Exodua — Web3 Wallet for Secure, Simple Crypto

A lightweight, multi-chain wallet designed for power users and newcomers alike. Secure on-device keys, seamless dApp connections, and polished UX for managing crypto, NFTs and DeFi.

Overview

Exodua is built around three priorities: security, simplicity, and composability. Whether you need to sign a contract, view an NFT, or swap tokens across chains, Exodua puts a single, auditable seed and clear UX at the center of your experience. This document describes the product, how it works, and how to get started.

Key features

1
Hardware-level key safety
Industry-grade key derivation with optional secure element support and mnemonic backup.
2
Multi-chain support
Ethereum and EVM-compatible chains, Solana, and selectively integrated L2s with intuitive network management.
3
dApp & Web3-ready
WalletConnect and injected-provider support for seamless connections to marketplaces, DEXs and social dApps.
4
NFT gallery & media
On-device indexing and light previews; art-forward UIs with provenance metadata and display settings.

Security model

Exodua separates signing authority from network interaction. Keys are generated locally using BIP-39/BIP-44 standards and protected by an optional Secure Element or OS-level keystore. Transaction signing is explicit — the user reviews human-readable transaction fields before any approval, and advanced users can inspect raw RLP/serialized payloads. Recovery uses a mnemonic phrase and a guided, clear backup flow; we encourage hardware backups for high-value accounts.

How Exodua handles privacy

No personal data is required to use Exodua. The wallet avoids centralized analytics by default — opt-in telemetry is available for those who want to help improve the product. IP-level privacy is the responsibility of the network; Exodua supports configurable RPC endpoints and private relay integrations for advanced users.

Design & UX

The interface favors clarity: balances are shown with fiat conversions, pending transactions show countdowns and nonce details, and action flows minimize surprise by showing gas estimates, fee breakdowns, and optional nonce locks for manual chain management. Onboarding includes a short interactive tutorial explaining seed backup, secure passphrase options, and how to connect to a dApp safely.

Integration & developer notes

Exodua exposes a secure provider shim compatible with the EIP-1193 spec and supports WalletConnect v2 for mobile bridging. Developers can request metadata (chainId, accounts, supportedMethods) and will receive clear user prompts for every signature or permission request. A lightweight JSON-RPC proxy allows per-origin rate limits and optional transaction previews for enhanced UX.

Getting started — quick steps

  1. Create a new wallet or import existing seed (BIP-39). Choose an on-device passcode and enable biometric unlock if desired.
  2. Backup your mnemonic using the guided checklist. Verify at least once by re-entering a subset of words.
  3. Add networks you use — default lists include major EVM chains; advanced users can add custom RPCs.
  4. Connect to dApps via WalletConnect or the injected provider. Review permissions carefully: read-only vs signing vs spending approvals differ.
  5. For high-value accounts, pair Exodua with an external hardware device for signing or enable the secure element option.

Common use-cases

  • Secure day-to-day wallet for trades, swaps, and NFT purchases.
  • Developer-friendly testing across chains using custom RPC endpoints.
  • Account custodianship using multi-sig-friendly workflows and third-party guardians.
  • Offline signing workflows for institutional or high-value transactions.

Roadmap highlights

  • Seedless recovery experiments using social recovery primitives and threshold cryptography.
  • Native hardware wallet integrations and a certified secure element module for mass-market devices.
  • On-chain identity and verifiable credential display for KYC-lite professional dApps (optional opt-in features).
  • Enhanced privacy mode with onion-routing RPC relays and selective metadata obfuscation.
