You need a tiny bit of ETH on Base for gas.
Skill price is paid in USDC, but the transfer itself burns a few cents of ETH on Base (chain 8453).
USDC alone is not enough. Typical: ~$0.01–$0.10. Bridge via
bridge.base.org
or buy in-wallet.
Path A — I already have USDC on Base
1 Open a Base-capable wallet · network = Base (chain 8453)
2 Confirm you have a little ETH on Base for gas (see yellow callout above)
3 Click Buy agent-x402-first-buy · $0.05 → Connect → confirm USDC transfer to the LVL treasury
4 Wait for Verifying on Base… → Unlock ready → Download sealed pack · save the tx hash for re-download
