Binance, the world's largest cryptocurrency exchange, has announced the launch of a new Web3 self-custody wallet designed to simplify the user experience when interacting with decentralized applications (dApps) while strengthening fund security. The wallet's key innovation is the use of multi-party computation (MPC) technology, which allows users to manage their wallet without memorizing or handling complex seed phrases.
Lowering the Barrier for Web3 Adoption
Changpeng “CZ” Zhao, founder and CEO of Binance, stated in a press release: “To help drive Web3 adoption, we have to identify and plug the gaps between centralized and decentralized systems. Binance's Web3 Wallet lowers the barriers of entry for users to achieve full self-custody of their assets and it is an important, convenient bridge towards DeFi empowerment.” CZ has previously warned about the risks of self-custody wallets, but he now believes the new technology can solve key user pain points.
Richard Teng, Binance's Head of Regional Markets, added that besides user experience, security was a major focus during the wallet's development. He emphasized that users can “be assured that they are interacting with Web3 within a secure and protected ecosystem” and that the common stress of worrying about losing one's seed phrase is removed, encouraging more users to explore decentralized applications.
MPC Technology: Self-Custody but Not Fully Non-Custodial
Notably, Binance describes the wallet as “self-custodial,” but this differs from the traditional crypto understanding of non-custodial wallets, where the user has complete control over the entire private key. The Binance wallet employs key sharding: the key is split into three shards stored in different locations, with two shards controlled by the user and one held by Binance or a third party. This design reduces the risk of the private key being fully compromised while also meaning Binance retains some involvement in key management. The press release explains: “Having the key-shares split across three different locations mitigates the risk of the keys being compromised and reduces the vulnerability of the system. Two out of the three key-shares are controlled by users.”
Powered by Trust Wallet's Wallet-as-a-Service
Binance revealed that the new wallet is an implementation of Trust Wallet's Wallet-as-a-Service (WaaS) suite. This white-label toolkit allows third parties to quickly offer Web3-based services to their customers without building an in-house wallet. Trust Wallet claims that using its WaaS solution reduces development time “from years to months,” enabling companies to focus on their core businesses rather than wallet infrastructure.
Trust Wallet, founded in 2017 and acquired by Binance in 2018, was originally described by Binance as adding “an on-chain mobile wallet to the list of Binance services,” hinting at future integrations. The new Web3 wallet is the latest result of that integration.
Overall, Binance's Web3 wallet strikes a balance between simplified user experience and security, though its definition of “self-custody” differs from the pure decentralized ideal. With its launch, more users can now access the decentralized finance world with a lower learning curve.
