M10 Blockchain Agent

Ask a question in plain English. Get a structured analysis backed by live blockchain data — no query language, no SDKs, no index knowledge required.

Base URL https://agent.onesource.io
Auth HTTP 402 (x402 protocol, no API keys)
Price $0.04 USDC per query
Networks Ethereum mainnet · Sepolia · Avalanche

Payment

This is a paid endpoint. Requests without payment receive HTTP 402 with a payment-required header describing the price, network, and recipient. Paid requests include a payment-signature header and are processed normally.

Payment uses the x402 protocol — an open standard for HTTP-native payments. The skill itself does not manage wallets or signing; it only returns standard HTTP 402 responses. Payment handling is the responsibility of the calling client or platform.


Privacy & Data Handling

  • Queries are sent to https://agent.onesource.io — an external service operated by OneSource. Your natural-language query text and any addresses you include are transmitted.
  • query_traces in the response contains an audit trail of internal data lookups. This may echo parts of your query. Omit it from user-facing output if not needed.
  • No data is stored beyond what is needed to process the request.

Capabilities

Indexed Historical Data

5.8 billion+ records across Ethereum mainnet, Sepolia testnet, and Avalanche C-Chain.

Events & Activity

  • "How many Transfer events happened in the last 24 hours?"
  • "What events did 0xdead... emit this week?"
  • "Top 10 contracts by event count over the last 30 days"
  • "Show me all Approval events for USDC in the last hour"

Transactions

  • "What's the average gas used per transaction on mainnet today?"
  • "How many transactions did 0xabc... send in the last 30 days?"
  • "Show the 5 highest-value transactions in block range 21000000–21001000"
  • "What's the transaction volume trend week over week for the last month?"

Blocks

  • "What was the average block time last week?"
  • "Which blocks had the highest gas utilization in the past 24 hours?"
  • "How many blocks were produced per hour yesterday?"

Token Transfers (ERC-20 / ERC-721 / ERC-1155)

  • "What ERC-20 tokens did 0xabc... receive in the last month?"
  • "Top 5 ERC-20 tokens by transfer volume this week"
  • "Show all mint events for USDC in the last 7 days"
  • "How many unique wallets received WETH in the last 24 hours?"

NFTs

  • "Show me BAYC token #4321 — name, image, and attributes"
  • "What were the last 5 CryptoPunks sales and their prices?"
  • "How many NFTs did 0xabc... receive this month?"
  • "Top 10 NFT collections by transfer count today"

Contracts

  • "When was Uniswap V3 deployed and who deployed it?"
  • "How many contracts were deployed on mainnet in the last 7 days?"
  • "Is 0xabc... a contract or an EOA?"

Live Chain State

Real-time lookups directly from Ethereum archive nodes — no indexing lag.

  • "What's the current ETH balance of 0xabc...?"
  • "What's the current gas price on mainnet?"
  • "Did transaction 0x123... succeed or revert?"
  • "What's the latest block number right now?"
  • "What's the USDC balance of 0xabc... at the current block?"
  • "How much ETH does Vitalik's address hold?"
  • "What's the current EIP-1559 base fee and priority fee?"

Smart Contract Analysis

Analyze any deployed contract's bytecode — including unverified contracts — to extract its interface without needing source code.

  • "What functions does 0xabc... expose?"
  • "Decompile 0xabc... and show me the function selectors"
  • "Compare the public functions of these two contracts: 0xabc... and 0xdef..."
  • "Does 0xabc... implement ERC-721?"

Pricing

Requests are priced per-query at $0.04 USDC via the x402 payment protocol (see Payment above).

Network Asset Scheme Endpoint
Base USDC exact https://agent.onesource.io

The usage.estimated_cost_usd field in every response shows exactly what each query cost.


