signet-extract

Extraction logic for Signet. This crate contains functions that traverse reth Chain objects and extract Signet-specific data from them.

What's new in Signet?

Signet nodes watch Ethereum for specific events, and use these events to trigger actions on Signet. These actions are processed by the Signet EVM during block processing.

There are 4 types of events that trigger actions on Signet:

• BlockSubmitted - Retrieve builder-submitted transactions from an Ethereum blob, and execute them on Signet.
• Enter- Mint ETH on Signet.
• EnterToken - Mint tokens on Signet.
• Transact - Execute a transaction on Signet.

Another event affects Signet's [conditional transactions]. The Fill event is used to populate the aggregate fills for conditional transactions. This event is emitted by the Orders contract on Ethereum when a trade is executed, and then used to enforce the conditional invariant on Signet.

What's in this crate?

The Extractor object traverses a Chain and produces a Extracts per block. This object contains all relevant events that occured in the block, as well as a populated AggregateFills.
