Reducing fees from C-Chain to Evergreen Subnet: How Avalanche is Restructuring Institutional Blockchain Infrastructure

On December 16, 2024, the Avalanche network completed its largest technical upgrade since its mainnet launch in 2020—Avalanche9000 (also known as Etna Upgrade)—officially going live on the mainnet. The core change directly targets the cost structure: through the improved proposal ACP-77, validators no longer need to stake 2,000 AVAX to run subnets, but instead pay a continuous monthly fee of about 1.33 AVAX; simultaneously, via ACP-125, the base transaction fee on C-Chain was reduced from 25 nAVAX to 1 nAVAX, a decrease of approximately 96%.

In the following approximately 17 months, participation from traditional financial institutions increased significantly. In April 2026, Avalanche’s Evergreen subnet “Spruce” transitioned from testing to production environment, with participating institutions including T. Rowe Price (managing $1.6 trillion in assets), WisdomTree (issuer of ETFs with over $110 billion), Wellington Management (managing $1.3 trillion), and crypto market makers Cumberland. On May 11, 2026, JPMorgan’s Onyx Digital Assets and Apollo Global launched a tokenized portfolio management proof of concept on Avalanche Evergreen subnet, with WisdomTree providing the tokenized fund access layer. On April 29, 2026, Tassat migrated its bank-grade real-time settlement network Lynq to a dedicated Avalanche L1, serving over 30 institutional partners including B2C2, FalconX, Galaxy, and Wintermute.

The intersection of these events lies in: Avalanche9000 reducing the fundamental costs, while the Evergreen permissioned chain framework provides the compliance environment needed by institutions. The combination of these two forms the basic narrative of current Avalanche institutional private chains.

May 18, 2026: According to Gate data, AVAX was priced at $9.110, with a market cap of approximately $16k, and a 24-hour trading volume of about $247.3k.

Cost Restructuring: From 2,000 AVAX Staking to Monthly Payment of 1.33 AVAX

Before the Avalanche9000 upgrade, any team wishing to deploy an independent subnet on the network had to meet a staking requirement of 2,000 AVAX. Ava Labs founder Emin Gün Sirer revealed that this requirement implied validators needed to bear an upfront capital cost of about $50,000 to $100,000. This pricing model essentially served as a capital-intensive access mechanism, limiting subnet deployment to well-capitalized projects.

The upgraded model has undergone a fundamental change. Through ACP-77, validators no longer need to stake 2,000 AVAX to validate both the mainnet and subnets but can choose to validate only specific L1s. The new mechanism adopts a pay-as-you-go model: each validator pays a minimum monthly ongoing fee of about 1.33 AVAX, with the fee rate calculated at a minimum of 512 nAVAX per second.

Ava Labs Chief Product Officer Nick Mussallem stated at the launch: “Avalanche9000 reduces the deployment cost of an L1 by 99.9%. With hundreds of L1s being developed on testnets, we expect a large number of network launches in the coming months.”

This change means that subnet deployment shifts from a one-time high capital investment to predictable operational costs. At the AVAX price of about $9.11 in May 2026, 1.33 AVAX per month is roughly $12.12, with an annualized cost of about $145. In contrast, the previous staking requirement of 2,000 AVAX at the current price was approximately $18,220, with funds locked in.

From a cost modeling perspective, the cost reduction logic of Avalanche9000 impacts institutional decision-making in at least two dimensions. First, the controllability of compliance costs. In traditional private chain solutions, institutions need to build and maintain entire validator node infrastructure, incurring significant costs. Avalanche9000 compresses this cost into a monthly small AVAX fee model, allowing institutions to allocate more budget to business logic development rather than infrastructure maintenance. Second, the significantly lowered threshold for trial and error. When deploying a dedicated chain costs close to $100 per month, institutions can conduct small-scale proof-of-concept tests without huge upfront investments, directly accelerating the decision cycle from “assessment” to “testing.”

How Evergreen Permissioned Chains Win Institutional Trust

Evergreen is Avalanche’s permissioned chain framework designed for institutional scenarios, complementing rather than opposing the public chain environment. Evergreen subnets inherit Avalanche’s consensus mechanism at the technical level but impose clear compliance constraints at the access layer: validators must complete KYC verification, counterparties must pass whitelist review, and smart contracts can embed jurisdiction restrictions and asset class access rules.

Citibank has already conducted private market tokenization testing via Evergreen subnets. A report detailed how Citibank utilized Avalanche network testing blockchain infrastructure integrated with existing financial systems, and conducted on-chain transaction execution and settlement tests for various applications and assets on the Evergreen subnet “Spruce.” Additionally, Citibank collaborated with the Monetary Authority of Singapore (MAS) on Project Guardian, testing blockchain infrastructure for simulated foreign exchange trading on Avalanche Evergreen subnet, utilizing Avalanche Warp Messaging for cross-network communication.

Spruce subnet is a typical implementation of this architecture. Its participating institutions include traditional asset management giants like T. Rowe Price, and through support for ISO 20022 financial messaging standards, achieved message interoperability with existing financial infrastructure. These institutions tested different asset classes and applications on Spruce to evaluate the advantages of on-chain transaction execution and settlement.

The JPMorgan Onyx and Apollo proof of concept launched on May 11, 2026, further demonstrated Evergreen’s cross-network connectivity. The project operates on Avalanche Evergreen subnet, targeting the $400 billion opportunity in alternative assets. It was disclosed that Apollo and JPMorgan’s digital asset platform Onyx collaborated to reduce over 3,000 operational steps for wealth management institutions to just one automated process, enabling faster programmatic settlement that could lower portfolio fees by about 20%, and bringing a $400 billion annual revenue opportunity to the asset management industry. As of April 2026, JPMorgan Onyx reportedly processed nearly $900 billion in digital asset tokenization repurchase transactions since launch.

