Low-fee Base checkout with full stablecoin support.
Base gives your customers Ethereum-grade security with L2 fees, which makes it a natural default for crypto checkout. My Crypto Server accepts ETH plus USDC, USDT, and DAI on Base and settles every payment straight to a wallet you control.
Because Base fees are a few cents, customers can pay stablecoins on it without gas eating the transaction, while you keep the full order amount.
Native ETH plus USDC, USDT, and DAI on Base.
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 Base 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 Base 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.
The server watches the chain, waits for reorg-aware confirmations, and fires a signed webhook to your backend the moment a payment clears. No watcher process to babysit.
Native ETH plus the USDC, USDT, and DAI stablecoins, all detected per address and settling to your own wallet.
Base offers the same assets at a fraction of the gas cost, so paying a small stablecoin invoice is economical for the customer. You can offer both and let them choose.
Yes. USDC, USDT, and DAI on Base settle 1:1 against the order's USD price, so there's no volatility to manage.
