Actions do not fire until live miners agree.
Autonomous pre-action risk gate for Web3 & AI agents. Signalgate intercepts wallet actions, dispatches parallel intelligence asks to live Telegraph miners, settles payments via x402, and returns cryptographically proven verdicts before keys sign.

How Signalgate Protects Every Action
Never sign blind. Three decoupled stages ensure zero transactions execute without paid miner consensus.
Propose Action
A user or autonomous agent prepares an on-chain interaction: a large token transfer, contract approval, cross-chain bridge, or contract call. Instead of broadcasting directly to an RPC, it routes to Signalgate.
Decentralized Consensus
Signalgate queries live Telegraph miners in parallel. Miners analyze bytecode vulnerabilities, fraud registries, drainer signatures, and solvency. Each ask is settled via x402 USDC micropayments.
Enforced Verdict & Proof
The fail-closed policy engine computes consensus. If clean, it emits ALLOW with receipts. If danger is found, it immediately emits BLOCK. If payment or miners fail, it defaults to WAIT.
Enterprise Hardening
Built for High-Stakes Agent Autonomy
Engineered with enterprise rigor: dynamic miner discovery, decentralized consensus, and zero custody.
Zero Key Custody
Signalgate never requests or stores signing keys. It operates strictly as an advisory gatekeeper.
Strict Fail-Closed Policy
If the network is unreachable, catalog lacks required intents, or payment fails, execution stops at WAIT.
EIP-3009 x402 Micropayments
Automatic cryptographic settlement with Base Sepolia USDC. Every gate run produces economic miner demand.
24/7 Watchlist Poller
Background worker constantly monitors your multisigs, hot wallets, and vault contracts on interval.
Append-Only Audit Ledger
Every decision stores raw miner payloads, payment hashes, and latency metrics in a local SQLite ledger.
Explorer Hash Grounding
Direct links to Telegraph block explorer for every queried miner, eliminating hallucinated verdicts.
