v0.4.0

[v0.4.0] - 2024-08-27

This release enables Envio to process contracts deployed using the latest versions of fuels-rs (v0.66.4) and forc (v0.63.5), with fuels-ts (v0.94.6) being used by the indexer.

• Optimized Indexing for OrderBook Contracts:
  • The indexer is now capable of efficiently indexing contracts of the OrderBook type, reducing the amount of computation required to track user balances and trade volumes.

Changes in Codebase

• Version Upgrades:

  • Updated envio package from 1.1.4-fuel to 2.2.4-fuel, enhancing indexing capabilities and compatibility with the Fuel ecosystem.

• GraphQL Schema Enhancements:

  • Introduced new fields like base_amount and quote_amount in multiple event types (OpenOrderEvent, CancelOrderEvent, TradeOrderEvent, DepositEvent, and WithdrawEvent) for more precise balance tracking and event handling.

• Refactored Handlers for Efficient Data Processing:

  • OrderBook Event Handling:

    • Updated handlers for OpenOrderEvent, CancelOrderEvent, TradeOrderEvent, DepositEvent, and WithdrawEvent to handle event processing based on user and asset balances.
    • Optimized logic for managing balance updates by removing dependency on marketConfig.ts and directly calculating balances.

  • Active Orders:

    • Improved the handling of active buy and sell orders by tracking their status (Active, Closed, Canceled) and updating corresponding user balances after each order action.

  • Order and Balance Updates:

    • Handlers now process order and balance changes synchronously to ensure real-time updates without requiring additional asset lookup through removed marketConfig.ts.

• Loader Improvements:

  • Optimized event loaders for CancelOrder, Deposit, OpenOrder, TradeOrder, and Withdraw to streamline balance loading and reduce unnecessary data lookups.

• Removed Unused Configuration:

  • Removed the unused marketConfig.ts file, which contained predefined constants for base and quote assets, as this is now dynamically handled within the event handlers.

Bug Fixes

• Balance Calculation Fixes:
  • Corrected balance calculation logic to ensure proper crediting and debiting of base_amount and quote_amount across various event handlers, improving accuracy in tracking users' balances.
