STRK20 is Starknet's native privacy layer for ERC-20 tokens, integrated directly at the token level via ZK proofs rather than external mixers or wrapped assets. Announced in March 2026 by StarkWare, the standard allows any token on Starknet to operate with confidential balances and private transfers by default, while preserving full composability with DeFi. Selective disclosure lets users share transaction records with auditors, regulators, or accountants when legally required. The first integration is with Ekubo DEX, enabling anonymous swaps and staking from day one. Follows the strkBTC privacy launch on May 12.

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.
