Using a custom authority provider within eosjs for Greymass Fuel
Raw
authorityprovider.js

// This provider overrides the checks on all keys,
// allowing a partially signed transaction to be
// broadcast to the API node.

// Iterate over the actions and authorizations
transaction.actions.forEach((action, ti) => {

// If the authorization matches the expected cosigner
// then remove it from the transaction while checking
// for what public keys are required

&& auth.permission === 'cosign'
) {
delete transaction.actions[ti].authorization.splice(ai, 1)
