GhostBroker

GhostBroker is an agent procurement and settlement layer for the Synthesis hackathon.

The product thesis is simple:

• agents need private reasoning
• users need constrained delegation instead of blind wallet access
• payments and receipts need to be onchain and legible

Current direction

The first version is intentionally narrow:

• one broker agent
• one task intake flow
• one provider-selection workflow
• one approval step
• one real settlement path
• one durable receipt trail

This shape is designed to fit the Synthesis meta-theme while remaining credible for multiple partner tracks, especially OpenServ, Base, MetaMask, Uniswap, Self, and ENS.
