Legal stuff:
Base provides neutral protocol infrastructure only and does not control the persons, applications, or assets that use it. B20 tokens are deployed, configured, and administered solely by their respective issuers; issuer-controlled features such as minting, burning, freezing, and seizure are exercised at the issuer's sole discretion.
seizeWithMemo lets authorized admins reassign a holder’s balance as a transfer
The onchain record shows who it moved from, where it went, how much, and the memo
Schedule Multiplier Updates allows issuers to schedule their corporate actions, such as a stock split, in advance
Multiplier changes are displayed at the user interface, such as a wallet balance. Raw balances and transfer behavior are unchanged
Composite Policies allow token issuers to combine allowlists and blocklists with OR or AND logic
This means live policies, like KYC allowlists and sanctions blocklists, can be reused without duplicating them
There are three B20 enhancements in Cobalt:
- Composite Policies
- Schedule Multiplier Updates
- seizeWithMemo
Here’s how they simplify and improve B20 ↓
Validity Transactions give advanced traders more control over the conditions and timing for eligible transaction inclusion on Base
Users submit a transaction with a set of validity criteria. It remains private until the criteria are met, then executes
