Dune tracks USD prices from coinpaprika and coingecko. If you want to add an asset to prices.usd or prices.layer1_usd follow these steps and open a PR:

1. Find the asset on coinpaprika. Note the symbol
2. Note the ID of the asset from coinpaprikas URL. In https://coinpaprika.com/coin/dmg-dmm-governance/ dmg-dmm-governance is the ID.
3. If the asset is a token on Ethereum, find the contract address and number of decimals e.g. through etherscan.
4. The last step is to add an entry to prices/ethereum/coinpaprika.yaml with the following format (Without comments)

- name: dmg_dmm_governance id: dmg-dmm-governance # the id from above symbol: DMG # the asset ticker address: 0xdeadbeef # the contract address decimals: 18 # the number of decimals the token contract uses

When the PR is merged we will deploy the changes and you will soon see USD prices for your asset.

1. Find the asset on coingecko.
2. Go the page for the given coin. Under the Info section there should be a field called API id. This it the id
3. The last step is to add an entry to prices/polygon/coingecko.yaml with the following format (Without comments)

- id: dmg-dmm-governance # the id from above

NOTE: For coingecko only the id is required. All other fields will be generated when the feed begins.
