Methods
Load the private keys of the authority public keys in order to approve transactions with them
const account = await eoslime.Account.createRandom();const keys = [await eoslime.utils.generateKeys(),await eoslime.utils.generateKeys()]await account.addOnBehalfKey(keys[0].publicKey)await account.addOnBehalfKey(keys[1].publicKey)await account.increaseThreshold(2);const multiSigAccount = eoslime.MultiSigAccount.load(account.name, account.privateKey);multiSigAccount.loadKeys(keys.map((key) => { return key.privateKey }));
Load the accounts configured to act on behalf of the multisignature authority
const account = await eoslime.Account.createRandom();const accounts = await eoslime.Account.createRandoms(2);await account.addOnBehalfAccount(accounts[0].name);await account.addOnBehalfAccount(accounts[1].name);await account.increaseThreshold(3);const multiSigAccount = eoslime.MultiSigAccount.load(account.name, account.privateKey);multiSigAccount.loadAccounts(accounts);
Propose a transaction to be executed
Parameters
contractAction - Instance of ContractFunction. ContractFunctions are all contract methods constructed with eoslime
const faucetContract = eoslime.Contract.fromFile(FAUCET_ABI_PATH, faucetAccount.name, faucetAccount);// produce is a ContractFunction constructed from the contract ABIawait faucetContract.actions.produceactionData - An array of the parameters you will want the produce function to be called with
You are loading actually the proposer account with
MultiSigAccount.load
When you are proposing a transaction, behind the scene the proposer approves it.
const proposer = await eoslime.Account.createRandom();const onBehalfAccounts = await eoslime.Account.createRandoms(2);await proposer.addOnBehalfAccount(onBehalfAccounts[0].name);await proposer.addOnBehalfAccount(onBehalfAccounts[1].name);await proposer.increaseThreshold(2);const multiSigAccount = eoslime.MultiSigAccount.load(proposer.name, proposer.privateKey);multiSigAccount.loadAccounts(onBehalfAccounts);const proposalId = await multiSigAccount.propose(faucetContract.actions.produce, [account.name, "100.0000 TKNS", account.name, "memo"]);
Sign a proposed transaction
Parameters
publicKey - publicKey of a loaded account/key
const faucetContract = eoslime.Contract.fromFile(FAUCET_ABI_PATH, faucetAccount.name, faucetAccount);// produce is a ContractFunction constructed from the contract ABIawait faucetContract.actions.produceproposalId - Response of the propose method
const proposer = await eoslime.Account.createRandom();const onBehalfAccounts = await eoslime.Account.createRandoms(2);await proposer.addOnBehalfAccount(onBehalfAccounts[0].name);await proposer.addOnBehalfAccount(onBehalfAccounts[1].name);await proposer.increaseThreshold(2);const multiSigAccount = eoslime.MultiSigAccount.load(proposer.name, proposer.privateKey);multiSigAccount.loadAccounts(onBehalfAccounts);const proposalId = await multiSigAccount.propose(faucetContract.actions.produce, [account.name, "100.0000 TKNS", account.name, "memo"]);await multiSigAccount.approve(multiSigAccount.accounts[0].publicKey, proposalId);
Broadcast proposal in case of enough approvals
const proposer = await eoslime.Account.createRandom();const onBehalfAccounts = await eoslime.Account.createRandoms(2);await proposer.addOnBehalfAccount(onBehalfAccounts[0].name);await proposer.addOnBehalfAccount(onBehalfAccounts[1].name);await proposer.increaseThreshold(2);const multiSigAccount = eoslime.MultiSigAccount.load(proposer.name, proposer.privateKey);multiSigAccount.loadAccounts(onBehalfAccounts);const proposalId = await multiSigAccount.propose(faucetContract.actions.produce, [account.name, "100.0000 TKNS", account.name, "memo"]);await multiSigAccount.approve(multiSigAccount.accounts[0].publicKey, proposalId);/*By doing propose, the proposer approves the transactionIn order the transaction to be executed it requires 2 signaturesbecause of the treshold. That is why we need only one approve*/const txReceipt = await multiSigAccount.processProposal(proposalId);
