To broadcast signed on-chain transactions across multiple blockchains, submit the pre-signed transaction payload to the gateway. The system handles the network broadcast and returns an order ID to track the transaction status.

Estimate gas and simulate a transaction by calling the designated gas and simulate commands before broadcasting. This evaluates the gas limit and execution path to prevent failures and optimize costs for the signed transaction.

You can track the status of broadcasted blockchain transactions using the generated order ID. The gateway monitors the on-chain execution and updates the order status to confirm final transaction results.

The on-chain gateway supports MEV protection parameters during transaction simulation and broadcast when available on the target blockchain. This integrates anti-MEV logic into the multi-chain workflow for safer transaction execution.

The best way to manage multi-step on-chain workflows is to use a gateway that integrates gas estimation, simulation, and order tracking. This completes multi-step operations like swaps by linking broadcast and monitoring processes.

Use a pre-signed transaction broadcast when managing multi-chain workflows that require external gas estimation, transaction simulation, and continuous order monitoring. This approach separates signing from network broadcast for safer execution.
