What the internal review found

Scope: OldinToken, OldinLaunchFactory, deployment payload, access control, liquidity custody, fee accounting and local runtime behavior.

R-01 · MEDIUM · RESOLVED

Fee-claim denial by ETH recipient

Fees now remain WETH and are transferred as tokens, so a contract that rejects native ETH cannot block both recipients.

R-02 · LOW · ACKNOWLEDGED

Predicted-pool launch denial

A hostile pre-created pool can make one launch attempt revert. The exact-price check prevents funds from entering it; retrying with a new salt creates a new address.

R-03 · LOW · DISCLOSED

Early limits are not sybil protection

Direct pool transfers are limited for one hour, but forwarding contracts can redistribute tokens. Oldin does not market this as bot protection.

R-04 · MEDIUM · UI MITIGATION

Atomic creator-buy slippage

The public Oldin flow does not submit atomic creator buys until it can supply a safe nonzero minimum output.

Independent review is still required.

This page documents an internal engineering review, not certification, formal verification or a third-party audit. External Uniswap and PancakeSwap contracts were not re-audited. Mainnet contracts and crypto assets can still fail or lose all value.
