Accept payments · ETH

Accept Ethereum payments.

Invoice in the currency you sell in, and let your customer pay in Ethereum. We give the invoice a keyless address on the chain they choose, watch it, and send you a signed webhook when the payment is final. Native gas on Ethereum and on every rollup we support, which is why one ETH page covers seven chains.

Start building How accept payments works

ETH on 7 chains.

Your customer picks one at checkout. You choose which of them you are willing to accept.

ETH on Ethereum: Gas here is the highest of any chain on this list, so a payment has to clear a minimum amount to be worth collecting. The checkout shows that minimum to your payer before they choose Ethereum, and every other chain here is cheaper.
ETH on Scroll: The USDC on Scroll is the bridged token, because Circle does not issue natively here. It spends the same way; the contract address is just not Circle's own.

Taking a Ethereum payment.

Create the invoice

One POST with an amount, a pricing currency and your own reference. You get back a checkout URL, one payment address per chain, and a locked amount in every coin you accept.

They pay, at a rate that stays honest

Your customer is never asked to commit to a chain first — one address serves every EVM chain, so whatever arrives is attributable. Stablecoins are quoted once. A volatile coin is re-quoted every two minutes, and the figure it replaces is still honoured for five, so nobody who did as they were told is told they underpaid.

You get a signed webhook

HMAC-SHA256, retried for about 46 hours, replayable from the dashboard. The payment is credited to your balance per asset.

POST /v1/invoices

curl https://api.molnpay.com/v1/invoices \
  -H "Authorization: Bearer $MOLNPAY_SECRET_KEY" \
  -H "Idempotency-Key: order_8812" \
  -d amount="49.90" \
  -d currency="USD" \
  -d reference_id="order_8812"

What you do not have to do.

Hold a ETH wallet, or guard a seed phrase for one. Every address is a contract with no key.
Keep gas on hand. Our operator wallet funds the sweep on every chain ETH settles on.
Ask your customer to make an account. The hosted checkout needs nothing from them but a payment.
Run a watcher that must never miss a block, or reconcile a reorg by hand.

Holding ETH for your users instead?

Same API, same keys, same balance — the difference is whether the address belongs to an invoice or to one of your users.
