On-chain security analysis — is it a scam or legit?
The OptimismMintableERC20 contract is a standard ERC-20 token implementation designed for cross-chain bridging on the Base network.
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 26, 2026
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.
0xeddf…07bd0xadb1…c204No privileged address appears among these holders: the unlocked liquidity sits with independent providers, not with the deployer.
The mint(address,uint256) function allows a privileged bridge address to create new tokens at will. This increases the total supply and dilutes the value of existing holdings.
Ensure the bridge contract is secured by a multi-signature wallet or a decentralized governance process to prevent unauthorized minting.
Unresolved
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, 0xeddf…07bd — holds 81.2% 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 72% of the token's DEX liquidity; the other pools were not assessed.

The ten largest holders own 92.7% of supply. What remains: 5.0% in wallets, 87.7% in other contracts. 1,609 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 OptimismMintableERC20 contract is a standard ERC-20 token implementation designed for cross-chain bridging on the Base network. The architecture relies on a bridge-controlled minting mechanism, which is standard for L2 canonical tokens. The code is clean and follows established OpenZeppelin patterns, though the centralization of minting power remains a structural risk.
The contract utilizes robust, battle-tested OpenZeppelin libraries for ERC-20 functionality. 7.1 Architecture is modular, separating token logic from bridge-specific minting requirements. 7.2 Code Security is high due to the use of modern Solidity 0.8.x, which includes built-in overflow protection. 7.3 Access Control is strictly enforced via the onlyBridge modifier, ensuring only authorized bridge contracts can trigger minting.
7.4 Economic risk is primarily driven by the minting capability of the bridge. While necessary for cross-chain functionality, it introduces potential supply inflation if the bridge contract is compromised. 7.5 Governance is implicit, as the bridge contract acts as the sole authority for supply changes. 7.6 External dependencies are limited to the bridge, which is a trusted component of the L2 ecosystem.
7.7 Upgrades are not natively supported by this contract instance as it is not a proxy. 7.8 Operations are straightforward, relying on the standard bridge interaction flow. The lack of upgradeability ensures immutability of the current logic, which is a positive security trait.
The contract is well-implemented and follows standard practices for L2 token bridging.
No immediate code changes are required as the minting functionality is a core requirement for its intended purpose. Users and stakeholders should monitor the security of the bridge contract, as it is the single point of failure for token supply integrity. Ensure that the bridge contract's governance and access control mechanisms are audited and maintained to the highest standards.
