Citrea is a ZK Rollup network leveraging Bitcoin as its data availability and settlement layers. By employing BitVM and Type-2 zkEVM technology, it delivers smart contract and BTCFi capabilities for BTC. Unlike traditional Bitcoin sidechains, Citrea emphasizes a "Bitcoin-native" architecture, seeking to enable BTC to support DeFi, stablecoins, lending, and on-chain financial applications without altering Bitcoin's consensus rules.

Citrea delivers Smart Contract and BTCFi capabilities for BTC through zkEVM, Zero-Knowledge Proof (ZK Proof), and BitVM. Unlike traditional Bitcoin sidechains, Citrea focuses on a "Bitcoin-native" architecture, with the goal of anchoring final security to the Bitcoin main chain. Citrea's rollup process consists of five stages: trade execution, state packing, ZK Proof generation, data submission, and Bitcoin verification. User trades are first executed on Layer2's zkEVM, after which the system generates state proofs and completes final verification and settlement through BitVM and Bitcoin.

Built on Sei — a Layer 1 blockchain purpose-built for trading — the Sei NFT Marketplace leverages its native Central Limit Order Book (CLOB) and parallelized engine to match tens of thousands of orders per second. This reduces NFT trade latency to mere milliseconds, minimizes trading fees, and eliminates intermediary order sniping and slippage.

Citrea and Stacks are both Bitcoin Layer2 solutions, but they differ significantly in underlying architecture and security mechanisms. Citrea uses ZK Rollup, BitVM, and Bitcoin Settlement to anchor final state security to Bitcoin, while Stacks employs an independent chain and PoX (Proof of Transfer) mechanism to provide Smart Contract functionality through its own network.

The ctUSD Vault serves as the core stablecoin liquidity module within the Citrea BTCFi ecosystem, delivering baseline liquidity to the Bitcoin DeFi Marketplace through stablecoin deposits, on-chain asset allocation, and CTR incentives. Its objective is to establish a more stable on-chain capital flow system within the Bitcoin Layer2 environment.
