From f6a80ee25842de324688b595ebfdb633823c2584 Mon Sep 17 00:00:00 2001 From: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Date: Tue, 16 Jun 2026 15:06:04 +0000 Subject: [PATCH 01/17] =?UTF-8?q?feat:=20Mark=20Lane=20integration=20?= =?UTF-8?q?=E2=80=94=20FX=20liquidity=20bridge,=20KYC=20compliance=20passp?= =?UTF-8?q?ort,=20settlement=20reconciliation?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Mark Lane (marklane.io) is a FINTRAC-registered Canadian MSB for FX professionals. This integration enables CAD→Africa corridors via Mark Lane's on-ramp platform. TypeScript: - markLaneClient.ts: API client with circuit breaker for FX quotes, transfers, KYC passport, nostro balances, webhooks. Graceful mock fallback when API key unavailable. - markLaneRouter.ts: tRPC router with 18 endpoints — corridor discovery, FX quotes, transfer lifecycle, KYC passport (FINTRAC↔CBN/FCA), nostro monitoring, FX professional channel, webhook ingestion, analytics. - 31 integration tests (10 scenarios) — all passing. - 5 PostgreSQL tables for Mark Lane data persistence. - 10 Kafka event types for Mark Lane audit trail. - TigerBeetle ledger entries for all financial mutations. Go (port 8128): go-marklane-fx-bridge - Composite FX quote engine (Mark Lane CAD rates × RemitFlow African rates) - 8 corridor routes (CA-NG, CA-GH, CA-KE, CA-ZA, CA-SN, CA-TZ, CA-UG, CA-CM) - Nostro position tracking with rebalance detection - Circuit breakers on both Mark Lane and RemitFlow rate APIs - Background rate refresh loop (30s interval) - Kafka event emission via Dapr, Prometheus metrics Rust (port 8129): rust-kyc-compliance-bridge - Cross-jurisdictional KYC passport issuance & verification - 3 compliance mappings (FINTRAC↔CBN, FINTRAC↔FCA, CBN↔FINTRAC) - Document equivalence tables (Canadian passport↔international passport, etc.) - Transaction screening with amount-based risk thresholds (FINTRAC CAD 10K, CBN NGN 5M) - SAR filing endpoint for suspicious activity reports - Prometheus compliance metrics Python (port 8130): python-settlement-reconciliation - Bilateral nostro position tracking (Mark Lane ↔ RemitFlow) - Automated reconciliation with settlement instruction generation - Regulatory report generation (FINTRAC LCTR, CBN AML reports) - Daily summary endpoint - Background auto-reconciliation (6-hour cycle) - Prometheus settlement metrics Co-Authored-By:

