receipt → consent → KeeperHub → exact proof
Close the tab.Prove the settlement.
FINALTab turns a receipt into an exact split, a frozen ledger and a KeeperHub-executed USDC settlement—with an independently matched testnet receipt at the end.

V2 testnet settlement rail
KeeperHub deployed the exact-source-matched V2 contract, then a separate one-atomic-unit run proved its dual-signature USDC rail with exact event and balance checks.
- 02 / Agent surface
Nine authenticated production MCP tools
The authenticated production manifest covers allocation, netting, freezing, simulation, approval, submission, and exact settlement verification.
- 03 / Autonomy boundary
Agents orchestrate. People authorize value.
Every debtor supplies external-wallet signatures, and broadcast also requires a short-lived approval signed by a permitted human wallet.
- 04 / Integration
Built to plug into KeeperHub
OpenAPI, discovery metadata, workflow templates, MCP, and independent receipt proof make the rail reusable from other agent systems.
The settlement route
One clear path, with every gap labelled.
A trustworthy money product should distinguish what works now from what still needs productisation. This is the exact state of the current build.

Checking providerFINALTab is checking this deployment before it labels automated extraction available. Deterministic arithmetic remains the final gate.

Invite
Backend provisionedThe London Supabase schema is live with RLS and indexed relations. Production has proved signed-in tab creation, owner membership, participant persistence and reload; two-user invite acceptance remains a separate release gate.

Sign
Debtor walletsEach debtor signs a USDC authorization and a V2 full-plan consent in their own wallet. The plan accepts only signer-provided wallet artifacts.

Settle
Rail + value proof liveKeeperHub simulated and executed one exact atomic V2 transfer; independent receipt, event, and balance checks verified the Base Sepolia result.
Follow one exact ledger
Watch a dinner tab become a proof boundary.
Move through a reconciled receipt, the uncompressed debt graph, conservation-safe netting and the exact event checks required for a settlement verdict.

Two independent proof boundaries
Deployment provenance and value movement are separate proofs.
KeeperHub first deployed the exact-source-matched V2 contract. A different execution then moved exactly one atomic unit of test USDC and passed independent event, balance, settlement-ID, and ledger-hash checks.

Testnet value only. Deployment provenance is not presented as settlement proof.
Agent-native testnet rail
Nine production MCP tools. One explicit money boundary.
Allocate and net deterministically, freeze an exact V2 plan, collect signatures from every debtor wallet, simulate through KeeperHub, then require a short-lived human approval artifact before broadcasting.
