4 credits per API call
Send ARB or ERC-20-equivalent ARB tokens from a virtual account (even from a virtual account without deposit addresses adssigned) to the Arbitrum blockchain.
The recipient has to agree in advance to receive assets because Arbitrum charges users for storing assets on their addresses, and an Arbitrum blockchain address by default does not receive assets unless explicitly agreed. Before sending any asset from a virtual account to the blockchain, make sure that the recipient has agreed to receive the assets to their address.
Sending Arbitrum assets creates an internal Tatum withdrawal request with an ID. If everything works as expected, the withdrawal request is marked as complete and a transaction ID is assigned to it.
- If a server connection is unavailable, the withdrawal request is cancelled.
- If the transfer to the blockchain is successful, but the Tatum infrastructure cannot be accesses, the ID of the blockchain transaction is returned and you have to complete the withdrawal request manually. Otherwise, all other withdrawals will be pending.
Signing a transaction
When sending ARB or ERC-20-equivalent ARB tokens, you are charged a fee for the transaction, and you must sign the transaction with the private key of the blockchain address from which the fee will be deducted.
Providing the private key in the API is not a secure way of signing transactions, because the private key can be stolen or exposed. Your private keys should never leave your security perimeter. You should use the private keys only for testing a solution you are building on the testnet of a blockchain.
For signing transactions on the mainnet, we strongly recommend that you use the Tatum Key Management System (KMS) and provide the signature ID instead of the private key in the API. Alternatively, you can use the Tatum JavaScript client.
