Welcome

SplitFi is on-chain payment infrastructure for marketplaces. Stripe-style developer experience, USDC settlement, three-tier fee splits.

SplitFi lets you accept USDC on Base and split each payment three ways — to SplitFi, your platform, and your sub-merchants — in a single on-chain transaction.

If you've integrated Stripe Connect, you'll feel at home: sign up → connect a wallet → get an API key → start creating orders.

Quickstart

Make your first test payment in 10 minutes.

Core concepts

The mental model: platforms, merchants, fees, and ledgers.

API reference

Full endpoint reference with request/response shapes.

Hosted Checkout

Send a URL, take payment. No frontend code required.

What you'll build

Platform tenant — your account on SplitFi (think: Stripe's acct_…)
Sub-merchants — the businesses on your platform that receive funds
Orders / payments — created via API, paid by users on-chain
Webhooks — your backend hears about each event in real time
