Base - Tatum API

Send BASE or fungible tokens (ERC-20) from account to account

/v3/base/transaction

2 credits per API call

Send BASE or Tatum-supported fungible tokens (ERC-20) from account to account.

NOTE: Sending the fungible tokens is supported only on the mainnet.

Signing a transaction
When sending BASE, 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.
