API
The Fireblocks API lets you estimate blockchain and transaction fees using the following endpoints:
Warning
You must check whether you have enough funds in the source account to pay for the estimated fees before submitting the transaction. If you do not have enough funds, the transaction may fail and you will receive the DROPPED_BY_BLOCKCHAIN error in the Console, or the Failed: Insufficient funds for fee status via the API.
Testnet
The high fee estimation for BTC_TEST is mainly due to how Testnet works. Unlike Mainnet, Testnet is often used for experimenting, and users frequently set unnecessarily high fees. This causes artificial fee spikes, which can make estimations look higher than expected. Note that you can always set a custom fee to better suit your testing needs.
