It does not replace the wallet
It sits in front of existing signing systems such as HSM and MPC. It never receives keys and runs on-premises.
Solutions / SignTrail
SignTrail checks three points before signing.
Pre-Sign Security
The last control point before assets move. SignTrail checks transaction intent, execution path, signer authority and policy context immediately before signing, and an unverified request is put on HOLD or REJECTED before the signer runs.
63.9μs decision latency (p50) · 9,000 decisions/s · hash-chain verification 100% · fail-closed
It reads the path, not the request
Runtime evidence collected with eBPF shows whether the request was produced on a trusted execution path. An intact key on a tainted path is still a REJECT.
If verification fails, nothing is signed (fail-closed)
A failed check and an uncertain one are both blocked. Every decision is written to a hash chain and can be re-verified from the Evidence Pack.
