Chain Signatures 主网发布：NEAR 平台的开创性链抽象解决方案

今天，Chain Signatures 的官方主网发布标志着一个重要的里程碑，Chain Signatures 是在 NEAR 平台上开发的开创性链抽象解决方案。

Chain Signatures, a pioneering Chain Abstraction solution developed on the NEAR platform, has reached a significant milestone with its official Mainnet release. Following the successful completion of the testnet phase and a thorough security audit, developers can now integrate Chain Signatures’ omnichain capabilities into their decentralized applications (dApps) on Mainnet. This development also provides a fully chain abstracted user experience (UX) for end-users, including decentralized enthusiasts, through the initial cohort of Chain Signatures products that are now live on Mainnet.

Chain Signatures 是在 NEAR 平台上开发的开创性链抽象解决方案，随着其官方主网发布，已经达到了一个重要的里程碑。在成功完成测试网阶段和彻底的安全审核之后，开发人员现在可以将 Chain Signatures 的全链功能集成到主网上的去中心化应用程序 (dApp) 中。这一开发还通过目前在主网上上线的第一批 Chain Signatures 产品，为最终用户（包括去中心化爱好者）提供了完全链抽象的用户体验（UX）。

Built on a decentralized multi-party computation (MPC) network, Chain Signatures enables NEAR accounts to sign transactions across any blockchain protocol. It stands out as the sole MPC solution allowing smart contracts to sign transactions on any chain and for any number of accounts. This functionality is facilitated by the unique NEAR account model, where accounts are smart contracts by default.

Chain Signatures 建立在去中心化多方计算 (MPC) 网络之上，使 NEAR 账户能够跨任何区块链协议签署交易。它是唯一允许智能合约在任何链上为任意数量的账户签署交易的 MPC 解决方案。独特的 NEAR 账户模型促进了此功能，其中账户默认为智能合约。

This innovative solution simplifies the development of multichain dApps by reducing the complexity to a single layer: a smart contract on NEAR that communicates with all other chains. By abstracting away the intricacies and challenges of multichain dApps, Chain Signatures creates new opportunities for application design and user interfaces in the Web3 space. Unlike existing bridges or cross-chain messaging protocols, which often lack the ability to support all chains or scale efficiently, Chain Signatures can accommodate every blockchain without the need for native integration. This includes prominent chains like Ethereum, Bitcoin, the Cosmos ecosystem, and soon, Solana.

这种创新的解决方案通过将复杂性降低到单层来简化多链 dApp 的开发：NEAR 上与所有其他链进行通信的智能合约。通过抽象化多链 dApp 的复杂性和挑战，Chain Signatures 为 Web3 领域的应用程序设计和用户界面创造了新的机会。与现有的桥或跨链消息传递协议通常缺乏支持所有链或有效扩展的能力不同，链签名可以容纳每个区块链，而不需要本地集成。这包括以太坊、比特币、Cosmos 生态系统以及即将推出的 Solana 等著名区块链。

As of its launch, Chain Signatures Mainnet is already being utilized by five applications, collectively boasting over six million active users. Additionally, more than fifteen projects are actively developing using this technology. The ecosystem of Chain Signatures products is rapidly expanding, with applications spanning wallets, decentralized exchanges (DEXs), lending platforms, trading bots, bridges, and more.

自推出以来，Chain Signatures 主网已被五个应用程序使用，总共拥有超过 600 万活跃用户。此外，超过十五个项目正在积极使用该技术进行开发。 Chain Signatures 产品的生态系统正在迅速扩展，其应用程序涵盖钱包、去中心化交易所 (DEX)、借贷平台、交易机器人、桥接器等。

For instance, Sweat Wallet enables its 2.5 million active users on NEAR to bridge assets to and from any chain, starting with BNB and Base, while paying for gas in $SWEAT. Allstake has launched Phase 0 on NEAR, Solana, and Ethereum, supporting top Liquid Staking Tokens (LST) and Liquid Reward Tokens (LRT) protocols like LiNEAR Protocol, MetaPool, Marinade, Jito, Renzo, and EtherFi. HERE Wallet offers support for transactions on any chain through its mobile, web, and Telegram wallet platforms. Bitte Wallet provides passkey wallets for any chain, including Bitcoin, and facilitates connectivity to all Ethereum apps using WalletConnect. Lastly, Defuse operates as a truly multichain spot DEX, allowing for swift trading between assets on any chain.

