USD Coin (USDC<\/a>) issuer Circle has released a beta version of a multiparty computation (MPC) wallet service, according to an Aug. 8 announcement. The new service will allow developers of decentralized finance (DeFi) apps, Web3 video games, e-commerce services and other blockchain applications to create customized wallets specifically for their users. It will be available initially on Ethereum, Avalanche and Polygon.<\/p>\n Building crypto apps is still too hard. Plus, less than 0.5% of the 100 million developers worldwide are actively building crypto apps today.<\/p>\n This needs to change. Our new wallet-as-a-service developer platform is a huge step in that regard. Check it out https:\/\/t.co\/ku9LTz8Z97<\/a><\/p>\n \u2014 Patrick Hansen (@paddi_hansen) August 8, 2023<\/a><\/p><\/blockquote>\n MPC wallets are secured by splitting a user\u2019s private key<\/a> into multiple shards and distributing them through a decentralized network. It\u2019s a\u00a0new wallet technology<\/a>\u00a0many Web3 developers have been using. MPC wallets can be accessed via an application programming interface, giving them a \u201cWeb2 feel\u201d that some developers and users prefer.<\/p>\n According to an explanatory blog post from Circle, the new service will allow<\/a> developers to \u201cchoose the best wallet security and control configurations.\u201d For example, some developers may want to host their own MPC nodes to ensure they are not completely reliant on Circle, while others may want to choose the simpler method of connecting to Circle\u2019s nodes. Developers can also choose to \u201cshare transaction signing responsibilities with the users,\u201d allowing them to recover keys if users lose them, or they can make the product noncustodial by requiring users to sign every transaction.<\/p>\n According to Circle co-founder and CEO Jeremy Allaire, the new service is essential in promoting the use of USDC:<\/p>\n \u201cCircle\u2019s Programmable Wallets is part of a new, core pillar of our strategy to advance\u00a0global, mainstream utility and adoption of digital assets like USDC and public\u00a0blockchain-based payments. This new platform marks the first step for Circle\u2019s Web3 services as we work to ease common pain points for developers.\u201d<\/p><\/blockquote>\n MPC wallets have faced controversy, with the widely used Multichain MPC bridge hacked on July 7<\/a>, causing investors to lose over $100 million. The Multichain team later admitted that all MPC shards had been stored on a cloud server<\/a> under the control of the CEO.<\/p>\n In an emailed statement to Cointelegraph, Circle\u2019s senior director of product management, Gagan Mac, claimed that the new service \u201cis built and maintained in-house and doesn\u2019t leverage external vendors,\u201d implying that third-party cloud storage systems will not be used. In addition, Gagan stated that \u201csome developers and enterprises may prefer to host an MPC node,\u201d which they will be allowed to do if they wish. Multichain did not allow partners to host their own nodes.<\/p>\n Circle recently stated that the demand for euro-based stablecoins is heating up<\/a> and also argued that a yuan stablecoin would be better than a Chinese central bank digital currency<\/a>.<\/p>\n<\/div>\n\n
