Celo uses the same fee address structure as Ethereum. Each enterprise has a fee address that is used to pay for transaction fees on all Celo wallets in that enterprise. The BitGo website dashboard displays the fee address, and you must fund it before creating a wallet, address, or sending a transaction.

If the enterprise fee address has an insufficient balance, you cannot create new wallets or addresses, and cannot send transactions until you fund the fee address. If the balance of your fee address gets too low, you cannot fund it with one of your own Celo wallets (because you cannot send transactions from your Celo wallet). BitGo recommends that you create and fund a non-BitGo Celo account, so you can use it to fund your BitGo enterprise fee address. Any open source Celo wallet can be used to create an account.

Note: A best practice is to create and fund a non-BitGo Celo account to fund your BitGo enterprise fee address.

Note: The fee address is a single-signature account, and BitGo creates and owns the private key. You cannot send assets out of the fee address once you have sent them in. There is a feeAddress field under the CoinSpecific key for Celo wallets. Use this address to pay the fees for creating transactions and addresses.

Generating wallets

bitgo
  .coin('tcelo')
  .wallets()
  .generateWallet({
    label: 'My Test Wallet',
    passphrase: 'secretpassphrase1a5df8380e0e30',
    enterprise: '5612c2beeecf83610b621b90964448cd',
  })
  .then(function (wallet) {
    // print the new wallet
    console.dir(wallet);
  });

LABEL="My Test Wallet"
PASSPHRASE="secretpassphrase1a5df8380e0e30"

curl -X POST \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $ACCESS_TOKEN" \
-d "{ \"label\": \"$LABEL\", \"passphrase\": \"$PASSPHRASE\" }" \

Before you can use a Celo wallet, it must be initialized on the Celo blockchain. A funding transaction must first be sent to the wallet address. When BitGo detects this funding transaction, it automatically sends another initialization transaction to set up the signers and the home domain of the account.

Until the network confirms the initialization transaction, the wallet is not ready for use, and the receive address is not exposed in the API. This is to protect users from losing assets by sending to a wallet that does not exist on the network.

Warning: Do not use a Celo wallet while it is initializing or you may lose assets.

Creating addresses

bitgo
  .coin('tcelo')
  .wallets()
  .getWallet({ id: '585c51a5df8380e0e3082e46' })
  .then(function (wallet) {
    return wallet.createAddress();
  })
  .then(function (newAddress) {
    // print new address details
    console.dir(newAddress);
  });

WALLET=585c51a5df8380e0e3082e46

curl -X POST \
-H "Authorization: Bearer $ACCESS_TOKEN" \
https://app.bitgo-test.com/api/v2/tcelo/wallet/$WALLET/address

As with Celo wallets, Celo address must be initialized on the Celo blockchain before they can be used.

To deploy a receive address contract, BitGo sends a transaction on the Celo network. Remember that you must fund the fee address. Like wallet creation process, a Celo address is not immediately usable and so the caller of this function must wait for the network to confirm the initialization transaction before attempting to fetch, or send to, the address.

Warning: Do not use a Celo address while it is initializing or you may lose assets.

Balances

CELO (CELO) is the native asset of the Celo blockchain. The base unit of CELO is wei:

  • 1 wei is (10-18) or 0.000000000000000001 CELO.
  • 1 CELO is (1018) or 1000000000000000000 wei (1 quintillion).

BitGo supports balances in string format: balanceString, confirmedBalanceString, and spendableBalanceString.

Transactions

The BitGo Celo multisig contract currently only supports one sender and one recipient so the sendMany is not supported.
