What it is
Decentralised finance (DeFi) refers to financial protocols built on public blockchains that provide lending, trading, yield generation, and derivatives without centralised intermediaries — where protocol rules are enforced by smart contracts rather than institutions.
What you get
DeFi protocols are the most adversarially tested smart contract systems in existence. Billions of dollars flow through them daily, and sophisticated attackers probe them continuously. Building a DeFi protocol requires deep knowledge of economic attack surfaces — flash loans, oracle manipulation, MEV, liquidity attacks — not just Solidity proficiency.
We build AMMs, lending and borrowing markets, liquid staking protocols, on-chain derivatives, and yield optimisation vaults. Architecture is designed around capital efficiency, liquidity incentive mechanics, and governance structures that can evolve without compromising user funds.
Security is non-negotiable. Every DeFi engagement includes economic security modelling alongside code audits, oracle design with manipulation resistance (TWAP, Chainlink, Pyth), formal invariant testing with Foundry, and a bug bounty programme recommendation before mainnet deployment.
Key capabilities
Each engagement is scoped to your requirements — these are the core capabilities we bring to the table.
On-chain derivatives and structured products
Yield vault and auto-compounding strategy contracts
Oracle integration (Chainlink, Pyth, TWAP) with manipulation resistance
On-chain governance with timelock and voting contracts
Economic security modelling and attack simulation
Our process
A structured, engineering-led approach that moves from understanding your goals to a production system — with no handoff surprises.
Typical engagement
8–16 WEEKS
We map your goals, constraints, and existing infrastructure. Scope is defined and success criteria agreed before any development begins.
We design the technical approach, select the right tools, and produce a milestone-driven delivery plan with no ambiguity.
Iterative development with regular demos. Code reviews, test coverage, and documentation happen in parallel — not at the end.
Production release with monitoring setup and handover documentation. We stay close during the first weeks post-launch.
Flash loan attacks exploit price oracles or protocol state within a single transaction. Defences include: using time-weighted average prices (TWAP) rather than spot prices for oracle reads, adding reentrancy guards, requiring multi-block confirmation for sensitive state changes, and setting circuit breakers that pause the protocol when anomalous activity is detected.
Tokenomics are designed around the incentive structures needed for the protocol to function: liquidity provider fees, governance token distribution, staking rewards, and treasury allocation. We model these using agent-based simulations to identify incentive misalignments before they become exploits or economic failures.
Regulatory treatment of DeFi is evolving. We build protocols with compliance hooks where regulators may require them: KYC layers for institutional pools, geographic access restrictions, and upgrade paths that can add compliance controls without requiring a full redeploy. Your legal counsel defines the requirements; we implement them technically.
