Base shipped B20 with its Beryl upgrade in mid-2026, and the name has confused people ever since — some think it's Base's version of BEP-20, some think it's a Base coin. Here's what it actually is, what it isn't, and what a token issuer should do about it.
What is the B20 token standard?
B20 is a native token issuance standard introduced by Base's Beryl network upgrade (mainnet, June 25, 2026), designed for issuing tokens — with stablecoins and tokenized real-world assets as the headline use cases — at the chain level rather than purely at the contract level. It arrived as part of Base's 2026 strategy push toward tokenized markets and stablecoin payments (Base's own framing in its 2026 strategy), and it's documented first-hand in the Beryl announcement. B20 is new, and its public documentation is still maturing — this page cites only what Base has published and gets updated as the picture fills in; anything you read about B20 that doesn't link a primary source deserves suspicion.
Is B20 a Base coin or airdrop?
No — B20 is a token standard, not a token, and Base still has no network coin as of August 2026. This is the confusion worth killing directly: "B20" names a format for issuing tokens on Base, the way "ERC-20" names a format on Ethereum. It is not a coin you can buy, claim, or get airdropped. Base's only statement about a network token remains the September 2025 BaseCamp announcement that it was "beginning to explore" one, with nothing launched since. Gas on Base is ETH. Anyone selling "$B20" or a "Base token presale" is running a scam on the confusion.
Should your project issue as B20 or ERC-20?
For a standard project, community, or governance token, ERC-20 remains the default and the safe choice; B20 is aimed at issuers of stablecoins and tokenized real-world assets that benefit from chain-level integration. The practical case for ERC-20 today is overwhelming for most launches: every wallet, DEX, screener, locker, and tool on Base speaks ERC-20 fluently — including the entire trust stack this hub covers (creation, locks, vesting, distribution). A new standard's early adopters trade tooling compatibility for chain-native features, and that trade only makes sense when the features are your product — which for a stablecoin issuer or RWA platform they may well be. If that's you, work from Base's primary documentation and expect the tooling ecosystem to catch up behind the standard, not ahead of it.
What should token issuers watch as B20 matures?
Three things decide whether B20 matters to ordinary projects: tooling adoption, DEX and wallet support, and whether Base's tokenized-markets push brings issuance volume. Watch whether the major Base DEXes and wallets handle B20 assets as first-class citizens; whether lockers, vesting platforms, and screeners extend support (Team Finance supports ERC-20 across its Base products today — B20 support will follow the standard's real-world adoption, not its press cycle); and whether Coinbase's tokenized-equities and stablecoin ambitions on Base actually route through B20 issuance. If those three land, B20 becomes relevant to more than institutions. Until then, the boring advice stands: launch ERC-20, lock the pool, and let standards wars resolve without your treasury as a test case.
FAQ
When did B20 launch? With the Beryl upgrade, activated on Base mainnet June 25, 2026 — Base's second independent network upgrade of 2026, after Azul in May.
Is B20 the same as BEP-20? No. BEP-20 is BNB Chain's ERC-20-equivalent contract standard. B20 is Base's native issuance standard aimed at stablecoins and tokenized assets at chain level. The similar names are an accident of naming conventions, not a technical relationship.
Can I lock liquidity for a B20 token with Team Finance? Team Finance's Base products support ERC-20 tokens and Uniswap v2/v3 LP positions today. For B20 assets, check current support at team.finance before planning a launch around it — and expect the broader tooling ecosystem to lag the standard initially.
Does B20 replace ERC-20 on Base? No. Base is EVM-equivalent and ERC-20 remains fully supported and dominant; B20 adds a chain-native issuance path alongside it, aimed at a different class of issuer.
Where's the authoritative B20 documentation? Base's primary sources: the Beryl announcement at blog.base.dev and docs.base.org as documentation expands. Prefer those over any third-party explainer — including this one.
