The main trigger behind the volume increase is not evident, but some factors might have contributed. Stellar's third major protocol upgrade has taken place so far in 2026, with a corresponding rise in trader activity.
The 303% increase in volume for Stellar indicates a sudden surge in trader activity. Increased liquidity helps market participants carry out larger trades with less price slippage and promotes a healthier trading environment.
Zipper upgrade goes live
The Zipper (Protocol 27) has been deployed on Stellar's mainnet. The protocol upgrade introduces authentication delegation for custom accounts and address-bound smart contract address credentials.
The upgrade introduces authentication delegation for custom accounts ($CAP-0071-01), which adds a first-class protocol mechanism for custom (smart contract) accounts to delegate their authentication logic to other addresses. It also introduces two new host functions and a new credential type. These are, however, additive changes, with existing contracts and credential types remaining valid.
A new credential type introduced by the upgrade allows all delegated signers and their (potentially nested) signatures to be bundled into a single authorization entry. This eliminates the need for a separate authorization entry per delegated signer, reducing transaction size and simplifying simulation.
Address-bound Soroban address credentials ($CAP-0071-02) included in the upgrade introduce a new credential type that uses the same signature payload introduced in $CAP-0071-01.
