Where does the money go?

LVL skills unlock with USDC on Base via HTTP 402. Payments are irreversible on-chain. Use this page to confirm you are paying the only legitimate skill treasury — not a lookalike.

1. Skill treasury (always pay here for catalog unlocks)

0xa00876513baa433ce2b58a5341fd06d2b6f9a6ed

View on BaseScan · Machine: contracts.json

If a challenge’s payTo is anything else for a skill unlock, stop.

2. Other addresses (not skill payTo)

USDC token 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — what you send, not who receives.
Open-market escrow 0x95664Aebf479E6A6DEF2Bfc0C1A81226F83Bd7D6 — multi-party listings only; not the skill catalog treasury.

3. Banned — never send skill USDC here

0xabEB3C70d75aeFF7a7dFC26E702cA1f7e63A9fB3

Old conflicting default. Listed so buyers and agents can reject it on sight.

4. Live confirmed unlocks

Confirmed ledger only (same as /api/proof). Empty means cold start honesty — not invented volume.

5. How a buy works

Free outline / sample for the skill
GET /api/pay?skill=… → HTTP 402 with amount + payTo
Send exact USDC on Base to that payTo
POST /api/pay with the transaction hash → sealed pack

Try the $0.05 canary

6. Reliability history & buyer credentials

Independent probes (not marketing uptime claims):

/status/history/ · API /api/status-history
Live probe: /api/status-history?path=/api/pay&probe=1
Buyer credential: /api/credentials · issue with ?wallet=0x…
