By Wallet Type

Withdraw from Wallet - Custody Multisig

Overview

You initiate withdrawals from custody 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 Bank & Trust operator signs the transaction with the user key. Then a different BitGo Bank & Trust operator downloads and signs the transaction in the BitGo Offline Vault Console (OVC). BitGo then uploads and broadcasts the transaction.


Note

You can only transact from custody wallets in the production environment. BitGo doesn't sign transactions from custody wallets in testnet due to the enhanced security protocols that are required. You can still create testnet custody wallets and initiate transactions, but these transactions remain in an unsigned state.

1. Initiate Transaction

Endpoint: Initiate a Transaction

export COIN="<ASSET_ID>"
export WALLET_ID="<YOUR_WALLET_ID>"
export ACCESS_TOKEN="<YOUR_ACCESS_TOKEN>"
export ADDRESS="<DESTINATION_ADDRESS>"
export AMOUNT="<AMOUNT_IN_BASE_UNITS>"
export WALLET_PASSPHRASE="<YOUR_WALLET_PASSPHRASE>"
export VIDEO_APPROVER_1="<PUBLIC_ID_1>"
export VIDEO_APPROVER_2="<PUBLIC_ID_2>"

curl -X POST \
  https://app.bitgo-test.com/api/v2/$COIN/wallet/$WALLET_ID/tx/initiate \
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $ACCESS_TOKEN" \
  -d '{
    "recipients": [
        {
          "amount": "'"$AMOUNT"'",
          "address": "'"$ADDRESS"'"
        }
      ],
    "videoApprovers": [
      "'"$VIDEO_APPROVER_1"'",
      "'"$VIDEO_APPROVER_2"'"
    ]
  }'

Step Result

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

2. (Optional) Approve Transaction

Endpoint: Update Pending Approval

export COIN="<ASSET_ID>"
export APPROVAL_ID="<APPROVAL_ID>"
export ACCESS_TOKEN="<YOUR_ACCESS_TOKEN>"
export OTP="<OTP>"

curl -X POST \
  http://api/v2/$COIN/pendingapprovals/$APPROVAL_ID
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $ACCESS_TOKEN" \
  -d '{
    "state": "approved",
    "otp": "'"$OTP"'"
}'

Step Result

Once approved, BitGo rebuilds the unsigned transaction, applying the most up-to-date fees.

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