<p><strong>Base, the Ethereum layer-2 network incubated by Coinbase, is targeting June 25 for the mainnet launch of its Beryl upgrade, which introduces the B20 token standard to the chain.</strong></p>
<p>The announcement, shared via <a href="https://x.com/buildonbase/article/2067693904909189141" rel="noopener noreferrer nofollow">Base's official X account</a>, frames the date as a target rather than a confirmed deadline. The Beryl upgrade pairs a network-level enhancement with a new token standard, bundling infrastructure changes and developer tooling into a single rollout.</p>
<h2 id="what-the-beryl-upgrade-and-b20-token-standard-bring-to-base">What the Beryl upgrade and B20 token standard bring to Base</h2>
<p>The Beryl upgrade represents Base's next named network upgrade, following the project's pattern of incremental improvements to its rollup infrastructure. The B20 token standard ships alongside it, giving developers a new framework for issuing tokens on the chain.</p>
<p>Base's <a href="https://blog.base.dev/introducing-base-beryl" rel="noopener noreferrer nofollow">developer blog details the Beryl upgrade</a> as a coordinated effort tying protocol-level changes to the introduction of B20. By packaging both in a single mainnet launch, Base aims to reduce the migration burden for builders who would otherwise need to adapt to sequential updates.</p>
<p>The pairing matters because token standards define how assets behave across wallets, exchanges, and decentralized applications. A new standard launched alongside a network upgrade means developers can build on both simultaneously rather than retrofitting existing contracts. This approach echoes trends seen across layer-2 networks, where projects like Base compete on developer experience as much as throughput, a dynamic visible in how <a rel="noopener noreferrer nofollow">exchanges are expanding support for tokenized asset standards</a> across multiple chains.</p>
<h2 id="who-should-watch-the-june-25-date">Who should watch the June 25 date</h2>
<p>Developers building on Base will need to assess compatibility with both the Beryl upgrade and the B20 standard before the target date. Token issuers evaluating Base as a launch chain now have a concrete timeline to plan around, though the "target" framing leaves room for delay.</p>
<p>For users, the upgrade could affect transaction processing and the types of tokens available on Base-native applications. The rollout also carries implications for the broader layer-2 ecosystem, where <a rel="noopener noreferrer nofollow">institutional interest in Ethereum-adjacent infrastructure</a> continues to grow.</p>
<p>Market participants tracking Base activity may look to on-chain metrics in the days surrounding June 25 to gauge adoption. <a href="https://l2beat.com/scaling/projects/base" rel="noopener noreferrer nofollow">L2Beat's Base overview</a> provides real-time data on the network's transaction volume and total value locked, offering a baseline for measuring any post-upgrade shifts.</p>
<p>The next milestone to watch is whether Base confirms June 25 as a hard date or signals any adjustment. Projects in the <a rel="noopener noreferrer nofollow">stablecoin</a> and <a rel="noopener noreferrer nofollow">institutional custody</a> spaces building on layer-2 networks will be particularly attentive, as upgrade timelines directly affect integration roadmaps.</p>
