Provider API

Use the provider for your target chain to request accounts, signatures, and transactions. Each chain has its own methods, encodings, and events; an Ethereum request example is not interchangeable with a Bitcoin or Solana example.

What this gives you

• Chain-specific references: Find connection, signing, transaction, and event documentation for each provider.
• Connection options: Use a wallet UI library for a chooser, or access the injected provider directly.
• Implementation guidance: Check network and account state, handle rejected requests, and clean up event listeners.

Supported Chains

• EVM: Ethereum, Polygon, BSC, Arbitrum, Optimism, Base, etc.
• Bitcoin: BTC, Lightning Network (WebLN)
• Solana: SOL
• Cosmos: ATOM and Cosmos SDK chains
• Move: Aptos, Sui
• Others: Stellar, TON, TRON, Polkadot, Cardano, Algorand, Conflux, NEAR, Nostr
