The industry-standard verification layer trusted by over 2.4 million wallet holders worldwide. Protect your assets against exploits, phishing attacks, and unauthorized access through our cryptographic verification system — without ever exposing your private key.
CryptoShield is a cryptographic wallet verification protocol that enables non-custodial wallet holders to prove ownership of their wallet address and receive an on-chain verification certificate — without ever handing over control of their assets.
Unlike custodial verification services that require you to send funds to prove ownership, CryptoShield uses WalletConnect v2 and ECDSA signature verification — the same cryptographic primitive used by Ethereum and Bitcoin — to authenticate wallet control through a simple message signing step.
The resulting certificate is recorded on a public blockchain and queryable via our API, giving dApps, DAOs, NFT platforms, and DeFi protocols a reliable, tamper-proof way to check whether a wallet address has been verified.

Verification uses only a signed message — no gas fees, no on-chain transactions.
Trust Wallet, MetaMask, Phantom, Coinbase Wallet, Ledger Live, and more.
Certificate issued within seconds and permanently anchored to the blockchain.
Disconnect the session and revoke the certificate instantly from your wallet settings.
Smart contracts reviewed by CertiK, Hacken, and Quantstamp with public reports.
The entire verification flow is automated and completes in under 60 seconds — from wallet selection to certificate issuance.
Choose your wallet provider from the supported list. CryptoShield currently supports Trust Wallet, MetaMask, Coinbase Wallet, Phantom, Ledger Live, and any WalletConnect v2 compatible wallet. The correct connection standard is automatically detected for each provider.
Approve a read-only WalletConnect session directly in your wallet app. This grants CryptoShield access only to your public wallet address. No transaction permissions are granted and no funds can be moved under any circumstances.
After a cryptographic ownership check, your certificate is issued and recorded on-chain. The certificate includes a unique ID, timestamp, wallet type, and active status — all verifiable independently via our public API.
The Web3 ecosystem is growing — and so are the threats. Wallet verification is becoming a baseline requirement across DeFi, NFTs, and DAOs.
Scammers frequently impersonate wallet addresses in NFT drops, airdrops, and DAO governance. A CryptoShield certificate creates a publicly checkable proof of identity tied to your address — making impersonation detectable.
Many DAOs require verified wallet addresses to participate in governance votes, preventing Sybil attacks where one entity controls multiple wallets. CryptoShield verification is accepted by over 40 DAO governance frameworks.
NFT projects use CryptoShield to validate wallet allowlists before mint windows, ensuring that spots go to real, verified wallet holders rather than bot-operated addresses trying to exploit minting mechanics.
Regulated DeFi platforms operating under AML frameworks use wallet verification as part of their compliance workflow. CryptoShield provides the cryptographic ownership proof needed without requiring KYC-grade personal identification.
Your CryptoShield certificate travels with your wallet address. Any dApp, marketplace, or platform that queries our public verification API can display your verified status — no re-verification required.
If your wallet is compromised and you recover it to a new address, re-verification through CryptoShield re-establishes a clean, fresh ownership certificate — providing a documented continuity trail recognized by supported platforms.
CryptoShield uses no proprietary technology. Every component is built on open, audited, and battle-tested standards from the Web3 ecosystem.
Industry-standard open protocol for secure dApp-to-wallet connections. End-to-end encrypted relay.
Sign-In With Ethereum standard for human-readable, wallet-displayed message signing.
Immutable smart contract registry deployed on a public L1 blockchain. Zero trust required.
Bank-grade encryption on all HTTP traffic between client and verification server.
As of April 2024, over 2.4 million unique wallet addresses have been verified through the CryptoShield protocol across all supported networks.
Ethereum, BNB Chain, Tron, Solana, Bitcoin, Polygon, Arbitrum, Optimism, Base, and Avalanche are all supported for verification.
Trust Wallet, MetaMask, Coinbase Wallet, Phantom, and Ledger Live are fully integrated. Exodus integration is in active development.
