If an exchange is missing from the CoinGecko listing, do refer to this guide to inform CoinGecko of exchanges trading new tokens.

Additionally, for certain decentralized exchanges, CoinGecko generalized some trading pairs. For example, all Uniswap v2 DEX trading pairs will be displayed on CoinGecko as trading only against /ETH. Our algorithm sums up all trading volume for the different trading pairs (/USDC, /ETH, etc) but just displays it as a single line item on the front-end.
