Deal architecture
How negotiations are structured
Two mechanisms keep deals clean, auditable, and hard to bypass.
The agent mediates. The club and player never talk directly.
Every transfer case splits communication into two real-time rooms so the verified agent stays in the middle and the representation mandate holds.
Club-Agent room: transfer fee and payment timeline
Agent-Player room: personal salary and bonuses
System-enforced block on direct club-to-player contact

No direct club-to-player communication
Deal sheets, not chat messages, drive the terms.
Salary, signing fees, bonuses, transfer fees, and release clauses flow through a state machine. Once accepted, the data populates the final contract directly.
Structured fields remove wage ambiguity
Counter-offers preserve full term history
Acceptance locks terms and auto-fills the contract
