BlockWatch Shield

Routes every Web3 signature from any dApp through Telegram for AI review before your real wallet signs.

BlockWatch Shield turns every Web3 signature request from any dApp into a review step inside Telegram. Nothing is signed by your real wallet until you tap Approve in your Mini App chat. How it works 1. Install the extension and pair it with your Telegram in one tap. 2. Browse any dApp normally. 3. When the dApp asks for a signature (transaction, message, permit), the request is paused mid-air. A push lands in your Telegram with: - a plain-language AI explanation of what you are about to sign, - a risk score 0..100 with reasons, - one-tap Approve / Reject buttons. 4. Approve - the request is released back to your wallet to sign. Reject - the dApp gets a clean error. What it catches - ERC-20 unlimited approve and increaseAllowance - ERC-721/1155 setApprovalForAll (NFT drain) - EIP-2612 Permit and EIP-712 typed-data drains - Sign-In with Ethereum vs. hidden approve-in-text tricks - Solana signTransaction / signMessage via Wallet Standard events - TON and NEAR signature requests - ~10,000 known phishing domains from a public eth-phishing-detect list - Punycode and Damerau-Levenshtein lookalikes of legit DeFi sites - Add chain / switch chain / watch asset requests Supported wallets - Any EVM browser wallet that implements the EIP-1193 provider standard - Any Solana wallet that implements the Solana Wallet Standard - Tonkeeper extension on TON - NEAR-compatible browser wallets What it does NOT do - Never sees your private keys, seed phrases, or mnemonics. - Never sends the signature itself - your real wallet does that. - Never touches pages that do not request a signature. Pre-confirmation security is the only way to stop most drain attacks at the moment they happen, not the moment after. BlockWatch Shield makes it a one-tap experience.
