mintExactAmount function

MoveCallBuilder mintExactAmount({ dynamic arguments, String? package, Map<String, dynamic>? config, })

Mint a conservatively sized lot-rounded position whose premium does not exceed max_premium. The result may be one lot below the largest fitting quantity and must meet min_quantity.

Fees, builder fees, and EWMA congestion penalties are charged on top of max_premium, so max_cost — not max_premium — bounds the all-in USDC withdrawal (premium + trader-paid fee + builder_fee + EWMA penalty). max_cost is required: unlike mint_exact_quantity's guards there is no value that disables it, because the budget shape exists to bound spend. The sizing budget is first capped to the account's available USDC after settlement; fees still require additional available USDC at payment time. Any unspent premium dust remains in the account because order quantity must be an integer number of position_lot_size lots.

Implementation

MoveCallBuilder mintExactAmount(
    {dynamic arguments, String? package, Map<String, dynamic>? config}) {
  final packageAddress = package ??
      (config?['predictPackageId'] as String?) ??
      '@local-pkg/deepbook_predict';
  return (tx) => tx.moveCall(
        '$packageAddress::expiry_market::mint_exact_amount',
        arguments: normalizeMoveArguments(
            tx,
            withConfigDefaults(
                arguments, config, const {'config': 'protocolConfig'}),
