overview

CORE SERVICE

Smart Contract Development

Secure, audited smart contract systems built for production from day one.

We architect and deploy custom smart contracts that form the backbone of your protocol. Our development process is built for security and scale, delivering production-ready code in weeks, not months.

End-to-end lifecycle: From initial design and Solidity/Rust development to deployment and on-chain monitoring.
Security-first approach: All code follows OpenZeppelin standards and undergoes rigorous internal review before external audit.
Gas optimization: We write efficient contracts to minimize user transaction costs, a critical factor for adoption.

We don't just write contracts; we engineer the financial and governance logic that defines your application's trust and functionality.

Our team specializes in complex implementations:

DeFi Primitives: Custom AMMs, lending pools, yield aggregators, and derivative contracts.
Token Standards: ERC-20, ERC-721, ERC-1155, and bespoke tokenomics with vesting and minting controls.
Cross-chain & Layer 2: Native development for Ethereum, Polygon, Arbitrum, Base, and other EVM-compatible networks.

ENTERPRISE-GRADE FEATURES

Core Smart Wallet Capabilities We Implement

We build modular, secure smart wallet interfaces with battle-tested capabilities that accelerate your product roadmap and enhance user security.

Gas Sponsorship & Abstraction

Implement gasless transactions and fee delegation via ERC-4337 Paymasters. Remove onboarding friction by allowing users to pay fees in any ERC-20 token or have sponsors cover costs.

ERC-4337

Standard

0 Gas

User Onboarding

Social Login & Key Management

Replace seed phrases with Web2-style social logins (Google, Apple) and embedded MPC wallets. Enable secure, non-custodial account recovery and seamless cross-device access.

MPC-Based

Security

OAuth 2.0

Integration

Batch & Session Transactions

Bundle multiple operations into a single transaction to reduce gas costs and improve UX. Implement session keys for time or scope-limited permissions in dApps and games.

Gas Savings

UserOps

Bundler API

Multi-Signature & Policy Engine

Deploy flexible multi-sig schemes for treasury or team wallets. Integrate a rules engine for transaction limits, whitelists, and time-locks to enforce security policies.

M-of-N

Flexible Signing

MEASURABLE IMPACT

Business Outcomes: Beyond Better UX

Our Account Abstraction interface design delivers tangible business results, from accelerating user growth to unlocking new revenue streams. Here’s what you can expect.

Accelerated User Onboarding

Replace complex seed phrases with familiar Web2 login flows (social, email, passkeys). We deliver a frictionless first-time experience that reduces drop-off by up to 80% and cuts time-to-first-transaction from minutes to seconds.

80%

Reduced Drop-off

< 30 sec

First Transaction

Enhanced Security & Reduced Liability

Implement session keys, spending limits, and multi-signature recovery. We design interfaces that make advanced security user-friendly, reducing support tickets for lost keys by over 95% and minimizing protocol exposure to user error.

95%

Fewer Key-Loss Tickets

SOC 2

Compliant Design

Unlock Gasless & Sponsored Transactions

Design seamless flows for paymaster integrations, allowing users to transact without holding native tokens. This removes a major adoption barrier, increasing conversion rates for premium features by 3-5x and enabling new business models.

3-5x

Premium Feature Uptake

0 ETH

User Entry Cost

Drive Higher Engagement & Retention

Craft intuitive dashboards for batch transactions, automated subscriptions (ERC-4337), and real-time status updates. We build interfaces that encourage repeat usage, boosting user session duration by 40%+ and improving core metric retention.

40%+

Longer Sessions

D7 Retention

Future-Proof Compliance & Audit Trails

Design with regulatory clarity in mind. We implement clear transaction labeling, embedded KYC/AML flows, and comprehensive activity logs, providing the auditable transparency required for institutional and enterprise adoption.
