DecentraWorld.setRecentTx(bool,address,uint256) (#922-930) uses timestamp for comparisons
Dangerous comparisons:
- txSettings.lastTx[_sender].add(txSettings.txcooldown) < block.timestamp (#923)
Avoid relying on block.timestamp.

Contract ticker ($DEWO) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Contract has 0% buy tax and 24% sell tax.
Taxes are suspiciously high (over 10%) and contract ownership is not renounced. Token has a high risk of becoming a honeypot.

Token has only one trading pair
