安全使用建议
This skill appears to be legitimate Gateway integration documentation and examples, but it has an important transparency gap: the code samples rely on sensitive credentials (e.g., CIRCLE_API_KEY, CIRCLE_ENTITY_SECRET, DEPOSITOR_ADDRESS, and developer wallet private keys) even though the skill metadata declares no required environment variables. Before installing or running this skill:
- Treat the Circle API key and entity secret as highly sensitive. Only supply them in a secure server environment (not in browser clients) and never paste them into chat prompts.
- If you plan to use the developer-controlled wallet examples, provision and store credentials in a secrets manager and restrict their scope and network access.
- Ask the skill author (or registry) to update the metadata to declare required env vars and a homepage/source so you can verify provenance. The source is listed as "unknown" — prefer skills with a verifiable publisher.
- Review any runtime prompts carefully: the skill could ask you to paste keys or private-signing material; decline to provide private keys in an interactive chat.
- Consider only using the browser-wallet examples (which rely on user wallets signing locally) for client flows, and keep server-side credential flows isolated in your backend.
If you cannot confirm the author/publisher or do not want to manage Circle credentials, do not install or run server-side flows from this skill.
功能分析
Type: OpenClaw Skill
Name: use-gateway
Version: 0.1.0
The skill bundle provides a legitimate integration for Circle Gateway cross-chain USDC transfers across multiple EVM chains and Solana. It contains comprehensive reference implementations for deposits, balance queries, and cross-chain transfers using both browser wallets (wagmi/Anchor) and Circle's developer-controlled wallets SDK. The instructions in SKILL.md include strong security guardrails, such as mandatory user confirmation for transactions and strict rules against hardcoding secrets. All network interactions are directed to official Circle API endpoints (gateway-api.circle.com), and no evidence of malicious intent, data exfiltration, or prompt injection was found.
能力评估
Purpose & Capability
The skill claims to integrate Circle Gateway (expected). However, several reference files (e.g., references/deposit-evm-circle-wallet.md, references/deposit-evm-circle-wallet.md) include server-side flows that require Circle API credentials (CIRCLE_API_KEY, CIRCLE_ENTITY_SECRET) and a depositor address. The skill metadata declares no required environment variables or primary credential, which is inconsistent with the provided examples and server-side patterns.
Instruction Scope
SKILL.md and the reference files properly describe on-chain flows, signing, and calls to Circle Gateway API endpoints (gateway-api.circle.com). They do not appear to instruct arbitrary file reads or unrelated system access. However, the runtime instructions and examples assume the agent or developer will provide secrets (API keys, entity secrets, potentially private keys) and may run server-side flows — this scope (handling secrets and server ops) is not surfaced in the skill metadata and could lead to accidental secret exposure.
Install Mechanism
Instruction-only skill with no install spec and no code files that are executed by the platform. This is low-risk from an installer perspective (nothing downloaded or installed by the registry).
Credentials
Several example files explicitly reference environment variables and sensitive values (CIRCLE_API_KEY, CIRCLE_ENTITY_SECRET, DEPOSITOR_ADDRESS, and private keys implied by developer-controlled wallets), but the skill's declared requirements list no required env vars or primary credential. Requesting or using those secrets is proportionate to some server-side flows, but the omission from metadata reduces transparency and increases the chance of accidental secret disclosure.
Persistence & Privilege
The skill is not always-enabled (always: false) and model invocation is allowed (default). It does not request elevated platform persistence or modify other skills/configs in the provided materials.
