Welcome

ETHGas Orderflow Engine accepts private transactions on Ethereum Mainnet, shares safe decoded orderflow with authorized searchers, and forwards eligible transactions and backrun bundles to configured builders.

The engine is designed for two participants:

• Originators submit signed transactions or bundles without broadcasting them to the public mempool.

• Searchers receive unsigned decoded orderflow and submit backruns.

Start here

• New integrators: follow the Quickstart.

• Sending orderflow: read Originators.

• Building backruns: read Searchers.

The engine admits structurally valid signed transactions; it does not simulate them or guarantee on-chain inclusion. Final acceptance is determined by the configured builders.
