Technical Simulation: This visualization demonstrates the timing advantage of co-located signing infrastructure.
Signing fast is a liability. You need to sign late- wait for the market to reveal itself, then execute in the final microseconds.
Sign at T-0 (must account for ~35ms network latency)
Sign at T-50ms (MPC coordination overhead)
Strategy: JIT Signing @ T-399.95ms
Waiting to observe slot...
On Solana, a block (slot) lasts approximately 400ms.
Traditional Signers

Signing late allows you to see the future. By holding your signature until the end of the slot, you can observe order flow and price updates that earlier signers missed. This is the essence of MEV (Maximal Extractable Value) protection and capture.
[!NOTE] JIT Signing requires the signing keys to be physically co-located with the Validator or RPC node to eliminate network round-trip time (RTT). This is only safe if keys are in a Nitro Enclave.
