Provider API

Provider API is the browser-side entrance for DApp to interact with UKey Wallet. It organizes account connection, message signature, transaction sending and event monitoring into familiar calling methods for each chain, making it convenient for you to access multiple chains in the same set of products.

what you can get​

  • Multi-chain connection portal: Covers common ecosystems such as EVM, Bitcoin, Solana, Move, and Cosmos.
  • Easier access to UI: Can be used with components such as RainbowKit, Web3Modal, Wallet Adapter, etc. to complete the connection process.
  • Reset entry event model: Changes in account, network, and connection status will be notified to the application through events to facilitate synchronization of interface status.
  • Closer to production integration: Common methods, error codes and signature processes are divided into instructions by chain, reducing the guesswork cost during access.
