Protocol Fingerprint Expansion

3 changes in the newest release, focused on transaction classification fidelity, broader protocol coverage, and safer downstream automation.

  • Added 50 new protocol fingerprints across Morpho, Spark, Ethena, Ether.fi, Pendle, and Berachain bridge flows.
  • Improved action classification for complex multicall bundles so router-heavy swaps collapse into a single intent.
  • Introduced a fake token safety signal for contracts that mimic blue-chip symbols while redirecting approvals.

Cursor Pagination Contract Update

  • Replaced `page` and `limit` parameters on transaction history endpoints with opaque `cursor` tokens.
  • Response envelopes now return `next_cursor` and `prev_cursor` instead of `nextPage` metadata.
  • Decoded event payloads are included by default; clients that depended on `includeDecodedLogs=true` should switch to `event_mode`.
