“This is big,” Phil Kwok, cofounder of crypto education and rewards app EasyA, posted to X. “I can’t tell you the number of times our app’s been flagged for compliance … simply because we mention crypto. This will pave the way for a flood of blockchain adoption.”

This week, a judge in the long-running legal battle between Apple and Fortnite maker Epic Games ruled Apple can no longer collect fees on purchases made outside of iOS apps or restrict how developers can direct users to make purchases outside of apps.

Apple said it intends to appeal the order, which is currently only in force in the United States.

Following the ruling, Apple emailed iOS developers, telling them “apps on the U.S. storefront are [no longer] prohibited from including buttons, external links, or other calls to action when allowing users to browse [crypto-based non-fungible token] NFT collections owned by others.”

“The prohibition on encouraging users to use a purchasing method other than in-app purchase does not apply on the U.S. storefront,” the email added.

Crypto developers have cheered the update, with some predicting it will help spur a bitcoin price and wider crypto market boom.

The loosened restrictions could trigger a “generational golden consumer crypto bull run,” Wojciech Kulikowski, a software engineer at Farcaster, wrote on the decentralized media protocol, adding in comments to Decrypt that it ”will allow for more experimentation with crypto-native mobile apps that were previously often blocked from Apple [iOS] App Store.”

“Apps can accept crypto payments rather than routing through the Apple app store (with a 30% fee),” one pseudonymous crypto software developer posted to X. “This is huge for integration with mobile wallets where users can spend their crypto directly (USDC, ETH, SOL, etc) without having to pay extra fees.”
