In your perimeter, next to your algo.
Your bot sends an unsigned payload. The vault decodes it, checks policy, and signs in microseconds, then the signed transaction executes at your venue.
- Keys never leave the enclave
- Policy checked before every signature
- Control plane stays off the hot path
Algorithmic by design.
Authenticate, open a wallet session, and sign the orders your bot builds. Keys stay in the enclave. The Rust SDK and REST API drive the same secured keys and policies as manual trading.
- Rust SDK and REST API
- Keys generated inside the enclave on first call
- Same keys and policies as FortkeyLink manual trading

}Payload-aware, compiled inline.
Policies and payload validations are compiled for your use cases ahead of time and run inline with the signing engine, in the same enclave.
- No external call to sign
- Full control over what you sign
- Sub-1ms end to end, benchmarked
Benchmarked end to end: decode, policy check, and signature at 372 µs p99, across 750,000 sustained EVM signs.
A remote signing call is required for every signature.
No external signing call. Keys remain isolated.
Under 1 ms is the end-to-end vault path (decode, policy check, and signature) on our EVM benchmark series in eu-west-1. Network time to your venue depends on colocation, and figures vary by chain.
Multi-region signing, MEV-protected routing.
Signing replicas in Ireland, Tokyo, and more on demand, latency-routed so bots sign next to the closest venue.
- Replicas placed next to block builders
- Private order-flow routing by default
- Cancel-on-disconnect: session drops trigger automatic cancels at the venue
A vault for every venue.
Pre-built HFT vaults for venues, strategies, and execution patterns. Each ships with a deployment guide and a default policy.
Hyperliquid
Co-located signing for Hyperliquid perps. Tuned for sub-block latency and order-book strategies.
Raydium
Solana AMM signing path. Optimized for swap routing and LP rebalancing inside one slot.
SolFi
Signing enclave for SolFi market making. Inline policy with venue-specific risk limits.
Uniswap
Uniswap v3 / v4 signing across mainnet and major L2s. Shared policy and audit envelope.
Aerodrome
Base-native AMM signing path. MEV-protected routing on by default.

A market maker cut signing latency by more than 90 percent
In a sandbox benchmark against its existing signer setup, a market-making desk measured a latency reduction of more than 90 percent on the signing path, with custody unchanged and every order checked against policy.
