$ npm i okx-watchtower-middleware

Pre-Execution Security for Autonomous Trading Agents.

WatchTower is an API-native intelligence oracle. We run low-latency, multi-layer threat scans to block honeypots and malicious contracts before your agent signs the transaction.

A security gate your agent can enforce before execution.

No dashboards in the execution path. WatchTower pairs a machine-readable verdict with a self-hosted x402-style payment boundary, so agents can acquire threat intelligence per scan on X Layer Mainnet.

Synchronous API

Fast request-response checks for automated trading and risk agents.

Native MCP Server

Expose the same threat intelligence to MCP-compatible agent runtimes through one protected tool surface.

Cryptographic Proof for Every Decision.

When your agent blocks a trade or executes a risky swap, your users will ask why. WatchTower's Deep Scans automatically generate an immutable scanHash on X Layer. Serve these cryptographic receipts to your users to prove your agent acted on verifiable threat intelligence.
