# Celo L2 Contract deployers Methodology

## 1. Overview

Contract deployers for Celo L2 is measured as the number of unique addresses that have successfully deployed at least one smart contract. This metric is utilized as a proxy for identifying the volume of independent developers or entities actively publishing code onchain. By tracking these addresses, the scale of developer engagement and the growth of the application ecosystem on Celo L2 are quantified.

## 2. Data sources

- **Blockchain events**: Contract creation metadata covering Celo L1 (legacy)

## 3. Step-by-step calculation

### Component A: Contract creation identification

- **Purpose**: To identify all instances of smart contract deployments on the network
- **Logic**: Smart contract deployment records are retrieved from the blockchain. For each deployment, the `deployer_address` and `creation_timestamp` are extracted to identify the entity responsible for the code publication and the timing of the event. Distinct records are maintained to ensure account and contract addresses are accurately mapped to their respective creation traces.
- **Key fields**: `deployer_address`, `creation_timestamp`, and `contract_address`

### Component B: Daily unique deployer aggregation

- **Purpose**: To calculate the daily count of unique developers or entities
- **Logic**: The `deployer_address` field is aggregated using a distinct count grouped by day. This ensures that an address is only counted once per UTC day, regardless of the number of contracts published by that entity within the period. The calculation is specifically applied to data recorded on or after March 26, 2025, which corresponds to the Celo L2 architecture. To ensure data continuity, missing days are filled with zero values.
- **Key fields**: `timestamp` and `contract_deployers`

Blockchains (L2)

Validators process transactions and receive fees from users (supply-side fees).

Celo is a smart contract platform for decentralized applications (a blockchain). Celo was founded by Rene Reinsberg and Marek Olszewski and launched in 2020.

CELO holders own and govern the protocol. They currently take a cut of the total transaction fees paid by users (revenue). Celo's investors include a16z, Greenfield, Electric Capital, etc.
