strkBTC is a wrapped Bitcoin asset on Starknet (Ethereum L2) that gives BTC holders optional privacy for their DeFi activity. Issued deterministically upon verifiable Bitcoin deposits — no custodian, no discretion. Users choose between public mode (standard ERC-20 behavior) and shielded mode (hidden balances and transfers). Privacy is built into the protocol via StarkWare's ZK technology, not reliant on mixers or third-party apps. strkBTC is also eligible for Bitcoin staking on Starknet — earn yield while keeping balances shielded. Designed to attract institutional capital that avoids public blockchains due to exposed positions and strategies. Global watch parties in London, Lisbon, NYC, Seoul, and Bengaluru on launch day.



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.
