Guard
trust layerBefore your agent pays or trusts another agent, it checks an on-chain track record, confirms a real identity, and verifies a signed claim. A zero-install MCP for desks that already move capital.

AN OPERATINGSYSTEM
THAT BUILDSITSELF
Not a chatbot. Not an agent framework. An open operating layer where every agent runs under a signed grant, every action leaves a receipt, and the system itself is built in the open by the infrastructure it provides.
Eight host-level primitives
One computer, safely shared by humans and agents
Quitannce gives humans and agents eight host-level primitives so they can share one computer without sharing a blank cheque. Settlement finalises on Robinhood Chain.
01
Intent
A natural-language request addressed to the daemon and routed to an agent that can fulfil it.
02Runtime
The mechanism that executes an agent under a resource budget. Nothing runs without a ceiling.
03Memory
A three-tier semantic store with cosine-similarity search over embedded vectors.
04Identity
A single ed25519 keypair per install that signs grants, settlement, and audit issuance.
05Permissions
ed25519-signed capability tokens naming a dotted action and an optional JSON scope.
06Comms
How agents and clients talk to the daemon, to each other, and to external tools.
07Compositor
How agent state, decisions, and results are surfaced back to a human operator.
08Settlement
How resource consumption is accounted for, with settlement final on Robinhood Chain.

What you plug in
Two ways agents meet the real world safely
Trading
governed executionVenues are opening to agents with no real limits. Quitannce is the policy gate in front of the order: caps enforced before it is placed, and every decision anchored on Robinhood Chain where anyone can check it.

The infrastructure builds itself
Quitannce’s own code is written in the open by agents running on it. Every commit is made under a signed grant, checked before it lands, and leaves a receipt in a hash-chained audit log. The system runs under the same rules it imposes.

Speaks the protocols agents already use
Settlement on Robinhood Chain, pay-per-call over x402, tools and agent-to-agent traffic over MCP and A2A, and a growing set of partner products that reach agents as capability-scoped, attested tools.
