw && cd ae_mdw
Before running it, it's recommended to use a Node database snapshot for faster syncing.
- Download one of the full backups from https://downloads.aeternity.io
- Create a 'data' directory under the root repo dir and extract the backup to it (it creates a mnesia directory).
To start a docker container on mainnet, simply run: docker-compose up.
You can check on /status page that the node_height is higher than 600000.
In case you want to use it on testnet or for development purposes please follow the instructions below.
The middleware runs along with an Aeternity Node on the same docker container and BEAM VM instance.
Its configuration file is found at docker/aeternity.yaml. Under fork_management key, the network_id options are: ae_mainnet and ae_uat (testnet).
If you are running your own build, on dev environment, with docker-compose-dev.yml the docker/aeternity.yaml is copied when the container is started and it is used as a node configuration file.
For docker hub images, you can create a volume to copy your local /home/aeternity/aeternity.yaml by uncommenting it on docker-compose.yml.
You may also redefine other Aeternity node configurations. More information regarding configuration can be found here
The aeternity/ae_mdw docker image runs with unprivileged user (uid=1000).
Therefore permissions should be given when mapping the data/mnesia and/or data/mdw.db volumes:
mkdir -p data/mnesia data/mdw.db
chown -R 1000 data
In case you want to setup different accounts on testnet with initial balance you can add this volume to docker-compose-dev.yml:
- ${PWD}/accounts_test.json:/home/aeternity/node/local/rel/aeternity/data/aecore/.genesis/accounts_test.json
An example of accounts_test.json is:
{
"ak_2a1j2Mk9YSmC1gioUq4PWRm3bsv887MbuRVwyv4KaUGoR1eiKi": 10000000000000000000000000000000
}
The project comes with a two docker compose files:
docker-compose.yml: to run the middleware as isdocker-compose-dev.yml: for development env that includes dev tools
A helper script might be used to get a docker shell on dev env: ./scripts/do.sh docker-shell
You should now be able to navigate through the project having the /app as working directory.
When inside the docker container shell, some useful commands that you might want to run are:
iex --sname aeternity@localhost -S mix # IEx shell
elixir --sname aeternity@localhost -S mix phx.server # Start the server
elixir --sname aeternity@localhost -S mix test # Unit tests
INTEGRATION_TEST=1 elixir --sname aeternity@localhost -S mix test.integration # Integration tests
mix format # Run formatting tool
mix credo # Run `credo` tool
mix dialyzer # Run `dialyzer` tool
We currently provide hosted infrastructure at https://mainnet.aeternity.io/mdw/ , all examples here are based on it.

The swagger specification of the endpoints can be downloaded from:
It can be visualized on a swagger UI at:
This npm package can be also used for a self-hosted app to visualize these specs: https://www.npmjs.com/package/swagger-ui
The application does not support paginated page-based endpoints. Instead, a
cursor-based pagination is offered. This means that in order to traverse through
a list of pages for any of the paginated endpoints, either the next or prev
field from the current page has to be used instead.
Asking for an arbitrary page, without first retrieving it from the next or
prev field is not supported.
The paginated endpoints return JSON in the following format:
{
"data": [...objects...],
"next": continuation-URL or null,
"prev": continuation-URL or null
}
The continuation-URL, when concatenated with host, has to be used to
retrieve a new page of results.

