The Ethereum L2 expands its B20 token standard and debuts price-conditional, private-until-inclusion transactions, sharpening its push into onchain finance.
Base released its Cobalt upgrade, adding issuer-grade compliance and trade controls aimed at tokenized finance on the Ethereum layer-2 network. The update is the network’s third major upgrade and extends the B20 token standard while introducing condition-based transaction handling, Base said.
What Cobalt changes in B20
Cobalt lets issuers apply multiple compliance checks to the same asset under B20 — for example, requiring recipients to pass identity verification, qualify as accredited investors and avoid sanctions lists, according to Base. Issuers can also schedule adjustments for corporate actions such as stock splits, changing the number of units displayed in wallets and apps without minting or burning tokens or altering the underlying balance.
Administrative controls are optional. Base said issuers can enable a feature that lets authorized administrators move tokens from a holder’s wallet without the holder’s approval and attach a public note to the transfer. Issuers decide who can use the feature. Base said it cannot initiate such transfers itself.

Validity Transactions
The upgrade introduces “Validity Transactions,” a mechanism for submitting transactions that only become eligible for inclusion when specific onchain conditions are met. Base said a trader could submit a swap that is valid only if an asset reaches a specified price before a set block deadline. The network would hold the transaction and evaluate the conditions as each block is built. Base added that transactions submitted through this system can remain private until they are included in a block, which can reduce information leakage before execution.
Strategy shift and recent steps
The move builds on Base’s tokenization push. On July 8, the network activated B20 as a native token standard for stablecoins, tokenized real-world assets and other fungible tokens, enabling issuers to create assets without custom token contracts, Base said. On July 16, Base creator Jesse Pollak said the network had made a “wrong bet” by focusing on creator, content and messaging apps and had fallen behind in areas including prediction markets and perpetual futures.
What to watch next
Adoption will show whether Cobalt’s issuer controls meet regulated requirements in practice. Signals to track include: new B20 asset launches that enable stacked compliance checks; issuer use of corporate-action display updates; protocol integrations of Validity Transactions; and any policy guidance from Base on how administrators are authorized for transfers and how privacy until inclusion is enforced technically.

🧠 HafidWatch Take
The success of Base’s new approach will depend largely on how effectively issuer controls satisfy regulatory demands without sacrificing too much decentralization. A critical tipping point will be whether multi-rule compliance mechanisms and optional admin transfers can gain enough trust to unlock widespread use of tokenized real-world assets and stablecoins. If these features prove both secure and user-friendly, Base may establish itself as the leading platform for compliant onchain finance.
