@orderly.network/onramper-plugin

A fiat-to-crypto on-ramp plugin for the Orderly SDK. Adds a "Buy Crypto" tab to the Transfer dialog, allowing users to purchase USDC with fiat currencies through Onramper.

Features

Fiat-to-Crypto Purchases

Buy USDC directly within the Orderly trading interface. Users enter a spend amount in fiat, choose a payment method and on-ramp provider, and complete the purchase through a secure embedded widget.

Multi-Chain Support

Receive USDC on multiple networks including Ethereum, Arbitrum, Base, Optimism, Polygon, Avalanche, zkSync, Solana, BNB Chain, Linea, and more.

Live Quotes & Provider Comparison

Real-time exchange rates from multiple on-ramp providers (Moonpay, Transak, Banxa, etc.), auto-refreshed every 30 seconds. Compare rates side-by-side and pick the best deal.

Payment Methods

Supports multiple payment methods per provider — credit/debit cards, bank transfers, and more. Displays min/max spend limits for each method.

Transaction History

Track on-ramp transaction status (pending, completed, failed) with automatic polling. Requires the optional Cloudflare Worker backend.

Screenshots are available in docs/screenshots/.

Cloudflare Worker Setup (Optional)

A Cloudflare Worker is needed to receive Onramper webhooks and enable transaction history in the plugin. All setup is done through the Cloudflare Dashboard.

1. Create a D1 Database — Go to Workers & Pages → D1 SQL Database, create a new database. Open its console and run the SQL from cloudflare-worker/schema.sql to create the table.

2. Create the Worker — Go to Workers & Pages → Create Worker. Replace the default script with the contents of cloudflare-worker/index.js.

3. Bind the D1 Database — In the Worker's Settings → Bindings, add a D1 Database binding with variable name DB, pointing to the database from step 1.

4. Add the Webhook Secret — In the Worker's Settings → Variables and Secrets, add an encrypted variable named ONRAMPER_WEBHOOK_SECRET with your webhook secret from the Onramper dashboard.

5. Configure Onramper Webhook — In the Onramper Dashboard, set your webhook URL to the deployed Worker URL.

6. Use in Plugin — Pass the Worker URL as workerUrl when registering the plugin.
