OpenChat users can send messages to each other containing tokens such as ICP. Users can upgrade to Diamond membership to have access to extra or enhanced features.

OpenChat is a chat application running end-to-end on the Internet Computer blockchain.

CHAT tokenholders own and govern the protocol.

# OpenChat Fees Methodology

## 1. Overview

OpenChat fees represent the daily USD value of diamond membership payments made by users on the OpenChat social platform built on the Internet Computer Protocol. This metric captures revenue generated from premium subscription services where users pay in either CHAT tokens (OpenChat's native token) or ICP tokens (Internet Computer's native token) for enhanced features and diamond membership status. The calculation aggregates all diamond membership payments per day and converts them to USD using end-of-day price feeds.

## 2. Data sources

- **Internet Computer Protocol event logs**: Application-level events from the OpenChat platform containing user interactions and payment transactions
- **Diamond membership payment events**: Specific payment events triggered when users purchase or renew diamond memberships, containing JSON payloads with payment amounts, token types, and subscription details
- **End-of-day price feeds**: CoinGecko API price data for CHAT tokens (`openchat`) and ICP tokens (`internet-computer`) used for USD conversion
- **Token metadata**: Mapping information to convert token symbols to standardized identifiers for price lookups

## 3. Step-by-step calculation

### Component A: Event deduplication
- **Purpose**: Clean and deduplicate raw OpenChat application events to ensure accurate payment counting
- **Logic**: Raw events from the OpenChat platform are processed to remove duplicates using a combination of timestamp, user identifier, event name, source, and JSON payload content. Events are ranked using row numbering partitioned by these key fields, and only the first occurrence of each unique event combination is retained
- **Key fields**: `timestamp` for event timing, `name` for event type identification, `user` for the paying user, `source` for event origin, and `payload` containing payment details in JSON format

### Component B: Diamond membership payment extraction  
- **Purpose**: Identify and extract payment details from diamond membership purchase events
- **Logic**: Filter deduplicated events to include only those with event name equal to `diamond_membership_payment`. Extract payment information from the JSON payload including the payment amount (with decimal correction by dividing by 1e8), membership duration, payment method flags, and token type. Map token symbols to CoinGecko identifiers where CHAT tokens map to `openchat` and ICP tokens map to `internet-computer`
- **Key fields**: `amount` representing the payment value in native tokens, `duration` indicating membership period, `token` specifying the payment currency, and `coingecko_id` for price lookup

### Component C: USD conversion and daily aggregation
- **Purpose**: Convert native token payments to USD values and aggregate by day
- **Logic**: Apply USD conversion using end-of-day price feeds from CoinGecko for the corresponding token types. Truncate event timestamps to daily boundaries to create daily aggregation periods. Add metadata fields including chain identifier as `internetcomputer`, market sector as `social`, and business segment as `social`
- **Key fields**: `daily_timestamp` for daily aggregation, `chain` for blockchain identification, `fees` for USD-converted payment amounts, and `coingecko_id` for price lookup reference

### Final aggregation
- **Combining components**: Daily diamond membership payments are summed by date, with all payments converted to USD values using historical end-of-day exchange rates
- **Currency conversion**: Native CHAT and ICP token amounts are converted to USD using CoinGecko end-of-day price feeds matched by date and token identifier  
- **Time aggregation**: Events are aggregated to daily boundaries using timestamp truncation, with all payments within a calendar day summed together
- **Final calculation**: The metric represents the total USD value of all diamond membership payments per day, with missing dates filled with zero values to maintain continuous time series data