Once there are no more transactions for a query, the next key is set to null.
The client can set limit explicitly if he wishes to receive different number
of transactions in the reply than 10 (max 100).
The scope parameter specifies the time period to look for transactions matching the criteria:
gen:A-B- from generation A to B (forward if A < B, backward otherwise)txi:A-B- from transaction index A to B (forward if A < B, backward otherwise)
Not all paginated endpoints support all scopes.
All paginated endpoints support a direction parameter that specifies the order in which results are expected to be returned.
It can be either forward or backward (default).
In many of the endpoints there's some additional query parameters that can be sent to change the endpoint behavior.
When expand=true is sent on the URL, it displays additional information.
Most oracle and name endpoints allow this option.
When top=true, it displays the latest state of the changes by querying the node directly. This is allowed on some of the AEx9 endpoints to obtain the latest balances state for a given contract.
Currently, in the endpoints created from the beginning, transactions were identified by a "transaction index". Since recently, we've decided this shouldn't really be the case: transactions are to be identified exclusively via the transaction hash. This is because forks caused different transactions to have the same (consecutive and sequentially calculated) transaction indexes.
For the new endpoints, though, we highly recommend not to use transaction indexes, instead, use tx_hash=true for all endpoints and use exclusively the transaction hashes.
In the newer versions of the API, the transaction index will stop being exposed, regardless of the tx_hashquery parameter.
Querying for transactions via /v2/txs endpoint supports 3 kinds of parameters specifying which transactions should be part of the reply:
- types
- generic ids
- transaction fields
Types of transactions in the resulting set can be constrained by providing type and/or type_group parameter.
The query allows providing of multiple type & type_group parameters - they form a union of admissible types.
(In other words - they are combined with OR.)
Supported types:
channel_close_mutual,channel_close_solo,channel_create,channel_deposit,channel_force_progress,channel_offchain,channel_settle,channel_slash,channel_snapshot_solo,channel_withdraw.contract_call,contract_createga_attach,ga_metaname_claim,name_preclaim,name_revoke,name_transfer,name_updateoracle_extend,oracle_query,oracle_register,oracle_responsepaying_forspend
Supported type groups:
- channel
- contract
- ga
- name
- oracle
- paying
- spend

Generic ids allow selecting of transactions related to the provided id in any way.
With generic ids, it is possible to select also create/register transactions of particular AEternity object (like contract, channel or oracle), despite the fact that these transactions don't have the ID of the created object among its transaction fields.
Supported generic IDs:
accountcontractchanneloracle
(todo: name)

Every transaction record has one or more fields with identifier, represented by public key. Middleware is indexing these fields and allows them to be used in the query.
Supported fields with provided transaction type:
The syntax of the field with provided type is: type.field - for example: spend.sender_id
The fields for transaction types are:
- channel_close_mutual - channel_id, from_id
- channel_close_solo - channel_id, from_id
- channel_create - initiator_id, responder_id
- channel_deposit - channel_id, from_id
- channel_force_progress - channel_id, from_id
- channel_offchain - channel_id
- channel_settle - channel_id, from_id
- channel_slash - channel_id, from_id
- channel_snapshot_solo - channel_id, from_id
- channel_withdraw - channel_id, to_id
- contract_call - caller_id, contract_id
- contract_create - owner_id, contract_id
- ga_attach - owner_id, contract_id
- ga_meta - ga_id
- name_claim - account_id
- name_preclaim - account_id, commitment_id
- name_revoke - account_id, name_id
- name_transfer - account_id, name_id, recipient_id
- name_update - account_id, name_id
- oracle_extend - oracle_id
- oracle_query - oracle_id, sender_id
- oracle_register - account_id
- oracle_response - oracle_id
- paying_for - payer_id
- spend - recipient_id, sender_id
Supported freestanding fields:
In case a freestanding field (without transaction type) is part of the query, it deduces the admissible set of types to those which have this field.
The types for freestanding fields are:
- account_id - name_claim, name_preclaim, name_revoke, name_transfer, name_update, oracle_register
- caller_id - contract_call
- channel_id - channel_close_mutual, channel_close_solo, channel_deposit, channel_force_progress, channel_offchain, channel_settle, channel_slash, channel_snapshot_solo, channel_withdraw
- commitment_id - name_preclaim
- contract_id - contract_call
- entrypoint - contract_call
- from_id - channel_close_mutual, channel_close_solo, channel_deposit, channel_force_progress, channel_settle, channel_slash, channel_snapshot_solo
- ga_id - ga_meta
- initiator_id - channel_create
- name_id - name_revoke, name_transfer, name_update
- oracle_id - oracle_extend, oracle_query, oracle_response
- owner_id - contract_create, ga_attach
- payer_id - paying_for
- recipient_id - name_transfer, spend
- responder_id - channel_create
- sender_id - oracle_query, spend
- to_id - channel_withdraw
Supported inner transactions fields:
The ga_meta and paying_for transactions have inner transactions which might be filtered as if they were not inner.
For example, for a GAMetaTx with inner SpendTx, one might request with the following query params:
- spend.recipient_id or
- spend.sender_id or
- spend.recipient_id and spend.sender_id

