FAQPage Schema

How do I broadcast a pre-signed transaction on Ethereum or Solana?▼

To broadcast pre-signed transactions on Ethereum or Solana, provide the transaction hex, sender address, and target chain to receive an orderId and txHash for tracking.

Can I simulate an on-chain transaction before broadcasting to validate gas?▼

Yes, you can simulate on-chain transactions as a dry-run to validate gas estimates and check for errors prior to the actual broadcast across supported chains.

Does this tool support gas estimation for multiple networks like Arbitrum and Base?▼

Yes, gas estimation and gas price retrieval are supported across multiple networks including Arbitrum, Base, BSC, Ethereum, and Solana.

What is the best way to track broadcast orders for signed payloads?▼

Tracking broadcast orders requires submitting a signed payload and target chain, which returns an orderId and txHash to monitor the transaction status.

Can I use MEV protection options when broadcasting cross-chain transactions?▼

Yes, broadcasting cross-chain transactions supports MEV protection options to help prevent front-running and prioritize transaction inclusion on supported networks.

How does error handling work for failed on-chain transaction broadcasts?▼

Error handling for failed broadcasts captures simulation and network failures, returning error details with the orderId to help diagnose cross-chain broadcast issues.
