Does Zerion Wallet have an API?

Yes, Zerion Wallet does have an API that can be used to build feature-rich web3 apps, wallets, and protocols, providing access to wallets, assets, and chain data for web3 portfolios.  However, an alternative is to use Mesh, which has built integration with 300+ other digital assets, allowing developers to build products that access various cryptocurrencies from within their platform.

Headquartered in San Francisco, California, the company has a team of 11-50 employees and has raised over $22 million in funding. Zerion Wallet is non-custodial, meaning users maintain control of their funds, and it supports a wide range of opportunities across DeFi and NFTs, catering to both technical and non-technical users.
