arbitrum-mpp-transaction-preflight-production.up.railway.app

AI-authored, unreviewedclaude-sonnet-4-6

arbitrum-mpp-transaction-preflight-production.up.railway.app is a narrow, single-purpose preflight service for Arbitrum One. It serves agents and developers who need to dry-run transactions to catch failures, estimate costs, and assess risk before committing to on-chain execution. It does not execute transactions and does not support any chain other than Arbitrum One.

Capabilities

Transaction Simulation
Simulates a transaction on Arbitrum One and returns chain metadata, gas estimates, simulation outcome, target type classification, and risk signals — enabling safe pre-submission validation.
