A straightforward broadcasting layer for multi-chain transactions. Handles gas estimation, transaction simulation, broadcasting signed txs, and order tracking across Ethereum, Solana, Base, BSC, Arbitrum, Polygon, and 20+ other chains. Built to work downstream from swap execution: you get transaction data from opentrade-dex-swap, sign it locally, then use this to actually send it on-chain and monitor status. The CLI enforces a router discovery step upfront, which adds overhead but ensures you're using an active trading router. Covers the unglamorous final mile of getting transactions onto chains, with simulation as a safety valve before broadcast. Not for quotes or swaps, just the send-and-track piece.
