Approve Max Builder Fee

Function:

{package}::dex_accounts_entry::approve_max_builder_fee_for_subaccount

ABI Object:

const functionAbi: MoveFunction = {
  name: "approve_max_builder_fee_for_subaccount",
  visibility: "private",
  is_entry: true,
  is_view: false,
  generic_type_params: [],
  params: [
    "&signer",
    "0x1::object::Object<{package}::dex_accounts::Subaccount>",
    "address",
    "u64",
  ],
  return: [],
};

Parameters:

signer - The account signer
subaccount - The Trading Account object
builder_addr - The builder address
max_fee - Maximum fee (u64) in units of 0.0001% (basis points × 100; e.g. 1000 = 10 bps = 0.1%, the protocol maximum). The TypeScript SDK takes basis points and does this conversion for you. Approvals above the protocol-wide cap of 1000 abort with EINVALID_MAX_FEE

Example:

const transaction = await aptos.transaction.build.simple({
  sender: account.accountAddress,
  data: {
    function: `${PACKAGE}::dex_accounts_entry::approve_max_builder_fee_for_subaccount`,
    typeArguments: [],
    functionArguments: [
      "0x123...abc", // subaccountAddr
      "0xabc...123", // builderAddr (builder/referrer address)
      1000, // maxFee (0.0001% units: 1000 = 10 bps = 0.1%, the protocol maximum)
    ],
  },
});

transaction = rest_client.build_transaction(
    sender=account.address(),
    payload={
        "function": f"{PACKAGE}::dex_accounts_entry::approve_max_builder_fee_for_subaccount",
        "type_arguments": [],
        "function_arguments": [
            "0x123...abc",  # subaccountAddr
            "0xabc...123",  # builderAddr (builder/referrer address)
            1000,  # maxFee (0.0001% units: 1000 = 10 bps = 0.1%, the protocol maximum)
        ],
    },
)
