# Calyx Trading volume Methodology

## 1. Overview

Calyx trading volume measures the total value of funds raised by launchpad projects on the Calyx platform. This metric captures capital inflows to launchpad contracts as investors participate in token sales. The calculation identifies all Calyx launchpad contracts, tracks fund transfers received by these contracts, and aggregates the daily volume in USD terms. This metric answers the business question of how much capital is being deployed through the Calyx launchpad infrastructure.

## 2. Data sources

- **NEAR blockchain receipts**: Transaction receipts containing function call data and execution status
- **Launchpad creation events**: Function calls to create new launchpad contracts on the Calyx factory
- **Token configuration events**: Function calls that configure launchpad token settings
- **Fund transfer events**: Token transfer function calls (`ft_on_transfer`) to launchpad contracts
- **Token metadata**: Information about token decimals and contract addresses
- **End-of-day price feeds**: USD pricing data for token value conversion

## 3. Step-by-step calculation

### Component A: Launchpad identification
- **Purpose**: Identifies all valid Calyx launchpad contract addresses
- **Logic**: Scans NEAR blockchain receipts for successful `finish_create_launchpad` function calls made to the `calyx-factory.near` contract. Extracts the `launchpad_account_id` from the function call arguments to identify each newly created launchpad contract. Filters for events after 2025-10-05 (Calyx contract creation date) and excludes failed transactions.
- **Key fields**: `launchpad_address` extracted from function call arguments, `block_timestamp` for temporal filtering

### Component B: Token mapping
- **Purpose**: Associates each launchpad with its sale token contract
- **Logic**: Identifies token configuration by finding `new` method calls to launchpad contracts. Parses the function call arguments to extract the `sale_token_account_id` from the configuration data. Joins with the launchpad identification data to ensure only valid launchpads are processed.
- **Key fields**: `sale_token_address` from configuration arguments, `launchpad_address` for joining

### Component C: Fund transfer capture
- **Purpose**: Captures all capital raised by launchpad contracts
- **Logic**: Identifies fund transfers to launchpad contracts by finding `ft_on_transfer` function calls where the receiver is a valid launchpad address. Extracts the transfer `amount` from function call arguments and casts to high-precision numeric format. Applies key exclusion logic to prevent counting circular transfers where the token being transferred is the launchpad's own sale token. Filters for successful transactions after the Calyx launch date.
- **Key fields**: `amount` from transfer arguments, `token_address` (sender), `receiver_id` (launchpad), `launchpad_token` for exclusion logic

### Final aggregation
- **Combining components**: The fund transfer data contains all necessary information from the dimension tables through joins, providing launchpad context and token mappings for each transfer event
- **Currency conversion**: Applies USD conversion using end-of-day price feeds and corrects token amounts based on decimal precision for accurate value calculation
- **Time aggregation**: Groups transfers by daily boundaries using timestamp truncation, ensuring consistent daily volume reporting
- **Final calculation**: Sums all USD-converted transfer amounts per day, applies zero-filling for periods with no activity, and includes project metadata (chain: NEAR, business line: Launchpad, market sector: infrastructure). The result represents total daily trading volume as measured by capital raised through Calyx launchpads.
