A mobile-first crypto wallet designed for secure self-custody with MPC signing, passkey authentication, and creative on-device AI tools. 

Security-first wallet design 

Regen Tech developed a cross-platform crypto wallet app that reimagines the self-custodial experience. Built as the mobile participant in a multi-party computation (MPC) network, the wallet eliminates traditional risks like seed phrase exposure and single points of compromise. 

This wallet integrates with the MPC SDK developed for our client and participates in threshold signing operations, initially in 2-of-3 configurations involving mobile, cloud, and hardware parties. A t-of-n rollout is planned, expanding signing policies for more complex security needs. 

Authentication is handled through Passkey (FIDO2) login, enabling passwordless access using biometrics and secure enclave-based credentials. Users gain secure, phishing-resistant access to their wallet without needing to remember or protect a recovery phrase. 

Full compatibility & seamless recovery 

This wallet complies with BIP32/39 standards, allowing: 

• Import of existing wallets (e.g., MetaMask) and conversion to MPC format 

• Export to other wallet platforms if needed 

For backup and recovery, encrypted shards are stored across mobile, cloud, and optionally hardware. This structure ensures that users retain full custody without relying on any single device or custodian. 

Web3 connectivity and dApp interaction 

The wallet supports connection to decentralized applications via WalletConnect and provides multi-chain support for: 

• Tron 

• Binance Smart Chain (BSC) 

• Bitcoin (BTC) 

• Toncoin (TON) 

• Ripple (XRP) 

Users can send, receive, and manage assets from a single UI, without switching wallets or compromising security. Full compatibility & seamless recovery 

On-device AI tools 

As a creative layer atop its secure foundation, the wallet includes an AI engine offering: 

• Text-to-image generation 

• Face & style transformation 

• Face fusion 

• Pose augmentation 

• Image enhancement 

The app also supports steganography, allowing users to embed encrypted messages into visual media. Minting NFTs is supported directly within the app, eliminating the need for third-party platforms. 

UX and platform design 

The wallet runs on both iOS and Android and is built with Flutter using native Kotlin and Swift SDKs under the hood. Monthly updates deliver UI refinements, dApp support improvements, and security enhancements. 

Passkey login provides seamless entry without credential management. MPC signing operates silently in the background, coordinating with the cloud and (in future versions) with browser and hardware signers. 

Technical challenges and engineering outcomes 

Developing this wallet presented challenges including: 

• Multi-device coordination for real-time MPC messaging 

• Seamless Passkey integration across mobile platforms 

• Balancing AI processing performance with app responsiveness 

Our approach combined deep native SDK integration with modular architecture and robust CI/CD automation. 

The wallet is designed for: 

• Crypto users who want maximum security and usability 

• Web3 enthusiasts seeking multi-chain and dApp support 

• Users who want creative freedom through AI features and NFT minting 

This app serves as a reference-grade mobile participant in an MPC signing network, demonstrating what modern, secure self-custody can look like.
