Deposit addresses · USDT

Tether deposit addresses for your users.

Give every one of your users a permanent Tether address they can deposit to any time. It is computed in advance, it has no private key, and we sweep it and pay the network fee to do so. The most-used settlement asset in crypto payments, and the one most merchants price in.

Start building How deposit addresses works

USDT on 10 chains.

Enable the ones your users need. Each gives that user their own address, and enabling a new one later gives it to the users you already have.

USDT 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.
USDT on BNB Chain: USDT and USDC have 18 decimals on BNB Chain, where they have 6 almost everywhere else. Read decimals from the API rather than writing 6 into your code — getting it wrong is a silent error of twelve orders of magnitude.
USDT on Tron: There is no USDC on Tron — Circle ended its TRC-20 issuance in February 2024. USDT is what everyone uses here in any case, and it is the most common way money moves on this list.
USDT on TON: USDT is the only stablecoin we settle in on TON today. Other jettons can still be received at a deposit address.

Issuing a Tether address.

Create the customer

One POST with your own user id as the reference. This is the record everything else hangs off.

Ask for an address per chain

One per (customer, chain), and it does not change. The address is computed in advance from the customer's salt, so the same customer has the same address on every EVM chain — and you can show it again tomorrow without calling us.

Credit on deposit.confirmed

We watch every block, sweep what lands, and pay the network fee to do it. Sweeps are visible to you and read-only: they never change what you are owed.

POST /v1/customers

curl https://api.molnpay.com/v1/customers \
  -H "Authorization: Bearer $MOLNPAY_SECRET_KEY" \
  -H "Idempotency-Key: user_4471" \
  -d reference_id="user_4471"

What you do not have to do.

Hold a USDT 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 USDT settles on.
Re-issue an address. One per user, per chain, and it does not change.
Run a watcher that must never miss a block, or reconcile a reorg by hand.

Taking USDT payments instead?

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