Coinbase-incubated layer-2 network, Base, is ready to roll-out its highly-anticipated Berly upgrade on June 25. The mainnet upgrade promises an array of new offerings, including the B20 token standard, lower withdrawal time from the Ethereum network, and improved node performance.
Beryl upgrade finally brings the B20 token standard
Beryl is Base’s second major upgrade arriving just 4 weeks after the network’s previous Azul upgrade. Perhaps the headline change of the Beryl upgrade is the B20 native token standard. The B20 token standard can be leveraged to issue stablecoins, tokenized real-world assets (RWAs), and other on-chain tokens.
It should be highlighted that the Beryl upgrade is already live on Base’s Sepolia testnet. The B20 token standard is a precompiled contract, meaning its logic runs natively in the node software, which is written in Rust language.
At the same time, it is also fully ERC-20 compatible. Notably, the B20 token standard has 2 variants – ‘Asset,’ which is a general-purpose variant with rebasing support, and ‘Stablecoin,’ which is a fixed 6-decimal precision token variant with issuer-defined currency codes.
Since it follows the ERC-20 token standard, all tokens created under the B20 standard can work seamlessly with existing wallets, exchanges, explorers, and on-chain protocols.
In addition, the B20 token standard comes with an issuer toolkit with controls for minting, burning, pausing, supply caps, signature based approvals, and a lot more. According to Base, the toolkit has already been thoroughly audited by Base and Spearbit.
The announcement also mentions some of the upcoming features on the B20 token standard, including the ability to pay transaction fees in your own token, creating unique deposit addresses that forward to a shared account, and as much as 50 percent cheaper token transfers.
Besides rolling out the B20 token standard, the Beryl upgrade also significantly reduces the time it takes to withdraw digital assets from Base to Ethereum via the single-proof path, from 7 days to 5 days. The upgrade leaves Azul’s 1-day dual-proof fast track unchanged.
Base experiencing strong stablecoin growth
Looking at Base’s stablecoin reserves, USDC accounts for 85 to 90 percent of total stablecoin supply on the network. Since the network’s launch, stablecoin volumes processed on the network have reached multi-trillion dollar figures.
Back in June 2025, Canadian e-commerce platform Shopify integrated USDC payments on Base. Similarly, Stripe followed by enabling USDC subscriptions on Base. On May 4, CADD, the first Canadian stablecoin went live on Base.
