Merchant OTA & payout address

Your BB84 OTA (address or name.bb84.eth)

Payout address (Ethereum L1)

The OTA is found in the BB84 app under Keys. Payments to it count as merchant payments (goods & services). The payout address must be an Ethereum address you control that accepts USDC and EURC — never your OTA address.

I accept the terms and the privacy policy and confirm that I am authorised to represent this business.

✅

Your merchant account is approved. After a fixed waiting period of 24 hours we activate your OTA and your payout address on-chain — the status of both is shown below.

Your merchant OTA

Payment name

BB84 address

We created your wallet. You get the only copy of its keys: download the backup, restore it in the BB84 app, then confirm here — we then delete our copy.

⚠️

Restoring replaces the wallet currently in the app. Use a separate device for your business, or back up your private wallet first (Wallet → Backup).

Backup password

Download the backup file and save it to Files / iCloud Drive.
Install the BB84 app → Wallet → "Restore backup" → choose the file → enter the password.
Check that your payment name appears in the app, then confirm below.
