Ask SET a question.

Most things start online: open SET Wallet or start the Payments Platform. For anything else, write here. It does not enter an operator system and cannot authorize a payment or crypto transaction.

SET Merchant API: accounts in your own business's name

You give us

Your business's exact legal name and address
What your business sells and how your payers pay you: by US bank transfer, in USDC, or both
Your own bank account or wallet to be paid into

We deliver

An order form that sets SET's price
Business verification, then your payment details: a US account in your name, a SET Cash-Out Address, or both
An API key and SET's sandbox, if you want to automate

Timeline: SET replies by email with an order form. Your payment details follow once your business passes verification.

Price: Set in your order form. SET's fee is withheld as each payment settles, or invoiced monthly, as the order form sets.

Arrange repository or deployment access through a separately approved secure channel, never this form. Submitting an inquiry does not reserve delivery time; work begins only after a written agreement and authenticated payment evidence.
