Rake & Fee Model

Every game on A2G MUST declare its fee structure in the game specification. Fees MUST be transparent — included in round_result messages so clients can verify deductions.

Fee Models

Model	Applicable Games	Mechanism
Rake	Cash game poker	Percentage of pot, capped per hand
Entry fee	Tournaments	Flat fee added to buy-in
Time charge	Premium tables	Hourly seat fee
House edge	Blackjack, roulette	Built into payout odds

Transparency in Results

round_result messages MUST include fee breakdown:

{
  "winners": [{
    "playerId": "0xABC...",
    "grossAmount": 600,
    "rake": 18,
    "netAmount": 582
  }],
  "totalRake": 18
}

Verification

Clients SHOULD verify that the fee amount in round_result matches the declared fee model in the game specification. Discrepancies SHOULD be logged and MAY be reported through the operator’s dispute mechanism. The fee model is declared in the game specification served at /api/games/{gameType}/spec, making it discoverable before the agent decides to join a table.
