# MIST

> Send anything to anyone privately with full compliance

MIST is a compliant privacy protocol on Starknet enabling private token transfers between wallets without revealing sender-recipient links.

MIST (FOCBB) is a privacy protocol built on Starknet that enables private token transfers using zero-knowledge proofs and pooled deposits. The Chamber product breaks the on-chain link between sender and recipient — senders deposit tokens with a claiming key, and recipients claim funds on any supported chain via ZK proof. FOCBB (Fully On-Chain Better Banks) is the underlying protocol for deploying compliant privacy ledgers configurable for any jurisdiction.

## Products

- [MIST Chamber](https://thegrid.id/profiles/mist): MIST Chamber is a privacy pool protocol on Starknet that breaks the on-chain link between sender and recipient using zero-knowledge proofs and pooled deposits. Senders deposit tokens with a claiming key; recipients produce a ZK proof of ownership to claim funds on any supported chain via cross-chain adapters. Supports ETH, USDC, USDT, and DAI with configurable compliance for jurisdiction-specific requirements. (Privacy Pool, In Development, Main Product)
- [MIST Hidemi](https://thegrid.id/profiles/mist): MIST Hidemi is a consumer application for private USDC transfers across multiple blockchain networks. Users generate a shareable payment link to receive USDC; senders pay from any supported chain without seeing the recipient's wallet address or history. Withdrawals use Groth16 zero-knowledge proofs to prevent deposit-withdrawal linkability. All transactions go through on-chain smart contracts with no custodial control by MIST. Authentication uses WebAuthn passkeys with device biometrics, requiring no seed phrases or account registration. Built on the Privacy Pools compliance model, users prove transaction innocence without revealing identity. Supports Ethereum, Base, Arbitrum, Optimism, Polygon, and StarkNet. (Privacy Pool, Live)
- [MISTzap](https://thegrid.id/profiles/mist): MISTzap is a QR code-based private payment application on Starknet. Users scan or share QR codes to send and receive multiple token types without exposing wallet addresses or transaction history. Payments are gasless and processed through the MIST zero-knowledge proof protocol, keeping sender and recipient wallets unlinkable. Built as a Next.js web application using the Starkzap SDK for Starknet account abstraction. (Privacy Pool, Live)
