There’s no easy way to get the constraints of circuits at this time so the constraints of the circuits listed below have been omitted.

Circuits
isKeyOrAddressZero(
keyOrAddress: Either<ZswapCoinPublicKey, ContractAddress>
) → Boolean
circuit
#Returns whether keyOrAddress
is the zero address.
Midnight's burn address is represented as left<ZswapCoinPublicKey, ContractAddress>(default<ZswapCoinPublicKey>)
in Compact,
so we've chosen to represent the zero address as this structure as well.
isKeyZero(key: ZswapCoinPublicKey) → Boolean
circuit
#Returns whether key
is the zero address.
isKeyOrAddressEqual(
keyOrAddress: Either<ZswapCoinPublicKey, ContractAddress>,
other: Either<ZswapCoinPublicKey, ContractAddress>
) → Boolean
circuit
#Returns whether keyOrAddress
is equal to other
.
Assumes that a ZswapCoinPublicKey
and a ContractAddress
can never be equal.
isContractAddress(
keyOrAddress: Either<ZswapCoinPublicKey, ContractAddress>
) → Boolean
circuit
#Returns whether keyOrAddress
is a ContractAddress
type.
emptyString() → Opaque<"string">
circuit
#A helper function that returns the empty string: ""
.
