Coinbase Asset has published a link to its asset listing guidelines detailing the platform's asset review criteria. According to the document, the minimum requirement for an asset to list on the Coinbase Exchange is to obtain trading approval from the Coinbase Digital Asset Review Board (DASG), but about 90% of assets fail to meet its listing criteria. Even with DASG approval, there are other factors that need to be taken into account, including the track record and active level of the team; whether the project is partnering with a reliable liquidity provider; whether it supports a standard-compliant token protocol (e.g. ERC20, SPL, ARC20) or is an unsupported native blockchain asset. For native blockchain assets, the integration is relatively more difficult and may take longer for technical integration.
