Verifiable tasks, settled in USDC

Build on OCH-1.1, the proof-gated escrow protocol deployed on Arbitrum One.

Arbitrum OneUSDC escrowEIP-712 bidsZK settlement

Northset connects a deterministic task specification, an off-chain signed bid, USDC escrow, and an on-chain verifier. The result is a settlement path that developers can inspect from source commitments through payout.

Available now

Capability	Live status
Create and settle objectively verifiable tasks	Deployed on Arbitrum One
Escrow rewards and bonds	Native USDC with 6-decimal integer amounts
Select off-chain EIP-712 bids	Supported by the deployed hub
Verify deterministic statistics	`STATS_V1` is the active registry route
Inspect state and receipts	Directly available from Arbitrum One RPC and logs

The deployed contracts and chain logs are the settlement authority. This site, SDKs, indexers, and relays help developers integrate; if a convenience surface differs from direct chain state, direct chain state wins.

Protocol at a glance

OPEN -> SELECTED -> ACTIVE -> COMPLETED
OPEN -> CANCELLED
SELECTED -> OPEN
ACTIVE -> TIMED_OUT

OCH-1.1 uses a two-step selection and activation flow. Selection records the winning bid and delivers the encrypted key. Activation is the delegatee’s explicit step that posts the bond and starts the compute window.
