Chain Signatures Mainnet Release: A Pioneering Chain Abstraction Solution for the NEAR Platform

Today marks a significant milestone with the official Mainnet release of Chain Signatures, a pioneering Chain Abstraction solution developed on the NEAR platform.

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.

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.

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.

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.

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.

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.

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.

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.

The Chain Signatures Mainnet dijamin oleh lapan pengesah yang bereputasi, termasuk Pagoda, Luganodes, The Lifted Initiative, InfStones, Staking4All, Node.Monster, Black Sand Technologies dan Aurora. Audit awal protokol Chain Signatures telah dijalankan oleh Kudelski, dengan laporan akhir ditetapkan untuk diterbitkan tidak lama lagi di Chain Signatures GitHub.

Melihat ke hadapan, pelan hala tuju pembangunan untuk Tandatangan Rantaian termasuk menambah sokongan untuk lengkung elips EDDSA sebelum akhir tahun, yang akan mengembangkan keserasian kepada rantai seperti Solana dan TON. Selain itu, pasukan itu menyasarkan untuk meningkatkan daya pengeluaran agar sepadan dengan kapasiti pecahan NEAR, menyasarkan sehingga 300 transaksi sesaat. Dari masa ke masa, bilangan pengesah pada rangkaian dijangka berkembang, dengan matlamat untuk mencapai 40+ nod yang sangat bebas, memerlukan 27 untuk satu tandatangan.
