ChainCatcher news, Bitcoin-based stablecoin protocol BSD has officially launched the Dual Stacking feature. Users who lock sBTC collateral in the BSD Vault can now simultaneously earn a 5% sBTC annualized yield. This means the same collateral can serve two roles at once: securing the user's credit line and earning Bitcoin yield. The Vault will begin generating yield in the next Stacking cycle (around December 3), with the first batch of yield expected to be distributed around December 17. According to BSD officials, the protocol's minimum annualized borrowing rate is currently 0%. The borrowing cost for some Vaults is about 0.1%, and after earning a 5% yield on collateral, users' net borrowing cost can drop to -4.9%, meaning users are effectively paid to borrow.
