Web3 Multi-Wallet Integration

Reference implementation for integrating multiple Web3 wallet providers using Wagmi connectors

Problem

dApps increasingly need to support several wallet providers — browser extensions, embedded wallets, enterprise SDKs, and multi-chain aggregators — but each ships its own SDK, connection lifecycle, and state model. Integrating them ad-hoc leads to duplicated connect/disconnect logic, inconsistent signing UX, and provider-specific bugs that surface only in production. A reference implementation establishing one unified integration pattern was needed.

Approach

  • Wagmi as the single abstraction layer: its connector interface normalizes connection state and hook usage across providers, so application code depends on Wagmi rather than on any one wallet SDK.
  • Custom connectors per provider to adapt each SDK into Wagmi’s contract, isolating provider-specific quirks behind a uniform interface.
  • Modular connector architecture so adding or removing a provider is a file-level change rather than an application-wide refactor.
  • Provider-agnostic signing path to keep transaction UI consistent regardless of which wallet is active.
  • Vite + TypeScript for fast iteration on a reference application whose primary purpose is to be read and copied.

Implementation

Connector Implementations

  • MetaMask — Standard browser extension wallet
  • Privy — Embedded wallet with social login
  • Privy + Wagmi — Combined Privy authentication with Wagmi hooks
  • Wepin SDK — Enterprise wallet SDK integration
  • Dynamic — Multi-chain wallet aggregation

Unified Integration Layer

  • Unified wallet connection interface across providers
  • Consistent state management via Wagmi hooks
  • Provider-agnostic transaction signing
  • Modular connector architecture for easy extension

Outcome

  • Reference implementation covering five wallet providers (MetaMask, Privy, Privy+Wagmi, Wepin, Dynamic) through a single Wagmi-based integration surface.
  • Connector pattern that isolates provider-specific code so new wallets can be added without touching application logic.
  • Consistent signing and state semantics across providers for downstream dApp authors.

Technologies

  • Framework: Vite + TypeScript
