Code you can't patch after deploy
On-chain code is immutable and public, which changes how it has to be written and reviewed. Smart contracts, wallet integration, and the off-chain half where most of the system actually lives.
What we actually build
Three areas, and the part of each that tends to bite.
Smart Contract Development
Contracts you cannot patch once deployed, so the review happens before the deploy rather than after it. Upgrade paths and admin keys are design decisions with permanent consequences — better to argue about them early.
- Ethereum (Solidity)
- Hyperledger Fabric
- Polygon & Layer 2 solutions
DeFi Application Development
Lending, swaps and settlement logic, where a rounding error is a withdrawal. Expect adversarial review, property tests around the accounting, and an explicit answer for what happens when an oracle lies.
- Decentralized exchanges
- Lending & borrowing platforms
- Yield farming
Enterprise Blockchain Solutions
Permissioned ledgers between parties who do not fully trust each other. The honest first question is whether a shared database with signed writes would do the same job — sometimes it would, and we will say so.
- Supply chain tracking
- Document verification
- Cross-border transactions
Two we can describe
No client names and no invented numbers — just what each system had to do.
Blockchain-Powered Supply Chain for a Manufacturing Business
A permissioned ledger recording custody handoffs between suppliers, so a disputed shipment had one shared history instead of four spreadsheets that disagreed.
DeFi Platform for Institutional Lending
An institutional lending platform with compliance checks in the issuance path and settlement on-chain, built so positions could be reconciled against the chain itself rather than trusted from a dashboard.
Does this need a chain at all?
Frequently it doesn't. Tell us what you need to make verifiable and between whom, and we will tell you honestly whether a ledger earns its cost here.