The query string can mix types, global ids and transaction fields.
The resulting set of transactions must meet all constraints specified by parameters denoting ID (global ids and transaction fields) - the parameters are combined with AND.
If type or type_group is provided, the transaction in the result set must be of some type specified by these parameters.
transactions where each transaction contains both accounts, no matter in which field:

There are several endpoints for querying block(s) or generation(s). A generation can be understood as key block and micro blocks containing transactions.
Since we are returning whole generations, replies can be very large.
Examples below are trimmed heavily.

There are several endpoints for querying of the Naming System.
Name objects in Aeternity blockchain have a lifecycle formed by several types of transactions. Names can become claimed (directly or via name auction), updated the lifespan or pointers, transferred the ownership and revoked when not needed.
Information about the name returned from the name endpoints summarizes this lifecycle in vectors of transaction indices, under keys claims, updates, transfers and optional transaction index in revoke.
Transaction index is useful for retrieving detailed information about the transaction via txi/:index endpoint.
Using txi/:index endpoint is flexible, on-demand way to get detailed transaction information, but in some situations leads to multiple round trips to the server.
Due to this reason, all name endpoints except name/pointers and name/pointees support expand parameter (either set to true or without value), which will replace the transaction indices with the JSON body of the transaction detail.
Names can be filtered by state, which can contain the following values:
inactive- for listinginactivenames (expired or revoked)active- for listingactivenamesauction- for listingauctions
They support ordering via parameters by (with value activation, deactivation or name), and direction (with value forward or backward).
Using the by=activation requires state=active and includes only successfully claimed names (those in auction won't appear yet).
Using the by=deactivation means for inactive names that they are sorted by the height of deactivation, whether the name had expired or had been revoked.
For active names it means they are sorted by expiration height.
Without these parameters, the endpoints return results ordered as if by=deactivation and direction=backward were provided.
The parameter limit (by default = 10) is optional, and limits the number of elements in the response.

The attributes returned on each object are the following:
-
args- a list of event constructor arguments as big integers. Contract bytecode doesn't contain metadata describing the types of the contract events. As a result, we can only report the binary blobs to the user, which can be either an integer (probably denoting an amount or counter), or public key. The integer can be converted to public key (256-bits) binary in Elixir (or Erlang) shell:iex(aeternity@localhost)3> <<32049452134983951870486158652299990269658301415986031571975774292043131948665 :: 256>> <<70, 219, 88, 217, 218, 57, 227, 219, 63, 200, 168, 207, 16, 238, 173, 185, 185, 214, 3, 207, 227, 124, 221, 54, 36, 147, 13, 144, 171, 6, 142, 121>> -
call_tx_hash- hash of contract call transaction which emitted the event log -
call_txi- tx index of contract call transaction -
contract_id- contract identifier -
contract_txi- tx index of contract create transaction -
data- decoded (human readable) data field of event log (if any) -
event_hash- base32hex encoded blake2b hash of the name of the event constructor The source of the contract in question has one of the event log constructors named "TipReceived". Its encoded hash can be retrieved as:iex(aeternity@localhost)11> Base.hex_encode32(:aec_hash.blake2b_256_hash("TipReceived")) "MVGUQ861EKRNBCGUC35711P9M2HSVQHG5N39CE5CCIUQ7AGK7UU0====" -
ext_caller_contract_id- caller contract id, potentially different tocontract_id, if the contract which emitted the event was called from other contract -
ext_caller_contract_txi- tx index of caller's contract create transaction -
log_idx- contract call can emit many events. Log idx uniquely identifies the event log inside the contract call.
From the above, it is obvious that due to the lack of useful metadata in the contract bytecode, browsing contract logs isn't user friendly.
However, logs are still useful for people writing the contracts since they have source code of the contract.
With access to the contract's source code, the developer can:
- identify the event log constructor from the
event_hashfield - with the constructor, the developer knows the types of
argsfor a particular event log - integer arguments are then understandable literally, while hashes need one more step:
-
after extracting the binary of the argument, this binary should be then passed to:
:aeser_api_encoder.encode(<id-type>, extracted-binary)where the
<id-type>can be one of::account_pubkey,:contract_pubkey,:oracle_pubkeyand others, the full list of known types is here (in Erlang syntax):https://github.com/aeternity/aeserialization/blob/master/src/aeser_api_encoder.erl#L16

