What's New

External Delta Orders

New order type that delegates token handling to an external handler contract, enabling complex DeFi strategies (e.g. Aave collateral swaps, debt swaps, repay-with-collateral).

New SDK methods:

  • buildExternalDeltaOrder — build a signable external order
  • signExternalDeltaOrder — EIP-712 sign
  • postExternalDeltaOrder — submit to API
  • preSignExternalDeltaOrder — on-chain pre-sign for smart contract wallets
  • submitExternalDeltaOrder — all-in-one build + sign + post

New types: ExternalDeltaOrder, SignableExternalOrderData, OnChainOrderType

Query support: getDeltaOrders now accepts onChainOrderType: 'ExternalOrder' filter.

Documentation: EXTERNAL_ORDERS.md

Slippage parameter for Delta order building

buildDeltaOrder, submitDeltaOrder, buildExternalDeltaOrder, and submitExternalDeltaOrder now accept a slippage parameter (in bps). The SDK auto-computes
srcAmount/destAmount from the deltaPrice response, removing the need for manual slippage calculation.

Default order expiry changed

Default Delta order expiry reduced from 1 hour to 10 minutes.

Deprecations

  • Limit Order APIs (constructAllLimitOrdersHandlers and related methods) are now marked as @deprecated.
  • NFT Order APIs (constructAllNFTOrdersHandlers and related methods) are now marked as @deprecated.

Bug Fixes

  • Partner fee fallback now correctly converts percent to bps.

Internal

  • Centralized partner-fee and amount resolution into shared helpers.
  • Pre-signature ABI deduplicated across Delta and External order modules.
  • Removed legacy Limit Order and NFT Order tests and test fixtures.
