Zipper (Protocol 27) Mainnet

Medium6.5

◆ Description

Stellar protocol upgrade 27 (Zipper) is live on Mainnet, enabling authentication delegation and address-bound smart contract credentials for custom accounts.

◆ Why it matters

Stellar's protocol 27 ships on mainnet, activating authentication delegation and address-bound smart contract credentials for custom accounts. The upgrade is a concrete capability delivery, not a market-structure change, so its effect on XLM is confirmation of expected network progress rather than a thesis-level re-rate. Active Stellar followers track this; broader market impact stays contained.
