Bullet, evolving from Zeta Markets, is a specialized execution layer and network extension for Solana, designed to create a high-performance trading environment. It aims to be an ultra-fast, reliable decentralized exchange (DEX) built as a Solana L2 to avoid L1 congestion. The platform, which includes the Bullet Network and BulletX DEX, supports trading perpetuals with up to 100x leverage, spot trading, and borrow/lend functionalities from a single account with multi-collateral support. Security is emphasized through trustless transactions, ZK proofs for settlement on Solana L1, and advanced risk mechanisms. The native token, $BULLET (migrated 1:1 from $ZEX), is integral to the ecosystem, used for gas fees, node operations, and staking. The platform is currently in its testnet phase.