During the operation of the node, several kinds of internal transfers happen which are not visible on general transaction ledger.
Besides specifying of scope and direction as with other streaming endpoints (via forward/backward or gen), the query accepts following filters:
-
kind. At the moment, following kinds of transfers can be queried:-
fee_spend_name(fee for placing bid to the name auction) -
fee_refund_name(returned fee when the new name bid outbids the previous one in the name auction)fee_lock_name(locked fee of the name auction winning)reward_oracle(reward for the operator of the oracle (on transaction basis))
-
reward_block(reward for the miner (on block basis)) -
reward_dev(reward for funding of the development (on block basis)) -
accounts_minerva,accounts_fortunaandaccounts_lima(added on hardforks including migrated ERC20 amounts)It it possible to provide just a prefix of the kind in interest, e.g.: "reward" will return all rewards, "fee" will return all fees, "accounts" will return credits after hardforks.
-
-
account- account which received rewards or that was charged fees or that received tokens after a hardfork migration.

There are several endpoints for fetching information about the oracles.
Oracles in Aeternity blockchain have a lifecycle formed by several types of transactions, similar to the Name objects.
For the same reason as Names, all oracle endpoints support expand parameter (either set to true or without value), which will replace the transaction indices with the JSON body of the transaction detail.

Returns active channels ordered by the txi of the last update.
These can also be filtered by state=active or state=inactive.
Besides the participants balances it includes some fields intrinsic to the channel such as:
- the reserve deposited in the channel for paying fees and assuring refunds;
- lock parameters, in case of individual actions; and
- delegates allowed to represent participants

Returns the state of an active/inactive channel.
Optionally a block_hash parameter might be used to query for the state on a specific block.
In this example it retrieves the ChannelDepositTx as the last udpate for a block prior to the last update that was a ChannelCloseMutualTx.

There are 2 endpoints for listing tokens as defined by AEX9 (https://github.com/aeternity/AEXs/blob/master/AEXS/aex-9.md)
/aex9/by_name- for listing tokens sorted by name/aex9/by_symbol- for listing tokens sorted by symbol
These endpoints optional parameters:
all- for listing all contract creations for a token, not just the last one (default: false)prefixORexact- for listing tokens with the name or symbol, which are matching either by prefix, or exactly

There are 3 endpoints for listing token balance of the contract for given account:
-
/aex9/balance/:contract_id/:account_id- shows account balance at the current top of the chain -
/aex9/balance/hash/:blockhash/:contract_id/:account_id- shows account balance at given block -
/aex9/balance/gen/:range/:contract_id/:account_id- show account balances at given height or range of heights
Additional 3 endpoints can be used for showing ALL balances for a given contract:
-
/aex9/balances/:contract_id- shows all balances at the current top of the chain -
/aex9/balances/hash/:blockhash/:contract_id- shows all balances at given block -
/aex9/balances/gen/:range/:contract_id- shows all balances at given height or range of heights
Lastly, 3 endpoints can show balances over all contracts for a given account:
/aex9/balances/gen/:height/account/:account_id- shows balances of all contracts at height for account/aex9/balances/hash/:blockhash/account/:account_id- shows balances of all contracts at blockhash for account/aex9/balances/account/:account_id- shows token balances of all contracts for given account at the current top of the chain
Endpoints which use the current top of the chain:
/aex9/balance/:contract_id/:account_id/aex9/balances/:contract_id/aex9/balances/account/:account_id
use the latest key block as a source of information for returning of the balances.
If the user wishes, she can provide a query parameter top to the query.
Its presence or binding it to true will use the latest micro block for retrieving balances of the contract(s).

The top parameter at this endpoint, when present, can show the most up to date balance as a result of contract call, but can't show an account balance of freshly created AEX9 contract.
The awareness that the contract is created by some account comes from syncing, which is inherently one generation behind the top of the chain.

