Required methods

fn send_and_confirm_message<T: Signers>(
    &self,
    keypairs: &T,
    message: Message
) -> Result<Signature>

Create a transaction from the given message, and send it to the server, retrying as-needed.

fn send_and_confirm_instruction(
    &self,
    keypair: &Keypair,
    instruction: Instruction
) -> Result<Signature>

Create a transaction from a single instruction that only requires a single signer. Then send it to the server, retrying as-needed.

fn transfer_and_confirm(
    &self,
    lamports: u64,
    keypair: &Keypair,
    pubkey: &Pubkey
) -> Result<Signature>

Transfer lamports from keypair to pubkey, retrying until the transfer completes or produces and error.

fn get_account_data(&self, pubkey: &Pubkey) -> Result<Option<Vec<u8>>>

Get an account or None if not found.

fn get_account(&self, pubkey: &Pubkey) -> Result<Option<Account>>

Get an account or None if not found.

fn get_account_with_commitment(
    &self,
    pubkey: &Pubkey,
    commitment_config: CommitmentConfig
) -> Result<Option<Account>>

Get an account or None if not found. Uses explicit commitment configuration.

fn get_balance(&self, pubkey: &Pubkey) -> Result<u64>

Get account balance or 0 if not found.

fn get_balance_with_commitment(
    &self,
    pubkey: &Pubkey,
    commitment_config: CommitmentConfig
