On-chain.
Production-grade.
Smart contracts, token infrastructure, wallet integrations, and dApps. Built with the same engineering rigor as any other production system — no cowboy deployments.
Smart contract development
Solidity contracts written to production standards — gas-optimized, tested, and reviewed before they go anywhere near mainnet.
Smart contract auditing
Security review of existing contracts: reentrancy, integer overflow, access control flaws, and logic errors that scanners miss.
Token infrastructure
ERC-20, ERC-721, ERC-1155 — standard and custom token contracts with deployment scripts, verification, and front-end integration.
DeFi protocol development
Liquidity pools, staking contracts, vaults, and lending protocols built on established patterns with custom logic where your use case demands it.
Wallet & Web3 integration
Frontend integration with MetaMask, WalletConnect, and other wallet providers — including transaction signing, event listening, and error handling.
Multi-chain deployment
Ethereum, Base, Polygon, Arbitrum, Solana — we deploy where your users are and handle the cross-chain complexity so you don't have to.
Contracts are immutable.
We test like it matters.
Smart contract bugs don't get patched with a hotfix — they get exploited. Our development process treats contract security as a first-class concern: every function has unit tests, every edge case has a test, and critical contracts get an independent review before mainnet.
We deploy to testnet first, always. You get a working application to review against real on-chain behavior before we touch mainnet funds. The extra week this takes has saved clients far more than it cost.
- Fully tested smart contracts with unit test suite
- Deployment scripts for testnet and mainnet
- Contract verification on Etherscan / block explorer
- Security audit report if requested
- Frontend Web3 integration
- Post-deployment monitoring setup
Building on-chain requires getting the security right the first time.
Smart contracts are immutable by default. Once deployed to mainnet, the code is there — and if there's a vulnerability in it, so is the vulnerability. This is what makes blockchain development fundamentally different from traditional software: you don't push a hotfix. The consequences of a bug range from inconvenient to catastrophic, which is why security review isn't optional for any contract that handles value.
We work primarily on Ethereum and EVM-compatible chains (Polygon, Arbitrum, Base, Optimism) and Solana. Chain selection is a product decision that depends on transaction costs, throughput requirements, ecosystem tooling, and where your users are. We help you make that decision with a clear-eyed view of the trade-offs — not a preference for whatever chain we happen to know best.
Most Web3 projects fail for non-technical reasons — unclear tokenomics, a community that never materializes, a product that doesn't need decentralization but uses it anyway. We're direct about this. If a traditional database would solve your problem better than a blockchain, we'll tell you.
Common questions
Everything you need to know before getting started.
Primarily Ethereum, Solana, and EVM-compatible L2s including Polygon, Arbitrum, Base, and Optimism. Chain selection depends on your project's requirements — transaction costs, throughput, ecosystem, and where your users are. We help you choose before we start building.
All contracts go through internal review before deployment to testnet. For contracts handling significant value, we recommend a third-party audit from a specialized security firm — we can facilitate this and work with the auditors on remediation. We do not deploy unaudited contracts to mainnet for high-stakes use cases.
Yes. A dApp is a smart contract plus a web interface — and both need to be well-built for the product to work. We build the full stack: contracts, indexers where needed, and the web app that users interact with. Wallet connection, transaction flows, and on-chain data display are all part of the build.
A fungible token (ERC-20) is interchangeable — each unit is identical, like currency. An NFT (ERC-721 or ERC-1155) is non-fungible — each token is unique and carries distinct metadata. The right structure depends on what you're trying to represent and how you want the economics to work.
Yes. We do code review for existing contracts — looking for common vulnerability classes (reentrancy, integer overflow, access control issues, oracle manipulation) and providing a written report with severity ratings and remediation guidance.
