Plateformes DeFi
Ingénierie de protocoles et d’interfaces de finance décentralisée — mécanismes de prêt, d’échange et de coffres — avec contrôle des risques, sécurité des oracles et préparation à l’audit intégrés dès la conception.
Vue d’ensemble
Decentralized finance concentrates risk in code. A pricing bug, a manipulable oracle or a missed edge case in liquidation logic can be exploited within a single block, and there is rarely a way to reverse the damage.
We engineer DeFi systems for teams that treat that risk seriously. Protocol mechanics are modeled before they are coded, economic edge cases are tested under stress, and interfaces show users clearly what a transaction will do before they sign it.
Applications métier
- 01
Lending and collateral systems
Overcollateralized lending markets with configurable risk parameters, health-factor calculations and liquidation mechanics, tested against price shocks, oracle delays and thin-market conditions before any deployment to a public network.
- 02
Exchange mechanisms
Automated market maker, order-book and request-for-quote designs, including extensions to existing venues through mechanisms such as Uniswap v4 hooks, with explicit handling of slippage, front-running exposure and fee accounting.
- 03
Vault and treasury contracts
ERC-4626 tokenized vaults with clear accounting, deposit and withdrawal limits, and guarded adapters, engineered so that share pricing cannot be manipulated through donation, inflation or rounding attacks.
- 04
Protocol interfaces and dashboards
Web interfaces, transaction simulation and indexed dashboards that let users and operators see positions, protocol health and parameter changes as they happen, with human-readable previews before anyone signs.
Approche d’ingénierie
- 01
Mechanism modeling
We model protocol mechanics and incentives in Python or agent-based simulations to find unstable parameters, insolvency paths and manipulation opportunities before writing contract code.
- 02
Oracle and dependency design
Price feeds, time-weighted averages, circuit breakers and fallback logic are designed explicitly. Every external dependency, whether oracle, bridge or token, is documented with its failure behavior.
- 03
Implementation and invariant testing
Contracts are built in Foundry with invariant suites asserting solvency and accounting properties, and fork tests run against real mainnet state to expose integration surprises early.
- 04
Operational controls
Pause guardians, rate limits, timelocked governance and multisig administration are configured so operators can respond to incidents without holding unilateral control over user positions.
- 05
Audit and monitored launch
We support independent audits, help structure bug bounty programs, and launch with conservative limits plus on-chain monitoring and alerting through tools such as Tenderly, Forta or Hypernative.

Les questions des dirigeants
Can you guarantee our protocol will not be exploited?
No one can honestly offer that guarantee. What we provide is disciplined risk reduction: rigorous specification, adversarial testing, support for independent audits, conservative launch limits and active monitoring. We document residual risks plainly so your team and your users can make informed decisions.
Do you help with token launches or tokenomics?
We do not design token economics as a fundraising or market activity, and we do not participate in token sales or distributions. We engineer protocol mechanics and test their stability. Questions about issuance, distribution and regulatory classification belong with your legal counsel.
Will you operate or administer the protocol after launch?
No. Administrative keys, governance and operational authority remain with the client or its governance process. We can design multisig and timelock arrangements, write runbooks and train your team, but we do not hold keys that control user funds or protocol parameters.
