D3fenders Wallet (Private Beta)

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 vault-based 2FA transaction protection designed to reduce the risk of unauthorized asset movement after wallet compromise. Unlike traditional wallets that rely solely on a seed phrase, D3fenders allows users to optionally protect sensitive transactions with a second 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 EVM aggregators • Connect to decentralized applications (dApps) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ VAULT-BASED 2FA TRANSACTION PROTECTION ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ D3fenders includes an optional on-chain 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 code. Standard wallet actions such as viewing balances, regular sends, and swaps do not require 2FA. This design helps reduce damage from phishing, wallet drainers, and seed phrase compromise while maintaining usability. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ DAPP CONNECTIVITY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • EIP-1193 compatible Ethereum provider • Solana Wallet Standard support • Connect to decentralized applications • Transaction and message signing • Does not impersonate other wallets ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SECURITY MODEL ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Private keys encrypted locally using AES-256-GCM • Password-derived encryption keys via PBKDF2 • Session-based in-memory encryption • All signing occurs locally in the browser • Private keys are never transmitted over the network • Sensitive data redacted from logs ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • No analytics or tracking • No personal data collection • No data sold or shared with third parties • Wallet data stored locally on the user’s device ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVATE BETA NOTICE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ This is an early access private beta release.
