All trading actions are batched via Controller.execute. For each item in actionList you provide an ABI‑encoded params struct in paramsDataList.

​
MAKE (post a limit)

The MAKE action allows you to post a limit order on the book at a specific tick (price level).

​
MakeOrderParams struct

MakeOrderParams(
  id: uint192,
  tick: int24,

  referrer: address

  { name: 'referrer', type: 'address' },
] as const;

const makeData = encodeAbiParameters(makeTypes, [
  bookId,

  quoteAmount,
  '0x0000000000000000000000000000000000000000', // referrer (use address(0) if none)
