Giugliano Hard Fork

Polygon will deploy its Giugliano hard fork on April 8 to reduce transaction finality time by roughly two seconds, a technical improvement that matters to institutional traders and developers managing execution latency and settlement risk on a Layer 2 network processing 119 million monthly transactions. The upgrade is the first concrete step in Polygon’s “Gigagas” roadmap, which targets 1,000 transactions per second by July and 5,000 TPS by October, metrics that will determine whether the chain can compete for institutional liquidity without the gas price volatility that has characterized its recent activity.

• Polygon Foundation confirmed April 8 activation at block 85,268,500, roughly 2:00 PM UTC, with finality improvements tested on Amoy testnet.
• Network averaged 119 million monthly transactions and 7.4 million active users through 2025, spiking to 183 million transactions by December.
• Giugliano is phase one of multi-quarter scaling plan targeting 1,000 TPS by July and 5,000 TPS by October via Agglayer integration.

• ~2 sec reduction in finality time observed during Amoy testnet validation phase
• 119M average monthly transactions across 2025 compared to 183M in December
• 1,000 TPS throughput target by July, measured against current network baseline

Polygon will activate the Giugliano hard fork on mainnet on April 8, introducing modifications designed to accelerate how quickly transactions achieve finality, the irreversible confirmation point critical for both retail users and institutional settlement operations. The upgrade will go live at approximately 2:00 PM UTC at block 85,268,500, according to the Polygon Foundation.

The core change enables block producers to signal new blocks earlier in the consensus sequence, a technical adjustment expected to compress confirmation latency across the network. Testing on the Amoy testnet demonstrated a reduction of roughly two seconds in finality time, though the foundation has not disclosed whether this improvement will hold uniformly across varying network load conditions.

For infrastructure operators and market participants, the upgrade introduces operational requirements and architectural changes that demand immediate attention. Node operators must upgrade Bor to version 2.7.0 or Erigon to version 3.5.0 before the activation block; nodes that fail to update will fall out of sync with the network post-fork.

The Giugliano update also embeds fee-related parameters directly into block headers and adds new RPC endpoints for fee data access, streamlining how developers and trading platforms query transaction cost information. These changes are particularly relevant to institutional users managing algorithmic execution strategies, where latency and cost transparency directly affect order routing decisions.

Giugliano Cuts Finality Time as Part of Broader Scaling Strategy

The hard fork is not a standalone improvement but rather the opening phase of Polygon’s “Gigagas” roadmap, a multi-quarter initiative to systematically increase network throughput and efficiency. By July, the roadmap targets 1,000 transactions per second alongside finality times of approximately five seconds and more predictable fee structure.

By October, Polygon aims to scale beyond 5,000 TPS, unlocking smoother cross-chain liquidity through integration with Agglayer, the foundation’s proposed interoperability protocol. The long-term vision includes near-instant finality with one-second block times and zero chain reorganizations, eventually supporting up to 100,000 TPS.

The timing of the roadmap is strategically significant. Polygon’s current transaction throughput, while steady, has not scaled to the levels required to materially reduce gas prices or attract high-frequency institutional flow that demands sub-second settlement.

At the July checkpoint, roughly three months after Giugliano’s deployment, the market will have concrete data on whether the technical improvements translate to real-world throughput gains. This creates a measurable milestone for institutional investors to evaluate the chain’s credibility relative to competitors like Arbitrum and Optimism, which have pursued different fee reduction strategies.

The roadmap also suggests Polygon is targeting a specific operational envelope: five-second finality paired with lower volatility in transaction fees would position the chain for payment and trading applications that tolerate modest settlement delays but require fee predictability.

Network Activity Jumped 57% in Q4 2025, Then Stabilized

Polygon’s activity metrics provide context for why this upgrade is being prioritized now. According to analysis by CoinGecko, the network averaged roughly 119 million transactions per month through 2025, with monthly volumes ranging between 85 million and 110 million. Daily active user counts remained stable between 6 million and 8 million during the same period.

However, in the final quarter of 2025, transaction volume accelerated sharply: October recorded 116 million transactions, rising to 183 million by December, a 58% increase in just three months.

That spike was driven primarily by payment applications and derivatives platforms, particularly Polymarket’s trading activity. The surge elevated network revenue to its highest level since early 2023 in January 2026, validating demand for high-volume applications on Polygon.

However, active user counts declined in early 2026 despite sustained high transaction volumes, suggesting that transaction growth was driven by a smaller cohort of power users and bots rather than broad user adoption, a pattern typical of DeFi trading and prediction market cycles.

For institutional investors, this metric split is significant: high transaction volume on fewer users implies that network security and finality reliability matter more than ever, because concentrated usage creates larger settlement risks if nodes fall out of sync.

The revenue surge also underscores the fragility of Polygon’s economic model. Network revenue is volatile and episodic, tied to specific application launches and trading cycles rather than sustainable demand. The Giugliano upgrade, by reducing finality time, is intended to remove a technical friction point that has historically prevented time-sensitive applications from migrating to Polygon.

Faster finality means higher-frequency trading bots and payment processors can operate with lower reserves and lower operational overhead, potentially attracting more sustained institutional flow.

Node Operator Readiness and Network Coordination Risk

A critical operational question remains unresolved: whether node operators will upgrade their infrastructure in time. Hard forks introduce coordination risk. If a significant portion of validators or full node operators fail to upgrade before block 85,268,500, the network could split into incompatible chains, causing settlement failures and temporarily halting affected applications.

Polygon has published upgrade requirements, Bor 2.7.0 or Erigon 3.5.0, giving operators roughly six weeks to validate and deploy the change in production environments.

The stakes are particularly high for institutional staking operations and exchanges that run full nodes. An exchange that fails to upgrade could temporarily fall out of sync, causing withdrawal processing delays that could trigger user complaints and competitive disadvantage. This creates an implicit deadline for exchange operators and large node operators to complete testing and deployment.

Polygon Foundation has not disclosed whether it has contacted major node operators individually or published an estimated percentage of the network that has already upgraded, a typical pre-fork transparency metric in Ethereum and Solana governance.

The absence of publicly available upgrade readiness data is itself a warning signal: it suggests either weak adoption monitoring or a deliberate choice to avoid drawing attention to coordination risk.

Workforce Contraction and Execution Credibility

The timing of the Giugliano deployment also follows organizational turbulence at Polygon Labs, the foundation’s development arm. In early 2026, Polygon Labs cut 30% of its workforce as part of a restructuring effort, continuing a pattern of reductions that began in 2023 and 2024.

For institutional investors, workforce reductions raise questions about the organization’s capacity to execute on an ambitious roadmap that requires not only shipping Giugliano on schedule but also delivering 5x throughput scaling by October and integrating Agglayer by then as well.

The April 8 date is a test of execution credibility. If Giugliano deploys on schedule and achieves the advertised finality improvements in mainnet conditions, it will validate that Polygon can deliver meaningful technical upgrades despite organizational constraints. If the fork is
