Overview
Multi-chain crypto wallet with voice-call approval. Send ETH, BNB, SOL, USDC, USDT — works even when offline.
OffChain is a multi-chain crypto wallet built around one idea: you should be able to send crypto even when your phone has no internet. KEY FEATURES • Native Solana support — SOL + every SPL token (USDC, USDT) • Multi-chain — Ethereum, BSC, Arbitrum, Bitcoin, TON • AI agent — type "send 0.5 SOL to alice.sol" or "trending tokens" • USDC checkout on Amazon and eBay • Same account syncs with the OffChain mobile app + SMS bot THREE WAYS TO APPROVE A TRANSACTION 1. PIN in browser — fastest, backend verifies your PIN 2. Voice-call approval — backend calls your phone; press 1 to approve. Works in every country. 3. Text from your phone — when your browser has no internet, the extension generates a QR you scan with your phone to send the transaction over cellular SMS. ABOUT KEY CUSTODY OffChain uses a hybrid-custody model. Your encrypted private keys are stored on our backend so transactions can be authorized by voice call or SMS when your browser has no internet. Keys are PIN-gated server- side, never logged in plaintext, and you can revoke them at any time from Settings.
