Since user funds are deposited from external networks (Arbitrum) into the sovereign L1 blockchain, the bridge smart contract is the main attack vector. Below is the official registry of audit opinions confirming the reliability of the infrastructure, staking mechanisms and asset-protection systems.
The audit architecture: Zellic and Certora
Zellic (bridge-contract and staking-logic audit)
The key reviewing element of the Hyperliquid architecture was the leading Web3 cybersecurity company Zellic. Its specialists conducted a comprehensive audit of the Bridge2 smart contract on Arbitrum, which aggregates all user USDC stablecoins. The audit confirmed the absence of critical vulnerabilities in the deposit-handling logic and cryptographic signatures.
Certora and Nethermind (formal verification of the HyperEVM ecosystem)
While the HyperCore core is written in Rust, the EVM-compatible smart-contract environment (HyperEVM) and the key dApps deployed in it (such as Felix CDP, Hyperbeat and HypurrFi) undergo formal verification by Certora and Nethermind. This mathematically proves the correctness of code execution at the EVM level and protects user capital from logical errors.
Risk management (Fund Custody) and the bridge-protection mechanism
Unlike rollup networks (where data availability is guaranteed by an Ethereum contract), Hyperliquid is an independent blockchain. Bridge security rests on the Proof-of-Stake (PoS) consensus mechanism.
- Validator consensus (bridge security): deposits into the Arbitrum smart contract are credited to the Hyperliquid L1 after confirmation. Withdrawals from the bridge require valid cryptographic signatures from validators holding more than 2/3 (66%+) of the network's total staking power.
- Dispute window and cold-wallet signatures: the bridge architecture includes a special dispute window for transactions. If suspicious activity or a state mismatch is detected, the bridge can be halted. Unlocking it requires exclusively "cold-wallet signatures" from the same 2/3 of validators, protecting funds even if the nodes' hot keys are compromised.
Official security reports
The table below lists the confirmed security reports for the Hyperliquid infrastructure. The original documents are hosted in the official GitBook documentation and the auditors' GitHub repositories.
| Component / Protocol | Auditor | Vulnerability summary (TL;DR) | Original reports |
|---|---|---|---|
| Arbitrum Bridge2 Contract L1 Staking Logic & USDC Custody |
Zellic | Audited & Verified. No critical vulnerabilities found. The validator multisignature logic and bridge-state manipulation protection are implemented correctly. |

Education hub: auditing L1 app-chains
Interpreting audits of independent L1 blockchains (app-chains) such as Hyperliquid differs radically from reviewing classic AMMs (for example, Uniswap) or rollup networks. The main focus is consensus and bridge security.
Cross-chain bridge security
In the Hyperliquid architecture, your USDC deposits are held in a smart contract on Arbitrum. Auditors (such as Zellic) thoroughly verify that this contract has no backdoors and obeys strictly cryptographic rules — withdrawals only with a majority of L1 validator signatures.
Native oracles
The audits also analyze price-manipulation vectors. Hyperliquid does not use external oracle smart contracts. Network validators broadcast prices directly into the HyperBFT consensus, protecting the system from classic DeFi flash-loan attacks.
Real-time $HYPE token security monitoring
We strongly recommend investors use on-chain analytics platforms to track the security score of smart contracts. You can monitor GitHub repository activity and basic reliability metrics (on-chain monitoring) via CertiK Skynet tools.
