Direct behavior

Requests for older chain data are automatically routed to providers with full chain history. This covers blocks, transactions, receipts, and logs independently of historical account state.

Requests using latest follow Direct’s reference-block rules. The selected reference is preserved during recovery; separate requests can see a newer reference.

For providers

Support the required recent chain-history service. Advertise full chain history only when all included method families and lookup indexes work back to genesis.

See provider qualification for checks and continued eligibility.
