Deploy a multisig contract

The sdk contains components to interact with the Multisig Contract. We can deploy a multisig smart contract, add members, propose and execute actions and query the contract. The same as the other components, to interact with a multisig smart contract we can use either the MultisigController or the MultisigTransactionsFactory.

These operations can be performed using both the controller and the factory. For a complete list of supported methods, please refer to the autogenerated documentation:

• MultisigController
• MultisigTransactionsFactory

Deploying a Multisig Smart Contract using the controller

import * as fs from 'fs';
import * as path from 'path';
import { Abi, Account, Address, DevnetEntrypoint } from '@multiversx/sdk-core';

{
    const abiJson = fs.readFileSync('src/testdata/multisig-full.abi.json', { encoding: 'utf8' });
    const abi = Abi.create(JSON.parse(abiJson));
    const bytecode = new Uint8Array(fs.readFileSync('src/testdata/multisig-full.wasm'));

    // create the entrypoint and the multisig controller
    const entrypoint = new DevnetEntrypoint();
    const controller = entrypoint.createMultisigController(abi);

    const filePath = path.join("../src", "testdata", "testwallets", "alice.pem");
    const alice = await Account.newFromPem(filePath);

    // fetch the nonce of the network
    alice.nonce = await entrypoint.recallAccountNonce(alice.address);

    const transaction = await controller.createTransactionForDeploy(alice, alice.getNonceThenIncrement(), {
        quorum: 2,
        board: [
            alice.address,
            Address.newFromBech32("erd1spyavw0956vq68xj8y4tenjpq2wd5a9p2c6j8gsz7ztyrnpxrruqzu66jx"),
        ],
        bytecode,
        gasLimit: 100000000n,
    });

    // sending the transaction
    const txHash = await entrypoint.sendTransaction(transaction);

    // wait for transaction completion, extract multisig contract's address
    const outcome = await controller.awaitCompletedDeploy(txHash);

    const contractAddress = outcome.contracts[0].address;
}

Deploying a Multisig Smart Contract using the factory

import * as fs from 'fs';
import * as path from 'path';
import { Abi, Account, Address, DevnetEntrypoint } from '@multiversx/sdk-core';

{
    const abiJson = fs.readFileSync('src/testdata/multisig-full.abi.json', { encoding: 'utf8' });
    const abi = Abi.create(JSON.parse(abiJson));
    const bytecode = new Uint8Array(fs.readFileSync('src/testdata/multisig-full.wasm'));

    // create the entrypoint and the multisig factory
    const entrypoint = new DevnetEntrypoint();
    const factory = entrypoint.createMultisigTransactionsFactory(abi);

    const filePath = path.join("../src", "testdata", "testwallets", "alice.pem");
    const alice = await Account.newFromPem(filePath);

    // fetch the nonce of the network
    alice.nonce = await entrypoint.recallAccountNonce(alice.address);

    const transaction = await factory.createTransactionForDeploy(alice.address, {
        quorum: 2,
        board: [
            alice.address,
            Address.newFromBech32("erd1spyavw0956vq68xj8y4tenjpq2wd5a9p2c6j8gsz7ztyrnpxrruqzu66jx"),
        ],
        bytecode,
        gasLimit: 100000000n,
    });

    transaction.nonce = alice.getNonceThenIncrement();
    transaction.signature = await alice.signTransaction(transaction);
    // sending the transaction
    const txHash = await entrypoint.sendTransaction(transaction);
}
