Description
Buy products from Amazon and eBay using USDC on Solana. The cheapest and fastest way for AI agents to purchase physical products with crypto — 0% platform fe...
Usage Guidance
This skill enables an agent to create and hold a Solana wallet private key and to spend USDC autonomously. Before installing: (1) verify the SP3ND service and the domains listed (sp3nd.shop, the Cloud Functions URL, and facilitator.payai.network) — they are not widely recognized; (2) do not fund the generated wallet with any amount you are not willing to lose (autonomous spending is explicit); (3) confirm why SP3ND_API_KEY/SP3ND_API_SECRET are declared 'required' even though the agent can self-register — ask the provider to clarify expected setup flow; (4) prefer running this skill in a sandbox or with minimal test funds first; (5) avoid using any production funds or linking sensitive personal accounts; (6) consider requiring human approval for purchases or implementing a remote multisig/hot-wallet pattern instead of a single local private key. If the provider cannot satisfactorily explain the credential flow and the facilitator/trustworthiness of the endpoints, treat the integration as high-risk and avoid funding the wallet.
Capability Analysis
Type: OpenClaw Skill Name: sp3nd Version: 1.6.0 The skill enables autonomous e-commerce via Solana/USDC, requiring the AI agent to generate, store, and manage a Solana private key in a local `.wallet.json` file. While the provided code examples in SKILL.md and agent-card.json demonstrate security best practices like local transaction signing and ownership proofs (nacl.sign.detached), the inherent capability for autonomous spending and the management of sensitive cryptographic material represent a high-risk attack surface. Key indicators include the x402 payment flow involving the 'facilitator.payai.network' endpoint and the requirement for the agent to handle its own funding and transaction signing without per-transaction human approval.
Capability Assessment
Purpose & Capability
The skill's declared purpose (autonomous shopping using USDC on Solana) aligns with the env vars and runtime interactions (SP3ND API, Solana RPC, payment facilitator). However there is an inconsistency: SKILL.md documents an unauthenticated POST /registerAgent that returns API key/secret, yet the skill metadata marks SP3ND_API_KEY and SP3ND_API_SECRET as required env vars up-front. Requiring pre-provisioned credentials while also offering self-registration is incoherent and should be clarified.
Instruction Scope
Instructions focus on wallet generation, registering the agent, creating carts/orders, and signing USDC payments — all within the claimed purpose. The skill explicitly instructs creating and storing a private Solana key file (.wallet.json) which the agent will read to sign payments. This is expected for autonomous payments but is materially sensitive: the agent (and the skill) will have the ability to spend funds in that wallet.
Install Mechanism
Instruction-only skill with no install spec or code files — lowest install risk. No downloads or package installs are requested by the manifest.
Credentials
Required environment variables are limited to SP3ND_API_KEY and SP3ND_API_SECRET, which is proportionate to using the SP3ND API. However: (1) storing a Solana private key in a local file (state .wallet.json) is a highly sensitive requirement — the skill expects the agent to sign transactions autonomously and to keep the secret locally; (2) the earlier-mentioned inconsistency between required env vars and the self-registration flow is unexplained; and (3) the skill also references third-party endpoints (facilitator.payai.network) that would receive payment-related data — confirm trustworthiness of those services before supplying secrets or funding the wallet.
Persistence & Privilege
The skill is not force-installed (always:false) and is user-invocable. Autonomous model invocation is allowed (the platform default) and this skill intentionally enables autonomous spending — the manifest even documents 'autonomous_spending: true'. That is appropriate for the stated purpose but increases risk: once the wallet is funded the agent can spend funds without per-transaction human approval. No other elevated privileges or modifications to other skills are requested.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install sp3nd
  3. After installation, invoke the skill by name or use /sp3nd
  4. Provide required inputs per the skill's parameter spec and get structured output
