solana_signTransaction

This method returns a signature over the provided instructions by the targeted public key.

  • Object - instruction
    
  • programId : String - public key of the on chain program
    
  • data : String | undefined - encoded calldata for instruction
    
  • keys : Array of Object - account metadata used to define instructions
    
  • Object - key
    
  • isSigner : Boolean - true if an instruction requires a transaction signature matching pubkey
    
  • isWritable : Boolean - true if the pubkey can be loaded as a read-write account
    
  • pubkey : String - public key of authorized program
    
• [deprecated] recentBlockhash : String | undefined - a recent blockhash
  
• [deprecated] signatures : Array of Object or undefined - (optional) previous partial signatures for this instruction set
  
  • Object - partial signature
    
  • pubkey : String - pubkey of the signer
    
  • signature : String - signature matching pubkey
    

​

Returns

Object:

• signature: String - corresponding signature for signed instructions
• transaction?: String | undefined - optional: base64-encoded serialized transaction

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

Object - Signing parameters:

• transactions : String[] - base64-encoded serialized list of transactions
  

​

Returns

Object:

• transactions : String[] - base64-encoded serialized list of signed transactions in the same order as received

Example

// Request
{
	"id": 1,
	"jsonrpc": "2.0",
	"method": "solana_signAllTransactions",
	"params": {
    "transactions": string[]
	}
}

// Response
{
	"id": 1,
	"jsonrpc": "2.0",
	"result":  {
	  "transactions": string[]
	}
}

​

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:

• transaction : String - the whole transaction serialized and encoded with base64
  
• sendOptions : Object - options for sending the transaction
  
  • skipPreflight : Boolean - skip preflight checks
    
  • preflightCommitment : 'processed' | 'confirmed' | 'finalized' | 'recent' | 'single' | 'singleGossip' | 'root' | 'max' - preflight commitment level
    
  • maxRetries : Number - maximum number of retries
    
  • minContextSlot : Number - minimum context slot
    

​

Returns

Object:

• signature : String, - the signature of the transaction encoded with base58 used as transaction id
  

​

{
	"id": 1,
	"jsonrpc": "2.0",
	"method": "solana_signAndSendTransaction",
	"params": {
