Chain Signatures 主網發布：NEAR 平台的開創性鏈抽象解決方案

今天，Chain Signatures 的官方主網發布標誌著一個重要的里程碑，Chain Signatures 是在 NEAR 平台上開發的開創性鏈抽象解決方案。

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 平台上開發的開創性鏈抽象解決方案，隨著其官方主網發布，已經達到了一個重要的里程碑。在成功完成測試網階段和徹底的安全審核之後，開發人員現在可以將 Chain Signatures 的全鏈功能整合到主網上的去中心化應用程式 (dApp) 中。這項開發也透過目前在主網上上線的第一批 Chain Signatures 產品，為最終用戶（包括去中心化愛好者）提供了完全鏈抽象的用戶體驗（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運算 (MPC) 網路之上，使 NEAR 帳戶能夠在任何區塊鏈協議中簽署交易。它是唯一允許智能合約在任何鏈上為任意數量的帳戶簽署交易的 MPC 解決方案。獨特的 NEAR 帳戶模型促進了此功能，其中帳戶預設為智能合約。

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.

這種創新的解決方案透過將複雜性降低到單層來簡化多鏈 dApp 的開發：NEAR 上與所有其他鏈進行通訊的智慧合約。透過抽象化多鏈 dApp 的複雜性和挑戰，Chain Signatures 為 Web3 領域的應用程式設計和使用者介面創造了新的機會。與現有的橋接器或跨鏈訊息傳遞協議通常缺乏支援所有鏈或有效擴展的能力不同，鏈簽名可以容納每個區塊鏈，而不需要本地整合。這包括以太坊、比特幣、Cosmos 生態系統以及即將推出的 Solana 等著名區塊鏈。

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.

自推出以來，Chain Signatures 主網已被五個應用程式使用，總共擁有超過 600 萬活躍用戶。此外，超過十五個項目正在積極使用該技術進行開發。 Chain Signatures 產品的生態系統正在迅速擴展，其應用程式涵蓋錢包、去中心化交易所 (DEX)、借貸平台、交易機器人、橋接器等。

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 讓 NEAR 上的 250 萬活躍用戶能夠從 BNB 和 Base 開始，在任何鏈條之間橋接資產，同時用 SWEAT 支付 Gas 費用。 Allstake 已在 NEAR、Solana 和以太坊上啟動第 0 階段，支援頂級 Liquid 質押代幣 (LST) 和 Liquid 獎勵代幣 (LRT) 協議，例如 LiNEAR Protocol、MetaPool、Marinade、Jito、Renzo 和 EtherFi。 HERE 錢包透過其行動、網路和 Telegram 錢包平台為任何鏈上的交易提供支援。 Bitte Wallet 為包括比特幣在內的任何鏈提供金鑰錢包，並使用 WalletConnect 促進與所有以太坊應用程式的連接。最後，Defuse 作為一個真正的多鏈現貨 DEX 運行，允許任何鏈上的資產之間進行快速交易。

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 的貢獻者強調了鏈簽名在解決分散的 Web3 環境中的互通性挑戰方面的關鍵作用。他們指出，這項創新簡化了用戶體驗，為傳統上不支援智能合約的區塊鏈提供了去中心化金融（DeFi）功能，並使開發人員能夠無縫支援所有鏈。透過消除對橋樑的需求，鏈簽名顯著擴展了各個區塊鏈上資產的流動性和效用，改變了用戶和開發人員與去中心化金融的互動方式，並使其更容易獲得。

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.

鏈簽名堆疊的一個重要組成部分是多鏈氣體中繼器。此功能透過代表用戶在目標鏈上執行 Gas 支付，減輕了為不同鏈上的交易獲取單獨 Gas 代幣的負擔。用戶只需支付他們已持有的資產的等值金額，例如 NEAR 或其他 NEAR 原生可替代代幣，如 USDC 或 USDT。鏈簽名和多鏈 Gas Relayer 提供的 Gas 抽象相結合，提供了簡化的使用者體驗，Sweat Wallet 等頂級 dApp 就是例證。

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 基金會的領導階層表示樂觀，認為這項發展將以適用於所有鏈的單一 DeFi 層取代 DeFi 中分散的流動性。透過消除對多個錢包、手動橋接和使用各種代幣支付 Gas 費的需求，Chain Signatures 使用戶無論身在何處都可以存取所有 DeFi。這項突破是透過智慧合約為任何區塊鏈（甚至是比特幣）簽署交易的能力來實現的，為 Web3 中的金融應用程式開闢了新的設計空間。

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 主網由八個信譽良好的驗證者提供保護，包括 Pagoda、Luganodes、The Lifted Initiative、InfStones、Stake4All、Node.Monster、Black Sand Technologies 和 Aurora。 Kudelski 對 Chain Signatures 協議進行了初步審核，最終報告很快就會在 Chain Signatures GitHub 上發布。

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.

展望未來，Chain Signatures 的開發路線圖包括在年底前增加對 EDDSA 橢圓曲線的支持，這將擴大對 Solana 和 TON 等鏈的兼容性。此外，該團隊的目標是提高吞吐量以匹配 NEAR 的分片容量，目標是每秒處理高達 300 筆交易。隨著時間的推移，網路上驗證器的數量預計會增長，目標是實現 40 多個高度獨立的節點，單一簽章需要 27 個節點。
