Adding a DexScreener Token

DexScreener is used for tokens that aren't listed on Pyth Network — Solana altcoins, pump.fun tokens, etc.

1. Get the pair address

Open any token's page on DexScreener and copy the pair part of the URL. The URL format is:

https://dexscreener.com/<chain>/<pair_address>
        e.g. https://dexscreener.com/solana/chvehkrbncdpdr1od9eya1vp635wwfdzgxdzexxt6v96

Here solana is the chain and chvehkrbncdpdr1od9eya1vp635wwfdzgxdzexxt6v96 is the pair address. You need both.

2. Add a bot token

DISCORD_TOKEN_CYB=your_cyb_bot_token_here

3. Add the pair to DEXSCREENER_FEEDS

Add an entry in the format TICKER:<chain>/<pair_address>:

DEXSCREENER_FEEDS=CYB:solana/chvehkrbncdpdr1od9eya1vp635wwfdzgxdzexxt6v96

Add multiple pairs by separating with commas:

DEXSCREENER_FEEDS=CYB:solana/<pair_address>,FOO:ethereum/<pair_address>

4. Rebuild

docker-compose up -d --build

The bot will automatically pick up the new ticker and start showing its price (including BTC/ETH/SOL conversions and charts, once it has collected enough history).
