Automatic matching
Every USDC/USDT transfer connected to the right customer and invoice — across Arbitrum, Base, Ethereum, HyperEVM, Optimism, Solana, and Tron.
Founding pilot
Bring the wallet.
Leave with clean books.
A hands-on 60-day pilot for businesses already getting paid in USDC or USDT. We map your wallets, import your invoices, reconcile your last 90 days, and run a real month-end close with you.
The problem
The transfer happened.
Now, what was it for?
Your customers pay you in stablecoins. The money arrives — but your wallet and a block explorer can't tell you who paid, which invoice it settled, whether it was short or duplicated, or what your accountant needs at month-end. So someone pieces it together by hand, every month.
MainPay connects that last mile — without ever touching your funds.
What MainPay does
Every payment accounted for.
Exception workbench
Catch short, over, late, duplicate, unknown, and wrong-token payments before they reach your books — resolved in a click.
Audit-ready month-end
Export exact amounts, addresses, transaction hashes, timestamps, and reconciliation status as accountant-ready CSVs for QuickBooks, Xero, or your accountant.
Designed around control
Your money never
touches MainPay.
MainPay is non-custodial. Customers pay the receiving addresses you control; funds settle directly to your wallet. We only ever need a public address to monitor payments — never a private key, seed phrase, or custody of funds.
Every record links back to its source transaction on-chain.
What the pilot includes
You don't set this up alone.
Concierge onboarding
We map your wallets, import your recent invoices, and set your exception rules with you — with a weekly line straight to the founders.
A 90-day head start
We reconcile your last 90 days of on-chain payments, so you begin with organized books instead of an empty screen.
A live month-end close
We run MainPay alongside your team through at least one real close and hand your accountant the export.
What we ask of you
- You already receive stablecoin payments — roughly 20+ a month — and reconcile them by hand today.
- Share your public receiving wallet(s) and a CSV of recent invoices so we can show you real results.
- About 30 minutes a week during the pilot, and honest feedback on what works.
Simple terms
- 60-day pilot, free or symbolic while you evaluate it.
- Continue at $29/month — the Starter plan — only after your first successful close.
- No lock-in, no custody, cancel anytime. Your data is yours — export everything, whenever you want.
