[Rustchain] security: add XAPS pre-execution audit before on-chain actions #7923

Description

@SentVan23

Context
We targeted Scottcjn/Rustchain because the matched file integrations/telegram-tip-bot/bot.py shows agent-controlled value movement.

Your agent code in integrations/telegram-tip-bot/bot.py (and similar locations) performs direct Web3 value-moving operations (send_transaction, transact, contract calls, etc.) from within what appears to be an LLM/agent/tool/skill execution path.

Matched code fragment (from our scout)

- /deposit — Show your RTC wallet address
- /withdraw <address> <amount> — Withdraw to external RTC wallet
- /leaderboard — Top RTC holders in the server

This is exactly the class of risk that autonomous agents are starting to encounter at scale — prompt injection or goal misgeneralization can turn a research or trading agent into an unintended wallet drainer.

Why XAPS exists
XAPS is the economic security / pre-execution audit layer for agents (the "Visa network" for A2A value transfer). Before any high-stakes on-chain action, the agent obtains a cryptographically-style receipt from an independent dual-LLM + rules Tollbooth. The receipt becomes portable trust evidence for downstream systems.

It is deliberately not a walled garden. It is a low-latency tollbooth on the open road.

Recommended 2-line integration (zero-friction DX)

from xaps import XapsClient, XapsRejectedError

# ... inside your agent tool / skill / executor, right before building or signing the tx ...
receipt = XapsClient(base_url="https://api.xaps.network").audit(
    action="execute_smart_contract",      # or "transfer", "swap", "approve", etc.
    contract_address=TARGET_CONTRACT,
    amount=float(AMOUNT),
)
if receipt["audit"]["status"] != "APPROVED":
    raise XapsRejectedError(receipt["audit"].get("beta_attack", "REJECTED"), receipt=receipt)

# Now safe to proceed with the original transaction logic

The call is ~200-300ms in practice, costs a prepaid $0.01 only on APPROVED, and returns rich diagnostic information on rejection so your agent can adapt.

Additional modern integration (MCP toolbelt)
For OpenClaw, Hermes, Cursor, or any MCP-capable runtime, we also ship a tiny stdio MCP server (registry: io.github.APMC1/xaps) that exposes xaps_audit(...) as a first-class required tool. Many agent frameworks are converging on MCP for tool use — adding the XAPS MCP server gives you the guardrail with almost no custom code.

Subsidized Sink Oracle (optional utility hook)
Agents that adopt XAPS also get access to a receipt-gated data oracle for fresh structured web data:

pip install xaps-sdk
xaps-mcp   # stdio MCP server — registry: io.github.APMC1/xaps
curl -s http://localhost:8766/oracle/health

Query via POST http://localhost:8766/oracle/query with an XAPS-Receipt header from XapsClient().audit(...).
Early adopters get subsidized query pricing while the network bootstraps.

Why this PR/Issue is high-signal for you

  • Detected risk signals:

  • Direct OpenClaw/Hermes/NemoClaw hit (+ecosystem priority)

  • Stars in sweet spot for welcome PRs (469)

  • Active in last 6 months

  • Moderate wallet/agent coupling

  • We deliberately only contact repos that show both real agent-controlled money movement and the exact pain points you have already described in issues or code. We are not spraying the ecosystem.

Next steps (low effort — live on https://api.xaps.network)

  1. Drop the 2-line guard in the hot path(s) (use base_url="https://api.xaps.network").
  2. Autonomous onboarding: POST /agents/register with your agent wallet → xaps_ key + up to $1 trial (wallet-linked, fast audits only). No human signup.
  3. When balance is low: GET /agents/funding-options — USDC (Base), TAO (Finney), or Stripe ($5+ recommended). Trial + crypto rails unchanged.
  4. Discovery + MCP install: https://api.xaps.network/.well-known/xaps-agent-card.json
  5. (Optional) Add the XAPS MCP server as a required skill/tool so dynamically generated behaviors go through the gate.

60-second smoke test

curl -s -X POST https://api.xaps.network/agents/register   -H 'Content-Type: application/json'   -d '{"wallet_address":"YOUR_WALLET","chain":"bittensor"}'

Happy to iterate on the exact insertion point or help with a ready-to-apply diff if you prefer a PR instead of an Issue.

This is the pattern the agent economy is converging on for safe, composable A2A economics. The earlier high-quality projects adopt it, the faster the network effects kick in for everyone.
