+## Token holders
+
+This query returns all holders of a specific token with their balances. It aggregates transfers by receiver (holder) for the given token: each row is a wallet address that holds the token, with total received (`sum_in`), total sent (`sum_out`), and current balance (`sum_in - sum_out`). Results are sorted by balance descending and limited to the top 10,000 holders. Use `date: { since: "..." }` to compute balances from a given date onward.
+
+You can run the query [here](https://ide.bitquery.io/solana-holders_1).

 ## Token Transfers to a Specific Wallet (for Bubble Map)
 
 This query retrieves all incoming transfers of a specific token (e.g., USDT) to a given Solana wallet on a particular date. It includes sender and receiver details, transaction signatures, block data, and transfer amounts in USD — useful for visualizing wallet inflows using a Bubble Map.
