Blockchain & Web3
Decentralised systems, built to be audited.
Smart contracts, exchanges and wallets delivered with the same engineering discipline as the rest of our work — because on-chain, a bug is permanent and public.
What this covers
The whole surface, not the headline.
Smart contracts
- Solidity contract design and development
- Upgradeable proxy patterns
- Gas optimisation
- Access control and role management
- Formal specification of contract behaviour
- Deployment scripts and verified source
Protocols & exchange
- Automated market maker and DEX platforms
- Cross-chain bridges and DEX aggregators
- Staking, farming and liquidity rewards
- Tokenomics modelling and simulation
- Oracle integration for off-chain data
- Multi-chain deployment strategy
Applications
- DApp front ends with wallet connection
- Custodial and non-custodial wallets
- NFT marketplaces and minting platforms
- On-chain identity and credentials
- Payment rails inside existing products
- Fiat on-ramp and off-ramp integration
Security
- Security-first development with threat modelling
- Internal audit before external audit
- Reentrancy, overflow and oracle-manipulation review
- Test coverage including adversarial cases
- Testnet and mainnet-fork rehearsal
- Incident and pause procedures
Infrastructure
- Node operation and RPC reliability
- Indexing and subgraph development
- Event monitoring and alerting
- Key management and multisig operations
- Transaction retry and nonce handling
- Cost monitoring across chains
Compliance
- KYC and AML integration where required
- Sanctions screening
- Jurisdictional review before launch
- Transparent, auditable on-chain records
- Treasury and governance process
- Documentation for regulators and exchanges
How we deliver it
The same five stages, every engagement.
01
Discover
We map how the work actually flows today — the handoffs, the workarounds, the spreadsheet nobody admits to. That map, not the org chart, is what we build against.
02
Architect
We design the system end to end before writing production code: data model, integration surface, failure modes, and what happens when the model is wrong.
03
Build
Agile delivery in small teams, working to a documented process. Short cycles, working software, and no six-month gap between kickoff and something you can use.
04
Deploy
Into your environment, against your compliance requirements, with the monitoring and audit trail a regulated operation needs from day one.
05
Operate
Systems drift. We stay on to retrain models, watch the metrics that matter, and keep the thing working after the launch photo.
