Smart contracts written for security first
Smart contracts are programs that run on a blockchain and, once deployed, can be very hard to change. Mistakes can be permanent and expensive, so the discipline is different from ordinary software: simple designs, extensive testing and independent review.
Smart contracts are programs that run on a blockchain and, once deployed, can be very hard to change. Mistakes can be permanent and expensive, so the discipline is different from ordinary software: simple designs, extensive testing and independent review. We build contracts that do what they are meant to do and nothing else.
What’s included
- Requirements and design: what must live on-chain and what should stay off-chain
- Development in Solidity for EVM chains, and other languages such as Rust where the chain requires
- Standard token and access patterns (ERC-20, ERC-721, ERC-1155, multisig, role-based access) using audited libraries
- Comprehensive testing with Foundry or Hardhat, including fuzzing and invariant tests
- Gas optimisation and deployment scripts for testnets and mainnet
- Upgradeability and governance design, with the trade-offs explained
- Documentation and preparation for an independent audit
Best for
Startups building token, marketplace, DeFi or loyalty products, and enterprises exploring tokenised assets or on-chain workflows.
How we work
- Decide whether and where a blockchain fits. 2) Design the contract architecture and threat model. 3) Build with tests. 4) Audit, deploy and monitor.
What you receive
Tested, documented contracts, deployment scripts, test reports and audit-ready repository.
The result
On-chain logic that is understandable, tested and ready for review.
Frequently asked questions
Do we definitely need a blockchain?
Not always. If a conventional database does the job, we will say so. See our note on when blockchain fits.
Which chain should we use?
It depends on cost, security, ecosystem and users. We compare options against your requirements.
