MidnightSdk

class MidnightSdk

Top-level entry point for the Midnight Android SDK.

Provides a fully standalone environment for dApps: contract execution, local proving, embedded wallet (dust fee payment), and node submission. No external wallet process (mn serve) required.

val sdk = MidnightSdk.Builder(context)
    .network(MidnightNetwork.PREPROD)
    .seed(mnemonicSeed)
    .build()

val contract = MidnightContract.create(sdk.config) {
    contractJs = assets.open("runtime/my-contract-iife.js")
    address = contractAddress
    coinPublicKey = sdk.coinPublicKey
    // ... witnesses, private state
}

val receipt = contract.call("myCircuit", arg1) // Fully standalone
sdk.close()
