Every fix re-validated before finalization. What matters isn't one audit. It's three in sequence, each confirming the previous fixes held.

What's coming next is close. ## Publication Information - [Royco](https://blog.royco.org/): Publication homepage - [All Posts](https://blog.royco.org/): More posts from this publication - [RSS Feed](https://api.paragraph.com/blogs/rss/@royco): Subscribe to updates - [Twitter](https://twitter.com/roycoprotocol): Follow on Twitter