Request

POST /
Content-Type: application/json

{
  "query":      "string — required. Your natural language question.",
  "session_id": "string — optional. Custom ULID. Auto-generated if omitted."
}

Response

{
  "session_id": "01JMQX7K3N...",
  "status":     "completed | error | processing",
  "summary":    "Plain text summary, 1–3 sentences. Present on success.",
  "response":   "Full Markdown analysis with tables, headers, code blocks.",
  "steps": [
    {
      "agent":       "router | opensearch | rpc | evmole",
      "action":      "Description of what was queried",
      "status":      "completed | failed"
    }
  ],
  "usage": {
    "total_tokens":       5820,
    "estimated_cost_usd": 0.0018
  },
  "query_traces": [...],
  "error": "string | null"
}

summary — plain text, 1–3 sentences. Display this prominently. response — full Markdown. Render it, don't parse it as structured data. query_traces — raw audit trail of every data query made internally.


Error Codes

Code Meaning Fix
402 Payment required Include payment-signature header
409 Session already exists Omit session_id or use a new one
422 Malformed request Check query field is present
500 Pipeline error Try rephrasing the query

What M10 Won't Answer

The agent rejects queries requiring unbounded full-index scans with no filter:

  • "List every transaction ever"
  • "Give me all NFTs"
  • "Show everything in the last year"

Add a filter (address, time range, event type, contract) and it works:

  • "List the last 10 transactions from 0xabc..."
  • "Top 10 NFT collections by mint count in the last 24 hours"
  • "How many transactions happened last year?" (aggregation — fine)
Usage Guidance
This skill is coherently described and appears to do exactly what it says: send your queries to OneSource's paid API and return structured analysis. Before installing, consider: (1) cost — each query is billed ($0.04 USDC per the doc) and your platform must support the x402 payment flow; (2) privacy — your query text and any blockchain addresses you include are transmitted to an external service and may appear in `query_traces`; avoid sending sensitive secrets or private data; (3) trust & retention — the skill claims no long-term storage but that is a statement from the external provider; review OneSource's privacy and terms if you need stronger guarantees. If you rely on on-prem or offline data, this skill is not appropriate. Otherwise the skill is internally consistent and does not request unnecessary permissions.
Capability Analysis
Type: OpenClaw Skill Name: m10-blockchain-agent Version: 1.0.4 The skill bundle is benign. It transparently describes its function: sending user-provided natural language queries to an external, paid API endpoint (https://agent.onesource.io) for blockchain data analysis. The `skill.md` clearly states that queries are sent to this external service and outlines the payment protocol (x402). There is no evidence of malicious intent, such as data exfiltration beyond the stated query, unauthorized execution, persistence mechanisms, or deceptive prompt injection instructions against the agent itself. All described behaviors are aligned with the stated purpose.
Capability Assessment
Purpose & Capability
The name/description (Ethereum blockchain query agent) matches the instructions: all queries are POSTed to https://agent.onesource.io, responses include structured fields, and the documented capabilities (events, txs, contracts, live state) align with the service description. No unrelated env vars, binaries, or install steps are requested.
Instruction Scope
The SKILL.md explicitly requires network access and transmitting the user's natural-language query (and any included addresses) to the external OneSource endpoint. It also documents that responses include a `query_traces` field which may echo query content and should be omitted from user-facing output if not needed. The instructions do not ask the agent to read local files or environment variables. Note: declarations such as 'No data is stored' are claims by the external service and cannot be independently verified from the skill text.
Install Mechanism
No install spec and no code files — instruction-only. This is the lowest-risk install profile because nothing is written to disk by the skill itself.
Credentials
The skill requests no environment variables, credentials, or config paths. The only external requirement is that the caller/platform implement the x402 payment flow (HTTP 402 / payment-signature headers). Payment handling is a client/platform responsibility; the skill does not request wallet keys or secrets.
Persistence & Privilege
always:false and user-invocable:true (defaults) — the skill does not request permanent or elevated presence. It does not instruct modification of other skills or system configuration.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install m10-blockchain-agent
  3. After installation, invoke the skill by name or use /m10-blockchain-agent
  4. Provide required inputs per the skill's parameter spec and get structured output
