Arbitrum checkout with full stablecoin support.
Arbitrum One is one of the most liquid Ethereum L2s, with cheap fees and deep stablecoin support. My Crypto Server accepts ETH plus USDC, USDT, and DAI on Arbitrum and settles every payment straight to your wallet.
Same Ethereum assets, a fraction of the gas. Customers pay stablecoins cheaply while you keep the full order amount with no platform cut.
Native ETH plus USDC, USDT, and DAI on Arbitrum One.
How it works
Clone the repo, push it to Vercel, attach any Postgres database, and add your Alchemy API key. You're live in about an hour with no approval or underwriting to wait on.
Add the extended public key from a wallet you control. Every Arbitrum payment address the checkout shows is derived from your own seed, so funds are always yours.
Price the order in USD from the dashboard, the REST API, or the TypeScript SDK. The hosted checkout shows the customer a live Arbitrum amount, a QR code, and a countdown.
The customer pays from any wallet, the server confirms on-chain, and a signed webhook hits your backend so fulfilment fires automatically.
No 2.9% + 30¢, no monthly minimum, no reserve. The only cost is network gas, which the customer pays, so the full order amount lands in your wallet.
Every payment address derives from a seed only you hold and settles directly to you. There's no custodian, no payout schedule, and no balance anyone can hold.
Stablecoin amounts are matched to the order's dollar price, so a $200 order is exactly $200 with no volatility to manage and no exchange in the loop.
Full source, self-hosted on Vercel + Alchemy in under an hour. No vendor can raise fees, change terms, or sunset the checkout your store depends on.
Native ETH plus USDC, USDT, and DAI, all detected per address and settling to your own wallet.
