Blockchain & Web3
Smart contracts, DeFi protocols, and on-chain infrastructure.
What we do for you
We write smart contracts that work on mainnet — audited, battle-tested, and optimised for gas. From ERC-20 tokens to complex multi-sig DeFi protocols, we have deployed across Ethereum, Polygon, Arbitrum, Solana, and custom L2 chains.
Every contract we write goes through internal audit and formal verification where applicable. We use Foundry and Hardhat for testing, and we don't ship anything that hasn't been stress-tested with fuzzing and invariant tests.
We also build the off-chain infrastructure — indexers, subgraphs, relayers, and event-driven backends — that make on-chain applications actually usable.
What's included
- Smart contract development & audit
- DeFi protocol design & deployment
- NFT & token contract engineering
- On-chain data indexing (The Graph)
- Cross-chain bridge development
- Wallet integration & account abstraction
- Gas optimisation & security hardening
The specifics
Every engagement draws on a specific combination of these capabilities — applied by engineers who've done it in production.
Smart Contract Dev
Solidity, Rust (Solana), Vyper — with formal verification.
Security & Auditing
Internal audit, fuzzing, and invariant testing with Echidna.
DeFi Protocol Design
AMMs, lending protocols, yield strategies, and governance.
Cross-chain Infrastructure
Bridge development, LayerZero, Wormhole integrations.
Indexing & Subgraphs
The Graph, custom indexers, on-chain event pipelines.
Wallet & AA
ERC-4337 account abstraction, multi-sig, and WalletConnect.
Blockchain & Web3 in production
Real projects. Real outcomes. No case study padding.
Tools chosen for the job,
not the trend.
Every technology decision in a Blockchain & Web3 engagement is made against real constraints — performance targets, compliance requirements, team familiarity, and long-term maintainability. We'll tell you which choices are wrong for your situation.
