Base Completed the third mainnet upgrade, adding Validity Transactions and expanding B20 asset functionality
BlockBeats reported that October 1，Base completed the third mainnet upgrade, Cobalt. The core of this upgrade is Validity Transactions Validity Transactions, which allow users to submit transactions with attached validity conditions. They are packaged on-chain only when the conditions are met; if the conditions are not met, the transactions will never be included.Base stated that API is neutral infrastructure, allowing submissions from advanced traders to remain private before execution.
Cobalt also enhanced the June Beryl upgrade's B20 token standard by adding three features.Composite Policies allows asset issuers to combine existing allowlists and denylists using "OR" and "AND" logic, without duplicating lists or maintaining off-chain synchronization.Schedule Multiplier upgrade aligns with the ERC-8056 standard and supports changes to the way asset balances are displayed as preset by issuers, which can be used in scenarios such as stock splits.seizeWithMemo The seizeWithMemo feature allows authorized administrators to reallocate holder balances for assets with freezing enabled, while recording the source, destination, amount, and memo on-chain.Base also disclosed plans to shorten the block time from 2 seconds to 200 milliseconds over the coming months, implement native smart accounts at the protocol layer, support gas sponsorship and transaction batching, and introduce some of the EVM improvements from Ethereum's Glamsterdam upgrade.

04
Cobalt added B20 to the token standard Composite Policies、Schedule Multiplier upgrade and seizeWithMemo three features.
05
Composite Policies Allows asset issuers to combine existing allowlists and denylists using "OR" and "AND" logic.
06
Schedule Multiplier The upgrade aligns with the ERC-8056 standard and supports changes to the preset way asset balances are displayed.
07
seizeWithMemo Allows authorized administrators to reallocate holder balances for assets with freezing enabled, while recording the source, destination, amount, and memo on-chain.
08
Base disclosed plans over the coming months to shorten block times, implement native smart accounts, support gas sponsorship and transaction batching, and introduce some EVM improvements.
AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
This upgrade allows transactions to carry conditions in advance and be put on-chain only when those conditions are met; at the same time,B20 asset issuers gained the ability to combine list rules, adjust balance display methods, and reallocate balances for assets with freezing enabled, with a memo.
Why it matters to readers
The upgrade expanded infrastructure support for Base Validity Transactions and B20 asset management; the ability for administrators to reallocate balances also means that attention should be paid to how permissions are constrained.
Beginners can understand Validity Transactions as transactions that "execute only when preset conditions are met." When using B20 assets, they should also note whether issuers or authorized administrators have permission to freeze assets and reallocate balances.
Risks and unknowns
The evidence provides only a BlockBeats report and the original link; it does not provide a Base official announcement link.
Plans for faster block times, native smart accounts, gas sponsorship, batching, and EVM improvements over the coming months remain unconfirmed, and it cannot be confirmed whether they will be implemented as planned.
The evidence does not state the Validity Transactions actual usage, compatibility, or operational performance of the B20 new features.
The evidence does not state the specific governance, audit, or constraint mechanisms for seizeWithMemo authorized administrator permissions.
