Black Hole Protocol is a decentralized, self-custodial privacy architecture deployed on the Base blockchain, addressing the lack of transaction confidentiality on public ledgers by integrating Account Abstraction (ERC-4337) with Zero-Knowledge proofs (ZK-SNARKs) to enable shielded, anonymous interactions without compromising usability or security.

The native $BLKH token (contract address implied via Base deployment) powers the protocol as its utility asset, facilitating gas abstraction for zk computations, staking for network security and governance votes on privacy parameter upgrades, and fee rebates for active participants.
