Settings

You can customize the application by adding any of the following settings to your settings.env file in the root directory of this repo:

Name Default Description
SYMBOLS btc,eth The asset symbols you want to track.
CURRENCY usd The currency used to show asset prices. CoinGecko currently supports "usd" and "eur", while CoinMarketCap supports only "usd".
API coingecko The API you want to use to fetch price data. Currently supported APIs are "coingecko" and "coinmarketcap".
REFRESH_RATE 300 How often to refresh price data, in seconds.
SLEEP 3 How long each asset price displays before rotating, in seconds.
CMC_API_KEY The CoinMarketCap API key, required if you specified API=coinmarketcap.
SANDBOX Used for CoinMarketCap only. Set SANDBOX=false if you're developing and want to use the sandbox API.

Example:

SYMBOLS=btc,eth,ltc,xrp
API=coingecko

Note: Some symbols are ambiguous. For example, uni currently corresponds to three different currencies in the CoinGecko API. To specify the currency or token you want (with CoinGecko only), you can use the following:

SYMBOLS=btc,eth,uni:uniswap

The second value (uniswap) corresponds to the ID of the currency in the API. This is currently only supported for the CoinGecko API. You can find the CoinGecko ID for a token in the URL. E.g. https://www.coingecko.com/en/coins/uniswap.
