Transaction Management

Move assets at the speed of code

Build, sign, execute, and monitor the full transaction lifecycle across every major blockchain through safe and reliable APIs.

Transaction Management interface
Move everything onchain

Trade, swap, stake, pay, settle, and call contracts through one API integrated to the ecosystem.

Execute with certainty

Control every step of the transaction with simulation, idempotency, retries, and recovery built in.

Know before you sign

Decode, simulate, and evaluate transactions to catch policy breaches, errors, anomalies, and risk.

Keep one source of truth

Centralize records, analytics, and exportable logs across wallets, transactions, and every action.


Global settlement is moving onchain

Equip your front office with a unified execution layer for all digital assets.

Choose your
execution path

Transfers, custom payloads, raw signatures. Build with the level of control your workflow requires.

Transfer

Send assets with one call. Specify the type, amount, and recipient. We do the rest.

Sign & broadcast

Build the transaction. Control fees, nonce, and call data. We sign and broadcast it.

Sign

Execute freely on your side. You handle the transaction and broadcasting. We sign it.
