Trust & diligence
We coordinate audit and code review with recognised third-party firms your stakeholders, listing partners, and TVL providers already trust - a critical signal for protocol launches, exchange integrations, and institutional capital allocation.
Third-party names and marks belong to their respective owners.
Partner with us
DeFi protocols don't get second chances. A single oracle manipulation drains a lending pool. A liquidation engine that fails under stress accumulates bad debt your treasury can't cover. A reentrancy bug in a vault becomes a $50M post-mortem on Twitter. We build for teams who understand that DeFi is financial infrastructure - with invariant testing, formal verification where it matters, and operational playbooks that assume adversarial conditions from day one.
Why Bitronix
Not a feature list. Six specific reasons protocol founders and treasury teams choose Bitronix for DeFi programmes that must stay solvent under stress and credible to institutional capital.
Every protocol we build ships with a documented solvency model - what must be true for the protocol to remain solvent under every condition we can simulate. We don't ship code that doesn't have a corresponding invariant proof. Bad debt scenarios are designed for, not discovered after.
We don't test the happy path. We test against the attacker - oracle manipulation, sandwich attacks, donation attacks, reentrancy through hook callbacks, governance attacks. Every protocol survives our adversarial suite before it gets near an auditor.
You see every architectural decision, every test result, and every threat model output as we build. Your treasury, risk, and investor relations teams get a live documentation trail they can review at any phase - and hand to allocators during diligence.
We deploy across Ethereum, Arbitrum, Optimism, Base, Polygon, and Solana - with explicit risk modelling for each chain's bridge assumptions, oracle availability, and finality characteristics. Cross-chain isn't a deployment afterthought; it's a risk parameter.
Most firms ship and disappear. We provide on-chain monitoring with Forta, oracle health tracking, parameter governance support, and incident response with defined SLAs - because DeFi protocols don't have launch days, they have operational lifetimes.
Our case studies are public, our tech stacks are listed, and our audit partners are named. Read the architecture, check the chains, verify the firms. We give you the evidence to decide, not asks to trust.
Security & testing methodology
Most DeFi exploits - oracle manipulation, reentrancy, governance capture, liquidation cascades - are preventable with disciplined engineering. We engineer the preventable ones out so your protocol earns capital, not headlines.
Before contract code is written, we model what solvency means for your protocol under every condition: collateral value crashes, liquidation cascades, oracle delays, bridge failures. Solvency conditions are documented as mathematical invariants - not as intentions in a narrative deck alone.
We document every privileged role, every oracle dependency, every external call, every flash-loanable invariant. Attack surfaces specific to DeFi - sandwich attacks, donation attacks, governance capture, MEV extraction - are mapped before production code lands.
Solvency invariants, monotonicity properties, and conservation laws are encoded and tested via Echidna and Foundry fuzzing across millions of paths. Critical math is differentially tested against reference implementations and Python or Rust models.
Every protocol is stress-tested against historical exploit patterns: bZx-style oracle manipulation, Cream-style donation attacks, Mango-style governance capture, Euler-style donation reentrancy. If a published attack pattern works on your protocol, we find it before an auditor or attacker does.
For high-value invariants - solvency bounds, total supply conservation, liquidation correctness - we apply Certora or Halmos where it materially reduces residual uncertainty. We don't apply formal verification everywhere; we apply it where passing unit tests alone would be misleading for financial guarantees.
Every engagement produces a structured handoff: natspec-complete code, documented invariants with proofs, test coverage reports, adversarial simulation outputs, oracle configuration documentation, and a threat model your auditors can diligence end to end.
Our methodology is available to review before you engage.

Learn moreExecution model
No handoffs that lose context. The team that scopes your DeFi programme ships it and supports it post-launch. Every phase produces a defined artifact - nothing moves forward without it.
Timeline: 3–5 business days
Protocol mechanics, risk parameters, asset support, oracle strategy, and target chains mapped before architecture decisions.
Timeline: 2–4 weeks
Contract structure, role hierarchies, oracle dependencies, liquidation mechanics, and solvency invariants documented. Risk parameters modelled against adversarial conditions.
