If a multi-sig transaction has been approved by the appropriate parties prior to the proposed transaction's expiration timestamp, it can be executed.
To execute a multi-sig transaction, submit a transaction to the exec action of the eosio.msig account.
In the example shown below userbbbbbbbb executes the changeowner proposal, previously proposed by useraaaaaaaa.
(async () => {
await api.transact({
actions: [{
account: 'eosio.msig',
name: 'exec',
authorization: [{
actor: 'userbbbbbbbb',
permission: 'active',
}],
data: {
proposer: 'useraaaaaaaa',
proposal_name: 'changeowner',
executer: 'userbbbbbbbb'
},
}]
}, {
blocksBehind: 3,
expireSeconds: 30,
broadcast: true,
sign: true
});
})();
