Version 1.0.0 Migration guide

⚠️ Upgrading to version 1.0.0 will come with breaking changes! Please follow the migration guide for a smooth transition to the new version.

Context

In Version 1.0.0 the api version of mints has been upgraded to v1. Please read the v1 v1 cleanup PR to understand more about how the API has changed.

Breaking changes

⚠️ Important! When upgrading to this version, the hash2curve function and the default secret format have changed. This means deterministic secret derivation will produce NOT THE SAME SECRETS as before. When upgrading to this version, wallets that have been using deterministic secrets (seed phrase) must reset counters and then self spend/refresh all proofs, so that the backups continue working.

Decoding LN invoices

Removed LN invoice decode: Decoding LN invoices is no longer used inside the lib.

How to fix: If you need to decode LN invoices, you can use

npm i @gandlaf21/bolt11-decode

CashuWallet interface changes

receive() no longer supports multi-token tokens

To reduce complexity, simplify error handling and to prepare for token V4, this feature has been removed. only the first token inside a token will be processed

optional function AND constructor parameters are now in an onpional options? Object

Utility functions now have an options object for optional parameters, instead of passing them directly

requestMint(amount: number) --> createMintQuote(amount: number) Now returns the following:

type MintQuoteResponse = {
	request: string;
	quote: string;
	paid: boolean;
	expiry: number;
	state: MintQuoteState;
};

where request is the invoice to be paid, and quote is the identifier used to pass to mintTokens().

requestTokens() --> mintTokens()

createMeltQuote(invoice: string) is now used to get fee estimation and conversion quotes instead of getFee() and returns:

type MeltQuoteResponse = {
	quote: string;
	amount: number;
	fee_reserve: number;
	paid: boolean;
	expiry: number;
	payment_preimage: string;
	state: MeltQuoteState;
	change?: Array<SerializedBlindedSignature>;
};

where quote is the identifier to pass to meltTokens()

receive() and receiveTokenEntry() now return Array<Proofs>

where Proofs are the newly created Proofs from the received token. Will now throw an error instead of returning proofsWithError

Model changes

MintKeys--> Keys: MintKeys now include the keys, id and unit

type MintKeys = {
	id: string;
	unit: string;
	keys: Keys;
};

type Keys = { [amount: number]: string };

MintKeyset: Used to be a string array, but now contains the additional fields active and unit

type MintKeyset = {
	id: string;
	unit: string;
	active: boolean;
};

BlindedMessages: now include the field id, corresponding with the mints keysetId

type BlindedMessage {
	amount: number;
	B_: ProjPointType<bigint>;
	id: string;
}

Pattern changes

removed newKeys from returns: Functions no longer return newKeys. Wallets now specify the keyset they use in the BlindedMessage via the id field.
