Hardware-isolated key custody with cryptographic attestation.
Your keys never leave the enclave.
Enterprise-grade key management with hardware-level security guarantees.
ECDSA signing in 62 microseconds P99. No network hops, no cold starts.
Cryptographically verifiable proof that your code runs in an isolated enclave.
Instant key destruction with physical attestation. No software override possible.
Transaction limits, allowlists, and rate controls enforced at the hardware level.
Speed isn't about signing fast. It's about waiting longer than everyone else.
Round-trip to AWS KMS takes 130ms. In Solana, that's nearly 33% of a slot.
Because you sign early, you miss the auction data streaming in during the slot.
If your bundle lands too late because of network jitter, it reverts.
Deploy Sentinel Core directly inside your validator's VPC. Eliminate the internet. Sign over localhost.
Zero-copy packet injection directly to the NIC.
Construct and sign bundles in the same microsecond.
We bypass the standard Linux networking stack using XDP (Express Data Path). No context switches. No TCP overhead. Raw packet injection.
Sentinel Core speaks native Jito bundle format. Build atomic bundles or back-run competitors with microsecond precision.
Stop keeping your vote keys on disk. Sentinel Validator Edition runs inside a dedicated Nitro Enclave, automating vote signing while enforcing anti-slashing rules at the hardware level.
AWS KMS broadcasts your intent 130ms before you sign. Sentinel keeps you dark.
Signing via API creates network patterns that sophisticated bots track.
Your strategy engine is in Tokyo. Your KMS is in us-east-1. That 130ms is the window where you get front-run.
Because you broadcast to the public pool, MEV bots can sandwich your large orders.
Sentinel Core creates a direct, encrypted tunnel from your enclave to the block builder. Your transaction is never seen by the public mempool until it is already mined.
See exactly how much you lose to slippage and latency tax every year.
Quantify how much signing latency costs your firm annually in missed alpha and jitter losses.
ZeroCopy jitter tax modelGive your AI agents the ability to sign transactions without exposing private keys.
AI agents need to sign transactions, but giving them raw private keys is a security nightmare. Sentinel provides a secure signing API that lets agents operate autonomously within policy constraints.
