Frequently asked questions

zkLink Nova Sepolia Testnet is the public testing network for zkLink Nova—an Ethereum-secured aggregated ZK layer that unifies liquidity and state across multiple L2 rollups—using Sepolia ETH as the native gas. It’s used to deploy and validate EVM smart contracts and cross-rollup dApps (DEXs, perps, payments, NFT apps) that bridge and settle across connected L2s with a single interface. Testnet performance metrics (avg gas cost, block time, TPS, and daily activity) fluctuate with load; fees are paid in faucet Sepolia ETH and confirmations finalize in seconds via batch proofs—check the official explorer for live figures.

zkLink Nova is unique because it provides a ZK-verified aggregated layer that enables native, trust-minimized cross-rollup transfers and unified liquidity under one EVM environment, rather than relying on external message-passing bridges. It inherits Ethereum security via validity proofs and features a disaster-recovery design that lets users recover assets from underlying chains even if the operator set halts. On Sepolia, batched proofs keep effective gas costs low and finality fast while giving developers a single network endpoint to reach users and assets across multiple L2s.

zkLink Nova Sepolia Testnet uses ETH as the gas token for transaction fees. You can obtain ETH by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
