Cosmos-native layer-1 blockchain Canto has become the latest chain to migrate to Ethereum as a layer 2 zero-knowledge rollup, after another layer-1 blockchain, Astar, announced similar plans moving from the Polkadot ecosystem to Ethereum.
Canto is a permissionless general-purpose blockchain, which is Ethereum Virtual Machine (EVM)-compatible with aims to onboard the traditional financial sector to decentralized finance applications.
Upon an official agreement reached by Canto Commons — a framework where contributors coordinate ideas and solutions to the protocol — its core developers will build a ZK rollup on Ethereum’s second layer, Polygon Labs explained on Sept. 18:
“By leveraging a shared ZK bridge, Canto will eventually tap the liquidity of a unified Polygon ecosystem with easy access to Ethereum.”
Polygon Labs said Canto will “inherit” Ethereum’s security, enabling more decentralization and trustless guarantees when bridging assets over:
“User security comes by way of a best-in-class and in-production ZK prover, meaning community security is ensured by cryptography and inherited from Ethereum, rather than the social-economic incentives of fraud proofs.”
Neofinance at scale – Canto is migrating to a ZK-powered Ethereum L2, built with @0xPolygon CDK.

There will be no changes to Canto’s validators or staking system, Polygon Labs added.
Canto follows moves from Astar
Canto joins the likes of Astar, Gnosis Pay, Palm and IDEX to have announced plans to build ZK layer 2s using Polygon’s Chain Development Kit in recent months, according to Polygon Labs co-founder Sandeep Nailwal.
On Sept. 13, the Astar team announced it will soon begin building its own Ethereum layer-2 scaling solution, named Astar ZK-Ethereum Virtual Machine (EVM), also using Polygon’s CDK.
“We are building a trustless bridge to Ethereum with high EVM equivalency right out-of-the-box, so dApp developers can use existing tools to build solutions across our entire ecosystem,” the Astar team explained in a Sept. 14 statement.
I’m excited to welcome @AstarNetwork, the leading @Polkadot chain to Ethereum. They are going to launch a zkEVM chain using @0xPolygon CDK, an Ethereum L2 secured by ZK!@AstarNetwork is the leading blockchain of…
