The history of Avalanche’s subnet experiment
Avalanche has transitioned from high-barrier subnets requiring 2,000 AVAX to sovereign Layer-1 networks via the Etna upgrade. This shift enabled massive institutional adoption, such as Japan's Progmat migrating over $2 billion in tokenized assets to a dedicated L1.
In 2022, the market capitalization of Avalanche exceeded 5 billion dollars. During this period, DeFi Kingdoms launched DFK Chain as an EVM compatible blockchain using subnet technology to manage JEWEL as the network gas token. This model required validators to stake 2,000 AVAX to join a subnet while maintaining a total JEWEL supply of 500 million tokens. Developers used Subnet-EVM to build these environments, but the repository eventually reached deprecation as development moved to AvalancheGo. You likely remember the high entry barriers that defined this era of network participation. While projects like DeFi Kingdoms used incentives like the Avalanche Multiverse program to attract users, the original subnet architecture tied validators to the Primary Network. Users also encountered the error "strconv.ParseUint: parsing "": invalid syntax" when attempting to create a subnet via the Avalanche CLI.
Architecture shifts from subnets to L1s
The Etna upgrade in December 2024 replaced subnets with sovereign Layer-1 networks and gave L1s independent validator logic, governance rules, and execution parameters while removing the 2,000 AVAX staking requirement. This architecture reduces deployment costs for these chains by over 99 percent. It also removes the need for validators to sync with the Primary Network, replacing that obligation with a smaller continuous validation fee. This update introduces Interchain Messaging to enable L1s to send assets and data to each other without external bridges. The upgrade also introduced ACP-77, which allows L1 chains to determine their own staking and validator policies through custom management. The upgrade also incorporated ACP-103, which changed the fee system of the P-Chain and X-Chain from fixed costs to variable costs based on network demand. This shift moves the ecosystem toward a "many-chain" design through horizontal scaling across specialized execution environments.
| Deployment Metric | Subnet Model (Pre-Etna) | L1 Model (Post-Etna) |
|---|---|---|
| Staking Requirement | 2,000 AVAX | Continuous fee |
| Deployment Cost | High | 99 percent reduction |
| Governance | Primary Network linked | Independent |
Corporate adoption in 2026
Institutional adoption characterizes the current environment. Japan’s Progmat migrated over $2 billion in tokenized real estate assets and corporate bonds to a dedicated Avalanche L1, reporting a value of more than JPY 452 billion as of July 2026. KB Kookmin Card in South Korea builds a hybrid stablecoin payment system on an L1 to allow customers to pay with stablecoins or credit on a single card. Fosun Wealth launched FUSD, an Asian yield-bearing RWA-backed stablecoin, on the C-Chain to provide native yield for institutional investors. Galaxy tokenized its first CLO on the network with a $50 million anchor from Grove.
Additionally, the Avalanche Foundation manages the Retro9000 C-Chain Round, which has awarded over $1.25 million in grants. The program uses AVAX burned through gas fees to score the top 40 projects per round and includes a 1.5x multiplier for new projects and a 10x multiplier for Build Games Stage 2 MVP projects. In June 2026, 29 organizations joined the Avalanche Payments Collective. In September 2026, the payments firm TIS announced a multi-token platform developed with AvaCloud for companies issuing and settling stablecoins and tokenized assets. The Foundation also provides a $1 million prize pool through the Build Games competition, and DeFi Kingdoms previously used $15 million in incentives to support its Crystalvale launch on DFK Chain. This shift moves the ecosystem focus from "who built" to "what is being used". Does the removal of shared bottlenecks guarantee permanent stability for these financial rails?
