AltLayer is an open and decentralized Rollup protocol. AltLayer brings together the novel idea of Restaked Rollups, which takes Rollups (derived from any Rollup stack, such as OP Stack, Arbitrum Orbit, Polygon CDK, ZK Stack, etc.) and provides them with enhanced security, decentralization, interoperability Security and cryptoeconomics quickly establish finality by leveraging heavy staking mechanisms. ALT is AltLayer's native utility token, used for economic bonds, governance, protocol incentives, and protocol fees.

Solana switched on its Alpenglow upgrade on October 21, 2026, replacing the way its validators agree that a transaction is final. Validators are the computers that run the network, and finality is the point where a transaction can no longer be reversed.

Stablecoin payments reached $482 billion from January through September 2026, up 45% from the same period in 2025.
At its core, AltLayer simplifies rollup creation and deployment for developers.

Enter AltLayer (ALT), a decentralized protocol that takes rollups to the next level with its unique concept of "restaked rollups."
