The Changer Protocol, centred around the Changer (CNG) ERC-20 token, is designed for trading across various networks and decentralised exchanges. It enhances price transparency in cryptocurrency exchanges and OTC markets. Key features include Changer Convert for streamlined token conversion across blockchains, and Changer Pro, an OTC aggregator for competitive pricing on major tokens. Changer Swap integrates with leading DEXs for optimal trading, initially on the Ethereum network, with plans for expansion. The CNG token is crucial to the ecosystem, used for staking, advertising, and as part of the liquidity pool in derivative DEXs. It supports a range of stablecoins and offers benefits like transaction fee reductions and rewards. Changer.io serves as a primary liquidity venue for CNG. In June 2021, the protocol was upgraded, changing the token ticker to CNG and reducing gas fees.
