From 67fbf9dfe8cdd96b12341b5711a2082425a65601 Mon Sep 17 00:00:00 2001 From: driftsorbit Date: Wed, 27 May 2026 13:04:11 +0000 Subject: [PATCH] feat(kyc): validate provider config at boot and expose readiness - Add KYC_PROVIDER_URL, KYC_PROVIDER_API_KEY, KYC_PROVIDER_SECRET to the central Zod schema in src/config/index.js; superRefine rejects partial config (URL without key or key without URL) in non-test envs - Update getKycProviderConfig() in kycService.js to read from the validated config module instead of process.env directly - Add checkKycHealth() to health.js: skips when disabled, probes the provider URL via HEAD with Authorization header (key never leaked in response); wire into performHealthChecks() so /ready returns 503 when the provider is unreachable - Document KYC vars in .env.example with pairing requirement - Add tests/kyc.gating.test.js: 15 tests covering valid config, partial- config rejection, disabled passthrough, and degraded /ready state Closes #213 --- .env.example | 18 + package.json | 1 - src/config/index.js | 38 +- src/services/health.js | 54 ++- src/services/kycService.js | 22 +- tests/kyc.gating.test.js | 707 ++++++++----------------------------- 6 files changed, 265 insertions(+), 575 deletions(-) diff --git a/.env.example b/.env.example index c34f8316..0193b110 100644 --- a/.env.example +++ b/.env.example @@ -161,3 +161,21 @@ ESCROW_INDEXER_ENABLED=false ESCROW_INDEXER_POLL_INTERVAL_MS=15000 ESCROW_INDEXER_BATCH_SIZE=100 STELLAR_HORIZON_URL=https://horizon-testnet.stellar.org + +# ------------------------- +# KYC Provider Config | +# ------------------------- +# External KYC provider integration.
