Custom Tables

Define your own tables in ~/.mevlog/config.toml, populated from indexed logs matching a topic0. Query them alongside the built-in tables.

What they are

• TODO: config-defined tables in the local txs DB, built from matching logs.
• TODO: tracked in the custom_tables meta table by name + fingerprint.

Defining a table

• TODO: [tables.<name>] block, topic0, optional chains, optional addresses emitter filter.
• TODO: example TOML (Uniswap V2 Swap).

Column mapping

• TODO: source = topic1..topic3 or data[start:end] (0-based, end-exclusive; ABI word n is data[n*32:(n+1)*32]).
• TODO: types - address (20-byte BLOB), uint256 (32-byte BE BLOB, works with u256_sum / format_ether), bytes (verbatim slice).
• TODO: caveat - dynamic ABI params (string/bytes) store the offset word, not the value.

Rebuilding after edits

• TODO: mevlog update-db --rebuild-tables --chain-id <id>.
• TODO: fingerprint change triggers rebuild; name validation rejects reserved names.

Querying custom tables

• TODO: custom table names are allowlisted for --sql reads alongside transactions / blocks / logs.
