Self-custody crypto wallet with vault-based 2FA transaction protection. Supports Solana, Ethereum, Polygon, Avalanche, and Arbitrum. D3fenders Wallet is a multi-chain, self-custody browser wallet with optional vault-based 2FA transaction protection designed to reduce the risk of unauthorized asset movement. Unlike traditional wallets that rely solely on a seed phrase, D3fenders allows users to optionally protect selected assets and transactions with an additional authentication factor while retaining full control of their private keys. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SUPPORTED NETWORKS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Solana (Mainnet, Devnet) • Ethereum (Mainnet, Sepolia) • Polygon (Mainnet, Amoy) • Avalanche C-Chain (Mainnet, Fuji) • Arbitrum (Mainnet, Sepolia) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WALLET FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Create new wallets (BIP-39 seed phrase generation) • Import existing seed phrases (12 or 24 words) • Import private keys (Solana base58 or EVM hex) • Multiple accounts per wallet (BIP-44 derivation) • Send and receive tokens (native, SPL, ERC-20) • Send and receive NFTs • View token balances with live USD pricing • Swap tokens via Jupiter (Solana) and supported EVM aggregators • Connect securely to decentralized applications (dApps) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ VAULT-BASED 2FA TRANSACTION PROTECTION ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ D3fenders includes an optional vault system that adds a second layer of protection for selected assets and actions. Vault-protected features include: • Locking tokens and NFTs into a vault contract • Unlocking assets with a one-time password (2FA) • Safe Send workflows for protected transfers • Emergency migration flows with additional safeguards Vault-protected transactions require both a wallet signature and a 2FA verification step. Standard wallet actions such as viewing balances, regular sends, and swaps do not require 2FA. This design adds friction to high-risk actions while maintaining usability for everyday transactions. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ DAPP CONNECTIVITY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • EIP-1193 compatible Ethereum provider • Solana Wallet Standard support • Standards-compliant provider discovery (EIP-6963) • Secure transaction and message signing • Does not override or impersonate other wallets ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SECURITY MODEL ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Private keys encrypted locally using AES-256-GCM • Password-derived encryption keys via PBKDF2 • Session-based in-memory key handling • All signing occurs locally in the browser • Private keys are never transmitted to external servers ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • No analytics or behavioral tracking • No personal data collection • No sale or sharing of user data • Wallet data stored locally on the user’s device D3fenders Wallet operates entirely within your browser. You retain custody of your keys at all times. For security best practices, users are encouraged to test new workflows on supported test networks before interacting with mainnet assets.
