About

Black Hole Protocol is a decentralized, self-custodial privacy architecture deployed on the Base network. It addresses the inherent lack of transaction privacy on public blockchains by combining Account Abstraction (ERC-4337) with Zero-Knowledge proofs (ZK-SNARKs). The protocol functions as a cryptographic firewall between a user's identity and their assets. Unlike traditional interaction models where a single Externally Owned Account (EOA) exposes a user's entire history and net worth, Black Hole utilizes a "Shielded Pool" for ingress and a novel "Balance Sharding" mechanism for storage. This architecture allows users to interact with DeFi applications and execute payments without leaking metadata or exposing their total holdings. .
