Wallet Engineering

Web3 Wallet Development

Secure, multi-chain wallets your users will trust — mobile, browser, and embedded.

We build production-grade Web3 wallets used by millions: mobile apps, browser extensions, embedded SDKs, MPC vaults, and abstraction-layer smart accounts. Every wallet ships with key management, gas sponsorship, and dApp connectivity baked in.

What We Build

Everything you need, end-to-end

Mobile Wallets

Native iOS / Android wallets with biometric unlock, push signing, and multi-chain support out of the box.

Browser Extensions

Lightweight Chrome / Firefox extensions with dApp connectors, EIP-1193 providers, and hardware wallet bridges.

MPC & Multi-Sig Vaults

Threshold-signature and multi-sig infrastructure for treasuries, DAOs, and institutional custody.

Account Abstraction

ERC-4337 smart accounts with paymasters, session keys, and social recovery flows.

Embedded Wallet SDKs

White-label SDKs so your app onboards Web2 users with email or social login — wallets generated invisibly.

Security & Audits

Third-party audits, formal verification, secure enclave integration, and pen-tested signing flows.

Our Process

How we ship

  1. 01

    Discovery

    We map your users, chains, custody model, and compliance needs into a technical spec.

  2. 02

    Architecture

    AI-assisted C4 diagrams covering key storage, signing flows, RPC routing, and recovery.

  3. 03

    Build

    Sprint-based development with weekly demos. Cross-platform from day one.

  4. 04

    Audit

    Independent security audit, fuzz testing, and bounty-program kickoff before launch.

  5. 05

    Launch & Ops

    Mainnet deployment, monitoring, hot-fix retainer, and ongoing chain integrations.

ERC-4337 (Ethereum & L2s: Optimism, Base, etc.)LIVE

Smart Account Abstraction Wallet: Next-gen Infrastructure

We contributed to the development of an Abstracted Wallet built on ERC-4337, delivering seamless, gasless, and secure Web3 access for mainstream adoption. This modular wallet stack integrates pluggable modules for chain-specific logic, advanced bundler/paymaster routing, and ZK-supported workflows for identity and collateral validation. With support for real-world assets (RWAs), NFTs, and soulbound tokens (SBTs), the Abstracted Wallet unifies identity, asset management, and transaction orchestration in a cross-platform UX spanning mobile, web, and desktop.

MPC Wallet: Secure Sharded Key Infrastructure

We developed a Multi-Party Computation (MPC) wallet that leverages Shamir’s Secret Sharing protocol for key sharding and secure custody. By distributing private key shares across multiple parties, the solution eliminates single points of failure while ensuring secure signing operations. This wallet stack provides enterprise-grade security, flexibility for institutional adoption, and seamless integration with dApps through standardized abstraction layers. The MPC Wallet is designed for developers, institutions, and retail users who require secure, scalable, and recovery-ready key management.

Logistics With Web3: A Decentralized Ecosystem

We excel in the role of Blockchain Architects, resolving critical logistics challenges through innovative Web3 solutions. This project simplifies logistics for non-Web3 users by bridging technical barriers, tokenizing space consumption for efficient resource allocation, streamlining decentralization onboarding, and enhancing asset location traceability across the Web3.0 landscape. With successful implementations, our work demonstrates how transparency, efficiency, and security can be achieved in modern logistics.
