dflow-proof-kyc

dflow-proof-kyc is a skill for Claude Code, Codex from x402agent/solana-clawd. It costs 183 tokens per session (2,157 once invoked), scanned A, original, MIT.

A guide for connecting Solana wallets to DFlow Proof, an identity check that uses Stripe Identity and links a verified person to wallet addresses. It covers identity checks for your own app and the required checks for buying Kalshi prediction contracts through DFlow.

In plain words
What is it for?
Use it when adding KYC, meaning “know your customer” identity checks, to a Solana app or when implementing DFlow’s Kalshi trading requirements.
Why use it?
It removes the need to design the wallet-verification flow and explains how to check whether a wallet has completed the required identity check.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dflow-proof-kyc scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

DFlow Proof

Proof is DFlow's identity-verification primitive for Solana wallets. Stripe Identity verifies the person once; Proof links that verified identity to one or more wallet addresses. Builders query a public endpoint to check status.

There are two reasons to integrate it:

  • Self-gating your own app — any product that needs identity-based KYC (jurisdiction-gated DeFi, regulated token sales, identity-attested access, etc.) can use Proof as a ready-made primitive.
  • Kalshi PM trading on DFlow — DFlow's Trading API requires Proof for Kalshi prediction-market buys. This skill is also where the matching error handling lives.

Prerequisites

  • DFlow docs MCP (https://pond.dflow.net/mcp) — install per the repo README. This skill is the recipe; the MCP is the reference. Look up the deep-link signing code, the full parameter list, and user-journey diagrams via search_d_flow / query_docs_filesystem_d_flow — don't guess.
  • dflow CLI (optional, only relevant for Kalshi-trading use) — install per the repo README.

Part I — Proof as a generic primitive (self-gating)

Use this path when you need KYC for your own app, independent of Kalshi.

Check verification status

GET https://proof.dflow.net/verify/{address}{ "verified": boolean }. Public, no auth. Use it to gate features, to decide whether to show a "Verify me" CTA, or to short-circuit a restricted action.

Redirect the user to verify (deep link)

If the wallet isn't verified, redirect the user to Proof's hosted flow. The deep link carries a signed ownership proof so Proof can link the wallet to the verified identity automatically:

  • URL: https://dflow.net/proof?wallet=<addr>&signature=<sig>&timestamp=<ms>&redirect_uri=<url>
  • Optional: email, projectId.
  • Signature: user signs the exact message Proof KYC verification: {timestamp} (Unix ms, 13 digits) with their wallet; base58-encode the bytes.
  • Full signing snippet and parameter table → docs MCP, or read directly: /build/proof/partner-integration.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
