# Send Basecred ERC-8004 Registration 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. Then review README.md for any prerequisites, environment setup, or post-install checks. 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. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "basecred-8004-registration", "name": "Basecred ERC-8004 Registration", "source": "tencent", "type": "skill", "category": "通讯协作", "sourceUrl": "https://clawhub.ai/Callmedas69/basecred-8004-registration", "canonicalUrl": "https://clawhub.ai/Callmedas69/basecred-8004-registration", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/basecred-8004-registration", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=basecred-8004-registration", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "README.md", "SKILL.md", "package-lock.json", "package.json", "references/chains.md", "references/sdk-reference.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-04-23T16:43:11.935Z", "expiresAt": "2026-04-30T16:43:11.935Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=4claw-imageboard", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=4claw-imageboard", "contentDisposition": "attachment; filename=\"4claw-imageboard-1.0.1.zip\"", "redirectLocation": null, "bodySnippet": null }, "scope": "source", "summary": "Source download looks usable.", "detail": "Yavira can redirect you to the upstream package for this source.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/basecred-8004-registration" }, "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/basecred-8004-registration", "downloadUrl": "https://openagent3.xyz/downloads/basecred-8004-registration", "agentUrl": "https://openagent3.xyz/skills/basecred-8004-registration/agent", "manifestUrl": "https://openagent3.xyz/skills/basecred-8004-registration/agent.json", "briefUrl": "https://openagent3.xyz/skills/basecred-8004-registration/agent.md" } } ``` ## Documentation ### Basecred ERC-8004 Registration Register AI agents on the ERC-8004 on-chain registry through a guided chat experience. ### Step 1: Auto-Prefill When the user triggers registration, auto-fill every field you can from: Agent identity files (IDENTITY.md, SOUL.md, USER.md) Environment (.env — wallet address derived from private key) Previous context (A2A endpoint, description, image, etc.) Sensible defaults (version: 1.0.0, license: MIT, chain: Base, storage: onchain) Do NOT ask questions one by one. Prefill first, ask later. ### Step 1.5: Explain Config Defaults Before showing the draft, briefly explain the config so users understand what's pre-selected and what alternatives exist: ⚙️ Config defaults (you can change these later): Chain: Base (8453) — where your agent lives on-chain Others: Ethereum, Polygon, BNB, Arbitrum, Celo, Gnosis, Scroll Storage: Fully onchain — agent data stored directly on-chain Alternative: IPFS — data pinned to IPFS, hash stored on-chain Trust: Reputation — other agents/users rate your agent on-chain Others: Crypto-Economic (staking/slashing guarantees) TEE Attestation (hardware-level trust proof) x402: Off — no payment protocol On: agent can charge for services via x402 payment protocol Active: On — agent is discoverable and accepting requests Off: registered but hidden from discovery Wallet: Your agent's on-chain identity address Two ways to set it: Option A: Paste your wallet address → Just paste your 0x... address → Agent will be linked to this address on-chain Option B: Add private key to .env (for signing) → Set PRIVATE_KEY=0x... in your .env file → Wallet auto-detected + can sign transactions → Enables setWallet() via EIP-712 after registration 💡 Option A is easier. Option B is needed if you want the agent to sign transactions on your behalf. Show this once at the start, not repeated on every draft. ### Step 2: Show Full Draft with Buttons (Single Message) Send the entire draft + buttons as one message using the message tool. This keeps buttons directly below the draft. Important: Use message action=send with both message (the draft text) and buttons (inline buttons). Do NOT split into reply + separate button message. After sending, reply with NO_REPLY to avoid duplicate. Use ✅ (filled) and ⚠️ (missing/needs attention): 📋 Agent Registration Draft ── Basic Info ── ✅ Name: Mr. Tee ✅ Description: AI agent with a CRT monitor... ✅ Image: pbs.twimg.com/... ✅ Version: 1.0.0 ✅ Author: 0xdas ✅ License: MIT ── Endpoints ── ✅ A2A: a2a.teeclaw.xyz/a2a ⚠️ MCP: (none) ── Skills & Domains ── ✅ Skills (5): natural_language_processing/natural_language_processing, natural_language_processing/natural_language_generation/summarization, natural_language_processing/information_retrieval_synthesis/question_answering, analytical_skills/coding_skills/coding_skills, images_computer_vision/images_computer_vision ✅ Domains (5): technology/blockchain/blockchain, technology/blockchain/defi, technology/technology, technology/software_engineering/software_engineering, technology/software_engineering/devops ✅ Custom: agent_orchestration/agent_coordination, social_media/content_management ── Config ── ✅ Chain: Base (8453) ✅ Storage: Fully onchain ✅ Active: true ✅ Trust: reputation ✅ x402: false ✅ Wallet: 0x1348...e41 (auto .env) Tap to edit a section or register: Buttons (attached to same message): Row 1: [✏️ Basic Info] [✏️ Endpoints] Row 2: [✏️ Skills & Domains] [✏️ Config] Row 3: [✅ Register] [❌ Cancel] ### Step 3: Section Editing (on button tap) Instant feedback: When any button is tapped, immediately acknowledge before doing anything else: ButtonInstant Feedback✏️ Basic Info"📝 Editing Basic Info..."✏️ Endpoints"🔗 Editing Endpoints..."✏️ Skills & Domains"🏷️ Editing Skills & Domains..."✏️ Config"⚙️ Editing Config..."✅ Register"⏳ Starting registration on Base..."❌ Cancel"❌ Registration cancelled."↩️ Back to Draft"📋 Back to draft..."

