ShinzoToken.onBeforeTransfer(address,address,uint256) (#1023-1063) ignores return value by token.transferFrom(_yearWallet,address(this),walletBalance) (#1050)

Too many vulnerabilities (Unchecked transfer, Reentrancy vulnerability, etc.). High risk of a scam. DYOR & manual audit are advised.

Contract ownership is not renounced (belongs to a wallet)

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

ShinzoToken.onBeforeTransfer(address,address,uint256) (#1023-1063) uses timestamp for comparisons
Dangerous comparisons:

Dangerous comparisons:

Dangerous comparisons:

Dangerous comparisons:
