DeFi

DeFi protocols engineered as economic systems, not just contracts.

AMMs, lending, perps, and the economics that keep them solvent.

The problem

A DeFi protocol is an economic mechanism enforced by code in an adversarial market. The contracts can be flawless and the protocol can still fail — drained by an oracle manipulation, insolvent after a liquidation cascade it could not process fast enough, or slowly bled by an incentive design that pays attackers more than it pays users.

Shipping DeFi means getting three hard things right at once: secure contracts, sound economics, and reliable off-chain infrastructure. Most teams are strong at one and improvise the rest.

Our approach

We treat protocol design and engineering as one discipline. We model the economics, covering incentives, liquidation dynamics, oracle dependencies and worst-case scenarios, and stress them in simulation before committing to contracts. The contracts themselves carry our full smart-contract testing rigour.

Then we build the half of the protocol that lives off-chain: keepers, liquidators, oracle adapters, monitoring, and the runbooks that keep the system solvent and observable in production.

Scope of engagement

We build and ship full DeFi protocols: constant-product and concentrated-liquidity AMMs, order-book DEXs, lending and borrowing markets, perpetuals and synthetics, staking and restaking, and yield strategies. Each engagement spans economic modelling, audited contracts, keeper and oracle infrastructure, subgraphs, and the monitoring that protects TVL.

Common questions

Still unsure? A senior engineer will answer the specifics on a short scoping call.

Ask us directly

Yes. We model incentives, emissions, and liquidation dynamics, then simulate worst-case scenarios before parameters are locked in. Good DeFi engineering is inseparable from economic design, and we treat them as one engagement.

We use time-weighted and multi-source oracles, validate against on-chain liquidity depth, add circuit breakers for anomalous moves, and design liquidations to be robust to short-lived price dislocations. Oracle risk is modelled explicitly, not assumed away.
