Gas404 Official is an experimental DN-404 token built on the BNB Chain. It's associated with a DEX ecosystem and features a 1:1 allocation for Blast L2 Dex. The project boasts its own DEX (gas404swap.org) with locked liquidity and audited/timelocked contracts. A privacy-focused team is behind the project, with a focus on fast CMC/CG listing and buyback/burn events. Similar projects include Gas404 Presale FL and WrappedGas404 Presale FL, both with their own DEXs and audited contracts. EcoChain is another related project focused on sustainable DeFi investments.
