wafermap@0.4.9
VERIFIED· install onlyPublisher claims: "Enables MCP clients such as Claude Desktop and Cursor to use an encrypted local x402 wallet for AI agents, with tools to check balance and resources, call paid resources, discover and pay third-party x402 services, quote and execute token swaps, and view history under per-payment and daily caps." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Nothing executable in the bundle ran; the trace covers the install step only.- Tested
- every file read, file written and host contacted by what ran
- Not tested
- use of the skill by an agent
What this means for the label: Verified here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.
Before you give it your token
- It will ask for
WAFERMAP_PASSWORDWAFERMAP_TOKENConfiguration, not credentials: SystemRoot, WAFERMAP_HOME, WAFERMAP_RPC_ARBITRUM, WAFERMAP_RPC_ARC, WAFERMAP_RPC_BASE, WAFERMAP_RPC_POLYGON, WAFERMAP_RPC_ROBINHOOD, WAFERMAP_RPC_SOLANA, WAFERMAP_RPC_SONEIUM, WAFERMAP_TIMEOUT_MS, WAFERMAP_URL- Where it talks to
- wafermap.xyz (its own)Also githubusercontent.com, x402.org, blockscout.com, basescan.org, solscan.io, arbiscan.io, polygonscan.com, arc.io, solana.com, kyberswap.com, geckoterminal.com — not the publisher's domain; check what for before connecting.
- What the honeypot saw
- no credential files read · no network
- What we could not test
- use of the skill by an agent
Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names githubusercontent.com, x402.org, blockscout.com, basescan.org, solscan.io, arbiscan.io, polygonscan.com, arc.io, solana.com, kyberswap.com, geckoterminal.com as well as its own vendor. The guard injects WAFERMAP_PASSWORD, WAFERMAP_TOKEN only into requests to wafermap.xyz (and its subdomains) and refuses the rest.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-11 and scored it 84/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.

Tokens estimated at four characters each. Skills load their instruction text when triggered; the figure is what that costs.
