type Spender

type Spender interface {
	// Spend the provided amount while deducting the provided fee.
	// Arguments:
	// - [keys] are the owners of the funds
	// - [amount] is the amount of funds that are trying to be staked
	// - [fee] is the amount of AVAX that should be burned
	// - [changeAddr] is the address that change, if there is any, is sent to
	// Returns:
	// - [inputs] the inputs that should be consumed to fund the outputs
	// - [returnedOutputs] the outputs that should be immediately returned to
	//                     the UTXO set
	// - [stakedOutputs] the outputs that should be locked for the duration of
	//                   the staking period
	// - [signers] the proof of ownership of the funds being moved
	Spend(

		subnetID ids.ID,
		keys []*secp256k1.PrivateKey,
	) (
		verify.Verifiable,
		[]*secp256k1.PrivateKey,
		error,
	)
}

TODO: Stake and Authorize should be replaced by similar methods in the P-chain wallet

type Verifier
