57# BTC markets: donation APY to 1.80% and releverage fee to 120 bps (after Curve vote 1494)

Set the yb-WBTC (market 7), yb-cbBTC (market 8) and yb-tBTC (market 9) donation APY to 1.80% per year on crvUSD - which at 2x leverage corresponds to a 0.90% donation APY at the Curve pool level - and their releverage fee to 120 bps (1.20%), down from 2.64% and 182 bps. These parameters belong together with the new crvUSD/WBTC, crvUSD/cbBTC and crvUSD/tBTC pool parameters and fee policies installed by Curve ownership vote 1494, so this proposal is guarded: it first asserts that each of the three pools already runs the policy contract that vote 1494 installs, and reverts otherwise. It therefore cannot take effect before the Curve vote is executed, and can simply be executed once that has happened.
