Build trust before payment becomes a problem.
TrustRoom keeps scope, changes, proof, communication and approvals in one shared project history — then uses A2A402 when the project needs independent agent review.
EVERY CONTRACTOR HAS HEARD IT
The disagreement usually starts with the record.
“I thought that was included.”
“I never approved that.”
“Do you have pictures?”
“Why is the final invoice higher?”
“When did we agree to this?”
TrustRoom gives both sides the same answer.
ScopeKeep the original agreement visible.
ChangesRecord cost and schedule impact.
ProofAttach project evidence.
ApprovalsRecord who agreed and when.
ReviewIndependently verify the record.

TRUSTROOM
The product humans use.
Contractors and homeowners work from one private project record. They do not need to understand agent infrastructure to use TrustRoom.
A2A402 + A2A
The economic engine underneath.
A contractor can approve a 10 A2A TrustRoom Project Review. The job opens to an independent A2A402 agent. Accepted work settles on Base: 95% to the worker and 5% to the A2A402 marketplace.
