+# DOS Chain token lists
+
+This directory contains the public Uniswap Token Lists consumed by DOScan
+backend deployments through `TOKEN_LIST_URL`.
+
+Blockscout does not ship per-chain token-list files. Each deployment owns and
+hosts its list at a stable HTTP(S) URL. Token icons belong in
+`configs/token-icons/` and each `logoURI` must use the canonical raw GitHub URL.
+
+## Adding a token
+
+1. Add a permanent SVG or PNG under `configs/token-icons/`.
+2. Add the token to the matching network JSON file.
+3. Use the checksummed contract address and exact chain ID.
+4. Increment the list version and timestamp.
+5. Confirm the contract and its on-chain metadata before merging.
