About MetaMask
We’re building for a future where the internet and world economy empowers people through interactions based on consent, privacy, and free association, where both communities and individuals flourish. To accomplish that, we’re working hard to make web3 accessible for everyone.
MetaMask is both a crypto wallet and a gateway to the decentralized web. Our tools help people create communities, play video games, access financial services, make payments, invest in assets, protect against economic turmoil, and more. Our browser extension and mobile platforms meet the needs of millions of users and developers across the world.
The MetaMask Wallet API Platform Team
Empowering developers to deliver great decentralized user experiences is at the heart of MetaMask’s purpose. From the beginning, we have done so by providing the web with an API that allows any developer to turn their site or web-app into a decentralized app connected to the blockchain.
Currently the MetaMask Wallet API allows dApps to do things like: propose transactions to users, access the address of the users current account, use keys in MetaMask to help users encrypt and decrypt messages, propose to users that they sign specific messages, access the connected node/provider and call all methods on the Ethereum RPC API, and to propose that users add and switch to a specific network. We enhance and expand this list of capabilities and build tools to help other teams build new capabilities themselves.
To get a fuller picture of the current API, you can check out our documentationhttps://docs.metamask.io/wallet/concepts/wallet-api/
By improving and expanding this API, we can make entirely new types of decentralized user experiences possible. There is also much work to do to make this API accessible for the many new developers joining our space.
We are hiring engineers to join our Wallet API Platform team and help us build the platform on which the world’s most exciting dapps will be built.
What you’ll do
- Build and maintain Wallet API infrastructure and tooling.
- Help to manage and govern a pipeline of proposed new APIs.
- Work with partners and standards bodies across the Web3 ecosystem to shape wallet API standards.
