Prove wallet control — without a transaction

This page connects a wallet, anchors a challenge to a live Base block, asks the wallet to sign that exact message, and verifies the signature.

Expected pointer

Network

Base mainnet • chain 8453

ENS pointer

jaywisdom.base.eth — pointer only

Repository

jsonwisdom/COMPUTERWISDOM

ENS ≠ CONTROL • SIGNATURE ≠ HUMAN IDENTITY • CONTROL ≠ AUTHORITY • NO TRANSACTION

PROVIDER: NONE WALLET: NOT CONNECTED CHAIN: UNKNOWN POINTER: NOT CHECKED CONTROL: NOT VERIFIED

Choose Coinbase Wallet first if that is the smart wallet you want to prove. MetaMask/browser injection is a separate fallback.

I understand this requests a message signature only. It does not send ETH, trade, transfer, create an ENS record, create an EAS attestation, or grant authority.
