While it does not itself execute or broadcast the transaction, it is a direct precursor to a financial/transfer operation. The preparation itself creates structured data that, if signed and broadcast, transfers assets.

{
"version": "1",
"default": "deny",
"tools": {
"prepareERC1155Transfer": {
"limits": [
{
"counter": "prepareerc1155transfer_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
