Coldstar — Air-Gapped Signing for Agents

Client deliverableColdstar (own venture)2026live

Agent-safe signing on Solana with enforced spend limits; decks, master brief, and the Wintermute deck.

The work in one paragraph

Coldstar keeps the root key air-gapped and lets an agent sign inside a policy: per-transaction and daily limits, program and destination allow-lists, a signature audit log. The token went live on EasyA Kickstart's Solana venue and graduated to Meteora.
