ClientWithPayer

type ClientWithPayer = object;

Represents a client that provides a default transaction payer.

The payer is a TransactionSigner used to sign and pay for transactions. Clients implementing this interface can automatically fund transactions without requiring callers to specify a fee payer explicitly. Unlike ClientWithIdentity, which describes the signer whose assets the application is acting upon, the payer describes the signer responsible for paying transaction fees as well as storage costs — i.e. the minimum balance required to keep newly created accounts alive based on their size. In many apps the payer and identity refer to the same signer, but they can differ — for example, when a service pays fees on behalf of a user.

Example

function createTransfer(client: ClientWithPayer, recipient: Address, amount: Lamports) {
    const feePayer = client.payer;
    // Use feePayer.address as the transaction fee payer
}
