As applications scale, their needs often exceed what general-purpose blockchains can offer. Avalanche L1s – custom, sovereign chains – address this by letting teams control their infrastructure while remaining interoperable within the broader Avalanche ecosystem. Unlike shared networks that extract value without flexibility, these appchains are tailored for specific use cases.
Historically, launching a custom chain was costly and complex. Avalanche’s Etna upgrade changed that. By removing the requirement to validate the Primary Network and lowering staking costs, it opened the door for a wider range of developers and institutions to build specialized, compliant networks.
For enterprises, this is critical. Etna enables fully private chains with customizable validation and execution, making it possible to meet regulatory requirements without sacrificing performance. Major players like J.P. Morgan with Kinexys and MapleStory Universe are already building on Avalanche L1s to support use cases ranging from tokenized finance to gaming infrastructure.
Avalanche L1s’ supercharged architecture shifts the balance – giving teams ownership over their ecosystems and a clearer path to scale. Instead of adapting to rigid infrastructure, they can now build around their own logic, needs, and value capture.
