Polygon to Activate Giugliano Hard Fork on April 8 for Faster Finality

• Polygon is set to activate its Giugliano hard fork on mainnet on April 8 at roughly 2:00 p.m. UTC.
• The upgrade is designed to improve finality speed and add new fee-related data directly into block headers.

Polygon is preparing to push its Giugliano hard fork to mainnet this week, with the upgrade scheduled for Wednesday as the network works to reduce confirmation times and refine how fee data is handled onchain.

The Polygon Foundation said Monday that the hard fork will activate at block 85,268,500, which it expects to occur at around 2:00 p.m. UTC on April 8. The update follows a testnet run on Amoy last month and now moves into production at a time when infrastructure efficiency is getting more attention again across scaling networks.

Earlier block announcements target faster settlement

The core change in the Giugliano upgrade is finality. Polygon said the hard fork will let block producers announce blocks earlier, a shift intended to make the network reach finality faster.

That may sound technical, and it is, but the practical point is fairly straightforward. Faster finality reduces the waiting period before transactions are considered settled, which matters for traders, applications and infrastructure providers that depend on predictable confirmation times.

In networks competing on speed and user experience, these smaller protocol changes tend to matter more than they first appear to. They affect how exchanges, wallets and applications interact with the chain day to day.

Fee data moves closer to the protocol layer

The upgrade also introduces fee parameters directly into block headers and adds new RPC support for fee data. In effect, Polygon is making fee-related information easier to surface and more native to the network’s own data structure.

That could help node operators, developers and external services access fee information more cleanly, without relying on workarounds or fragmented tooling. It is the sort of back-end improvement users may never notice directly, though they usually notice when it is missing.

Giugliano is not being framed as a sweeping redesign. It looks more like a targeted protocol adjustment, focused on transaction finality and fee visibility. Still, those are two areas that shape the network’s basic performance, and Polygon is clearly treating them as worth tightening now.
