Optimism checkout with cheap stablecoin settlement.
Optimism gives customers low-fee, fast Ethereum L2 payments with strong stablecoin support. My Crypto Server accepts ETH plus USDC, USDT, and DAI on Optimism, all settling directly to a wallet you control.
Low L2 fees make stablecoin invoices economical, and every payment derives from your own seed and lands straight in your wallet.
Native ETH plus USDC, USDT, and DAI on Optimism.
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 Optimism 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 Optimism 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 USDC, USDT, and DAI, all settling to your own wallet with 0% platform fees.
Yes. Stablecoin payments settle 1:1 against the order's USD price, so there's no volatility to manage.
The server confirms on-chain and fires a signed webhook to your backend, so you can release the order automatically and idempotently.
