Implementation
Built into your stack.
Unter plugs into the payment flow you already run. You create a payment request, the customer pays in a checkout under your brand, and stablecoins settle in wallets you own. We scope the integration with you in weeks and build it together with your team.
- Scoped in weeks
- Built with your team
- Tested before you go live
- MCP-ready
USDCThree things to connect.
Your stack stays as it is. Unter sits between your payment request and the stablecoins in your wallets, and handles the crypto in between.
-
01
You create a payment request.
Your system says what you want to receive: the amount, the stablecoin and chain to settle in, and your own references. Only you see and set the settlement.
-
02
The customer pays under your brand.
The customer picks crypto in your checkout and the payment opens under your brand. Every route is checked before it is shown.
-
03
Your systems hear back.
A webhook for every completed payment and every settlement, so your back office updates itself. Payouts run through your own systems.
Settlement on your rules.
- A wallet per chain, set up for youUnter sets up a settlement wallet on each chain you use. They are yours.
- Consolidate when you wantBy hand, on a schedule, or when a wallet reaches a balance you set.
- Prepared by Unter, signed by youUnter prepares the sweep. You approve and sign it, so Unter never holds the funds.
- Into the asset and chain you chooseKeep funds per chain, or consolidate to one stablecoin on one chain.
- Paid out your wayThrough your PSP, or through your own integration with Unter.

Questions your team will ask.
The short answers, by topic. Anything else, ask us directly at team@unter.tech.
What do we need to build?
Three things: a way to create a payment request from your system, a crypto option in your checkout that opens the payment under your brand, and an endpoint that receives our webhooks. We scope the details with you.
How long does an integration take?
Integrations are scoped in weeks. We do the integration work together with your team.
Can we test before we go live?
Yes. You test the full flow, from the payment request to the stablecoins in your wallets, before you go live.
Can our AI tools work with Unter?
Yes, through MCP. Your team and your own agents can look up payments, transaction history, balances, settlement status and error codes, create payment intents, prepare refunds and request settlement quotes. Settlements and refunds run only once you have approved them.
Does the customer leave our checkout?
They choose crypto in your checkout and pay in a checkout under your brand, with your name and your colours. Unter stays out of sight.
Who sets up the settlement wallets?
Unter sets up a settlement wallet on each chain you use. They are yours, and every sweep is signed by you.
Does Unter ever hold our funds?
No. Unter is non-custodial. Payments settle straight into your wallets, and Unter never holds the funds.
Which stablecoin do we receive?
An approved stablecoin, usually USDT or USDC, on the chain the customer paid on. Consolidate later to the asset and chain you choose.
How do our merchants get paid?
Payouts run through you, the PSP. Fiat goes through a licensed off-ramp that you contract yourself.
What do we keep for each payment?
A record for every payment: the customer wallet screened before signature, the route checked before it was shown, what was paid, what arrived and where it settled.
Are customer wallets screened?
Yes. Every customer wallet is screened before the customer signs.
What happens when a route cannot complete?
It is not offered. Before the customer sees a way to pay, Unter checks the wallet, network, balance, fees and liquidity, and holds back what would fail with a plain-language reason.
