func (*Wallet) GetMintQuotes 

func (w *Wallet) GetMintQuotes() []storage.MintQuote

func (*Wallet) GetPendingMeltQuotes 

func (w *Wallet) GetPendingMeltQuotes() []string

GetPendingMeltQuotes return a list of pending quote ids

func (*Wallet) GetReceivePubkey 

func (w *Wallet) GetReceivePubkey() *btcec.PublicKey

GetReceivePubkey retrieves public key to which the wallet can receive locked ecash

func (w *Wallet) HTLCLockedProofs(
	amount uint64,
	mintURL string,
	preimage string,
	tags *nut11.P2PKTags,
	includeFees bool,
) (cashu.Proofs, error)

HTLCLockedProofs returns proofs that are locked to the hash of the preimage

func (*Wallet) Melt 

func (w *Wallet) Melt(quoteId string) (*nut05.PostMeltQuoteBolt11Response, error)

Melt will melt proofs by requesting the mint to pay the payment request from the melt quote passed
