The HypERC20 contract is an upgradeable cross-chain token bridge implementation. It utilizes a standard proxy pattern and integrates with an external mailbox system for interchain messaging. While the architecture follows established patterns for cross-chain interoperability, the implementation contains high-severity issues regarding state management and function modifiers that require immediate remediation.

Exact factors
- Mintable supply — no cap found, dilution unbounded; held by mailbox: Multisig
- Upgradeable proxy — the admin can replace the logic; admin: ProxyAdmin -> Multisig
- Liquidity NOT locked (100% of the pool; this pool is 99% of DEX liquidity) — held by independent providers — market-depth risk
- Code: Missing Payable Modifier (High, static analysis)
- Code: State Variable Shadowing (High, static analysis)
Each factor is an on-chain fact recorded at the time of this analysis. The score is computed from them by a deterministic function, so the same contract returns the same score for anyone who runs the audit. How scores are computed

How holder types affect the score
Share held by contracts — treasury, vesting, bridge or staking — is discounted against share held by wallets when the score is computed: a contract cannot decide to sell the way an anonymous holder can, though it can still be drained or voted to sell. Effective concentration is the figure the risk score is actually calculated from.

Liquidity
as of audit · Oct 20The risk score reads depth across every pair.
The LP tokens of the analysed pool are not locked or burned, so whoever holds them can withdraw that liquidity.

Security Findings
HighMissing Payable Modifier
The _dispatch function is marked as nonpayable but is intended to handle native currency transfers. This will cause transactions to revert if they include a msg.value.CD-01
Issue
The _dispatch function is marked as nonpayable but is intended to handle native currency transfers. This will cause transactions to revert if they include a msg.value.
Fix
Add the 'payable' modifier to the _dispatch function to correctly handle native currency transfers.
Status
Unresolved
HighState Variable Shadowing
The contract contains instances of state variable shadowing, where local or inherited variables hide state variables of the same name. This can lead to unexpected behavior and logic errors during execution.CD-02
Issue
The contract contains instances of state variable shadowing, where local or inherited variables hide state variables of the same name. This can lead to unexpected behavior and logic errors during execution.
Fix
Rename shadowed variables to ensure clarity and prevent accidental modification of the wrong state variables.

MediumPrivileged Minting Capability
The functions transferRemote and handle allow for the creation of new tokens. This increases the total supply and dilutes existing holders, which is a significant economic risk if the mailbox or remote router is compromised.CP-01
Issue
The functions transferRemote and handle allow for the creation of new tokens. This increases the total supply and dilutes existing holders, which is a significant economic risk if the mailbox or remote router is compromised.
Fix
Implement strict validation on the origin of minting requests and consider adding a hard cap on the total supply that can be minted via the bridge.

0.0% of the pool's LP is burned or time-locked. 100.0% is held, unlocked, by 2 address(es) other than the owner/deployer. One of them — a wallet, 0xc324…5cab — holds 72.7% and can remove that share at once; who controls it is not visible on-chain, so it is not treated as an independent provider.

InfoWho holds the supply
The ten largest holders own 91.0% of supply. Of that, 56.8% in DEX pools — not holders that can sell, so excluded from the concentration score. What remains: 0.9% in wallets, 33.3% in other contracts. 17,733 holders in total.QA-HOLDERS

Analysis
AI Copilotas of audit · Oct 20The architecture leverages a robust modular design for cross-chain communication via the Mailbox pattern. 7.1 Architecture is well-structured for scalability, and 7.2 Code Security is generally high, though 7.3 Access Control contains critical flaws. Specifically, the use of nonpayable functions for value-transfer operations and state shadowing present significant risks to contract stability.
7.4 Economic and 7.5 Governance risks are centered on the minting capabilities inherent in the bridge mechanism. The ability to mint tokens via the handle function allows for potential supply inflation if the mailbox or remote router is compromised. Governance is currently centralized under a 3-of-5 multisig, providing a reasonable balance between security and operational agility.
7.7 Upgrades are managed via a Transparent Proxy pattern with a dedicated ProxyAdmin. This setup is industry-standard and allows for secure, controlled updates to the implementation logic. 7.8 Operations are supported by clear administrative functions for enrolling remote routers and configuring gas parameters.
Immediate remediation of the high-severity findings is required before further deployment or scaling.
Specifically, ensure all functions handling native currency are marked as payable and resolve all state variable shadowing to prevent logic errors. It is recommended to implement a circuit breaker or pause mechanism that can be triggered by the multisig in the event of a detected anomaly in the cross-chain messaging layer. Regular monitoring of the mailbox and remote router configurations is essential to ensure the integrity of the minting process.
