Switch charges: Tokens robotically pay a charge upon switch, very similar to the royalties NFTs typically pay to their artists after they’re bought on the secondary market. However not like NFT royalties, which have suffered from varied marketplaces refusing to implement them, charges applied by way of token extensions cannot be bypassed.
Confidential transfers: Tokens will use zero-knowledge proofs to cover confidential data like fee quantity throughout transfers. Chain sleuths will have the ability to see that x deal with despatched tokens to y deal with, however not how a lot they despatched.
Everlasting delegate authority: Token issuers can retain management over their tokens, notably the flexibility to switch and even destroy them irrespective of who their holder is. The briefing supplies envision this being helpful for stablecoins, securities tokens and credentials.
