MidnightConfig

Configuration for Midnight contract operations.

Created once per app, shared across all MidnightContract instances. Manages indexer connectivity, transaction balancing, and proving.

Two modes:

Remote wallet: provide walletUrl to delegate balancing to mn serve via WebSocket
Embedded wallet: provide a TransactionBalancer directly (e.g., MidnightWallet)

val previewConfig = NetworkConfig.forNetwork(MidnightNetwork.PREVIEW)

// Remote wallet (existing pattern)
val config = MidnightConfig.Builder(context)
    .indexerUrl(previewConfig.indexerBaseUrl)
    .walletUrl("ws://10.0.2.2:9932")
    .networkId(MidnightNetwork.PREVIEW.rustNetworkId)
    .build()

// Embedded wallet (new pattern)
val config = MidnightConfig.Builder(context)
    .indexerUrl(previewConfig.indexerBaseUrl)
    .transactionBalancer(myWallet)
    .networkId(MidnightNetwork.PREVIEW.rustNetworkId)
    .build()
