Prices are per stream (one audited environment, such as production in one region). Anchoring gas is paid by your own anchorer wallet: about 187,000 gas per anchor on Monad, a fraction of a cent.
Purchase and activate on chain.
USDC goes directly from your wallet to the Farnsworth treasury. The licence contract never holds funds, and paid time can never be revoked or shortened.
- Create your stream
Your owner wallet (we recommend a Safe) creates the audit stream on the ledger. See Get started. - Choose a plan
Only the stream owner can choose or change the plan. Anyone can add time to the current plan. - Approve and subscribe
Two transactions from a browser wallet, or one batched transaction from your Safe. - Optional: auto-renew
Authorise a number of renewals at a capped price. Your own gateway renews in the last three days of each period.

Questions
What happens if a subscription lapses?
There is a 7-day grace period. After it, the ledger stops accepting new anchors for that stream and the gateway stops serving AI traffic (it fails closed). Everything already anchored stays verifiable forever, and renewing resumes the same record chain. Records written in the meantime are signed and stored locally and are anchored with the next batch.
Can Farnsworth cancel or change my plan?
No. Paid time cannot be revoked or shortened, plan terms are immutable, and there is no upgrade path or pause in the contract. We can change the price of future purchases only, and every purchase carries a maximum price so a change cannot be pushed onto a pending transaction.
Can I switch plans?
Yes. The stream owner can switch at any time. The value of the time you already paid for is converted into time on the new plan at its current price.
Which tokens do you accept?
USDC on Monad today. Other dollar stablecoins may be added. Invoiced customers can pay by bank transfer.
