Liquidity providers deposit funds into DODO and receive trading fees from traders (supply-side fees).

DODO is a non-custodial exchange protocol built on Ethereum and other blockchains. DODO launched in 2020.

DODO tokenholders own and govern the protocol. They currently take a cut of the total trading fees paid by traders (revenue). DODO's investors include Pantera Capital, Three Arrows Capital, Binance Labs, etc.

# DODO Tradeable pairs Methodology

## 1. Overview

Tradeable pairs measures the number of unique token pairs available for trading on the decentralized exchange. It reflects the number of direct swap routes offered by the project. The growth of trading options available to users is tracked by counting distinct asset pairs that have been actively traded or created as pools on the platform. The first appearance of each trading pair is identified, and a running cumulative count is maintained to provide insight into the expansion of DODO's trading ecosystem across multiple blockchain networks.

## 2. Data sources

- **Blockchain events**: `DODOBirth` events from `Zoo` contracts, `BuyBaseToken` and `SellBaseToken` events from `USTPair` contracts, and `DODOSwap` events from `VendingMachine`, `StablePool`, `PrivatePool`, and `GasSavingPool` contracts, covering Ethereum, Arbitrum, Base, Polygon, and 3 other chains
- **External data**: Asset metadata including symbols and decimal precision

## 3. Step-by-step calculation

### Component A: Trading pair identification

- **Purpose**: Extract all unique trading pairs from DODO events across multiple chains and protocol versions
- **Logic**: Different types of DODO events are processed to identify trading pairs. For DODO V1, pool addresses and asset pairs are extracted from `DODOBirth` events from `Zoo` contracts, which signal new pool creation, using the `newBorn` field for pool address and `baseToken` and `quoteToken` fields for the trading pair. Special cases like `BuyBaseToken` and `SellBaseToken` events from `USTPair` contracts on Ethereum are handled where specific asset addresses are hardcoded for USDT trading pairs. For DODO V2, `DODOSwap` events from `VendingMachine`, `StablePool`, `PrivatePool`, and `GasSavingPool` contracts are analyzed, with the pool contract address and asset pair extracted from `fromToken` and `toToken` fields. Data is combined across all supported chains and enriched with asset metadata to create readable pair names using asset symbols.
- **Key fields**: `block_timestamp` for timing, `account_address` for pool identification, `token0_address` and `token1_address` for trading pairs, `chain` for network identification, `version` for protocol version

### Component B: First appearance tracking

- **Purpose**: Determine when each unique trading pair first became available on DODO
- **Logic**: All trading pair records are grouped by pool address and chain, and the minimum `block_timestamp` is identified for each unique combination. Timestamps are truncated to daily granularity to establish the first day each trading pair appeared. A dataset of first appearances is created to count new pairs added each day.
- **Key fields**: `timestamp` (truncated to day), `chain` for network grouping, `account_address` for unique pair identification

### Component C: Daily aggregation

- **Purpose**: Count new trading pairs added each day and ensure continuous time series
- **Logic**: First appearances are grouped by date and chain, and distinct pool addresses are counted to obtain the number of new pairs introduced each day. Missing dates are filled with zero values when no new pairs were introduced to ensure a continuous daily time series of new pair additions is created for each chain.
- **Key fields**: `timestamp` for daily buckets, `chain` for partitioning, `pair_count` for daily new additions

### Component D: Cumulative aggregation

- **Purpose**: Convert daily new pair counts into a running cumulative total of tradeable pairs
- **Logic**: A cumulative sum is calculated over the daily new pair counts, partitioned by chain and ordered chronologically by timestamp. The cumulative number of unique trading pairs that have ever appeared on DODO for each chain up to each given date is represented by this running total. Chain availability filters are applied to ensure only active and supported chains are included in the final output.
- **Key fields**: `timestamp` for daily buckets, `chain_id` for partitioning, `tradeable_pairs` for cumulative count
