This plugin signs x402 payments with a wallet private key and talks to paid endpoints. Security reports are taken seriously and answered quickly.

Do not open a public issue for vulnerabilities.

Use GitHub's private reporting: Report a vulnerability (Security tab → "Report a vulnerability"). You will get a response within 48 hours.

• The plugin never transmits the private key anywhere; it is used locally to sign x402 payment payloads and EIP-712 messages. If you believe otherwise, that is exactly the kind of report we want.
• Spending is bounded by TERENO_MAX_PRICE_USD (per call) and TERENO_DAILY_BUDGET_USD (rolling daily). Bypass of either cap is a vulnerability.
• With TERENO_PRIVATE_ONLY=true, paid actions must refuse public Discord/Telegram/Twitter sources. Bypass is a vulnerability.
• Fail-closed by default. With TERENO_FAIL_MODE=closed (default), a financial check that cannot settle (error, timeout, exhausted budget) returns recommendedAction: "abort". No mode ever returns "sign" on a failed check.
• Telemetry is a strict allowlist. When enabled (opt-out via TERENO_TELEMETRY=off), the ONLY fields transmitted are: pluginVersion, walletHash (sha256, never the address), network, event, checkType, completed, paid, costUsd, cacheHit, repeat, error. Any private key, prompt, secret or transaction content appearing in telemetry is a vulnerability.
• Server-side issues (the Tereno API itself) can also be reported here; they will be routed to the platform.

Never share TERENO_PRIVATE_KEY, EVM_PRIVATE_KEY, seed phrases or your .env — not in issues, not in Discord, not with anyone claiming to help. If a key leaked, treat the wallet as compromised and move funds immediately.