例如，Sweat Wallet 使 NEAR 上的 250 万活跃用户能够从 BNB 和 Base 开始，在任何链之间桥接资产，同时用 SWEAT 支付 Gas 费用。 Allstake 已在 NEAR、Solana 和以太坊上启动第 0 阶段，支持顶级 Liquid 质押代币 (LST) 和 Liquid 奖励代币 (LRT) 协议，例如 LiNEAR Protocol、MetaPool、Marinade、Jito、Renzo 和 EtherFi。 HERE 钱包通过其移动、网络和 Telegram 钱包平台为任何链上的交易提供支持。 Bitte Wallet 为包括比特币在内的任何链提供密钥钱包，并使用 WalletConnect 促进与所有以太坊应用程序的连接。最后，Defuse 作为一个真正的多链现货 DEX 运行，允许任何链上的资产之间进行快速交易。

Contributors from Proximity Labs have highlighted the pivotal role of Chain Signatures in addressing interoperability challenges within the fragmented Web3 landscape. They have noted that this innovation simplifies the user experience, enables decentralized finance (DeFi) functionalities for blockchains that do not traditionally support smart contracts, and empowers developers to support all chains seamlessly. By eliminating the need for bridges, Chain Signatures significantly expands the liquidity and utility of assets across various blockchains, transforming how users and developers interact with decentralized finance and making it more accessible.

Proximity Labs 的贡献者强调了链签名在解决分散的 Web3 环境中的互操作性挑战方面的关键作用。他们指出，这项创新简化了用户体验，为传统上不支持智能合约的区块链提供了去中心化金融（DeFi）功能，并使开发人员能够无缝支持所有链。通过消除对桥梁的需求，链签名显着扩展了各个区块链上资产的流动性和效用，改变了用户和开发人员与去中心化金融的交互方式，并使其更容易获得。

A crucial component of the Chain Signatures stack is the Multichain Gas Relayer. This feature alleviates the burden of acquiring separate gas tokens for transactions on different chains by performing gas payments on the destination chain on behalf of the user. Users only need to pay the equivalent amount in an asset they already hold, such as NEAR or other NEAR-native fungible tokens like USDC or USDT. The combined power of Chain Signatures and the gas abstraction provided by the Multichain Gas Relayer offers a streamlined user experience, as exemplified by top dApps like Sweat Wallet.

链签名堆栈的一个重要组成部分是多链气体中继器。此功能通过代表用户在目标链上执行 Gas 支付，减轻了为不同链上的交易获取单独 Gas 代币的负担。用户只需支付他们已持有的资产的等值金额，例如 NEAR 或其他 NEAR 原生可替代代币，如 USDC 或 USDT。链签名和多链 Gas Relayer 提供的 Gas 抽象相结合，提供了简化的用户体验，Sweat Wallet 等顶级 dApp 就是例证。

Leadership from NEAR Foundation has expressed optimism that this development will replace fragmented liquidity in DeFi with a single DeFi layer for all chains. By removing the need for multiple wallets, manual bridging, and gas fee payments in various tokens, Chain Signatures makes all of DeFi accessible from wherever users are. This breakthrough is enabled by the ability of smart contracts to sign transactions for any blockchain, even Bitcoin, opening up new design spaces for financial applications in Web3.

NEAR 基金会的领导层表示乐观，认为这一发展将用适用于所有链的单一 DeFi 层取代 DeFi 中分散的流动性。通过消除对多个钱包、手动桥接和使用各种代币支付 Gas 费的需求，Chain Signatures 使用户无论身在何处都可以访问所有 DeFi。这一突破是通过智能合约为任何区块链（甚至是比特币）签署交易的能力实现的，为 Web3 中的金融应用程序开辟了新的设计空间。

The Chain Signatures Mainnet is secured by eight reputable validators, including Pagoda, Luganodes, The Lifted Initiative, InfStones, Staking4All, Node.Monster, Black Sand Technologies, and Aurora. The initial audit of the Chain Signatures protocol has been conducted by Kudelski, with the final report set to be published soon on the Chain Signatures GitHub.

Chain Signatures 主网由八个信誉良好的验证者提供保护，包括 Pagoda、Luganodes、The Lifted Initiative、InfStones、Stake4All、Node.Monster、Black Sand Technologies 和 Aurora。 Kudelski 对 Chain Signatures 协议进行了初步审核，最终报告将很快在 Chain Signatures GitHub 上发布。

Looking ahead, the development roadmap for Chain Signatures includes adding support for the EDDSA elliptic curve before the end of the year, which will expand compatibility to chains like Solana and TON. Additionally, the team aims to increase throughput to match NEAR’s sharded capacity, targeting up to 300 transactions per second. Over time, the number of validators on the network is expected to grow, with the goal of achieving 40+ highly independent nodes, requiring 27 for a single signature.

展望未来，Chain Signatures 的开发路线图包括在年底前增加对 EDDSA 椭圆曲线的支持，这将扩大对 Solana 和 TON 等链的兼容性。此外，该团队的目标是提高吞吐量以匹配 NEAR 的分片容量，目标是每秒处理高达 300 笔交易。随着时间的推移，网络上验证器的数量预计会增长，目标是实现 40 多个高度独立的节点，单个签名需要 27 个节点。
