EVM Compatible
BNB Chain Verification
Verify BNB Chain wallet control through message signing. EVM-compatible verification works with Trust Wallet, MetaMask, and all BSC wallets.
How It Works
Standard EIP-191 message signing verification
Step 1
Create Challenge
Call our API with the BNB Chain address. We generate a unique message for the user to sign.
Step 2
User Signs Message
User signs the challenge message with their wallet (Trust Wallet, MetaMask, etc.). No transaction needed.
Step 3
Proof Generated
We verify the EVM signature and return a proof token confirming wallet control.
