Withdraw from Wallet - Custodial Multisig

Overview

You initiate withdrawals from custodial multisignature wallets by submitting transaction details to BitGo. BitGo uses the data you pass to construct an unsigned transaction that wallet admins can approve. After video verification, a BitGo Trust operator signs the transaction with the user key. Then a different BitGo Trust operator downloads and signs the transaction in the BitGo Offline Vault Console (OVC). BitGo then uploads and broadcasts the transaction.

Step Result

If your withdrawal doesn't require approval, then BitGo receives the unsigned transaction. If you Create Wallet Policies to require approvals on withdrawals, the transaction remains in a pending-approval status until a wallet admin approves it.

Log in to BitGo and schedule video ID verification. Once verification completes, BitGo signs the transaction and broadcasts it to the blockchain.
