Design with custodial script

The idea is that participants submit action UTXOs and then single "batcher" (as referred in some DEXes) runs those "actions" by submitting transactions that can spend state UTXO. The difference form existing batchers is that batcher - is leader picked among participants in trustless manner.

Step 1

Each participant builds and submits "action" transaction that creates UTXO at custodial script address.
