HIP-3 upgrade support
The indexer now tracks two new L1 actions tied to the HIP-3 upgrade:
  • agentSendAsset — agent transfers between dexes for the same user.
  • hip3LiquidatorTransfer — deposit/withdraw of principal on the backstop of a HIP-3 dex.

​
New endpoints

All grouped under /evm/hip3/backstop/*. The backstop address for a dex is 0x4000…00 + dex_index.Principal flows — built from local hip3LiquidatorTransfer rows:
  • GET /evm/hip3/backstop/transfers — Filterable list of backstop principal transfers (filters: dex, signer, is_deposit, time range).
  • GET /evm/hip3/backstop/transfers-summary — Per-dex aggregate: total_deposited_usdc, total_withdrawn_usdc, net_principal_usdc, unique_signers.
On-chain activity — combine principal flows with fills observed at the backstop address:
  • GET /evm/hip3/backstop/health — Health overview of every observed HIP-3 backstop. Returns one row per dex (combined principal + fill counters, last/first fill, fees paid, active coins).
  • GET /evm/hip3/backstop/{dex}/health — Same payload for a single dex. Returns 404 if no backstop activity has ever been observed for that dex.
  • GET /evm/hip3/backstop/{dex}/fills — Paginated stream of raw fills absorbed by the backstop. Filters: coin, side, time range.

​
Updated endpoints

  • GET /evm/ledger/transfers — Response extended with source_dex and destination_dex (populated for agentSendAsset). action_type=agentSendAsset is now a supported filter value.
  • GET /evm/user/{address}/ledger-events — New agent_send event type, exposing source_dex and destination_dex.
