StreamLine

StreamLine turns paying someone into a continuous, milestone-gated financial flow on Sui. Instead of lump-sum invoices, a client locks USDC into a shared on-chain stream. Funds drip to the recipient as work progresses — with rules enforced by Move, not a middleman.

Move is the source of truth for locks, milestones, and drips.
Indexer caches state for fast reads and live updates.
Keeper permissionlessly settles drips and auto-approves silent clients.
App is the human product (zkLogin, Pro payroll, privacy UI).
@streamline/sdk is the headless path for machines — resolve a handle, create a stream, read status.

What you can do today

Create milestone streams that lock testnet USDC
Address people as alice@streamline (SuiNS subnames)
Read stream state over REST / WebSocket
Run agents with a keypair or Enoki-sponsored gas

Privacy modes (default private engagement, amounts-only, public), yield vaults, borrowing, and payroll are live in the protocol and app. Start with Privacy and Finance — SDK v1 stays on the clear-stream path.
