what's Serai DEX?

Serai is a decentralized exchange (DEX) built for seamless cross-chain asset swaps, initially supporting Bitcoin, Ethereum, DAI stablecoin, Monero, and more. It employs liquidity pools where users can trade or provide liquidity to earn fees, secured by a network of decentralized nodes using threshold multisignatures and collateralized wallets. Constructed entirely in Rust with no admin keys or central authority, Serai prioritizes privacy, security, and usability, enabling private swaps involving privacy coins like Monero without custody risks. The protocol leverages advanced cryptography for chain-agnostic operations, including FROST threshold signatures and economic security models. Nodes validate and execute trades across heterogeneous blockchains, offering improved capital efficiency and user experience over atomic swaps or centralized services. Serai remains fully open-source, with ongoing audits and development toward mainnet launch.
