Schema

Engine: MergeTree | Partition: toYYYYMM(block_date) | ORDER BY: block_date, project, version, source_chain

ColumnTypeDescription

Good to Know

  • Each row is directional — (Ethereum → Arbitrum) is separate from (Arbitrum → Ethereum).
  • Ethereum-centric: only covers bridges with Ethereum as one endpoint.
  • Not all bridge protocols are indexed — newer or smaller bridges may be missing.
