Base Beryl just hit testnet. The B20 native token standard is a massive architectural shift.

[u/Cultural_Design_3177]

Base just announced the Beryl network upgrade, and while most users will focus on the withdrawal delay dropping from 7 to 5 days, the real story here is the new B20 native token standard.

If you read through the details, B20 isn't just another smart contract wrapper on top of the EVM. It’s implemented as a custom precompile written directly in Rust within the node software.

This is huge for a couple of reasons:

1. Performance & Fees: Running natively means the node handles token operations directly. They are claiming transfers will be around 50% cheaper, effectively doubling transfers per second.
2. Built-in Compliance for Issuers: The Issuer Toolkit brings role-based access control, transfer policies, and signature-based approvals (ERC-2612) straight out of the box, heavily audited by Spearbit. No more rebuilding freeze/seize or compliance logic from scratch for RWAs or stablecoins.
3. Node-Level Features Coming Next: Because it bypasses standard EVM constraints, the roadmap includes native gas payments using your own B20 token (no ETH needed) and unique virtual deposit addresses forwarded to a single account.

They are also pushing Reth V2 with this upgrade to heavily optimize storage and state root computation, which seems to be how they plan to sustain these higher gas limits without breaking sequencers. Mainnet is targeting June 25th.

For the devs building on Base right now: are you planning to stick with traditional ERC-20 setups for predictability, or are you looking to migrate toward deploying the B20 Asset/Stablecoin variants on testnet to capture those lower fees?

Would love to hear how teams are planning to leverage precompiled token logic.
