Sudo Messenger

Read full description

A messenger built for people who actually move onchain. Sudo puts a self-custody wallet, real research tools and a chat app in one place — so you stop switching between six tabs to send someone $20 or check whether a contract is safe. CHAT THAT CARRIES VALUE Send crypto inside a conversation the way you'd send a photo. Split a group payment by custom percentage per member. Paste any contract address and see what it is before you tap send. Share a video link and it plays right in the thread. A WALLET YOU ACTUALLY OWN Self-custody across 16+ networks — Ethereum, Polygon, BNB, Arbitrum, Optimism, Base, Avalanche, zkSync and more. Multiple accounts, import your existing wallet, QR send and receive with network-aware warnings so funds don't land on the wrong chain. Swap and bridge with rates compared across providers and slippage you control. Buy and sell through Alchemy Pay, MoonPay, Transfi and Banxa with card, Apple Pay or Google Pay. AI EXPLORER Ask about a wallet or token in normal language and get an answer, not a dashboard. Where did these funds come from. Why did this token move. Who's holding it. What actually happened in this transaction. It picks the right network on its own, and it tells you when it can't find something instead of making it up. TOOLS THAT CHECK BEFORE YOU TRUST Audit Scan reviews a contract against multiple risk sources — honeypot behaviour, buy and sell tax, mint permissions, hidden ownership. Watcher follows funds hop by hop across a chain until they reach an exchange. And if something goes wrong, flag it from the chat itself. COMMUNITIES WITH REAL DOORS Token-gated groups that verify contract ownership. Subscription groups for creators. Group-level audit reports. Community signal channels carry a track-record score, so you can see how a channel has actually performed before you follow it. BUILT-IN DAPP BROWSER Open Uniswap or any dapp with your wallet already connected. No copy-paste, no separate extension. SPEAKS THE WAY YOU DO Set your language once and every message arrives in it. Not just Hindi or Tamil — Hinglish, Tanglish, Tenglish, Benglish, Punglish, Manglish and more. You type how you talk, they read how they talk. MINI APPS A growing app centre inside Sudo — escrow with independent dispute resolution, encrypted mail, domains, calculators, calling and more. Your keys stay on your device. Sudo never holds them. Sudo is free to use. Optional premium plans unlock higher AI Explorer limits, deeper fund tracing and team features.

VoidSend is a zero-knowledge encrypted messenger built for a post-quantum world. Every message, file, and call is encrypted on your device before it ever leaves — our servers act as a blind relay, mathematically unable to decrypt your data. ZERO-KNOWLEDGE ARCHITECTURE Unlike other messengers that promise privacy, VoidSend's Blind Relay design means the server only ever sees encrypted blobs. No plaintext. No metadata leaks. Your encryption keys never leave your device. POST-QUANTUM ENCRYPTION VoidSend uses hybrid encryption combining X25519 with ML-KEM-768 (Kyber), protecting your conversations against both today's threats and tomorrow's quantum computers. Messages are sealed with AES-256-GCM, and identities are verified with ML-DSA-65 post-quantum signatures. MESSAGING • End-to-end encrypted direct and group messages • Disappearing messages (5 seconds to 7 days) • Encrypted file sharing with automatic 24-hour server-side deletion • Emoji reactions, replies, and typing indicators • Message search across your conversation history VOICE & VIDEO CALLS • Peer-to-peer WebRTC audio and video calls • Optional post-quantum encrypted media streams • Call history WEB3 PAYMENTS (Only available on www.voidsend.xyz) • Built-in multi-chain wallet: Ethereum, Base, and Solana • Send and receive ETH, USDC, USDT, SOL, and SPL tokens • Wallet derived from your encryption seed — one identity, one key PASSWORDLESS AUTHENTICATION • Sign in with your crypto wallet (EIP-712 signature) • Or use Face ID / Touch ID with Passkeys • No email. No phone number. No passwords. Just you. STORIES & PROFILES • Share ephemeral photos and videos with your contacts • Custom avatars and usernames • Online status visible only to mutual contacts PRIVACY BY DESIGN • No data collection beyond your username and encrypted data • Block contacts and control who can message you • Cross-platform: your encrypted identity syncs seamlessly across all your devices VoidSend doesn't ask you to trust us — it's built so you don't have to.
