SmartHoldem Wallet (STH)

Self-custodial wallet for the SmartHoldem (STH) blockchain: send, receive, swap and sign for dApps. Your keys, your coins.

SmartHoldem Wallet is the official self-custodial browser wallet for the SmartHoldem (STH) blockchain. Manage STH, connect to SmartHoldem dApps and sign transactions - without ever handing your private keys to anyone. WHY SMARTHOLDEM WALLET • Self-custody by design - keys are generated and encrypted on your device only. No accounts, no KYC, no cloud, no tracking. • Side Panel UI - the wallet docks next to any page, so you can keep playing or trading while you sign. • Built for the SmartHoldem ecosystem - native STH transfers, memo (vendor field) support, fixed network fee shown upfront. CORE FEATURES • HD multi-account: unlimited deterministic sub-accounts from one BIP-39 seed; switch accounts in one tap. • Send & Receive: address validation, QR code receive dock, live balance and transaction history. • Swap Hub: STH ↔ USDT (BEP-20) through the official SmartHoldem exchange gateway, directly inside the wallet. • Web3 provider: injects window.smartholdem so dApps can request a connection, ask you to sign a message or approve a transaction - every request is shown to you first and can be rejected. • Connected Sites manager: see and revoke every dApp you have authorised. • Address book, 3 visual themes (Rust Classic, Cyan Steel, Industrial Light), 4 languages (EN / RU / ZH / ES). SECURITY • AES-256-GCM encrypted vault, PIN unlock, configurable auto-lock timer. • Encrypted backup export/import (.sth) - restore on any device. • 100 % of code ships inside the extension; no remote scripts, no analytics, no telemetry. • Manifest V3, strict Content-Security-Policy, open source: https://github.com/smartholdem/core-wallet FOR DAPP DEVELOPERS Integrate in minutes: await window.smartholdem.connect(); window.smartholdem.signMessage(msg); window.smartholdem.sendTransaction(tx).
