When OpenCode loads the plugin, it modifies OpenCode-related configuration, creates a wallet if absent, and starts a detached local payment proxy. A later chat response confirming a 402 payment can cause BCH to be sent through paytaca-cli. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-02T08:01:44.819Z - **Finished:** 2026-08-02T08:02:49.943Z - **Download time:** 27230 ms - **Static scan time:** 272 ms - **AI review time:** 37621 ms - **Total time:** 65124 ms ## Security analysis ### Published attack-surface review - **Summary:** When OpenCode loads the plugin, it modifies OpenCode-related configuration, creates a wallet if absent, and starts a detached local payment proxy. A later chat response confirming a 402 payment can cause BCH to be sent through paytaca-cli. - **Trigger:** OpenCode plugin load; then a Paytaca backend 402 response and user-chat yes/tier selection. - **Impact:** Changes the agent environment and can initiate cryptocurrency payment from the created or existing wallet. - **Evidence paths:** package.json, scripts/sync-cache.js, dist/index.js, dist/wallet.js, dist/proxy.js, dist/bundled/wrapper.js, dist/bundled/proxy.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-02T08:02:49.943Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** OpenCode extension setup plus a local x402 BCH payment proxy. - **Rationale:** Source shows a real agent-extension and cryptocurrency-payment capability, including runtime configuration mutation and detached process setup. It is documented and package-aligned, with no confirmed covert exfiltration or install-time foreign control-surface mutation. - **Files touched:** ~/.opencode-paytaca/config.json, ~/.opencode-paytaca/proxy.js, ~/.opencode-paytaca/paytaca-pay-wrapper.mjs, ~/.opencode-paytaca/proxy.pid, ~/.opencode-paytaca/heartbeat, ~/.local/share/opencode/auth.json, ~/.config/opencode/skills/paytaca-wallet - **Network endpoints:** https://api.paytaca.ai, http://localhost:${port}/v1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** dist/index.js writes OpenCode auth.json and installs a global paytaca-wallet skill on plugin load., dist/wallet.js automatically invokes paytaca-cli wallet create when no wallet exists., dist/proxy.js writes executable proxy/wrapper files and launches a detached local process., dist/bundled/wrapper.js can send BCH after a pending-payment confirmation. - **Evidence against:** package.json has only prepare; scripts/sync-cache.js copies dist to an existing OpenCode cache., README.md describes the wallet, proxy, backend, and 402 payment workflow., Network traffic is limited to configured Paytaca backend and localhost proxy paths., Payment code requires a 402 flow and a yes/tier response before sendBch. ## Public findings ### 1.
