It is a functional professional ecosystem through Dorum Token for the exchange of exclusive author content (artists, influencers, content creators, models, social communicators, actors, architects, designers among other prominent profiles) linked and offered in its own NFT Marketplace, integrated towards a metaverse roadmap where the exhibition of works, art and in rooms located in our virtual museum highlight the exclusivity of each work exhibited there.

The ecosystem of DORUM Social Meta Network, NFT Marketplace, and Metaverse is tied to the ICO Token DORUM Coin.

dorum.addLiquidity(uint256,uint256) (#816-829) sends eth to arbitrary user
Dangerous calls:

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.
