Wallet Development & Integration
Wallet connectivity is the front door of every Web3 product. We implement wallet integration that works across all major wallets, handles network switches gracefully, and delivers the smooth onboarding experience Web3 needs to grow.
// Key benefits
What makes this service valuable
Universal wallet connectivity
MetaMask, WalletConnect v2, Coinbase Wallet, Phantom, and 300+ mobile wallets via WalletConnect. One integration that covers the entire wallet ecosystem.
Embedded wallets
Privy, Dynamic, and Magic link-based embedded wallets for Web3 apps that need to onboard non-crypto users without requiring them to install a wallet extension.
Multi-chain management
Network switching UI, chain detection, and wallet state management across EVM chains and non-EVM networks, with clear user communication at every step.
// Details
Wallet integration done right
Wallet integration is deceptively complex: disconnected state, wrong network, insufficient gas, and transaction rejection all need graceful handling. We implement wallet integration with production-quality error handling and state management.
For Web3 products targeting mainstream audiences, embedded wallets remove the barrier of requiring MetaMask. We implement Privy or Dynamic to provide email/social login that provisions wallets silently. For institutional custody, our fintech practice covers Fireblocks, MPC, and TSS patterns — see the fintech industry stack-depth section for corroboration.
// What this includes
- Wagmi v2 and Viem for EVM integration
- RainbowKit or ConnectKit wallet UI
- WalletConnect v2 mobile wallet support
- Privy / Dynamic embedded wallet
- Multi-chain network management
- Transaction state management
- Wallet session persistence

// In practice
How wallet development & integration engagements run
We typically anchor the first sprint on universal wallet connectivity. Wallet connectivity is the front door of every Web3 product. We implement wallet integration that works across all major wallets, handles network switches gracefully, and delivers the smooth onboarding experience Web3 needs to grow. On Residency Road engagements, discovery maps dependencies and success metrics before sprint one. Architecture choices, API contracts, and observability hooks are documented before the first production deploy.

// FAQ
Common questions about wallet development & integration
What is an embedded wallet and when should I use it?+
Embedded wallets (Privy, Dynamic, Magic) create wallets on behalf of users using email or social login, users never see seed phrases. Use them when targeting non-crypto audiences. For crypto-native audiences, browser wallets (MetaMask) are preferred.
Can you integrate wallet sign-in with a traditional backend?+
Yes, Sign-In with Ethereum (SIWE) enables wallet-based authentication with a traditional session-based backend. We implement SIWE with JWT issuance so your backend handles users identically to traditional auth.
