Create, cancel, drop, and query digital-asset transactions across all supported chains. Every transaction passes the workspace Policy Engine, is signed by the MPC quorum, and is broadcast under Fireblocks' fee-bump-and-rebroadcast logic. Supports transfers, raw signings, typed-message signings, contract calls, drop-and-replace, fee estimation, validate-address, and approval-request management.

description: "Creates a new transaction. This endpoint can be used for regular Transfers, Contract Calls, Raw & Typed message signing.\n- For Transfers, the required parameters are: `assetId`, `source`, `destination` and `amount`.\n\n- For Contract Calls, the required parameters are: `operation.CONTRACT_CALL`, `assetId` (Base Asset), `source`, `destination`, `amount` (usually 0) and `extraParameters` object with `contractCallData` string.\n- For Solana Program Calls, the required parameters are: `operation.PROGRAM_CALL`, `assetId` (SOL/SOL_TEST), `source`,\n and `extraParameters` object with `programCallData` key while the value is a Base64 encoded unsigned serialized Solana transaction object.\n\n\n- Typed Message Signing is supported for the following asset IDs: 'ETH', 'BTC' and 'TRX'. [Typed Message Signing Guide](https://developers.fireblocks.com/docs/typed-message-signing-overview).\n- To create ZEC transaction, please call [Get unspent UTXO Input endpoint](https://developers.fireblocks.com/reference/getunspentinputs) to get the amount and use it as an input under `networkfee` on this endpoint. Please use this formula `(0.0001 + 0.00005*N) where N is the number of inputs` to calculate the fee needed and use it as an input under networkFee field\n- When using `maxFee` and a boost is needed, the user should set a custom `gasPrice` to force the override.\nLearn more about Fireblocks Transactions management in the following [guide](https://developers.fireblocks.com/reference/create-transactions).\n</br>Endpoint Permission: Admin, Signer, Editor."
