transfer static method

TransactionInstruction transfer({ required Pubkey source, required Pubkey destination, required Pubkey owner, List<Pubkey> signers = const [], required bu64 amount, })

Transfers tokens from one account to another either directly or via a delegate. If this account is associated with the native mint then equal amounts of SOL and Tokens will be transferred to the destination account.

Keys:

Single owner/delegate

• [w] source - The source account.
• [w] destination - The destination account.
• [s] owner - The source account's owner/delegate.

Multisignature owner/delegate

• [w] source - The source account.
• [w] destination - The destination account.
• [] owner - The source account's multisignature owner/delegate.
• [s] signers - The signer accounts.

Data:

• amount - The amount of tokens to transfer.
