What We Shipped
Account Abstraction smart accounts (ERC-4337)
Smart contract accounts enable programmable key recovery, batch transactions, and flexible gas sponsorship.
Social login key distribution
Users sign in through Google or Apple accounts while cryptographic key shares remain generated and secured locally on user devices.
Browser core integration
The wallet is embedded directly into the Herond Browser core and not running as a third-party browser extension.
Multi-chain dApp connectivity
We integrated WalletConnect and native RPC providers across Ethereum, Polygon, Arbitrum, BNB Chain, and Solana.
Automated token swap routing
An automated swap router splits and routes token trades through decentralized liquidity pools for optimal pricing.
Problem & Context
Traditional Web3 onboarding forces users to manually write down 12-word seed phrases, configure custom RPC endpoints, and estimate gas fees. These friction points cause most first-time users to drop off before completing their first transaction.
Our objective was to streamline the onboarding flow while ensuring users retain exclusive cryptographic ownership of their private keys without third-party custody.
Engineering Challenges
Eliminating seed phrases while preserving non-custodial ownership
We implemented programmable key recovery so users never have to write down recovery phrases, while ensuring our backend servers cannot sign or access user transactions.
Hardware-level key isolation across 4 platforms
The application interfaces with Apple Secure Enclave on iOS and macOS, Android Keystore, and hardware security modules on Windows to enforce strict key isolation.
Real-time on-chain transaction monitoring
The client listens to mempool broadcasts and block confirmations to provide accurate, real-time transaction states before and after finality.
Operational outcomes
- 3
- simple steps to set up a new wallet
- ~10s
- average onboarding time
- 99%
- transaction success rate
- EVM & Solana
- blockchain ecosystems supported
Users get a functional non-custodial wallet in ~10 seconds via social sign-in while retaining absolute ownership of their cryptographic keys.
Dynamic chain configuration allows connecting new EVM networks remotely without pushing native binary updates.
How this benefits client projects
Key security architecture, battle-tested smart contracts, and ERC-4337 onboarding patterns carry directly into client Web3 and fintech applications.
