We integrate wallets seamlessly into your dApp. MetaMask, WalletConnect, Coinbase Wallet, and smart wallets — connected with multi-chain support and polished UX.
The wallet connection is the front door of every Web3 application. If it is confusing, unreliable, or limited to a single wallet type, you lose users before they ever interact with your product. Arthiq builds wallet integrations that support all major providers, handle multi-chain switching gracefully, and provide the polished experience that mainstream users expect.
Our wallet integration work uses wagmi and viem as the foundation, providing type-safe interaction with EVM chains and support for the full spectrum of wallet providers — browser extensions like MetaMask, mobile wallets through WalletConnect, institutional wallets like Fireblocks, and smart wallets like Coinbase Smart Wallet that use passkey authentication.
We have integrated wallets into DeFi applications, NFT platforms, DAO interfaces, and consumer dApps. Each application type has its own wallet UX requirements — a DeFi protocol needs transaction simulation and approval management, while a consumer app needs invisible wallet creation. We design the integration to match your application's specific user journey.
Modern dApps often operate across multiple chains, and the wallet experience must handle chain switching without friction. We implement automatic chain switching that prompts users when they are on the wrong network, adds missing chains to their wallet configuration, and maintains connection state across chain changes.
For applications that deploy on Ethereum, Polygon, Arbitrum, Base, and Optimism, we build unified interfaces where users can interact with any chain without manually switching networks. The application detects the required chain for each action and handles the switching transparently.
We also implement chain-aware balance displays, showing users their assets across all supported networks in a single view. This multi-chain awareness extends to transaction history, pending transactions, and activity feeds that aggregate data from multiple chains.
The next wave of Web3 adoption depends on smart wallets and account abstraction that eliminate the barriers of seed phrase management and gas token acquisition. We integrate ERC-4337 smart wallets, Coinbase Smart Wallet, and custom account abstraction solutions that provide seamless onboarding.
Our smart wallet integrations include passkey-based authentication where users create wallets with biometric verification, sponsored transactions where your application covers gas costs, batched transactions that combine multiple operations into single confirmations, and session keys that allow pre-approved actions without repeated signing.
For applications that need to onboard Web2 users, we implement embedded wallet solutions where wallet creation happens automatically during account registration. Users interact with your application using familiar authentication methods — email, social login, passkeys — while all transactions are recorded on-chain through their smart wallet.
Beyond connection, we build robust transaction management that handles the full lifecycle — estimation, signing, submission, confirmation, and error handling. Users see clear transaction previews with estimated gas costs, token approvals with explanation, and real-time status updates as transactions are confirmed.
We implement EIP-712 typed data signing for gasless actions like order placement and governance voting. Our signature handling includes domain separator validation, nonce management, and signature verification that prevents replay attacks. For applications with permit-based approvals, we implement EIP-2612 permits that save users a separate approval transaction.
Error handling is designed for clarity. When a transaction fails, users see a human-readable explanation — insufficient balance, slippage exceeded, contract reverted — rather than cryptic error codes. We implement transaction retry logic for transient failures and provide manual gas adjustment options for congested network conditions.
Wallet integration bugs are immediately visible to users and destroy confidence in your application. We test wallet flows across multiple browsers, devices, and wallet providers to ensure consistent behavior. Our testing covers connection flows, chain switching, transaction signing, disconnection, and reconnection scenarios.
We implement connection persistence so that returning users are automatically reconnected to their last-used wallet. Session management handles wallet locking, account switching, and wallet provider changes without requiring users to refresh the page or re-enter the application.
Arthiq builds wallet integrations that just work — across every major provider, every supported chain, and every device your users access. Our Singapore-based team has integrated wallets into applications handling significant transaction volume. Contact founders@arthiq.co to improve your dApp's wallet experience.
