Puffin Pay is MacLeod Technologies’ payment gateway for stablecoins. Give your customers a checkout that accepts USDC, USDT, EURC, and more — on Solana, Ethereum, Base, Polygon, BSC, Arbitrum, Optimism, or XDC — and get a confirmed payment back on your own terms: a signed webhook, a live dashboard, and a receipt your customer can keep. You pick how deep to integrate. Share a link with zero code, drop a checkout modal into your site with one script tag, or drive the whole flow from your server with a single API call — the payment experience is the same hosted checkout page underneath either way.

​
Ways to integrate

Payment links

Zero code. Create a link in the dashboard, share it anywhere.

Hosted checkout

One API call creates a payment; redirect your customer to our checkout page.

Embedded (iframe SDK)

Drop puffin.js into your site and open checkout in a modal — customers never leave.

Wallet-as-a-Service

Need standing wallets rather than one-off payments? Create and manage USDC/USDT wallets across chains directly over the API.
Holding funds across more chains than you’d like? See Bridging & swaps — one endpoint moves value between chains and assets, and we pick the fastest safe route for you automatically.

​
How a payment works

  1. You create a payment intent (amount + token + chain).
  2. Puffin mints a fresh deposit address for that payment.
  3. Your customer pays; we detect and confirm on-chain.
  4. The intent flips to CONFIRMED, your webhook fires (HMAC-signed), and the dashboard updates in real time.
Every payment address is single-use — no amount-matching heuristics, no crossed payments.

​
Getting paid out

Confirmed payments settle to a wallet you control, on the schedule your account is configured for — see Settlement for how that works and how to point it at your own address.

​
Pricing

Fees are set per capability (payments, wallets, bridging) by your plan, with custom rates available as you grow — see Teams & plans for how pricing is structured, or check GET /v1/gateway/merchants/me/fees for your account’s current numbers.
