WoopChain's go-sdk

This is a go layer on top of the WoopChain RPC, included is a CLI tool that you can build with a simple invocation of make

See https://docs.wikiwoop.com/home/network/wallets/woop-cli/download-setup for detailed documentation on how to use the wiki CLI tools

Build

Working directly on this repo can be challenging because of the upstream dependencies. Follow the README in the main repo for an already ready development environment: https://github.com/woop-chain/woop/blob/main/README.md.

...for the impatient:

$ docker run -it  woopchain/main:stable /bin/bash
$ cd ../go-sdk
$ git pull -r origin main
$ make

Usage & Examples

wiki implements a fluent API, that is, there is a hierarchy of commands.

bash completions

once built, add wiki to your path and add to your .bashrc

. <(wiki completion)

invoke the following command to see the most command usages of wiki

$ wiki cookbook

Cookbook of Usage

Note:

1) Every subcommand recognizes a '--help' flag
2) If a passphrase is used by a subcommand, one can enter their own passphrase interactively
   with the --passphrase option. Alternatively, one can pass their own passphrase via a file
   using the --passphrase-file option. If no passphrase option is selected, the default
   passphrase of '' is used.
3) These examples use Shard 0 of Mainnet as argument for --node

Examples:

1.  Check account balance on given chain
./wiki --node=https://rpc.woopchain.com balances <SOME_WOC_ADDRESS>

2.  Check sent transaction
./wiki --node=https://rpc.woopchain.com blockchain transaction-by-hash <SOME_TX_HASH>

3.  List local account keys
./wiki keys list

4.  Sending a transaction (waits 40 seconds for transaction confirmation)
./wiki --node=https://rpc.woopchain.com transfer \
    --from <SOME_WOC_ADDRESS> --to <SOME_WOC_ADDRESS> \
    --from-shard 0 --to-shard 1 --amount 200 --passphrase

5.  Sending a batch of transactions as dictated from a file (the `--dry-run` options still apply)
./wiki --node=https://rpc.woopchain.com transfer --file <PATH_TO_JSON_FILE>
Check README for details on json file format.

6.  Check a completed transaction receipt
./wiki --node=https://rpc.woopchain.com blockchain transaction-receipt <SOME_TX_HASH>

7.  Import an account using the mnemonic. Prompts the user to give the mnemonic.
./wiki keys recover-from-mnemonic <ACCOUNT_NAME>

8.  Import an existing keystore file
./wiki keys import-ks <PATH_TO_KEYSTORE_JSON>

9.  Import a keystore file using a secp256k1 private key
./wiki keys import-private-key <secp256k1_PRIVATE_KEY>

10. Export a keystore file's secp256k1 private key
./wiki keys export-private-key <ACCOUNT_ADDRESS> --passphrase

11. Generate a BLS key then encrypt and save the private key to the specified location.
./wiki keys generate-bls-key --bls-file-path <PATH_FOR_BLS_KEY_FILE>

12. Create a new validator with a list of BLS keys
./wiki --node=https://rpc.woopchain.com staking create-validator --amount 10 --validator-addr <SOME_WOC_ADDRESS> \

PS: key must first use (wiki keys import-private-key) to import

22. Enter Console
./wiki command --net=testnet

Sending batched transactions

One may find it useful to send a batch of transaction with 1 instance of the binary. To do this, one can specify a JSON file with the transaction subcommand to dictate a batch of transaction to send off in sequential order.

Example:

wiki --node="rpc1.woopchain.com/" transfer --file ./batchTransactions.json

Note that the --wait-for-confirm and --dry-run options still apply when sending batched transactions

Transfer JSON file format

The JSON file will be a JSON array where each element has the following attributes:

Key	Value-type	Value-description
from	string	[Required] Sender's one address, must have key in keystore.
to	string	[Required] The receivers woc address.
amount	string	[Required] The amount to send in $WOC.
from-shard	string	[Required] The source shard.
to-shard	string	[Required] The destination shard.
passphrase-file	string	[Optional] The file path to file containing the passphrase in plain text. If none is provided, check for passphrase string.
passphrase-string	string	[Optional] The passphrase as a string in plain text. If none is provided, passphrase is ''.
nonce	string	[Optional] The nonce of a specific transaction, default uses nonce from blockchain.
gas-price	string	[Optional] The gas price to pay in NANO (1e-9 of $WOC), default is 1.
gas-limit	string	[Optional] The gas limit, default is 21000.
stop-on-error	boolean	[Optional] If true, stop sending transactions if an error occurred, default is false.
true-nonce	boolean	[Optional] If true, send transaction using true on-chain nonce. Cannot be used with nonce. If none is provided, use tx pool nonce.

Batched transaction response format

The return will be a JSON array where each element is a transaction log. The transaction log has the following attributes:

Key	Value-type	Value-description
transaction-receipt	string	The transaction hash/receipt if the CLI signed and sent a transaction, otherwise this key will not exist
transaction	JSON Object	The transaction parameters if --dry-run is toggled, otherwise this key will not exist.
blockchain-receipt	JSON Object	The transaction receipt from the blockchain if wait-for-confirm is > 0, otherwise this key will not exist.
raw-transaction	string	The raw bytes in hex of a sighed transaction if --dry-run is toggled, otherwise this key will not exist
errors	JSON Array	A JSON array of strings describing any error that occurred during the execution of a transaction. If no errors, this key will not exist.
time-signed-utc	string	The time in UTC as a string of roughly when the transaction was signed. If no signed transaction, this key will not exist.

Example of returned JSON Array:

Offline sign transfer

1. Get Nonce From a Account. (Need to be online, but no passphrase required)

./wiki get-nonce --node=https://rpc.woopchain.com --from=[WOC address]

2. Sign transfer and write to file. (Passphrase required, But no need to be online)

./wiki transfer --offline-sign --nonce=[nonce value from previous] --from=[WOC address] --to=[WOC address] --amount=1000 --from-shard=0 --to-shard=0 > signed.json

3. send signed.json to Woop blockchain! (Need to be online, but no passphrase required)

./wiki offline-sign-transfer --node=https://trpc.woopchain.com --file ./signed.json

Debugging

The go-sdk code respects WIKI_RPC_DEBUG WIKI_TX_DEBUG as debugging based environment variables.

WIKI_RPC_DEBUG=true WIKI_TX_DEBUG=true ./wiki blockchain protocol-version

Contract Deploy

You can deploy the contract use the command;

./wiki command --node="https://trpc.woopchain.com" --net=testnet

Then you can test this code to deploy a smart contract

var abi = [{"constant":false,"inputs":[],"name":"changeIt","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"number","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"}]
var code = '0x60806040526212345660005534801561001757600080fd5b5060c8806100266000396000f3006080604052600436106049576000357c0100000000000000000000000000000000000000000000000000000000900463ffffffff16806327b5c17514604e5780638381f58a146062575b600080fd5b348015605957600080fd5b506060608a565b005b348015606d57600080fd5b5060746096565b6040518082815260200191505060405180910390f35b62654321600081905550565b600054815600a165627a7a72305820294db9eed647c48762212fd43bf9ed7733c9d9f43b1ce5583bb4c2bae97fae770029'
var account = 'woc1xjanr7lgulc0fqyc8dmfp6jfwuje2d94xfnzyd' // change this to your account address, support eth or woc address
var myContract=eth.contract(abi)
contract = myContract.new({from:account,data:code})

Wait for a few seconds and it's ready to use
