From e352d96904409577e5738bddacb05a8547c5baca Mon Sep 17 00:00:00 2001 From: BigJohn-dev Date: Thu, 23 Jul 2026 15:08:20 +0100 Subject: [PATCH] feat: add payout and split routes for API - Implemented payout routes to fetch payout history based on split ID with pagination and optional token filtering. - Created split routes to retrieve all splits, specific split details, and balances associated with a split. - Added server setup to integrate new routes into the API. feat: configure database migration system - Established a migration system to manage database schema changes. - Created migration files for events, splits, payout history, and ingestion state tables. - Implemented migration logic to apply pending migrations and maintain a record of applied migrations. feat: implement ingestion and reconciliation processes - Developed ingestion logic to fetch and decode events from the Stellar network, storing them in the database. - Implemented reconciliation logic to compare on-chain balances with database records, detecting discrepancies and posting webhooks for drifts. feat: define types for events, splits, payouts, and reconciliation - Created TypeScript types for various entities including events, splits, payouts, and reconciliation results to ensure type safety across the application. chore: set up TypeScript configuration and testing framework - Configured TypeScript compiler options and included necessary settings for module resolution and output. - Set up Vitest for testing with a configuration file to specify test environment and include patterns.
