Wallet Development & Integration

Design, build, and integrate self-custodial wallet flows—secure UX, clean logic, and signer-ready systems built for real use.

What Makes Wallet Systems Fragile

Most wallet flows break not because of the UI, but because the underlying assumptions don’t scale with real usage or complexity.

One-Size-Fits-All Logic

Can’t handle different signers, chains, or use cases

Unreliable Onboarding

Poor fallback handling, dropped sessions, and missed connections

Surface-Level Security

No safeguards around approvals, nonce handling, or transaction simulation

Hardcoded Flows

No abstraction layer, difficult to adapt for custom dApps

Fragmented Setup

Disconnect between wallet UX, contract logic, and backend systems

End-to-End Wallet Development, Done Right

Full-stack wallet systems that support your product—not limit it.

Custom self-custodial wallets and signer logic

MetaMask, WalletConnect, multisig, and embedded wallets

Modular frontend flows tied directly to smart contracts

Gas estimation, nonce management, and transaction reliability

Custom wallet logic for DAOs, DeFi, and advanced user permissions

Full integration with backend services and user state management

From Design to Delivery: Our Wallet Build Process

Wallet systems that feel native to your stack—designed for flexibility and security from the start.

Scope user flows around your contract architecture and UX goals

Develop wallet logic with reusable components for signers, permissions, and session control

Build error-tolerant flows that handle edge cases cleanly

Review for contract alignment, signer security, and frontend consistency

Deliver clean, documented code with test coverage and support for future updates

FAQs

Do you support building new wallets or only integrating existing ones?

Both. We build self-custodial wallet systems from scratch or integrate with existing wallets like MetaMask, WalletConnect, or embedded SDKs, depending on what your product needs.

How do you handle private key management and security?

We follow best practices for self-custodial design, never storing keys or secrets on servers. We can implement secure signer flows, MPC integrations, or hardware wallet compatibility where needed.

Can the wallet support account abstraction or gasless transactions?

Yes. We work with ERC-4337, bundler integrations, and relayer networks to support smart accounts, session keys, and smoother UX without compromising on decentralization.

Will the wallet UX feel like Web2?

Absolutely. We design clean, secure, and intuitive flows that simplify onchain actions—so users don’t need to understand blockchain mechanics to interact with your app.

Can you support onboarding flows with social login or email wallets?

Yes. We’ve worked with integrations like Web3Auth and Magic.link to offer non-traditional wallet options without compromising on control or recovery paths.
