BNB Chain Liquid Staking is Tranchess’s BNB Chain staking product centered on QUEEN, an asset tracker that earns delegation rewards for BNB and farms the CHESS governance token. QUEEN can be split into ROOK and BISHOP, with BISHOP eligible for AMM trading fees. The page states that the BNB, BTCB, and ETH funds are retired and instructs holders to unstake and redeem.