Timeline: 4–12 weeks depending on scope
Protocol contracts built against the spec with continuous invariant testing, fuzz campaigns, and adversarial simulation in CI.
Timeline: 3–8 weeks depending on audit firm availability
Contracts submitted to chosen firm; adversarial simulation re-run against final code; formal verification applied to critical invariants. Findings triaged and remediated through to sign-off.
Timeline: 1–2 weeks
Deterministic multi-chain deployment, parameter governance ceremony, oracle configuration, monitoring activation, and bug bounty programme launch.
Timeline: Ongoing - retainer or per-incident
On-chain monitoring, oracle health tracking, parameter governance support, and incident response under defined SLAs.
Timelines assume responsive client feedback at phase gates. Audit firm availability and formal verification scheduling are typically the pacing items - reserve audit slots 6–8 weeks in advance of your target launch date. Bug bounty platform onboarding (Immunefi, Code4rena) often runs in parallel with audit and should be initiated during Phase 4.

FAQ
Straight answers for protocol founders, treasury teams, and procurement - before you enter diligence.
Solvency modelling is the first deliverable on every DeFi engagement, not a side artefact. Before contract code is written, we document what solvency means for your specific protocol - the mathematical conditions that must hold for the protocol to remain solvent under every adversarial scenario we can simulate. For lending markets, that's collateral coverage under price shocks, liquidation efficiency, and bad-debt absorption paths. For AMMs, it's invariant preservation under donation attacks and rounding edge cases. For perpetuals, it's funding rate convergence and insurance fund adequacy under cascading liquidations. These conditions are encoded as on-chain invariants tested via Echidna and Foundry fuzzing - and where the cost of failure justifies it, formally verified via Certora or Halmos. We pair this with adversarial simulation against historical exploit patterns: bZx-style oracle manipulation, Cream-style donation attacks, Mango-style governance capture, Euler-style donation reentrancy. If a published attack pattern works on your protocol, we find it before an auditor or attacker does. We coordinate economic risk parameter modelling with firms like Gauntlet or Chaos Labs when scale and complexity warrant - but the engineering invariants are non-negotiable on every engagement.
AMMs (constant product, stable, concentrated liquidity), lending and perpetuals, vaults and aggregators, liquid staking interfaces, stablecoin cores, oracle aggregation, and cross-chain messaging integrations. We ship across Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Chain, Avalanche, and Solana where your liquidity and security model allows - with explicit trade-offs documented before build.
We select oracle topology against manipulation cost, staleness tolerance, and failover paths: Chainlink, Pyth, RedStone, TWAPs, and hybrid aggregation with circuit breakers. Fallback and pause semantics are documented; heartbeat and deviation thresholds are tuned to asset liquidity.
Yes - batch auctions, commit-reveal flows, Flashbots-aware routing, and integrations with private RPC or auction venues where your product model supports them. We document residual MEV surface honestly after implementation.
We specify triggers, partial liquidations, auction types, keeper incentives, and bad-debt socialisation paths - then fuzz under volatility paths and oracle delay scenarios. Liquidation correctness is a first-class invariant, not an afterthought.
Core practice is contract and protocol engineering with documented parameter rationale. For large programmes we coordinate with economic risk partners (e.g. Gauntlet, Chaos Labs) for simulation-backed recommendations - your counsel and treasury own final numbers.
We ship the audit preparation pack, coordinate with your firm or our partner network, triage every finding, implement root-cause fixes, and add regression tests through sign-off. Formal verification is scoped to invariants where proof materially reduces uncertainty.
Yes - we align scope, severity rubrics, and disclosure timelines with Immunefi, Code4rena, or your preferred venue, typically starting during adversarial validation so findings flow into a single triage process.
Discovery through audit-ready core often runs 10–22 weeks depending on market count, oracle complexity, and formal verification depth. Core team: lead protocol engineer, security reviewer, DevOps for deploy and monitoring - scaled per scope.
Market designs, asset universe, target chains, oracle preferences, liquidation philosophy, governance model, intended listing or integration partners, and target launch window. We respond within one business day with a scoped recommendation.
