Quitannce · open agent-native operating layer

AN OPERATINGSYSTEM
THAT BUILDSITSELF
Open source · Apache-2.0Robinhood Chain · x402 · MCP · A2A · Alpha live

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.

Observed, not hoped

The host keeps its own instruments

Security plate

Sonar walks the grant surface. Each ping is a finding the host already decided.

What you plug in

Two ways agents meet the real world safely

Guard

trust layer

Before 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.

Trading

governed execution

Venues 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.

Built in the open

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.

Ecosystem

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.
