-## solana_signMessage
 
-This method returns a signature for the provided message from the requested signer address.
+## solana_signAllTransactions
+
+This method is responsible for signing a list of transactions. The wallet must sign all transactions and return the signed transactions in the same order as received. Wallets must sign all transactions or return an error if it is not possible to sign any of them.
 
 ### Parameters

-    	1.1. `message` : `String` -  the message to be signed (base58 encoded)
-    	1.2. `pubkey` : `String` -  public key of the signer
+`Object` - Signing parameters:
+- `transactions` : `String[]` - base64-encoded serialized list of transactions<br />
 
 ### Returns
 
-    1. `Object`
-    	1.1. `signature` : `String` - corresponding signature for signed message

+
+## solana_signAndSendTransaction
+
+This method is responsible for signing and sending a transaction to the Solana network. The wallet must sent the transaction and return the signature that can be used as a transaction id.
+
+### Parameters
+
+`Object` - transaction and options:<br />
+- `transaction` : `String` - the whole transaction serialized and encoded with base64<br />
+- `sendOptions` : `Object` - options for sending the transaction<br />
+	- `skipPreflight` : `Boolean` - skip preflight checks<br />
+	- `preflightCommitment` : `'processed' | 'confirmed' | 'finalized' | 'recent' | 'single' | 'singleGossip' | 'root' | 'max'` - preflight commitment level<br />
+	- `maxRetries` : `Number` - maximum number of retries<br />
+	- `minContextSlot` : `Number` - minimum context slot<br />
+
+### Returns
+
+`Object`:
+- `signature` : `String`, - the signature of the transaction encoded with base58 used as transaction id<br />
+
+### Example
+
+```typescript
