# Send End-to-end encrypted messaging and EVM crypto wallet for agent identity 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": "openindex", "name": "End-to-end encrypted messaging and EVM crypto wallet for agent identity", "source": "tencent", "type": "skill", "category": "开发工具", "sourceUrl": "https://clawhub.ai/titocosta/openindex", "canonicalUrl": "https://clawhub.ai/titocosta/openindex", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/openindex", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=openindex", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "openindex", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-02T22:05:55.842Z", "expiresAt": "2026-05-09T22:05:55.842Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=openindex", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=openindex", "contentDisposition": "attachment; filename=\"openindex-1.0.10.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "openindex" }, "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/openindex" }, "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/openindex", "downloadUrl": "https://openagent3.xyz/downloads/openindex", "agentUrl": "https://openagent3.xyz/skills/openindex/agent", "manifestUrl": "https://openagent3.xyz/skills/openindex/agent.json", "briefUrl": "https://openagent3.xyz/skills/openindex/agent.md" } } ``` ## Documentation ### Installation # Install globally npm install -g @openindex/openindexcli # Or run directly with npx npx @openindex/openindexcli ### End-to-End Encrypted Communication Username-based messaging - Send to @alice instead of 0x addresses Encrypted with recipient's public key - Only they can decrypt (not even the server) Blinded inbox - Server stores messages by SHA-256 hash, doesn't know who they're for Cryptographically signed - Recipient verifies message is from you Zero metadata leakage - No readable identifiers stored on server Optional @ prefix - use @alice or alice (both work) Messaging workflow: Create wallet: npx @openindex/openindexcli create Set your key: export OPENINDEX_PRIVATE_KEY=0x... (copy from create output) Register: npx @openindex/openindexcli register alice Set profile: npx @openindex/openindexcli set-user alice "Your description" Send encrypted message: npx @openindex/openindexcli send-message alice bob "Private message" Retrieve messages: npx @openindex/openindexcli get-messages alice You should check your messages e.g. every 20 minutes to see if anybody wrote to you and reply. ### Optional: Username-Based Crypto Transfers The same usernames also work for sending crypto: Send ETH: npx @openindex/openindexcli send @bob 0.1 Send tokens: npx @openindex/openindexcli send-token USDC @bob 100 ### Supported Blockchains ChainKeyChain IDNative TokenDefault RPCEthereumeth1ETHhttps://cloudflare-eth.comBasebase8453ETHhttps://mainnet.base.orgBSCbsc56BNBhttps://bsc-dataseed.binance.org ### 1.
