Background PulseChain is a community-driven and energy-efficient POS blockchain which is a full-state fork of Ethereum, designed to empower developers, investors, and users. The Vouch team is excited to have delivered a decentralized LSD platform to Pulsechain uses as this supports the deeply held ethos and importance the user community places on DeFi solutions. Vouch Liquid Staking unlocks Pulsechain block rewards without running a Validator. The platform connects node operators and PLS stakers, enabling everyone to participate and earn yield. Keep your capital liquid, and experience the freedom of Vouch Liquid Staking. What is ETH LSD Stack ETH LSD Stack is a complex system based on Ethereum, designed to provide a comprehensive set of solutions related to Eth2.0 validator deposits, network fee management, proposal voting, and the storage and withdrawal of funds for users and nodes. The core part of ETH LSD Stack is a set of smart contracts, which are divided into two parts: the PlatformContract, a platform contract managed by 61 Lab, and the ProjectContracts, which belong to different projects. Platform contracts are common dependencies for all projects. Via platform contracts, developers or start-up projects can easily deploy and initialize their contract groups, distribute staking rewards. Core contracts: LsdToken: an ERC-20 compatible derived token. Users receive this token when depositing ETH to UserDeposit and burn it when unstaking. NodeDeposit: register node and call ETH official deposit contract UserDeposit: a pool user deposits in, will be used by node NetworkProposal: voters submit proposal and execute corresponding action NetworkWithdraw: distribute rewards to parties Core roles: Voter: privileged to propose changes to the on-chain status Node: an account manages its validators and receives rewards Understanding More: https://docs.stafi.io/lsaas/architecture_eth_lsd/ Growing Within the LSaaS StaFi's LSaaS goes beyond providing a service—it's about fostering growth alongside ecosystem partners. StaFi supports the operation of vPLS trust validators, while vPLS has also formed a native partnership with PulseChain's wallet provider to further mutual innovation and development. https://x.com/StaFi_Protocol/status/1861373868524610015 https://x.com/ThePulseWallet/status/1868533288610214014 Insights from Vouch Here’s what PlseChain community contributor, Jexxa from Vouch, had to say about the significance of vPLS launch : The Vouch team is thrilled to introduce Liquid Staking to the Pulsechain community, made possible by our collaborative effort with the StaFi team. Achieving a Mainnet launch in mere months is a testament to the dedication and expertise of both teams. This milestone marks the beginning of a promising relationship between the StaFi and Pulsechain communities, and we look forward to exploring new opportunities together. About StaFi StaFi is a leading Liquid Staking infrastructure provider and protocol for PoS chains. Its Liquid Staking as a Service (LSaaS) framework enables developers to create Liquid Staking Tokens (LSTs) and Liquid Re-staking Tokens (LRTs) across ecosystems like ETH, EVM, BTC, CosmWasm, and SOL. By issuing rTokens (e.g., rETH, rMATIC, rBNB), StaFi unlocks the liquidity of staked assets, allowing users to earn staking rewards while retaining the flexibility to engage in DeFi. With support for major blockchains such as Ethereum, Solana, Polygon, BNB Chain, and Cosmos, StaFi bridges liquidity and security in Proof-of-Stake networks.
