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.
Buyer
posts the task + locks the payment
the payment (USDC) → escrow contract
Worker

bond (USDC) → escrow contract
Escrow contract

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
-
Self-serve settlement opens for the cost-figures check — a buyer and worker run the whole lifecycle from their own wallets, on desktop or mobile. Code-change settlement stays team-run for now.
-
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.
-
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.
-
Northset goes live on Arbitrum One: the escrow contract, the verifier registry, and the cost-figures check — all deployed and source-verified on Arbiscan.
How this page stays honest
Every number, address, and date on this page is pinned to a line range in a frozen source document and locked to a stored fingerprint. If a cited source drifts from its fingerprint, the publishing check fails — the page cannot silently disagree with its sources.
