Fees
A flat 10 basis points on admitted notional, taken inside the clearing transaction and printed on every result.
The protocol fee
NoFomo charges 10 basis points (0.10%) on the notional admitted into an execution. It is a constant in both contracts (FEE_BPS = 10 in BlockClearing and MandateVault), so it can't be raised on an existing deployment. It applies the same way to clusters and to mandate executions.
How it is taken
- Everything wallets joined with.
- Escrow × fill ratio. The fee base.
- 10 bps of admitted. Refunds pay nothing.
fee = totalIn × 10 / 10,000
venue buy = totalIn − fee
The fee is paid to the deployment's fee recipient inside the same transaction as the buy. Because it comes out of the pooled notional before the single buy, every participant pays it at the same rate, and it is already inside the reported uniformPriceEth. The amount is reported as feeEth on every cleared cluster and is emitted onchain in the Cleared and Executed events as feePaid.
A cluster that settles at zero (nothing admitted) pays no fee. Leaving before close, claiming and revoking a mandate cost only gas.
