+# Multisig Factory
+
+Allows to create new [Multisig contracts](../multisig) just by sending a transactions with the required configuration and funds.
+E.g. Removes need for using `near repl` and having wasm file available.
+
+# Deployment & Usage
+
+## TestNet
+
+Deploy to new developer account on TestNet:
+
+```
+near dev-deploy --wasmFile=res/multisig_factory.wasm
+```
+
+Setup variable for the contract to use commands below easier:
+
+```
+# bash
+CONTRACT_ID="dev-1608694678554-8567049"
+
+# fish
+set CONTRACT_ID "dev-1608694678554-8567049"
+```
+
+Create a new multisig with the given parameters and attached amount (50N) passed to multisig contract:

+# Multisig contract
+
+*Please do your own due diligence before using this contract. There is no guarantee that this contract doesn't have issues.*
+
+This contract provides:
+ - Set K out of N multi sig scheme
+ - Request to sign transfers, function calls, adding and removing keys.
+ - Any of the access keys or set of specified accounts can confirm, until the required number of confirmation achieved.
+
+## Multisig implementation details
+
+Multisig uses set of `FunctionCall` `AccessKey`s and account ids as a set of allowed N members. 
+When contract is being setup, it should be initialized with set of members that will be initially managing this account.
+All operations going forward will require `K` members to call `confirm` to be executed.
+
+### Initialization
+
+### Request
+
+There are number of different request types that multisig can confirm and execute:
+```rust
+/// Lowest level action that can be performed by the multisig contract.
+pub enum MultiSigRequestAction {
+    /// Transfers given amount to receiver.
+    Transfer {
+        amount: U128,
+    },
+    /// Create a new account.
+    CreateAccount,
+    /// Deploys contract to receiver's account. Can upgrade given contract as well.
+    DeployContract { code: Base64VecU8 },
+    /// Adds new member to multisig, either public key or account.
+    AddMember {
+        member: MultisigMember,
+    },
+    /// Delete existing member from multisig, either public key or account.
+    DeleteMember {
+        member: MultisigMember,
+    },
+    /// Adds key, either new key for multisig or full access key to another account.
+    AddKey {
+        public_key: Base58PublicKey,
+        #[serde(skip_serializing_if = "Option::is_none")]
+        permission: Option<FunctionCallPermission>,
+    },
+    /// Call function on behalf of this contract.
+    FunctionCall {
+        method_name: String,
+        args: Base64VecU8,
+        deposit: U128,
+        gas: U64,
+    },
+    /// Sets number of confirmations required to authorize requests.
+    /// Can not be bundled with any other actions or transactions.
+    SetNumConfirmations {
+        num_confirmations: u32,
+    },
+    /// Sets number of active requests (unconfirmed requests) per access key
+    /// Default is 12 unconfirmed requests at a time
+    /// The REQUEST_COOLDOWN for requests is 15min
+    /// Worst gas attack a malicious keyholder could do is 12 requests every 15min
+    SetActiveRequestsLimit {
+        active_requests_limit: u32,
+    },
+}
+
+/// Permission for an access key, scoped to receiving account and method names with allowance to add when key is added to accoount
+pub struct FunctionCallPermission {
+    allowance: Option<U128>,
+    receiver_id: AccountId,
+    method_names: Vec<String>,
+}
+
+/// The request the user makes specifying the receiving account and actions they want to execute (1 tx)
+pub struct MultiSigRequest {
+    receiver_id: AccountId,
+    actions: Vec<MultiSigRequestAction>,
+}
+
+/// An internal request wrapped with the signer_pk and added timestamp to determine num_requests_pk and prevent against malicious key holder gas attacks
+pub struct MultiSigRequestWithSigner {
+    request: MultiSigRequest,
+    member: MultisigMember,
+    added_timestamp: u64,
+}
+
+/// Represents member of the multsig: either account or access key to given account.
+pub enum MultisigMember {
+    AccessKey { public_key: Base58PublicKey },
+    Account { account_id: AccountId },
+}
+```
+
+### Methods
+
+```rust
+/// Add request for multisig.
+pub fn add_request(&mut self, request: MultiSigRequest) -> RequestId {
+
+/// Add request for multisig and confirm right away with the key that is adding the request.
+pub fn add_request_and_confirm(&mut self, request: MultiSigRequest) -> RequestId {
+
+/// Remove given request and associated confirmations.
+pub fn delete_request(&mut self, request_id: RequestId) {
+
+/// Confirm given request with given signing key.
+/// If with this, there has been enough confirmation, a promise with request will be scheduled.
+pub fn confirm(&mut self, request_id: RequestId) -> PromiseOrValue<bool> {
+```
+
+### View Methods
+```rust
+pub fn get_request(&self, request_id: RequestId) -> MultiSigRequest
+pub fn get_num_requests_per_member(&self, member: MultisigMember) -> u32
+pub fn list_request_ids(&self) -> Vec<RequestId>
+pub fn get_confirmations(&self, request_id: RequestId) -> Vec<MultisigMember>
+pub fn get_num_confirmations(&self) -> u32
+pub fn get_request_nonce(&self) -> u32
+```
+
+### State machine
+
+Per each request, multisig maintains next state machine:
+ - `add_request` adds new request with empty list of confirmations.
+ - `add_request_and_confirm` adds new request with 1 confirmation from the adding key.
+ - `delete_request` deletes request and ends state machine.
