overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 specialists for your protocol or application.

We architect and deploy the foundational logic for your dApp. Our team delivers audit-ready code in Solidity, Rust, or Vyper, ensuring security and gas efficiency from day one.

  • Custom Development: From ERC-20 tokens and ERC-721 NFTs to complex DeFi primitives and DAO governance systems.
  • Security-First: Built with OpenZeppelin standards, comprehensive unit testing, and integration with leading audit firms.
  • Full Lifecycle: We handle development, deployment to mainnet/testnet, and provide ongoing upgrade management.

Reduce your time-to-market and technical risk with contracts built for scale. We focus on security, maintainability, and clear documentation so your team can build with confidence.

Business Outcomes: Beyond Technical Abstraction

Our Universal Gas & Fee Abstraction SDK delivers more than developer convenience. It creates tangible business advantages that accelerate your go-to-market, reduce operational friction, and unlock new revenue streams.

01

Accelerate User Onboarding

Remove the #1 barrier to adoption—cryptocurrency pre-funding. Users can start transacting immediately with credit cards or stablecoins, reducing signup-to-transaction time from days to seconds. This directly impacts your activation and retention metrics.

Frequently Asked Questions

Get clear answers on how our SDK simplifies gas complexity for your users and accelerates your product launch.

Our SDK abstracts the complexity of blockchain transaction fees for end-users. It enables you to offer gasless transactions, pay fees in any ERC-20 token, or sponsor user fees entirely. This removes a major UX barrier, allowing your users to interact with your dApp without needing native tokens for gas, understanding fluctuating gas prices, or managing multiple wallet balances.
