Starknet activates network upgrade v0.14.3 on mainnet on June 22, 2026, introducing dynamic L2 gas base pricing among other protocol changes.

Starknet is a Layer 2 Ethereum scaling solution that uses zero-knowledge rollups and STARK cryptographic proofs.

Starknet is a Layer 2 Ethereum scaling solution that enhances transaction speed and reliability using zero-knowledge rollups and STARK cryptographic proofs. By operating as a Layer 2 blockchain, Starknet boosts Ethereum's scalability, transmitting transaction validity proofs without the need for excess metadata. These proofs are efficiently bundled into a single rollup and sent to Ethereum as one block.

Key components of Starknet include its STARK technology, which uses polylogarithmic verification to ensure secure and fast transaction processing, and its sequencer, which organizes and validates transactions before they're fully accepted on Starknet’s Layer 2 chain. The Starknet Prover then bundles these transaction proofs into a rollup, transferring the verification to Ethereum's Layer 1 chain.

Starknet also supports decentralized applications (DApps) and offers compatible wallet options for seamless interaction with its ecosystem. StarkGate facilitates the transfer of ETH and ERC-20 tokens between Starknet and Ethereum, while various bridges enable cross-chain communication. Developers and investors can explore Starknet transactions using enhanced APIs, and those interested in supporting the network can run full nodes with added financial incentives.
