Prevent hacks before they happen.
That's the north star for our product, the Credible Layer.
More than $2B has been stolen in hacks already in 2025.
You have public code. There are a million attack vectors. All you're trying to prevent: lost funds.
Current DeFi security relies on three approaches: audits, static analysis, and AI monitoring.
All three have fundamental limitations that leave protocols wanting more.
Audits are snapshots - they only see your code as it exists on audit day. They can't protect against non-technical vulnerabilities like governance attacks or oracle manipulation, and they miss runtime-specific issues. Worse, competitive audits and bug bounties create race conditions between whitehats and blackhats - not a dependable form of security.
Static analysis can't model runtime conditions or novel attacks. You'd have to define everything to model everything, which is impossible. Advanced tools require significant time and technical expertise - months of work with custom languages that only tier-1 protocols can afford.
AI monitoring kills app UX with false positives due to the probabilistic nature of these tools. You have to trust their uptime and security since they run the models protecting your users' funds. And transparency is hard to attain because heuristic models aren't publicly available - requiring more trust, not less.
The best security today looks like Swiss cheese. But...
You Shouldn't Have to Make These Tradeoffs
We've been building something for 2 years to solve this.
The Credible Layer is network-native security: apps write rules in Solidity, the sequencer enforces them during block building, dropping any transaction that violates those rules.
How It Works
Developers write security rules (assertions) that define what should never happen to their protocol. These assertions are validated against every transaction by the network itself - integrated directly into the sequencer as a sidecar.
End users submit transactions as normal. The Credible Layer validates each transaction against active assertions.
Valid transactions proceed to the finalized block. Invalid transactions are rejected before execution.
Inescapable, Rule-Based Security
- The network removes every transaction that violates your rules during sequencing.
- Sequencer-level enforcement means attacks can't be bypassed with private mempools like AI tools can.
- Zero false positives because we use deterministic rules, not probabilistic guessing.
- No race conditions - we prevent before execution rather than trying to frontrun attackers.
- And 24/7 protection that runs at the network level without depending on external services staying online.
Easy to Use
- Written in Solidity with Foundry-like syntax - your team already knows how to write assertions.
- No contract modifications needed because assertions live outside your protocol code.
- Go live in 20 minutes, not the months-long timeline of formal verification.
- Deploy and update instantly without audits or contract upgrades.
- You can even reuse proven assertions by forking security rules from similar protocols.
Verifiable and Transparent
- All rules are public onchain - users can inspect exactly what protects their funds.
- No black box AI - every rule is auditable Solidity code anyone can verify onchain.
- The network enforces your rules, so there's no trusting third-party uptime or security.
- And you build trust faster because integrating protocols can quickly assess your security posture.
GMX lost $50mm. Radiant lost $42mm. Euler lost over $200mm. Cream Finance lost $130mm. Bybit lost $1.4B. Compound lost $160mm.
Simple assertions defining protocol invariants would have removed these hacks during sequencing.
Institutions are ready to deploy capital into DeFi, but security risk is the #1 barrier. 184 TradFi organizations cite "perceived risks (e.g., security, volatility)" as their top concern about blockchain involvement.
Meanwhile, real capital is moving: Morpho was chosen for $GAME's ETH treasury yield strategy with up to $250M approved for allocation. SharpLink is exploring staking a portion of its $3.6 billion Ethereum treasury on Linea.
The missing piece, the last piece, is security.
See how our devrel @_czepluch demonstrates how a recent hack could have been prevented with an assertion.
Abracadabra got hit for $1.8M in the weekend. Their third hack in 2 years.
The bug? A logic flaw in cook() let attackers borrow without collateral by manipulating a status flag with a 2-action sequence.
The contracts were supposed to be "deprecated".
