We architect and deploy custom smart contracts on EVM and Solana that are secure by design. Every contract undergoes a multi-stage audit process using industry-standard tools like Slither and Mythril before being reviewed by third-party security firms.

Gas Abstraction for Multi-Rollup Transactions
We design and implement meta-transaction systems and paymaster contracts that allow your users to pay for gas across multiple rollups using a single token or credit system, drastically simplifying the user experience.

overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Token Standards:
ERC-20,ERC-721,ERC-1155, andSPLtoken implementations. - DeFi Protocols: Custom DEXs, lending/borrowing pools, and yield strategies.
- Governance & DAOs: Voting mechanisms, treasury management, and proposal systems.
- Enterprise Logic: Supply chain tracking, credential verification, and asset tokenization.
We guarantee zero critical vulnerabilities in production, backed by a formal security audit report for every deployment.
Our contracts are built with upgradeability patterns (TransparentProxy, UUPS) and include comprehensive testing suites for 95%+ coverage. We deliver a production-ready MVP in 2-4 weeks.

END-TO-END SOLUTION
Our Gas Abstraction Implementation
We deliver a production-ready gas abstraction layer that eliminates user friction and operational overhead, allowing your users to transact seamlessly across multiple rollups without managing native gas tokens.
01
Multi-Rollup Paymaster Integration
Deploy a custom, audited Paymaster contract that sponsors gas fees for users on Arbitrum, Optimism, zkSync, and Base. We handle the complex relay logic and fund management, so you don't have to.

TANGIBLE RESULTS
Business Outcomes You Can Measure
Our gas abstraction infrastructure delivers quantifiable improvements in user experience, operational efficiency, and cost management. See the metrics that matter to your business.
01
Reduced User Drop-off
Eliminate the friction of native gas token acquisition. Users pay with any token, leading to a 90%+ reduction in transaction abandonment at the payment step.

Our Delivery Process
We deliver production-ready gas abstraction systems on a fixed timeline, from architectural design to mainnet deployment. Our process is built on battle-tested frameworks to ensure security and scalability from day one.
01
Architecture & Design Review
We conduct a deep technical assessment of your multi-chain strategy and user flows. We design a custom gas abstraction architecture, selecting optimal protocols (ERC-4337, Paymasters, Gas Stations) and rollup targets (Arbitrum, Optimism, Base, zkSync).

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by engineers who have deployed over 100 protocols.
We architect and deploy audit-ready smart contracts that form the foundation of your protocol. Our team specializes in Solidity 0.8+ and Vyper, leveraging battle-tested libraries like OpenZeppelin and implementing gas-optimized patterns to reduce user transaction costs by up to 40%.
- Custom Logic: From
ERC-20/721/1155tokens to complex DeFi primitives and DAO governance systems. - Security-First: Every line undergoes internal review against common vulnerabilities (
reentrancy,overflow) before formal audit. - Full Lifecycle: Development, testing (
Hardhat/Foundry), deployment, and post-launch monitoring and upgrade management via transparent proxies.
Deliver a secure, scalable smart contract suite in 2-4 weeks, not months. We ensure your core logic is immutable, efficient, and ready for mainnet.

Gas Abstraction: Key Questions
Common questions from teams evaluating multi-rollup gas abstraction solutions.
A standard integration for a single dApp takes 2-3 weeks from kickoff to production. For multi-chain deployments or complex protocol logic, timelines extend to 4-6 weeks. We provide a detailed project plan in the first week.
