Developer

Self-Hosting

Run Auron locally or deploy to Vercel. The whole app — including these docs, at /docs — lives in one Next.js project at apps/web.

Local setup

bash

git clone https://github.com/anirudhh206/auron
cd auron/apps/web
npm install
cp .env.example .env.local
npm run dev

The dev server starts at http://localhost:3000. With only the required env vars set, the app runs in demo mode — on-chain verification still runs against devnet, but the final INR payout is simulated.

Database setup

Auron uses Supabase (Postgres). Run the migrations in order in the Supabase SQL Editor:

bash

# Initial schema — transactions, settlements, status_history, users, kyc_submissions, contacts, intent_log
apps/web/lib/db/schema.sql

# Migration 001 — receipt hash + refund columns
apps/web/lib/db/migration_001_receipt_refund.sql

# Migration 002 — api_keys table (AI agent authentication + daily spend caps)
apps/web/lib/db/migration_002_api_keys.sql

# Migration 003 — demo UTR cleanup
apps/web/lib/db/migration_003_demo_utr_cleanup.sql

WARNING

Row-level security is enabled on all tables by default. Make sure you are using the service role key (SUPABASE_SERVICE_ROLE_KEY) in server-side routes — the anon key will fail most write operations.

Environment variables

Required — basic functionality

ANTHROPIC_API_KEYREQ

Claude AI for intent parsing and chat. Get at console.anthropic.com.

NEXT_PUBLIC_SUPABASE_URLREQ

Your Supabase project URL.

NEXT_PUBLIC_SUPABASE_ANON_KEYREQ

Supabase anon key — safe for client-side use.

SUPABASE_SERVICE_ROLE_KEYREQ

Service role key — server-side only. Never expose to client.

NEXT_PUBLIC_SOLANA_NETWORKSet to devnet for development, mainnet-beta for production.

Required — real settlements

RAZORPAY_KEY_IDREQ

Razorpay API key ID. Use rzp_test_xxx for sandbox.

RAZORPAY_KEY_SECRETREQ

Razorpay API secret. Server-side only.

RAZORPAY_ACCOUNT_ID

Razorpay X virtual account number. Required for real UPI payouts. Needs KYB.

ONMETA_API_KEY

OnMeta off-ramp API key. Primary settlement path. Requires OnMeta KYB (3–7 days).

ONMETA_WEBHOOK_SECRET

HMAC secret for OnMeta webhook verification. Without this, webhooks are unverified.

TREASURY_KEYPAIR_BASE58Base58 private key of the treasury wallet. Required for auto-refunds. Never log or expose.

Infrastructure

KV_URL

Vercel KV connection URL. Required for rate limiting. Degrades gracefully without it.

KV_REST_API_URL

Vercel KV REST API URL.

KV_REST_API_TOKEN

Vercel KV REST token.

SOLANA_RPC_URL

Helius or custom RPC. Defaults to public devnet if unset (slow).

CRON_SECRETBearer token for /api/workers/*. Without this, settlement and reconciliation workers are publicly callable.

Monitoring & security

SENTRY_DSN

Sentry project DSN for error tracking.

NEXT_PUBLIC_SENTRY_DSN

Client-side Sentry DSN.

NEXTAUTH_SECRETSession signing secret. Generate with: openssl rand -hex 32

Feature flags

DEMO_SETTLEMENT

Set true to skip real payout dispatch. On-chain verification still runs.

NEXT_PUBLIC_FULL_DEMO_MODE

Set true to skip on-chain TX entirely. For demos without Phantom.

NEXT_PUBLIC_ENABLE_VOICE_INPUTSet true to enable Web Speech API voice input in the chat interface (Chrome only).

Vercel deployment

bash

cd apps/web
vercel --prod

Configure Vercel Cron in apps/web/vercel.json for the settlement and reconciliation workers:

apps/web/vercel.json

{
  "crons": [
    {
      "path": "/api/workers/settlement",
      "schedule": "0 0 * * *"
    },
    {
      "path": "/api/workers/reconcile",
      "schedule": "0 2 * * *"
    }
  ]
}

NOTE

Vercel Hobby plan only allows daily cron granularity, so both workers run once a day (settlement at 00:00 UTC, reconciliation at 02:00 UTC). If you're on a Pro plan or self-hosting the cron trigger, you can run the settlement worker far more frequently — the route itself has no rate limit beyond CRON_SECRET auth.

Live activation — OnMeta

OnMeta is a FIU-registered crypto off-ramp under India's VDA framework. KYB is required for production settlements.

Apply at onmeta.in/business

Submit: Certificate of Incorporation, Director Aadhaar + PAN, bank account proof

Compliance review

3–7 business days for KYB approval

Set ONMETA_API_KEY + ONMETA_WEBHOOK_SECRET

Add to Vercel environment variables

Set https://your-domain.com/api/webhooks/onmeta in OnMeta dashboard