AEX-141 NFT contracts might organize the access and storage of NFTs metadata in flexible ways. This behaviour is declared during contract creation with the metadata_type field. This and other meta_info fields like name and symbol can be accessed by /aex141 endpoint that displays information about NFT contracts.
With other endpoints it's possible to know more about AEX-141 NFTs including:
- who is the owner of an NFT
- who are the nft owners on a collection
- which NFTs a wallet owns
- NFT transfers filtered by contract and/or wallet
- and more to come ...
Returns creation and stats information in default paginated way for all NFT collection.

Intended for being able to display all events in which a specific account is related to in any way.
An activity event occurs when there's any change in the blockchain related to a specific account. It is not the same as the log events which occur when executing a contract.
Paginated list of events related to the :id account.
Each activity contains 3 values:
height- The height in which the event occurredtype- The type of event.payload- An object whose structure depends on the type of event.
For transaction events the activity type will be <TxType>Event, and the payload will contain a single transaction object as displayed in the /v2/txs endpoint.
Transaction events can also be InternalContractCallEvent which represent transactions that happen internally during a contract call.
Optionally the owned_only=true parameter might be used to return only activities initiated by the account.
Additionally, activities can be filtered by any of these types using ?type=<type> query parameter:
transactions- Transactions containing the account in any of the transaction fieldsaexn- AExN (aex9 and aex141) activitiesaex9- AEx9 activitiesaex141- AEx141 activitiescontract- Internal and external contract callstransfers- Internal (both gen-based and tx-based) transfersclaims- Name claims related to the name hash

The websocket interface, which listens by default on port 4001, gives asynchronous notifications when various events occur.
Each event is notified twice: firstly when the Node has synced the block or transaction and after when AeMdw indexation is done.
In order to differentiate, please check the "source" field on Publishing Message format.

- Subscribe
- Unsubscribe
- KeyBlocks
- MicroBlocks
- Transactions
- Object, which takes a further field,
target- can be any æternity entity. So you may subscribe to any æternity object type, and be sent all transactions which reference the object. For instance, if you have an oracleok_JcUaMCu9FzTwonCZkFE5BXsgxueagub9fVzywuQRDiCogTzseyou may subscribe to this object and be notified of any events which relate to it - presumable you would be interested in queries, to which you would respond. Of course you can also subscribe to accounts, contracts, names, whatever you like.
The V1 websocket interface accepts JSON - encoded commands to subscribe and unsubscribe, and answers these with the list of subscriptions. A session will look like this:

Actual chain data is wrapped in a JSON structure identifying the subscription to which it relates.
{
"payload": "<sync info payload>",
"source": "node" | "mdw",
"subscription": "KeyBlocks" | "MicroBlocks" | "Transactions" | "Object"
}
When the source is "node" it means that the Node is synching the block or transaction (not yet indexed by AeMdw).
If it's "mdw", it indicates that it's already available through AeMdw Api.
The V2 websocket interface behaves the same way as the V1 interface, but when the published message has source mdw it returns the rendered representation of the object as it would be rendered by the middleware (e.g. the returned object for the Transactions subscription will be the same object as returned by the /v2/txs endpoint).
Running unit tests will not sync the database. To run them:
elixir --sname aeternity@localhost -S mix test
The database has to be fully synced. Then, run the tests with:
elixir --sname aeternity@localhost -S mix test.integration
These tests allow you to create your own transactions using the devmode (plus the JS SDK). To add newer tests you need to:
- Add the transactions creation on
node_sdk/index.js. - Run the JavaScript file using
docker-compose -f docker-compose-dev.yml run node_sdk node index.js. - Add new devmode tests under the
test/devmode/directory. - Run tests using
./scripts/test-devmode.sh.

In order to anticipate some of these checks one might run mix git_hooks.install.
This installs pre_commit and pre_push checks as defined by config :git_hooks in dev.tools.exs.
If sure about the change, if it was for example in an integration test case and it was already tested and formatted,
one can use git push --no-verify to bypass the hook.
Every time an endpoint is changed, the swagger v2 file should be changed as well.
