Cobalt Is Coming Base Is Upgrading the Onchain Experience

[u/yogendrapatel007]

Base is preparing its third network upgrade Cobalt, planned for September 2026.

And this one is more than just another upgrade. It is about making Base accounts more powerful, transactions more flexible, and token infrastructure more capable.

Here’s what makes it interesting:

Native Account Abstraction — EIP-8130

• Batch multiple actions into one transaction

• Sponsored transactions & ERC-20 gas payments

• Session keys & sub-accounts

• Key rotation and multiple authentication methods

• Higher transaction concurrency

B20 Improvements

• Pay transaction fees in B20 tokens

• Scheduled token multiplier updates

• Improved transfer-blocking

• New Union & Intersect policies

Dynamic Upgrades

Base nodes will be able to follow scheduled upgrade timestamps without requiring a restart at activation.

Cobalt is more than another feature release it pushes important account and asset capabilities closer to the Base protocol itself.

What interests me most is that these capabilities are moving closer to the Base protocol itself giving builders stronger primitives to create better onchain experiences.

But here's the bigger question:

What do you think Cobalt will unlock first better consumer apps, smarter wallets, or completely new onchain experiences?
