rebalanceExpiryCash function

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

Move cash between pool idle liquidity and one expiry market.

Permissionless and standalone: anyone may call it at any cadence. Handles all three per-market cases — initial funding of a freshly registered (unfunded) market, ongoing live rebalance/surplus-sweep toward target, and the settled-market sweep (deactivate, return all free cash, materialize profit). Call expiry_market::try_settle first in the same PTB when settlement may be due. An expired unsettled market is a no-op until that transition succeeds. Mint asserts backing but never pulls pool cash, so this is what makes a market mintable. The market must already be registered to this vault (registry::create_and_share_expiry_market). Runs at any time, including while a flush is in flight — every figure the mark reads was frozen at the snapshot instant, so no move here can reach it. The one refusal is the still-open snapshot stage (start → seal, a single transaction): a cross-move landing between a market's stamp and the seal's vault capture would skew the frozen figures, so it is structurally rejected rather than corrected for.

Implementation

MoveCallBuilder rebalanceExpiryCash(
    {dynamic arguments, String? package, Map<String, dynamic>? config}) {
  final packageAddress = package ??
      (config?['predictPackageId'] as String?) ??
      '@local-pkg/deepbook_predict';
  return (tx) => tx.moveCall(
        '$packageAddress::plp::rebalance_expiry_cash',
        arguments: normalizeMoveArguments(
            tx,
            withConfigDefaults(arguments, config,
                const {'vault': 'poolVault', 'config': 'protocolConfig'}),
            [null, null, null, '0x2::clock::Clock'],
            ['vault', 'market', 'config']),
      );
}
