From 43e68440b62a27c68df7c732d38a60d0811a919d Mon Sep 17 00:00:00 2001 From: BernardOnuh Date: Sat, 20 Jun 2026 11:26:06 +0100 Subject: [PATCH] feat(treasury): add automated fee sweep service with daily cron and threshold trigger Implements TreasuryService, treasury_sweeps table, exponential backoff retry, and Sentry alerting on 3 consecutive failures. - TreasuryService with getTreasuryBalance() and sweepTreasury() methods - Daily cron (0 2 * * *) and 10-minute threshold balance checks - Exponential backoff retry: 1s, 2s, 4s before alerting - treasury_sweeps table for full audit trail - Sentry captureException on 3 consecutive failures - Idempotency check to prevent duplicate sweeps - Complete unit test coverage with 20+ test cases Closes #28 --- backend/.env.example | 20 ++ backend/src/cron/treasurySweep.cron.ts | 71 +++++ .../0001_create_treasury_sweeps_table.sql | 30 ++ .../src/db/schema/treasurySweeps.schema.ts | 32 ++ .../repositories/TreasurySweepRepository.ts | 137 +++++++++ backend/src/services/TreasuryService.ts | 215 ++++++++++++++ .../__tests__/TreasuryService.test.ts | 275 ++++++++++++++++++ 7 files changed, 780 insertions(+) create mode 100644 backend/src/cron/treasurySweep.cron.ts create mode 100644 backend/src/db/migrations/0001_create_treasury_sweeps_table.sql create mode 100644 backend/src/db/schema/treasurySweeps.schema.ts create mode 100644 backend/src/repositories/TreasurySweepRepository.ts create mode 100644 backend/src/services/TreasuryService.ts create mode 100644 backend/src/services/__tests__/TreasuryService.test.ts diff --git a/backend/.env.example b/backend/.env.example index fbfa9397..bce58fc6 100644 --- a/backend/.env.example +++ b/backend/.env.example @@ -68,3 +68,23 @@ MAX_MARKET_POOL_XLM=100000 MAX_PLATFORM_EXPOSURE_XLM=500000 # Admin email to receive risk alert emails ADMIN_EMAIL=admin@boxmeout.app + +# ── Treasury Sweep Configuration ────────────────────────────── +# Balance threshold (in XLM) that triggers an immediate sweep +TREASURY_SWEEP_THRESHOLD_XLM=1000 + +# Destination wallet address where swept Treasury funds are sent +TREASURY_WALLET_ADDRESS=GXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX + +# Stellar contract ID for the Treasury smart contract +TREASURY_CONTRACT_ID=CAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABSC4 + +# ── Treasury Sweep Configuration ────────────────────────────── +# Balance threshold (in XLM) that triggers an immediate sweep +TREASURY_SWEEP_THRESHOLD_XLM=1000 + +# Destination wallet address where swept Treasury funds are sent +TREASURY_WALLET_ADDRESS=GXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX + +# Stellar contract ID for the Treasury smart contract +TREASURY_CONTRACT_ID=CAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABSC4 diff --git a/backend/src/cron/treasurySweep.cron.ts b/backend/src/cron/treasurySweep.cron.ts new file mode 100644 index 00000000..786afd1e --- /dev/null +++ b/backend/src/cron/treasurySweep.cron.ts @@ -0,0 +1,71 @@ +import cron from 'node-cron'; +import { logger } from '../utils/logger'; +import { TreasuryService } from '../services/TreasuryService'; + +let dailyCronTask: cron.ScheduledTask | null = null; +let thresholdIntervalTask: NodeJS.Timeout | null = null; + +/** + * Register the Treasury sweep cron jobs + * 1.
