{% hint style="success" %}
**Clarification:** Crypto prices are estimated and calculated based on; (1) xDAI 0.003 GWei; (2) Sonic 10 GWei; (3) Fantom 41 GWei, and; (4) Oasis 100 GWei gas price. The "Send message" gas limit is based on the length of the message. The "Create Group" gas limit depends on the number of members in the group and the encryption variable. Table calculation is based on a two-member encrypted group. References to USD prices are made for approximate fiat value illustration purposes only.

### Fee Model

Parallel to the underlying L1/L2 transaction gas cost, the service fees (i.e. protocol fees) are also settled on the smart contract level and is applicable for every email or message transaction. Total user cost equals the sum of the L1/L2 transaction gas and the service fees. Both the gas and service fees converge and manifest as one end-user communication transaction fee.

> **(1)** L1/L2 transaction gas cost; \
> \&#xNAN;**(2)** The protocol fees equals the sum of base-fee and dApp-owner-fee (i.e. 4P project). \
> \&#xNAN;**(2.1)** The base-fee is set generally by the OCC Protocol deployer as a constant within \[Mails] and \[Chat] smart contracts and can be adjusted based on the specific dApp. The protocol-fee is defined with $ value approximation (e.g. 0 to \~0.0075$ POL... ≡). \
> \&#xNAN;**(2.2)** The dApp-owner-fee is set by the dApp owner (i.e. 4P) independently based on the dApp economic model. It is defined by the $ value approximation (e.g. \~0.0075$ POL... ≡ for the email and \~0.0025$ POL...≡ for the message).&#x20;
