Backfill behaviour

  • Solana / EVM archival data backfilled from genesis where feasible.
  • New chains start with ≥ 30 days of backfill at launch, full history streamed in within the first 90 days.
  • Reorgs cause rewrites of the affected slot/block in all downstream streams; consumers should be idempotent on (chainId, txHash) + logIndex.