8bit BREAKING CHANGE: External API clients now throw in production (NODE_ENV=production) when API keys are not configured. In development, mock fallbacks still work. Phase 1.1: Fail-closed mock fallbacks - kycDocumentVerification.ts: Onfido/Smile throw when keys missing in production - circleClient.ts: Circle throws when CIRCLE_API_KEY missing in production - complianceEngine.ts: OFAC/Chainalysis/Notabene fail-closed in production - fireblocksCustody.ts: Fireblocks throws when API key missing in production - In dev (NODE_ENV != production): existing mock behavior preserved Phase 1.2: SQL parameter binding - featurePersistence.ts: persistFeatureRecord uses parameterized queries - loadFeatureRecord: uses sql template literals with bound params - deleteFeatureRecord: uses sql template literals with bound params - updateFeatureRecord: uses parameterized .. placeholders Phase 1.3: Temporal worker deployment - docker-compose.yml: Added Temporal server, UI, and worker containers - Worker connects to temporal:7233, task queue remitflow-main - Health endpoint on port 8080 for readiness probes Phase 1.4: HashiCorp Vault integration - server/lib/vaultClient.ts: Full Vault client with: - K8s, AppRole, and token authentication - KV v2 secret retrieval with caching - Transit encryption/decryption for PII - Dynamic database credentials - Automatic token renewal - ops/vault-init.sh: One-command Vault setup script - Configures KV v2, Transit, Database engines - Creates AppRole with scoped policy - Seeds placeholder secrets structure Phase 1.5: PgBouncer connection pooling - docker-compose.yml: PgBouncer service (port 6432) - Transaction pooling mode - 1000 max client connections → 50 backend connections - k8s/pgbouncer.yaml: Full K8s manifest - 2-replica Deployment with PDB - Prometheus metrics exporter sidecar - ConfigMap for pgbouncer.ini Phase 1.6: Environment templates - .env.sandbox: Template with all sandbox provider links and free-tier info - .env.production.template: Full production env var reference - k8s/secrets.yaml: Updated with Vault/Temporal/provider vars + security warning Verification: - TypeScript: 0 errors (npx tsc --noEmit) - Tests: 1526/1528 passing (2 pre-existing failures unrelated to these changes) Co-Authored-By: Patrick Munis --- .env.production.template | 114 ++++++++ .env.sandbox | 94 +++++++ docker-compose.yml | 95 +++++++ k8s/pgbouncer.yaml | 217 ++++++--------- k8s/secrets.yaml | 34 ++- ops/vault-init.sh | 193 ++++++++++++++ server/_core/circleClient.ts | 14 +- server/_core/complianceEngine.ts | 83 +++++- server/_core/featurePersistence.ts | 60 +++-- server/_core/fireblocksCustody.ts | 7 + server/_core/kycDocumentVerification.ts | 62 ++++- server/lib/vaultClient.ts | 338 ++++++++++++++++++++++++ 12 files changed, 1134 insertions(+), 177 deletions(-) create mode 100644 .env.production.template create mode 100644 .env.sandbox create mode 100755 ops/vault-init.sh create mode 100644 server/lib/vaultClient.ts diff --git a/.env.production.template b/.env.production.template new file mode 100644 index 00000000..8086e5f9 --- /dev/null +++ b/.env.production.template @@ -0,0 +1,114 @@ +############################################################################### +# RemitFlow — Production Environment Template +# +# Copy to .env.production and fill in real values. +# In Kubernetes, these map to k8s/secrets.yaml. +# In Vault-managed deployments, most values are fetched dynamically. +# +# REQUIRED = Must be set before production deploy +# OPTIONAL = Has sensible defaults or graceful degradation +# VAULT = Fetched from Vault in production (set here for local testing) +############################################################################### + +# ── Core Application ───────────────────────────────────────────────────────── +NODE_ENV=production +PORT=3000 +APP_URL=https://remitflow.app #

charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes 7 issues in the ML fraud scoring pipeline: 1. Temporal fraud activity: source_country derived from input.fromCurrency (was hardcoded "NG" — every sender scored as Nigerian) 2. Temporal gRPC fraud call: fromCountry derived dynamically (was "NG") 3. Temporal fraud activity: user_kyc_level looked up from DB (was hardcoded 1) 4.

    • +
+

You are responsible for maintaining the accuracy of your account information. We reserve the right to suspend accounts with outdated or incorrect information.

  • Foreign exchange services at competitive rates
    • +
  • Bill payment and airtime top-up services
    • +

    • +
  • Business payment services (batch payments, recurring transfers)
    • +
+ + + + + 5. Fees and Exchange Rates + +

Our fees are transparently displayed before you confirm any transaction. Fees vary by corridor, payment rail, and transfer amount. Exchange rates are provided in real-time and may fluctuate between quote and execution unless you use our Rate Lock feature.

+

We reserve the right to modify our fee structure with 30 days' notice to users.

+ + + + + 6. Anti-Money Laundering and Compliance + +

    • +
  • EU Anti-Money Laundering Directives
    • +
  • FATF Recommendations and Travel Rule requirements
    • +
+

We automatically file Currency Transaction Reports (CTR), Suspicious Activity Reports (SAR), and other regulatory reports as required. Transactions may be delayed, frozen, or declined for compliance reasons.

+ + + + + 7. Prohibited Activities + +

You may not use the Platform for:

+
    +
  • Money laundering, terrorist financing, or other illegal activities

    • +
  • Any activity that violates applicable laws or regulations
    • +
+ + + + + 8. Limitation of Liability + +

To the maximum extent permitted by law, RemitFlow shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the Platform. Our total liability shall not exceed the fees paid by you in the 12 months preceding the claim.

