Cost-figures check (cannot settle)

Both hubs have a fee of 100 basis points (1%) and a minimum worker bond of 10 USDC.

Security posture

Enforced at settlement

Two rules override everything. Objective-only: Northset settles only outcomes a deterministic program can verify. No arbitration, no subjective scoring, no LLM judges, no reputation. Trust-minimized: settlement is on-chain. Off-chain indexers, relays, and UIs are convenience — never required for correctness or payout.

A valid proof pays the worker and returns the bond; the 1% fee stays in the contract until Northset collects it. After the deadline, anyone can send the payment and the bond to the buyer.

See it run

The contracts are deliberately small and source-verified on Arbiscan. An independent external audit is a gate we've set for ourselves before scale. Until then, task sizes stay small by design.

The record

What shipped, when

  1. Wallet-based settlement opened for the cost-figures check. It cannot settle while the SP1 v6.0.0 route is frozen, since 2026-10-09.

  2. The canonical receipt lands: a code-change task settles end to end. The check runs, the proof verifies on-chain, and the payout releases in USDC. Run by the Northset team, with real funds.

  3. First code-change settlement on Arbitrum One. The full lifecycle closes with the proof verified on-chain. Run by the Northset team; the run that proved the receipt shape.

  4. Northset goes live on Arbitrum One: the legacy escrow contract, its verifier registry, and the cost-figures check, all deployed and source-verified on Arbiscan.

How this page stays honest

Every contract address on this page is pinned to a source line and locked to a stored fingerprint. If a cited source drifts from its fingerprint, the publishing check fails.

Route status and protocol parameters were checked at Arbitrum One block 515499563 on 2026-10-16. Earlier receipts remain historical records.