The design philosophy of the Evergreen framework can be summarized as “optional compliance”—institutions gain access control of private chains while retaining the technical pathway to connect to public chain liquidity, rather than choosing between “fully closed” and “fully open.” This architecture is forward-looking in the context of increasingly strict regulatory environments.

Efficiency Narrative, Narrative Pricing, and Regulatory Focus

Different market participants show distinct focus points regarding Avalanche’s institutional ecosystem narrative.

Institutional side: primarily efficiency narrative. JPMorgan and Apollo, in their proof of concept, positioned tokenized alternative assets as a $400 billion revenue opportunity, emphasizing how blockchain can reduce operational friction and administrative costs inherent in private equity, private credit, and other asset classes. This valuation aligns with prior forecasts by Citibank analysts on the tokenization market of financial assets.

Market side: significant narrative pricing effect. According to multiple crypto data platforms, AVAX’s price increased by approximately 26%-30% around the announcement of JPMorgan-Apollo’s proof of concept in May 2026. This indicates strong market willingness to price in the “institutional adoption” narrative. In contrast, the Avalanche9000 mainnet upgrade in December 2024 did not trigger similar price movements, suggesting that the market’s pricing efficiency for “technological upgrade” may be higher, while “institutional adoption” as a more scarce signal commands a higher narrative premium.

Technical observation: focus on sustainability. Some analysts note that although subnet deployment costs have significantly decreased, whether the growth in subnet numbers can translate into sustained AVAX consumption remains to be seen. The monthly payment of 1.33 AVAX per validator on each L1 constitutes a continuous demand for AVAX, but the demand scale depends on the absolute number of validators and the actual activity level of L1s.

Regulatory side: framework adaptability concerns. Ava Labs management emphasized in public interviews that clarity in US regulation is key to institutional confidence, and mentioned that the Avalanche ecosystem is adapting to evolving global regulations, including the EU MiCA framework and relevant US legislation.

Industry Impact: Four Major Changes in the Institutional Blockchain Landscape

The combined effect of Avalanche9000 and the Evergreen framework is reshaping the institutional blockchain landscape across multiple dimensions.

First, the economic model of institutional private chains is recalibrated. Previously, institutions faced a dilemma: using public chains involved regulatory uncertainty, while building private chains entailed high infrastructure and maintenance costs. Avalanche9000 compresses the annual cost of dedicated chains to a few hundred dollars, making “deploying a chain for a single business scenario” economically feasible. Ava Labs compares this model to a “sovereign blockchain environment”—where enterprises gain full autonomy over their blockchain infrastructure, rather than sharing a common platform.

Second, on-chain settlement network migration is accelerating. The Lynq migration case shows that institutions’ demand for “real-time settlement” has moved from conceptual discussion to actual deployment. By deploying on permissioned Avalanche L1, Tassat combines the advantages of public blockchains with the control, governance, and compliance environment required by regulated financial institutions. Post-migration, Lynq provides shared settlement layers for over 30 partners, including B2C2, FalconX, Galaxy, and Wintermute.

Third, the infrastructure for tokenized assets is taking shape. The assets managed by institutions on Spruce exceed $3 trillion, which itself serves as a stress test for tokenization infrastructure. If these institutions extend on-chain settlement and custody models tested in the pilot phase into actual asset management workflows, the impact on custody, compliance, and auditing services will be structural.

Fourth, the value capture path for AVAX tokens is expanding from a “gas consumption” logic to a “network service subscription” model. The ongoing validator fees on each L1 form the baseline demand for AVAX, while actual transaction activity on institutional subnets constitutes a floating demand layer. In Q1 2026, the daily active addresses on Avalanche C-Chain were about 527,000, providing empirical reference for network activity among institutional deployers.

Currently, Avalanche has over 70 active L1s, aiming for 200 by year-end. Different sources report varying counts of active L1s—The Avalanche Foundation lists over 50, while third-party statistics range from 61 to 133. The number of active addresses on C-Chain increased significantly in 2025. Gas consumption and token prices show some correlation, but causality remains cautious—rising gas may reflect increased network usage (fundamental support), or merely speculative activity (not a structural positive). Transaction activity of institutional subnets, operating in permissioned environments, cannot be directly tracked from public chain data, adding information asymmetry to the assessment of “institutional adoption’s actual impact on token demand.”

Conclusion

The economic significance of the Avalanche9000 upgrade lies not in “price reduction” itself but in how it alters the supply curve of dedicated blockchains—transforming the previously exclusive deployment capability for top-tier projects into a low-threshold service for developers and institutions. The Evergreen framework precisely directs this supply capacity toward the institutional market, using permissioned access and compliance tools to address the core concerns of traditional financial participants against public chains. Citibank completed private market tokenization and FX trading blockchain tests via Evergreen subnets; JPMorgan’s Onyx and Apollo’s tokenized portfolio proof of concept demonstrated cross-chain asset management feasibility; and institutions managing over $3 trillion in assets, including T. Rowe Price, WisdomTree, and Wellington Management, are testing on-chain settlement on Spruce. These events are essentially a vote for the “compliant chain + composability” technical route. Whether this narrative can evolve from proof of concept to scaled commercial infrastructure depends on the continued stacking of execution, regulation, and ecosystem network effects.