+

We are not liable for delays or failures caused by payment rail providers, banking partners, regulatory actions, or force majeure events.

+ + + + + 9. Governing Law and Dispute Resolution + +

These Terms are governed by the laws of England and Wales. Any disputes shall be resolved through binding arbitration administered by the London Court of International Arbitration (LCIA), except where prohibited by local consumer protection laws.

+

For users in Nigeria, disputes may alternatively be resolved through the CBN Consumer Protection Framework. For users in the EU, you retain the right to bring proceedings in your local courts.

<158243242+devin-ai-integration[bot]@users.noreply.github.com> Date: Sat, 20 Jun 2026 17:10:16 +0000 Subject: [PATCH 14/17] feat: add performance tuning for Fluvio, open-appsec, OpenSearch, Lakehouse, MySQL (Mojaloop) - MySQL 8.0 tuning for Mojaloop central-ledger: InnoDB buffer pool 180GB, 16 instances, redo log 16GB, 20K IOPS, 16 read/write I/O threads, GTID replication, ROW/MINIMAL binlog - Fluvio streaming: 3-SPU cluster, 24/12/6 partition tiers, lz4 compression, 1MB batches, 5ms linger, replication factor 2 - open-appsec WAF: async prevent mode, 5ms inspection timeout, 10K concurrent inspections, ML batch inference (64 records), bypass rules for static/health, trusted internal CIDRs - OpenSearch: 3-node cluster, 16GB JVM heap, G1GC optimized, 12/6/3 shard tiers, async translog, bulk API (5K actions), 20% query/index cache, mmapfs storage, lz4 transport - Lakehouse ETL: asyncpg pool 10-50, 100K batch size, zstd Parquet compression, DuckDB 16 threads/32GB, 128MB row groups, Iceberg auto-compaction, Z-order optimization Code changes: - Rust Fluvio service: connection pool 100 idle/host, TCP keepalive, HTTP/2 adaptive window, TCP_NODELAY - Python OpenSearch service: persistent httpx client with 200 max connections, HTTP/2, bulk index API - Python Lakehouse ETL: env-configurable pool (10-50), 50K query recycle, 120s command timeout - TypeScript WAF middleware: inspection timeout 200ms -> 5ms (env-configurable via OPENAPPSEC_INSPECTION_TIMEOUT_MS) K8s manifests: - OpenSearch StatefulSet: 3 replicas, 32Gi memory, 500Gi NVMe, pod anti-affinity, sysctl init container, Prometheus annotations - MySQL StatefulSet: 3 replicas, 32Gi memory, 200Gi NVMe, perf ConfigMap mount, mysqld-exporter sidecar Docker Compose perf overrides: MySQL, OpenSearch, Fluvio, open-appsec, Lakehouse ETL with resource limits and env tuning Co-Authored-By: Patrick Munis --- infra/perf/docker-compose.perf.yml | 131 ++++++++++++ infra/perf/fluvio-config.yaml | 135 +++++++++++++

Content-Transfer-Encoding: 8bit - Gap 1: Agent-to-transfer linking — cashPickup.assignAgent assigns specific agent location to cash_pickup transfers, notifies sender with pickup details - Gap 2: Pickup code verification — SHA-256 hashed 6-digit codes with 5-attempt lockout, 72hr expiry, code regeneration support - Gap 3: Agent location finder — cashPickup.findAgents queries agent_network by country/city/currency with pagination - Gap 4: Float replenishment — requestTopUp/approveTopUp workflow with admin verification, floatStatus with low-balance alerts (20% threshold) Also fixes: - transfer-state-machine: cash_pickup transfers no longer route to external payment rails — funds stay on-platform until agent disburses - transferEngine: cash_pickup payout method maps to 'cash_pickup' rail (was incorrectly mapped to 'bank_transfer') - transfer.send: stores deliveryMethod in transaction channel + metadata - SSE events: 4 new event types for cash pickup lifecycle New files: -
