How to verify a crypto payment on-chain
Before you hand over a file or a license key, you want to be sure the USDT, USDC or BTC actually arrived — in the right token, the right amount, to your own wallet, and confirmed. Here's how to check it yourself on a public block explorer. And if you'd rather not do it by hand on every sale, StableDeliver does exactly this automatically and delivers the moment the payment confirms.
Find the transaction
Take the transaction hash the buyer paid with and open the public block explorer for that chain (links below). It's read-only — you're just looking up a transaction.
Check the details
Confirm the destination is your own wallet address, the token is the one you asked for (USDT / USDC / BTC), and the amount matches. A payment to the wrong address or in the wrong token is not your payment.
Confirm it's settled
Make sure the transaction is mined and has enough confirmations — a pending or failed transaction can be reversed. Only then is the money really yours.
Doing this on every sale is slow — automate it
StableDeliver runs these exact checks for you: it confirms the exact transfer to your wallet on-chain, then delivers the file, link or license key automatically the second it's verified. Non-custodial — the money still goes straight to your own wallet.
Block explorers
Use the public, read-only explorer for the chain the buyer paid on. Paste the transaction hash to confirm the details yourself.

FAQ
Why verify on-chain at all?
A screenshot or a 'paid' message proves nothing — it's trivial to fake. The blockchain is the source of truth: the transaction either exists, went to your address, in the right token and amount, and confirmed — or it didn't.
Is StableDeliver non-custodial?
Yes. Funds go straight from the buyer to your own wallet — money never touches StableDeliver, and we never have your private keys or seed phrase. We verify the on-chain payment and deliver your product; we never hold or move funds.
Which chains?
Supported chains today are Ethereum, Polygon, BNB Smart Chain, Arbitrum, Solana, Tron, Bitcoin. USDT and USDC are supported where available on each chain; BTC on Bitcoin.
