<p>Stellar's (<a href="https://x.com/StellarOrg" rel="noopener noreferrer nofollow">@StellarOrg</a>) Protocol 28, codenamed Adapter, is now live on mainnet following a validator vote on September 16, 2026. <cite>Validators approved the upgrade on September 16, 2026, with Adapter going active within hours of the vote.</cite><cite>This marks the official rollout, following a testnet run back in August.</cite></p>
<p><cite>It is a builder-focused release: most of what is inside makes life easier for the people writing smart contracts on Stellar, while a change under the hood helps the network reach consensus faster as it continues to scale.</cite></p>
<h2 id="what-the-upgrade-actually-changes">What the Upgrade Actually Changes</h2>
<p>Adapter bundles three distinct technical proposals. The most significant infrastructure change, known as CAP-83, addresses a long-standing bottleneck in the consensus process. <cite>Right now, validators need a complete transaction set before confirming the next ledger. CAP-83 lets validators start voting before the full set arrives,</cite> keeping consensus moving even when transaction data is slow to propagate across the network.</p>
<p>On the smart contract side, <cite>CAP-85 allows groups of smart contracts that share code to upgrade together in one move, instead of updating each one by one.</cite><cite>It introduces a shared, updatable code reference that multiple contracts can point back to. Change that single reference, and every connected contract upgrades at the same moment, no matter how many there are.</cite> The third proposal, CAP-86, eases migration of contract data during structure updates, reducing friction for developers managing evolving applications.</p>
<p><cite>The full performance gains will be phased in after mainnet as parallel transaction-set downloading is gradually enabled.</cite> Stellar says the upgrade is designed to support larger and more complex applications on the network.</p>
<p>For ordinary users, the changes are largely invisible at the surface level. <cite>For everyday users, little changes at first glance. Stellar payment systems still move the same way. But behind the scenes, the network just got a meaningful boost in how it handles growth.</cite></p>
