This is a temporary workaround to allow a Filecoin key transfer tx to be processed. This workaround allows validators to avoid having to sync an archival node for Filecoin to process this tx The tx receipt is hardcoded below and can be verified against your own archival node or the explorer https://filfox.info/en/tx/0x44ca58be45e862026202bc7a3c4dc897804264d29f087b9a1249f9f4bf1e31d7
