All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog.

[Unreleased]

Added

  • Outcome (prediction) market support: OutcomeMeta, OutcomeInfo, OutcomeQuestion, OutcomeSideSpec types
  • HttpClient::outcome_meta() and standalone hypercore::outcome_meta() for querying HIP-4 markets
  • HyperCore WS subscriptions for userEvents, userTwapSliceFills, userTwapHistory, activeAssetData, and webData2
  • New typed WS payloads for user events, TWAP slice/history streams, and active asset data
  • Forward-compatible fallback parsing for unknown userEvents payload variants
  • New example: examples/hypercore/websocket-user-events.rs

Changed

  • Extended WebSocket docs/snippets in README and crate docs to include advanced user streams
  • Added serde test coverage for the new WS channels and payload schemas

[v0.1.5] - 2026-01-12

Added

  • Added Cancel variant to OkResponse enum for order cancellation responses
  • Added test case for cancel response deserialization
  • Added credentials example showing common argument patterns across examples
  • Made signing module public (pub mod signing)

Changed

  • Breaking: Morpho APY calculations now use generic types for high precision arithmetic
    • PoolApy and VaultApy are now generic over T128 type parameter
    • apy() methods require conversion functions to handle custom numeric types (f64, Decimal, etc.)
    • Enables arbitrary precision calculations for financial computations
  • Refactored examples to use common credential and argument handling patterns
  • Updated morpho examples to use new generic APY API with explicit conversions

Fixed

  • Fixed API type structs for cancellation and modification responses

Dependencies

  • hypecli v0.1.3: Updated dependencies including alloy and hypersdk versions

Files Changed: 24 files, +556 insertions, -249 deletions

[v0.1.4] - 2026-01-10

Added

  • Created new types/api.rs module with core API request/response types (788 lines)
  • Added types/solidity.rs module for Solidity type conversions
  • Added signature recovery functionality to Action enum (recover() method)
  • Added prehash() method to Action for obtaining signing hashes without signing
  • Added methods to HttpClient: multi_sig_config(), api_agents()

Changed

  • Breaking: Removed Signable trait in favor of methods directly on Action enum
    • Actions now implement sign(), sign_sync(), prehash(), and recover() directly
    • Simplified signing API with unified interface through Action enum
  • Breaking: Split types.rs into modular structure: types/mod.rs, types/api.rs, types/solidity.rs
  • Reorganized HTTP client to use new type organization
  • Refactored signing module, reducing from 700+ lines to ~26 lines by moving logic to Action
  • hypecli: Switched to simple P2P connections instead of gossip protocol in iroh integration
  • hypecli: Enhanced multisig handling with improved error handling and flow

Documentation

  • Added comprehensive module-level documentation for types/api.rs
