ContractBuilder

class ContractBuilder

DSL builder for creating a MidnightContract.

Properties

address

var address: String?

Deployed contract address (64 hex chars).

circuitVerifierKeys

var circuitVerifierKeys: Map<String, ByteArray>

Circuit verifier keys for deploy — map of circuit name to raw verifier key bytes. Load from the compiled contract's keys/{circuit}.verifier files. Required for deploy, not needed for call.

coinPublicKey

var coinPublicKey: ByteArray?

Coin public key (32 bytes). Required.

constructorArgs

var constructorArgs: List<Any?>

Arguments for the contract constructor, in declaration order, as Kotlin values (auto-marshaled to JS like circuit call args). Empty for a no-arg constructor (the counter/bboard case). A configurable contract — e.g. a multisig taking its signer set + threshold — passes them here.

contractJs

var contractJs: InputStream?

Contract JavaScript as an InputStream. Accepts either:

initialPrivateState

var initialPrivateState: Map<String, Any?>

Initial private state as a Kotlin map (auto-converted to JS).

name

var name: String?

Contract name (used for proving key management).

Functions

witness

fun witness(name: String, provider: WitnessProvider)
