Bitcoin Dollar (BTCD) is a decentralized finance protocol deployed on Ethereum mainnet. The protocol issues BTCD, a token structured with a 50/50 exposure to BTC and USD, designed to provide balanced exposure to both assets within a single instrument. sBTCD is the yield-bearing staked counterpart to BTCD, accruing returns through the protocol's underlying strategies. FISC is the protocol's governance token, which has not yet launched.

BTCD's core product infrastructure includes a USD Vault, which accepts USDC deposits and directs them into strategies designed to maintain BTC-neutral positioning. A Bitcoin Carry Vault, which would use BTC collateral to borrow stablecoins for deployment into yield-generating strategies, is in planning. A bdBTC Vault is currently in development.

The protocol uses Morpho's isolated lending markets as core infrastructure for its vault strategies. BTCD has received backing from Polygon Labs and Coinme. The protocol's primary yield sources are productive asset allocation across its BTC and USD-denominated positions, with supplementary returns available through volatility-based strategies during periods of market movement.

BTCD's stated purpose is to give users a mechanism for holding a balanced BTC/USD position while accessing yield generated from the underlying deployment of those assets, without requiring users to actively manage the rebalancing or yield strategies themselves.
