What problem does it solve?

This skill handles the final-mile on-chain operations that developers and traders need to complete transactions: estimating gas, simulating transactions to detect failures, broadcasting pre-signed transactions, and tracking broadcast orders across many chains. It removes the manual, error-prone steps of preparing, testing, and sending transactions and surfaces clear diagnostics and order tracking identifiers.

Core Features & Use Cases

• Gas price and gas-limit estimation for EVM and non-EVM chains to choose fees and avoid failed transactions.
• Transaction simulation (dry-run) to detect reverts, estimate gasUsed, and inspect asset changes before committing on-chain.
• Broadcast signed transactions and track orders by returning an orderId and txHash so the user can monitor final settlement status.
• Use case: Simulate a complex contract interaction, adjust fees based on suggested base fee and priority fee, broadcast the signed payload, then poll order status until confirmed.

Quick Start

Ask the assistant to broadcast a pre-signed transaction by providing the signed payload, your wallet address, and the chain, for example: onchainos gateway broadcast --signed-tx <signed_hex_or_base58> --address <your_address> --chain ethereum
