Run a check
Describe the transaction your agent is about to sign - or paste a mined transaction hash to verify it instead. Shield queries live Telegraph miners and returns a go/no-go verdict with per-check evidence.
Verdict
How it works
Every check below is a paid query to a live Telegraph miner. Shield never fabricates data - each answer arrives from the network with its own cost, latency and, when the engine issues one, a signal hash you can verify independently.
Gas conditions
A live miner reports current fee conditions on the target chain, so the agent never signs into a fee spike.
Onchain facts
Canonical transaction facts read from real chain state - the same check that verifies a mined transaction hash.
Price context
A live market price anchors the dollar value of what is about to move, before it moves.
Protocol health
When a protocol is named, its reported TVL helps flag drained or suspicious targets.
Verdicts are advisory - the final signing decision stays with the agent. Responses carrying a signal hash can be checked against the Telegraph explorer.
