The Flow

Up and running in 3 steps

1

Create a payment link

Set up your product in the console. Name it, set the amount, choose your settlement wallet — done in seconds.

2

Customer pays with supported tokens

Your customer connects their wallet or pays with a card. Routing moves supported assets into your chosen settlement path on Base.

3

Funds arrive in your wallet

Settlement lands on-chain in ~2 seconds. A signed webhook fires immediately so your backend can fulfil the order.

Why Coal

Everything you need, nothing you don't

Non-custodial

Funds flow directly to your wallet. Coal never holds them — no escrow, no counterparty risk, no waiting.

Flexible token routing

Route supported ERC-20 payments into your preferred settlement asset on Base without forcing a custom payment flow.

Pay with card

MoonPay on-ramp is built in. Customers who don't have crypto can still pay with Visa or Mastercard.

Webhook events

Every payment fires a signed webhook so your backend can fulfil orders, update databases, or trigger workflows in real time.

Revenue splits

Configure automatic multi-party payouts once. Funds split instantly between platform, creator, partner, and DAO.

x402 Paywalls

Gate any HTTP resource with a single response header. Charge per-request without building a full checkout flow.

Pricing

Stripe charges 2.9%.
Coal doesn't.

No transaction fees. Ever. You only pay gas — less than $0.01 per payment on Base.
