Puffin Pay is the crypto payment gateway by MacLeod Technologies. Your customers pay in stablecoins (USDC, USDT, EURC, USDG, PYUSD and more) on any supported network — Solana, Ethereum, Base, Polygon, BSC, Arbitrum, Optimism or XDC — and you get confirmation webhooks, a dashboard, and receipts.

​
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.
Moving funds between chains once you’re holding them? See Bridging & swaps — native CCTP V2 where it applies, NEAR Intents everywhere else.

​
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.

Pricing

Fees are set by your subscription plan (Starter 1.5%, Growth 1.0%, Scale 0.6%) or a custom rate. See Teams & plans.
