Blast API Shutdown: Migrate to OnFinality for Reliable RPC Infrastructure and 50% Off
We explore how the Blast API shutdown affects developers, why OnFinality is the best migration alternative, and how you can move your endpoints in minutes while enjoying 50% off and free migration support.
Introduction
When Alchemy announced its acquisition of Blast API, it sparked uncertainty across the Web3 developer ecosystem. Blast API is shutting down on October 31st and builders who relied on Blast for RPC connections now face questions about pricing changes, support continuity, and long-term infrastructure stability.
If you are one of them, you are not alone. Many developers are exploring Blast API migration to trusted multi-chain providers like OnFinality. Let’s explore how the Blast API shutdown affects developers, why OnFinality is the best migration alternative, and how you can move your endpoints in minutes while enjoying 50% off and free migration support.
Why the Blast API Shutdown Matters for Developers
When an RPC provider goes offline, dApps lose their gateway to the blockchain. This means failed transactions, non-responsive apps, and broken user experiences.
Blast API’s shutdown leaves developers only a few days to transition their infrastructure. Migrating early ensures continuity, avoids downtime, and keeps your dApp running smoothly.
With OnFinality’s reliable RPC infrastructure, builders can quickly generate endpoints, connect to over 100 supported networks, and continue scaling without disruption.
