Bullet

Bullet is a high-performance trading infrastructure layer built by the team behind Zeta Markets, positioned as Solana's first network extension purpose-built for trading. Rather than operating as a standalone chain, Bullet extends Solana's execution capacity through a dedicated application-specific runtime while anchoring final settlement to Solana L1 — preserving the security guarantees of Solana's validator network without requiring traders to migrate trust to a new, unproven consensus layer.

Background: From Zeta Markets to Bullet

Bullet was developed by the Zeta Markets team, a Solana-native perpetual futures exchange that processed over 628 million cumulative trades and $8 billion in all-time trading volume before initiating its transition into the Bullet network extension. The project was announced in 2024 and moved to public testnet in early 2025, with mainnet deployment targeted for Q2 2025. Zeta Markets co-founder Anmo cited the absence of a reliable, performant perpetuals DEX on Solana as the core motivation — a gap made stark by the fact that Hyperliquid, a competing layer-1 perps exchange, processed roughly six times more perpetual futures volume than all Solana-based DEXs combined at the time of Bullet's launch announcement.

Investors backing the Zeta Markets team include Jump Capital, Electric Capital, Race Capital, Wintermute, Amber, the Solana Foundation, Sino Global, and QCP Capital.

Architecture: A Modular Execution Layer on Solana

Bullet's architecture consists of four modular components that work together to deliver low latency while inheriting Solana's security model.

Execution layer. Bullet Core is a purely Rust-based execution environment built using the Sovereign SDK. At its center is a centralized sequencer that orders and executes transactions in real time, issuing soft confirmations within 1 millisecond — compared to the 400ms-plus latency typical of applications running directly on Solana L1. The sequencer enforces custom ordering rules specifically designed for trading: maker orders and cancellations are prioritized over taker orders, reducing MEV exposure for liquidity providers.

Settlement. Despite having its own execution environment, Bullet settles transactions on Solana L1, anchoring finality to Solana's validator set rather than a new or permissioned set of nodes. Hard finality is reached in 5–12 seconds.

Data availability. Transaction data is published through Celestia, which supports throughput of up to 27 MB/s, significantly reducing costs compared to posting all data directly on L1.

Cryptographic verification. Succinct Labs' SP1 zkVM generates zero-knowledge proofs of execution that are posted to Solana L1, providing cryptographic evidence of transaction validity without requiring trust in the sequencer alone.

This combination gives Bullet a performance profile the team describes as 100 times faster than Solana and 40 times faster than Hyperliquid for order confirmation latency, while retaining access to Solana's approximately 1,000-node validator network for settlement security.

Performance Specifications

• 1 millisecond soft confirmation latency
• 8,000+ exchange orders per second
• 5–12 seconds hard finality on Solana L1
• Oracle price updates via Pyth Lazer at 1ms frequency
• 400x latency improvement compared to L1-native DEXs

Trading Products

Bullet is designed as an integrated trading environment covering three core DeFi primitives within a single account and margin system.

Perpetual futures. The flagship product supports up to 100x leverage across 100+ trading markets. Collateral is managed in a cross-margin system, and multi-collateral support includes USDC and other major assets. Funding rates are charged hourly using a fixed interest rate plus a premium index component. Available order types include limit (GTC), Fill-or-Kill, Immediate-or-Cancel, Post-Only variants, and conditional orders such as Take Profit and Stop Loss.

Spot trading. Direct asset ownership with margin trading capabilities.

Lending and borrowing. An algorithmic interest rate model using a piecewise function based on asset utilization rates governs borrow costs.

Risk management. The platform monitors initial and maintenance margin thresholds in real time, automatically cancelling orders when a margin violation is detected. Larger positions are handled by a Community Liquidation Vault. Final backstops include a USDC-denominated Insurance Fund and an Auto-Deleveraging system.

User Experience and Onboarding

Bullet integrates wallet abstraction through Privy, allowing users to log in with social credentials and use session keys without manually signing every transaction. Gas abstraction via a paymaster removes the need for users to hold gas tokens to trade. Native Solana wallets — Phantom, Solflare, and Backpack — are supported directly, with EVM wallet support (MetaMask, Rabby) on the roadmap.

Cross-chain deposits are handled through Hyperlane for multi-chain bridging and Relay Protocol for near-instant intent-based bridging.

Token: $BULLET

The $ZEX token, originally issued by Zeta Markets, is migrating to $BULLET on a 1:1 basis with no dilution for existing holders. $BULLET is designed as a network token with multiple utility functions: paying gas fees on the Bullet network, operating nodes, staking, and participating in governance of the exchange layer. The migration preserves the existing community stake in the network.

Future Roadmap: BulletSVM

The team has outlined a permissionless deployment layer called BulletSVM, analogous to Hyperliquid's HyperEVM. This would allow third-party protocols and applications to build on top of Bullet's matching engine and liquidity pool via pre-compiled interfaces, potentially expanding Bullet from a single DEX into a composable trading infrastructure platform.

Solana Ecosystem Context

Bullet represents one of the most technically ambitious bets on Solana's infrastructure to date: that combining a purpose-built sequencer with ZK-verified settlement on L1 can close the performance gap between decentralized exchanges and centralized ones, without sacrificing Solana's decentralization or requiring a liquidity cold start on a new chain. Its direct competitive reference point is Hyperliquid, which operates as an isolated L1 with a 21-node permissioned validator set. Bullet's approach trades raw throughput (Hyperliquid claims 200,000 orders per second versus Bullet's 8,000+) for a smaller trust surface, broader validator participation, and tighter integration with Solana's existing liquidity and user base.

Zeta Markets' three-plus years of exploit-free operation on Solana — across a period that included multiple high-profile DeFi exploits across the industry — provides meaningful evidence of the team's security discipline as they scale to this more complex architecture.
