Brisk

Brisk is a stablecoin payment application built on Sui that makes transfers zero-gas at the protocol level: Sui's object model lets fees be abstracted to the application layer, so a user paying USDC needs no native token on hand. Accounts are created with zkLogin and passkeys, a social login produces a wallet, signing is done with the device's biometrics, and Enoki handles account abstraction and sponsored transactions.

A payment runs in two steps: send_funds moves the money and record_payment writes an order receipt, with both calls executed inside one transaction so the merchant receives a receipt usable for reconciliation. Move modules are split into spending_vault, merchant_registry and payment_receipt, governing limits, merchant whitelisting and receipts respectively. The wallet can also pair with an AI agent, opening a sub-account with a per-transaction cap and a rolling daily cap that rejects anything above them. The product is distributed as a public beta on Sui testnet, with USDC as the settlement currency.
