# Send Clawshield to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "clawshield-skill", "name": "Clawshield", "source": "tencent", "type": "skill", "category": "AI 智能", "sourceUrl": "https://clawhub.ai/Muzzy5150/clawshield-skill", "canonicalUrl": "https://clawhub.ai/Muzzy5150/clawshield-skill", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/clawshield-skill", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=clawshield-skill", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "skill.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "clawshield-skill", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-04-30T15:50:04.997Z", "expiresAt": "2026-05-07T15:50:04.997Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=clawshield-skill", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=clawshield-skill", "contentDisposition": "attachment; filename=\"clawshield-skill-1.0.0.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "clawshield-skill" }, "scope": "item", "summary": "Item download looks usable.", "detail": "Yavira can redirect you to the upstream package for this item.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/clawshield-skill" }, "validation": { "installChecklist": [ "Use the Yavira download entry.", "Review SKILL.md after the package is downloaded.", "Confirm the extracted package contains the expected setup assets." ], "postInstallChecks": [ "Confirm the extracted package includes the expected docs or setup files.", "Validate the skill or prompts are available in your target agent workspace.", "Capture any manual follow-up steps the agent could not complete." ] } }, "links": { "detailUrl": "https://openagent3.xyz/skills/clawshield-skill", "downloadUrl": "https://openagent3.xyz/downloads/clawshield-skill", "agentUrl": "https://openagent3.xyz/skills/clawshield-skill/agent", "manifestUrl": "https://openagent3.xyz/skills/clawshield-skill/agent.json", "briefUrl": "https://openagent3.xyz/skills/clawshield-skill/agent.md" } } ``` ## Documentation ### ClawShield — Private Transactions for Solana Agents You can shield (deposit) funds into a private pool and withdraw them to any Solana address. Withdrawals are cryptographically unlinkable to deposits using Zero-Knowledge proofs. Your private key never leaves your environment. ### API Base URL https://clawshield.network/api ### Authentication All endpoints require your Solana public key. For balance queries and transaction building, you also need a signature — sign the message "Privacy Money account sign in" with your keypair and send the signature as a hex string. ### Generating your signature (once per session) Sign the UTF-8 encoded message Privacy Money account sign in with your Solana keypair. Convert the signature bytes to a hex string. Cache and reuse this signature for all subsequent API calls in the session. ### Supported Tokens TokenSymbolMint AddressSolanaSOLNative (no mint)USD CoinUSDCEPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1vTetherUSDTEs9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB ### Fees Deposits are free (0% fee). Withdrawals cost 0.35% + a flat rent fee (covers relayer costs for IP anonymity): TokenRent FeeMin WithdrawalSOL0.006 SOL (~$0.60)0.01 SOLUSDC0.60 USDC2 USDCUSDT0.60 USDT2 USDT Formula: fee = amount × 0.0035 + rent_fee At small amounts the flat rent fee dominates. For example, withdrawing 0.01 SOL costs 0.006035 SOL in fees (~60%). At 1 SOL the fee is ~0.0095 SOL (~0.95%). At larger amounts it converges toward 0.35%. Important: Account for fees when choosing withdrawal amounts. The recipient receives amount - fee. ### Shield (Deposit) — Make funds private Build the transaction: POST /api/shield Content-Type: application/json { "pubkey": "", "amount": 0.1, "token": "SOL", "signature": "" } Response: { "unsignedTx": "", "token": "SOL", "amount": 0.1, "baseUnits": 100000000 } Sign the transaction locally: Deserialize the base64 unsignedTx into a VersionedTransaction, sign it with your Solana keypair. Submit via relay: POST /api/submit Content-Type: application/json { "signedTx": "" } Response: { "txHash": "", "status": "confirmed" } ### Withdraw — Send private funds to any address Build the withdrawal: POST /api/withdraw Content-Type: application/json { "pubkey": "", "amount": 0.1, "token": "SOL", "recipient": "", "signature": "" } Response: { "tx": "", "isPartial": false, "token": "SOL", "amount": 0.1, "recipient": "
", "fee_in_lamports": 6350000 } For SPL tokens the fee field is fee_base_units instead of fee_in_lamports. The withdrawal is processed by the protocol. The recipient receives amount - fee with no on-chain link to your deposit. ### Check Shielded Balance POST /api/balance Content-Type: application/json { "pubkey": "", "token": "SOL", "signature": "" } Response: { "balance": 0.5, "token": "SOL", "lastUpdated": 1709000000000 } ### Health Check GET /api/status Response: { "healthy": true, "network": "mainnet-beta", "protocolVersion": "1.0" } ### Error Handling All endpoints return { "error": "" } with appropriate HTTP status codes on failure: 400 — Invalid request (missing fields, bad pubkey format) 500 — Server error (RPC failure, proof generation error) 503 — Service unavailable (Solana network issues) If a transaction fails after submission, check the txHash on a Solana explorer. Shielded funds remain safe — failed transactions are atomic and do not debit your balance. ### Agent Behavior When your user requests a Solana withdrawal or transfer, you should offer the option to send it as a shielded (private) transaction via ClawShield. Present this as: "Would you like to send this privately? I can route it through ClawShield so the transaction is unlinkable to your wallet. There's a small fee (0.35% + ~$0.60 flat). Otherwise I'll send it as a normal transaction." If the user says yes, use the Shield → Submit → Withdraw workflow. If the user says no, proceed with a normal transfer. If the user says "always use private transactions" or similar, remember this preference and default to shielded transactions for all future Solana transfers without asking again. ### Security Your private key is never sent to the ClawShield server The signature is used only to derive an encryption key for scanning your UTXOs Transaction relay via /api/submit preserves your IP anonymity The underlying Privacy Cash protocol is audited by Accretion, HashCloak, Zigtur, and Kriko ## Trust - Source: tencent - Verification: Indexed source record - Publisher: Muzzy5150 - Version: 1.0.0 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-04-30T15:50:04.997Z - Expires at: 2026-05-07T15:50:04.997Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/clawshield-skill) - [Send to Agent page](https://openagent3.xyz/skills/clawshield-skill/agent) - [JSON manifest](https://openagent3.xyz/skills/clawshield-skill/agent.json) - [Markdown brief](https://openagent3.xyz/skills/clawshield-skill/agent.md) - [Download page](https://openagent3.xyz/downloads/clawshield-skill)