Repeat until user taps ✅ Register. ### Step 5: Execute Only after explicit ✅ Register confirmation. Write the registration JSON to a temp file Run the script: source /path/to/.env node scripts/register.mjs --json /tmp/registration.json --chain 8453 --yes The script handles: register() → setA2A()/setMCP() → addSkill()/addDomain() → setWallet() ### Step 5.5: Progress Updates Send progress updates during registration: ⏳ Step 1/3: Minting agent NFT on Base... ✅ Agent minted! ID: 8453:42 ⏳ Step 2/3: Setting endpoints & metadata... ✅ Endpoints configured ⏳ Step 3/3: Linking wallet via EIP-712... ✅ Wallet linked! ### Step 6: Report Result ✅ Agent Registered on Base! Agent ID: 8453:42 Wallet: 0x1348...e41 A2A: a2a.teeclaw.xyz/a2a TX: 0xabc...def View: https://8004.org/agent/8453:42 ### Missing Required Fields If Name or Description are empty after prefill, mark them ⚠️ and block registration. Show: "Please fill required fields first." ### No Wallet ⚠️ No wallet detected. You need one to register: Option A: Paste your 0x... address Option B: Add PRIVATE_KEY to your .env file ### Transaction Failures Show error clearly and offer retry: ❌ Registration failed: insufficient funds for gas [🔄 Retry] [❌ Cancel] ### setWallet Failure Public RPCs (e.g. mainnet.base.org) don't support eth_signTypedData_v4. If setWallet fails: ⚠️ Wallet linking failed (public RPC limitation). You can link your wallet manually at https://8004.org This is non-blocking — the agent is registered, just wallet isn't linked on-chain yet. ### Duplicate Registration Prevention The script checks if the wallet already owns agent(s) on the target chain before submitting. If detected: ⚠️ Warning: This wallet already owns 1 agent(s) on Base. Registering again will create a duplicate. Use update.mjs to modify an existing agent instead. In chat flow, warn the user and suggest updating instead of re-registering. The check is non-blocking if --yes is passed. ### Already Registered If the agent already has an agentId, offer to update instead of register. ### Registry Overrides The SDK only ships with Ethereum Mainnet registry addresses. For Base and other chains, the script passes registryOverrides with deterministic contract addresses: Identity Registry: 0x8004A169FB4a3325136EB29fA0ceB6D2e539a432 Reputation Registry: 0x8004BAa17C55a88189AE136b182e5fdA19dE9b63 ### Transaction Handling The SDK returns TransactionHandle objects. Use .waitMined() (not .wait()) to await confirmation. ### Basic Info FieldRequiredDefaultAuto-sourceAgent Name✅—IDENTITY.mdAgent Addressauto—.env private key or pastedDescription✅—IDENTITY.md / SOUL.mdImageNo—Profile image URLVersionNo1.0.0—AuthorNo—USER.mdLicenseNoMIT— ### Endpoints FieldRequiredDefaultAuto-sourceA2A EndpointNo—IDENTITY.mdMCP EndpointNo—— ### Skills & Domains FieldRequiredDefaultSelected SkillsNo[]Selected DomainsNo[]Custom SkillsNo[]Custom DomainsNo[] ### Advanced Config FieldRequiredDefaultTrust ModelsNo[] (suggest: reputation)x402 SupportNofalseStorageNohttp (fully onchain)ActiveNotrueChainNo8453 (Base) ### Supported Chains ChainIDDefaultBase8453✅Ethereum1Polygon137BNB Chain56Arbitrum42161Celo42220Gnosis100Scroll534352 All chains use the same deterministic contract addresses. ### JSON Template (8004.org format) { "basicInfo": { "agentName": "", "agentAddress": "", "description": "", "image": "", "version": "1.0.0", "author": "", "license": "MIT" }, "endpoints": { "mcpEndpoint": "", "a2aEndpoint": "" }, "skillsDomains": { "selectedSkills": [], "selectedDomains": [], "customSkills": [], "customDomains": [] }, "advancedConfig": { "supportedTrusts": [], "x402support": false, "storageMethod": "http", "active": true }, "version": "1.0.0" } ### Environment Variables VariableRequiredDescriptionPRIVATE_KEY / AGENT_PRIVATE_KEY / MAIN_WALLET_PRIVATE_KEYYesWallet private keyRPC_URLNoCustom RPC (auto-detected per chain)CHAIN_IDNoDefault chain (8453) ### Other Operations # Search agents node scripts/search.mjs --name "AgentName" --chain 8453 # Update agent node scripts/update.mjs --agent-id "8453:42" --name "NewName" --yes # Give feedback node scripts/feedback.mjs --agent-id "8453:42" --value 5 --tag1 "reliable" --yes ### Setup bash scripts/setup.sh ## Trust - Source: tencent - Verification: Indexed source record - Publisher: Callmedas69 - Version: 1.0.0 ## Source health - Status: healthy - Source download looks usable. - Yavira can redirect you to the upstream package for this source. - Health scope: source - Reason: direct_download_ok - Checked at: 2026-04-23T16:43:11.935Z - Expires at: 2026-04-30T16:43:11.935Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/basecred-8004-registration) - [Send to Agent page](https://openagent3.xyz/skills/basecred-8004-registration/agent) - [JSON manifest](https://openagent3.xyz/skills/basecred-8004-registration/agent.json) - [Markdown brief](https://openagent3.xyz/skills/basecred-8004-registration/agent.md) - [Download page](https://openagent3.xyz/downloads/basecred-8004-registration)
