The models' case: The most complete Solana-native stack for address-level historical transaction data — the Enhanced Transactions API returns human-readable parsed history (types, token. The models' main caveat: Parsing coverage skews to common programs and it is a hosted commercial API — deep custom-program history or self-hosted control means falling back to. The strongest alternative is StreamingFast Substreams — Best option when you need to backfill the entire chain or a large window fast with custom logic — the Firehose/Substreams model streams historical.
