On-chain security analysis — is it a scam or legit?
PolygonThe ChildERC20 contract is a standard bridge-compatible token implementation on Polygon.
Read the full analysisEach 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
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.
Holder balances as recorded by the audit of Oct 22, 2026
The 20 remaining pairs hold $112.9K between them and are not listed. The 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.

Implement a function that allows the contract owner to withdraw any native assets accidentally sent to the contract address.
Unresolved
The deposit function allows addresses with the DEPOSITOR_ROLE to mint new tokens at will. This centralizes control over the total supply and could lead to significant holder dilution if the role is compromised.
Restrict the DEPOSITOR_ROLE to a multi-signature wallet or a time-locked contract to prevent unauthorized minting actions.
Unresolved
0.0% of the pool's LP is burned or time-locked. 91.2% is held, unlocked, by 10 address(es) other than the owner/deployer. One of them — a contract, 0x1151…72be — holds 56.0% and can remove that share at once; who controls it is not visible on-chain, so it is not treated as an independent provider. Some pools are concentrated-liquidity (V3/V4) positions; shares above are by position as GoPlus reports them. This assessment covers the main pool, which holds 22% of the token's DEX liquidity; the other pools were not assessed.
Check the lock's end date and beneficiary on the locker's own page before relying on it.
Acknowledged
The ten largest holders own 29.5% of supply. Of that, 5.5% in DEX pools — not holders that can sell, so excluded from the concentration score. What remains: 10.0% in wallets, 14.1% in other contracts. 107,799 holders in total.
Watch the largest wallets that are not exchanges, pools or locks — those are the ones that can move the price.

Acknowledged
The ChildERC20 contract is a standard bridge-compatible token implementation on Polygon. It utilizes OpenZeppelin's AccessControl for role management and supports meta-transactions. While the core ERC-20 logic is standard, the contract contains centralized minting capabilities and a lack of mechanisms to recover accidentally sent native assets.
The architecture follows established patterns for cross-chain tokens, utilizing 7.1 Architecture standards for bridge compatibility. 7.2 Code Security is robust, leveraging well-audited OpenZeppelin libraries for ERC-20 and AccessControl. 7.3 Access Control is correctly implemented using role-based permissions, though 7.6 External interactions are limited by the lack of native asset recovery.
7.4 Economic risks are present due to the minting authority granted to the DEPOSITOR_ROLE, which can impact token supply. 7.5 Governance is centralized, relying on the admin roles to manage bridge operations. The system is designed for bridge-specific utility rather than decentralized governance.
7.7 Upgrades are not supported as the contract is not a proxy. 7.8 Operations are stable, with no complex state transitions outside of standard mint/burn cycles.
The contract is functionally sound for its intended purpose as a bridge token.
It is recommended to implement a 'rescue' function to allow the owner to withdraw accidentally sent native tokens or ERC-20 tokens, addressing the trapped asset issue. Ensure that the private keys associated with the DEPOSITOR_ROLE are managed via a multi-signature wallet or a secure hardware security module to mitigate the risk of unauthorized minting.
