mint-attest — Claude Code plugin

Attest completed work on MINT Protocol. After Claude finishes a substantive deliverable (code review, refactor, research, report, audit, tests…), it records a tamper-evident, on-chain proof of the work — what was done, when, and by whom — and returns a public Solscan verify URL.

Settled on Solana. Free to register, free to verify, $0.02 per attestation. Skips silently when MINT_API_KEY is unset, so it never blocks a task.

Install

claude plugin marketplace add FoundryNet/mint-attest-skill
claude plugin install mint-attest@foundrynet

(or add a local checkout: claude plugin marketplace add /path/to/mint-attest-skill)

Configure

export MINT_API_KEY=fnet_…        # free key at https://foundrynet.io
export MINT_AGENT_NAME="Claude Code"   # optional; the attesting agent's name

The skill installs the mint-attest PyPI SDK on first use; there is no Solana/wallet dependency on your side — the MINT server handles all on-chain interaction.

What gets recorded

Input/output are hashed locally (SHA-256) — your data never leaves, only the hash does. The record carries the work type, a summary, the duration, and the hashes, settled on Solana mainnet. Browse it at https://mint.foundrynet.io.
