Thugbirdz is going through a process called entanglement. This means that the metadata for the entire collection are updated without changing the art and attributes of the NFT's.
1) Because we are one of the earliest collections on solana.
The collection was launched in the pre candy machine era, using multiple different wallets and spread out over multiple days.
As a result the collection has NFTs with different mutability status and update authorities.
This creates all sorts of problems with listing on multiple marketplaces (f.e. opensea) and collection-specific blockchain applications that we want to develop.
We basically need to make all NFT's mutable with the same update authority.
2) Because thugDAO is getting a larger part of the royalties on secondary sales (it was 0% and is going to be 45%). This will grow the DAO treasury and enable us to build more cool stuff.
Solana Sanctuary (spun out of exiled apes) has built an entangler (the Merkle Reloader) for us. You can reload/swap your old NFT for a fresh one at: https://swap.thugbirdz.com. Check out the screenshots below for a walkthrough of the process.