+ - `confirm` either adds new confirmation to list of confirmations or if there is more than `num_confirmations` confirmations with given call - switches to execution of request. `confirm` fails if request is already has been confirmed and already is executing which is determined if `confirmations` contain given `request_id`.
+ - each step of execution, schedules a promise of given set of actions on `receiver_id` and puts a callback.
+ - when callback executes, it checks if promise executed successfully: if no - stops executing the request and return failure. If yes - execute next transaction in the request if present.
+ - when all transactions are executed, remove request from `requests` and with that finish the execution of the request.   
+ 
+## Pre-requisites
+
+To develop Rust contracts you would need to:
+* Install [Rustup](https://rustup.rs/):
+```bash
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+```
+* Add wasm target to your toolchain:
+```bash
+rustup target add wasm32-unknown-unknown
+```
+
+## Building the contract
+
+```bash
+./build.sh
+```
+
+## Usage
+
+Before deploying the contract, you need to collect all public keys that it will be initialized with.
+
+Commands to deploy and initialize a 2 out of 3 multisig contract via `near repl`:
+
+```javascript
+const fs = require('fs');
+const account = await near.account("illia");
+const contractName = "multisig.illia";
+const methodNames = ["add_request","delete_request","confirm"];
+const newArgs = {"num_confirmations": 2, "members": [
+        { "public_key": "ed25519:Eg2jtsiMrprn7zgKKUk79qM1hWhANsFyE6JSX4txLEuy" },
+        { "public_key": "ed25519:HghiythFFPjVXwc9BLNi8uqFmfQc1DWFrJQ4nE6ANo7R" },
+        { "public_key": "ed25519:2EfbwnQHPBWQKbNczLiVznFghh9qs716QT71zN6L1D95" },
+        { "account_id": "illia" },
+    ]};
+const result = account.signAndSendTransaction(
+    contractName,
+    [
+        nearAPI.transactions.createAccount(),
+        nearAPI.transactions.transfer("100000000000000000000000000"),
+        nearAPI.transactions.deployContract(fs.readFileSync("res/multisig.wasm")),
+        nearAPI.transactions.functionCall("new", Buffer.from(JSON.stringify(newArgs)), 10000000000000, "0"),
+    ]);
+```
+
+### Create request
+
+To create request for transfer funds:
+```bash
+near call multisig.illia add_request '{"request": {"receiver_id": "illia", "actions": [{"type": "Transfer", "amount": "1000000000000000000000"}]}}' --accountId multisig.illia
+```
+
+Add another key to multisig:
+```bash
+near call multisig.illia add_request '{"request": {"receiver_id": "multisig.illia", "actions": [{"type": "AddMember", "member": {"public_key": "ed25519:<base58 of the key>"}}]}}' --accountId multisig.illia
+```
+
+Change number of confirmations required to approve multisig:
+```bash
+near call multisig.illia add_request '{"request": {"receiver_id": "multisig.illia", "actions": [{"type": "SetNumConfirmations", "num_confirmations": 2}]}}' --accountId multisig.illia
+```
+
+Returns the `request_id` of this request that can be used to confirm or see details.
+
+As a side note, for this to work one of the keys from multisig should be available in your `~/.near-credentials/<network>/<multisig-name>.json` or use `--useLedgerKey` to sign with Ledger.
+
+You can also create a way more complex call that chains calling multiple different contracts:
+
+### Confirm request
+
+To confirm a specific request:
+```bash
+near call multisig.illia confirm '{"request_id": 0}' --accountId multisig.illia
+```
+
+### View requests
+
+To list all requests ids:
+```bash
+near view multisig.illia list_request_ids
+```
+
+To see information about specific request:
+```bash
+near view multisig.illia get_request '{"request_id": 0}'
+```
+
+To see confirmations for specific request:
+```bash
+near view multisig.illia get_confirmations '{"request_id": 0}'
+```
+
+Total confirmations required for any request:
+```
+near view multisig.illia get_num_confirmations
+```
+
+### Upgrade given multisig with new code
+
+Create a request that deploys new contract code on the given account.
+Be careful about data and requiring migrations (contract updates should include data migrations going forward). 
+
+```javascript
+const fs = require('fs');
+const account = await near.account("multisig.illia");
+const contractName = "multisig.illia";
+const requestArgs = {"request": [
+    {"receiver_id": "multisig.illia", "actions": [{"type": "DeployContract", "code": fs.readFileSync("res/multisig.wasm")}]}
+]};
+const result = account.signAndSendTransaction(
+    contractName,
+    [
+        nearAPI.transactions.functionCall("add_request", Buffer.from(JSON.stringify(requestArgs)), 10000000000000, "0"),
+    ]);
+```
+
+After this, still will need to confirm this with `num_confirmations` you have setup for given contract.
+
+### Common commands for multisig
+
+__Create an account__
+
+```
+near call illia.near add_request '{"request": {"receiver_id": "new_account.near", "actions": [{"type", "CreateAccount"}, {"type": "Transfer", "amount": "1000000000000000000000"}, {"type": "AddKey", "public_key": "<public key for the new account>"}]}}' --accountId illia.near
+near call illia.near confirm '{"request_id": <request number from previous line>}'
+```
+
+## Deploying and building
+
+This repository has simulation tests, which can offer more advanced testing functionality than unit tests. However, this means the manifest (`Cargo.toml`) should be modified to reduce the contract size when building for production.
+
+Remove the `rlib` like shown here:
+
+```diff
+[lib]
+# Below is used for production
++crate-type = ["cdylib"]
+# Below used when running simulation tests
++# crate-type = ["cdylib", "rlib"]
+```
