Payments on Optimism
Accept USDC payments on Optimism
Accept USDC, USDT, DAI, or ETH on the Optimism network — an Ethereum rollup with low transfer costs, settling wallet to wallet.
Accepts USDC, native ETH, USDT, DAI on Optimism. Settle never holds funds — payments settle straight to your wallet.
HOW IT WORKS
Three steps.
No custody.
Everything runs on your wallet. Settle is the checkout, the verification, and the record-keeping — never the money.
02
Share a checkout
Create a payment link, invoice, or product page at a dollar price. Customers see a hosted checkout with your branding.
03
Get verified payments
Transfers settle directly into your wallet. Settle verifies each one on-chain before marking it paid, then issues the receipt.
Why accept payments on Optimism
Optimism is one of the longest-running Ethereum rollups and a common home for USDC. For customers whose funds live there, an Optimism checkout means paying in seconds without bridging — and for you, it costs the same as your other rollup options: 0% platform fee during launch, plus cents of network fee.
It completes the set of major Ethereum rollups: enable Base, Arbitrum, and Optimism together and an Ethereum-ecosystem customer can almost always pay you from wherever their USDC already sits.
Fees and costs, plainly
Optimism is an Ethereum rollup, so stablecoin transfers typically cost a few cents or less — a fraction of mainnet fees. That network fee is paid by your customer when they send the payment, and it goes to the network — not to Settle.
Settle's platform fee is 0% during launch on every network, so the cost of a payment is the network fee and nothing else. If pricing ever changes, it will be announced in advance and published on the pricing page before it takes effect.
Wallets your customers will use
Any EVM wallet: MetaMask, Coinbase Wallet, Rainbow, Rabby, and others — connect in the browser or scan the QR code. No account creation is required to pay — a customer opens your checkout, approves the exact amount, and they're done.
You can collect an email for the receipt, make it optional, or allow fully anonymous checkouts — the choice is yours, per link or product.
How Settle verifies the payment
On Optimism, Settle reads the token contract's transfer record on the blockchain and checks that the exact amount, of the right token, arrived at your wallet. A transaction hash by itself settles nothing — the transfer itself has to be on-chain and match.
Once verified, the payment is marked complete, your customer receives a receipt by email, and your dashboard shows the full timeline — detection, verification, and settlement — alongside the transaction on the block explorer.
