A keyset is a set of public keys, each associated with a token value. The mint uses the key appropriate to the amount to perform the signature on the corresponding blinded message.

KeysetId

@JvmInline

value class KeysetId(val value: String)

A KeysetId is a unique identifier for a Keyset.

KeysetJson

@Serializable

data class KeysetJson(val id: String, val unit: String = "sat", val keys: Map<ULong, String>)

PaymentMethod

enum PaymentMethod : Enum<PaymentMethod>

PaymentRequestSerializer

object PaymentRequestSerializer : KSerializer<PaymentRequest>

PreRequestBundle

interface PreRequestBundle

Proof

@Serializable

data class Proof(val amount: ULong, val id: String, val secret: String, val C: String, val script: String? = null)

Cashu token.

Secret

class Secret

Secret used to generate a token. This is the x in NUT-00, the bytes we'll use in the hashToCurve function to generate key Y.

SpecificKeysetResponse

typealias SpecificKeysetResponse = ActiveKeysetsResponse

The data structure the mint returns when we ask for a specific keyset.

SwapRequired

sealed class SwapRequired

TokenEntry

@Serializable

data class TokenEntry(val mint: String? = null, val proofs: List<Proof>)

TokenV3

@Serializable

data class TokenV3(val tokenEntries: List<TokenEntry> = listOf(), val unit: String? = null, val memo: String? = null)

A Cashu token that includes proofs and their respective mints. Can include proofs from multiple different mints and keysets.
