Proof of Control

One API to verify control of any digital asset — phones, emails, domains, social accounts, and crypto wallets.

30+ verification channels. Cryptographic proof tokens. 90% lower cost than SMS OTP.

How It Works

Same flow for every asset type — one integration covers all channels

01

One API Call

Create a verification request with the asset type, channel, and identifier. Same endpoint for all 30+ channels.

02

User Proves Control

User completes the challenge: send a message, click a link, sign a transaction, or authorize via OAuth.

03

Cryptographic Proof

Receive a signed RS256 JWT proof token. Verify offline — no API calls needed after issuance.
