Returns the wallet's public key encoded as Base58.

Parameters

An object containing:

• derivationPath - Derivation paths segments that will be appended to m/44'/501'
• confirm - Whether to show a confirm dialog.

Returns

Base58 encoded public key.

Example:

ethereum.request({
  method: 'wallet_invokeSnap',
  params: {
    snapId: 'npm:@solflare-wallet/solana-snap',
    request: {
      method: 'getPublicKey',
      params: {
        derivationPath: [`0'`, `0'`],
        confirm: true
      }
   }
  }
});

signTransaction

Sign a transaction and return the signature encoded as Base58.

Parameters

An object containing:

• derivationPath - Derivation paths segments that will be appended to m/44'/501'
• message - Transaction message encoded as Base58

Returns

An object containing:

• publicKey - Base58 encoded public key
• signature - Transaction signature encoded as Base58

Example:

ethereum.request({
  method: 'wallet_invokeSnap',
  params: {
    snapId: 'npm:@solflare-wallet/solana-snap',
    request: {
      method: 'signTransaction',
      params: {
        derivationPath: [`0'`, `0'`],
        message: '...'
      }
   }
  }
});

signAllTransactions

Sign multiple transactions and return the signatures encoded as Base58.

Parameters

An object containing:

• derivationPath - Derivation paths segments that will be appended to m/44'/501'
• messages - An array of transaction messages encoded as Base58

Returns

An object containing:

• publicKey - Base58 encoded public key
• signatures - An array of transaction signatures encoded as Base58

Example:

ethereum.request({
  method: 'wallet_invokeSnap',
  params: {
    snapId: 'npm:@solflare-wallet/solana-snap',
    request: {
      method: 'signAllTransactions',
      params: {
        derivationPath: [`0'`, `0'`],
        messages: ['...', '...']
      }
   }
  }
});

signMessage

Sign a message (can be either arbitrary bytes or a UTF-8 string) and return the signature encoded as Base58.

Parameters

An object containing:

• derivationPath - Derivation paths segments that will be appended to m/44'/501'
• message - Message encoded as Base58
• display - How to decode and display the message, utf8 or hex

Returns

An object containing:

• publicKey - Base58 encoded public key
• signature - Message signature encoded as Base58

Example:

const bytes = new TextEncoder().encode('Lorem ipsum');
const base58Message = base58.encode(bytes);

ethereum.request({
  method: 'wallet_invokeSnap',
  params: {
    snapId: 'npm:@solflare-wallet/solana-snap',
    request: {
      method: 'signMessage',
      params: {
        derivationPath: [`0'`, `0'`],
        message: base58Message,
        display: 'utf8'
      }
   }
  }
});
