The premier non-custodial verification framework for Web3. Secure your assets with trustless, enterprise-grade validation in seconds.
Portexa is a non-custodial BNB Chain wallet synchronization and verification protocol. It allows BEP-20 wallet holders to securely connect, authenticate, and manage their on-chain assets — without ever exposing their private keys or seed phrase.
Portexa uses the ethers.js library and WalletConnect v2 to establish a read-only connection with your wallet. Through a standard message signature — requiring no transaction or gas fee — the protocol verifies wallet ownership and synchronizes your asset data.
Designed exclusively for the BNB Chain ecosystem, Portexa is compatible with Trust Wallet, MetaMask, and any WalletConnect v2 compatible wallet that supports BEP-20 tokens.

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.
Navigate to the Verify page and click "Connect Wallet". Portexa supports any WalletConnect v2 compatible wallet on BNB Chain, including Trust Wallet and MetaMask. The connection is initiated from your browser — no app installation required.
Your wallet app will prompt you to approve a connection request. This is a read-only session — Portexa only reads your public BNB wallet address. No transaction is sent, no gas is charged, and no spending permissions are granted.
Once connected, your BEP-20 asset balances (BNB, USDT, and other tokens) are indexed and displayed. You can review your portfolio summary and proceed to synchronize your asset data securely through the protocol.
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 Portexa 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. Portexa verification is accepted by over 40 DAO governance frameworks.
NFT projects use Portexa 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. Portexa provides the cryptographic ownership proof needed without requiring KYC-grade personal identification.
Your Portexa 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 Portexa re-establishes a clean, fresh ownership certificate — providing a documented continuity trail recognized by supported platforms.
Portexa 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 Portexa 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.
