Event v101 → v148, v149 → current #3

Emitted when an account's balance is set by root.

From Chain Metadata

A balance was set by root.

Migration Notes

v148 v149 Breaking

removed field reserved (was u64)

Update decoders: SCALE encoding is positional, so any signature change (added, removed, or type-changed fields, or storage shape changes) shifts byte offsets and existing decoders will misparse this item. Re-derive types from the new metadata.
