OMT Chat facilitates joint trading on a decentralized derivatives exchange with zero price impact. It's linked to the @omtchannel Telegram channel. Similar projects include Decentralized Exchange Wallet, offering a decentralized ecosystem with zero gas fees on its own BSC side chain and features like DEX, multi-chain support, staking, launchpad, and an NFT marketplace. INME SWAP is another similar platform enabling storage, sending, receiving, and exchange of tokens without third-party interference. Both projects emphasize decentralization and aim to provide a secure trading environment.
