Base activated the B20 native token standard on July 8, 2026, as part of its Beryl upgrade cycle. The new standard is implemented as a precompile inside the node, not as a user-deployed Solidity contract, and mirrors ERC-20 function selectors for wallet and indexer compatibility. Early on-chain activity after launch skewed heavily toward memecoins, with no real-world assets (RWAs) or stablecoins observed in the first sample.
What B20 Brings to the Table
B20 includes an Issuer Toolkit with built-in features that go beyond basic token creation. Issuers get role-based access, transfer policies such as allowlists and blocklists, supply caps, and a freeze-and-seize function called burnBlocked. The standard also supports optional on-chain memos and ERC-2612 permit for gasless approvals. Tokens have deterministic addresses starting with 0xB200…, created via a factory at 0xB20f000000000000000000000000000000000000.
Early Activity: Memecoins, Not Real-World Assets
Despite the compliance-oriented toolkit, the first wave of B20 tokens were almost entirely memecoins. No stablecoins or tokenized real-world assets appeared in the initial on-chain data. That may shift as more projects explore the standard, but for now the launch has attracted speculative rather than institutional activity.
How B20 Differs from ERC-20
The execution model is a departure from ERC-20. Instead of each issuer deploying a custom contract, the chain ships the core logic and issuers flip switches to configure their token. That potentially offers leaner gas execution via the precompile compared to typical ERC-20 contracts. It also reduces the audit surface because the shared native logic is maintained by the chain, not by individual projects that each need their own security review.
What’s Next: Fee Payments and Cobalt
Base’s roadmap includes a planned ability to pay fees in B20 tokens, referenced in Cobalt planning notes. That would let users transact without holding ETH for gas, a feature that could broaden adoption. No timeline for Cobalt has been announced.
