The Bitcoin Standard Hashrate project is underway, and liquidity only seems to exist on PancakeSwap so far. τBTC aims to be a synthetic BTC-pegged token that is not controlled by Binance. Other independent BTC bridge tokens akin to BTCB exist (pBTC, renBTC); but τBTC's peg mechanism is unique.
τBTC-BTC LP tokens are, in principle, a stablecoin pair; so they shouldn't incur much, if any, impermanent loss. Adding a farm for this pair to CafeSwap will encourage the use of τBTC and decentralize the BSC ecosystem a little more away from PancakeSwap. It will also bring BTC holders to the Café.
Furthermore, the only τBTC pair that exists with appreciable liquidity on PCS is τBTC-BTC. More avenues to swap into τBTC might be good to have. Perhaps it is worth considering also adding a BREW-τBTC LP farm.
