overview
CORE INFRASTRUCTURE

Custom Smart Contract Development

Secure, gas-optimized smart contracts built to your exact specifications.

We architect and deploy production-grade smart contracts that form the foundation of your Web3 product. Our development process is built for security and efficiency from day one.

  • Security-First Architecture: Code written in Solidity 0.8+ with OpenZeppelin libraries and comprehensive unit/integration testing.
  • Gas Optimization: Every line is reviewed to minimize transaction costs, a critical factor for user adoption and protocol sustainability.
  • Full Audit Readiness: We deliver code structured for seamless third-party audits by firms like CertiK or Trail of Bits.

We don't just write code; we engineer the financial and operational logic that powers your protocol's trust layer.

Our team specializes in complex implementations:

  • DeFi Protocols: Custom AMMs, lending/borrowing systems, yield aggregators, and derivative contracts.
  • NFT Ecosystems: Advanced ERC-721A/ERC-1155 contracts with bespoke minting, staking, and royalty mechanics.
  • Enterprise & DAO Tooling: Multi-signature wallets, vesting schedules, and custom governance modules.

Deliverables & Process:

  • 2-Week MVP Sprint: Go from concept to a deployed, testnet-verified prototype.
  • Complete Technical Package: Source code, deployment scripts, comprehensive documentation, and a security review report.
  • Post-Deployment Support: We provide monitoring setup and maintenance plans to ensure long-term reliability.

Cross-Chain Slashing Protection

Frequently Asked Questions

Get clear answers on how our slashing protection system secures your validators across multiple chains and integrates with your operations.

Our system operates as a centralized, high-availability service that validators query before proposing or attesting blocks. It maintains a global, cryptographically signed database of validator attestations and proposals across all supported chains (Ethereum, Cosmos, Polkadot, etc.). When a validator client requests to sign, it queries our API. Our system checks the validator's recent activity across the entire network to prevent double-signing violations, returning an "ok to sign" or a "slashable offense detected" response. This prevents the validator from being slashed due to client bugs, operator errors, or faulty failover mechanisms.
