Description
Spinner.Cash is an application-layer privacy protocol built natively on the Internet Computer blockchain, combining zero-knowledge proofs (zk-SNARK) with ICP's smart contract ("canister") architecture to deliver anonymous, private transactions. Users deposit tokens and mint private notes redeemable at any time; Spinner keeps no record of user accounts or addresses, and zk-SNARK proofs allow withdrawal requests to be validated against matching deposits without revealing any details of the original transaction. The project's roadmap includes a command-line beta, open-source release (GPL-licensed, with a verifiable "Launch Trail" deployment tool), a web frontend (spnr.app), private BTC transactions leveraging ICP's direct Bitcoin integration (avoiding cross-chain bridges), an SPNR token with a bonding-curve AMM, and eventual transition to decentralized governance via a "Spinner DAO." The project positions itself as an evolution of ideas pioneered by Zcash and Tornado Cash, but built as a single cross-chain-capable application rather than a separate layer-1 blockchain or per-chain contract deployment, targeting Internet Computer and Bitcoin users seeking transactional privacy.
