Base Completes Cobalt Upgrade, Enhances Tools for Tokenized Assets Management
Base has activated the Cobalt upgrade, the network's third major update on the Ethereum layer-2 platform, introducing conditional transactions and enhanced issuer controls for tokenized assets as it strengthens its focus on onchain finance. The upgrade expands the B20 token standard to enable multiple compliance checks on single assets, supports corporate actions without altering token supply, and grants authorized administrators control over token transfers without holder consent. This marks a pivotal step for Base in enabling traditional financial products onchain.
Enhancements to Tokenized Assets Through Cobalt Upgrade
The Cobalt upgrade expands the B20 token standard on Base by enabling issuers to apply multiple compliance verifications to a single asset. For instance, recipients can be required to pass identity verification, qualify as accredited investors, and not appear on sanctions lists simultaneously.
Issuers can now schedule corporate actions such as stock splits. This update alters the number of shares displayed in wallets and applications without minting or burning tokens or adjusting the underlying balances.
An additional feature allows authorized administrators to transfer tokens from a holder’s wallet without the holder's consent, attaching a public note to each transfer. Issuers have the discretion to activate this feature and assign administrators, while Base itself cannot initiate such transfers.
Validity Transactions: Conditional Execution for Greater Trade Control
Cobalt introduces Validity Transactions, which allow users to submit transactions that only become eligible for inclusion in the blockchain when specified onchain conditions are met. This functionality grants traders enhanced control over the timing and parameters of their transactions.
For example, a trader could submit a swap transaction that activates only if an asset reaches a predetermined price before a specified block deadline. Base holds these transactions and continuously evaluates the trigger conditions against the blockchain state as blocks are produced. The system also enables the transactions to remain private until inclusion in a block.
Base’s Reinforced Commitment to Onchain Finance
The Cobalt upgrade builds upon Base's ongoing push into tokenized finance. On July 8, Base activated the B20 token standard as a native protocol for stablecoins, tokenized real-world assets, and other fungible tokens, removing the need for issuers to create custom token contracts.
On July 16, Base founder Jesse Pollak admitted the network had made a strategic misstep by focusing primarily on creator, content, and messaging applications, which caused the platform to lag behind in sectors like prediction markets and perpetual futures.
Pollak declared an intention to reorient the project towards financial applications, including trading and payments, aiming to evolve Base into a blockchain for global finance.
Following this shift, the B20 standard found a prominent use case when Coinbase launched tokenized U.S. stocks—including Apple, Nvidia, Meta, and Alphabet—on Base as B20 tokens on August 25.
Future Technical Developments for Base Network
In the coming months, Base plans to reduce block times from two seconds to 200 milliseconds, drastically improving transaction throughput and latency.
The protocol will gain support for sponsored transaction fees and bundled transactions, facilitating a smoother and more flexible user experience.
Additionally, Base will incorporate certain technical improvements intended for Ethereum’s upcoming Glamsterdam upgrade to enhance network compatibility and performance.
Why it matters
The Cobalt upgrade marks a critical advancement for Base’s ambition to merge traditional finance with blockchain infrastructure. By expanding compliance and administrative capabilities through the B20 standard, issuers gain robust tools to safely issue tokenized securities under regulatory frameworks. The addition of conditional transactions enhances trade management and can preserve transaction privacy in specific circumstances. This upgrade aligns with Base’s broader strategic pivot towards financial applications, as acknowledged by the founder’s admission of a previous misplaced focus on creator-focused apps. Real-world deployments, like Coinbase’s tokenized stock offerings, illustrate the network’s growing utility in global finance ecosystems.
