IMetaV1
Events
MetaV1
An onchain wrapper to carry arbitrary Rain metadata. Assigns the sender to the metadata so that tooling can easily drop/ignore data from unknown sources. As metadata is about something, the subject MUST be provided.
event MetaV1(address sender, uint256 subject, bytes meta);
Parameters

---|---|---|
sender | address | The msg.sender. |
subject | uint256 | The entity that the metadata is about. MAY be the address of the emitting contract (as uint256 ) OR anything else. The interpretation of the subject is context specific, so will often be a hash of some data/thing that this metadata is about. |
