# Celo L2 Contracts deployed Methodology

## 1. Overview

Contracts deployed measures the number of unique smart contracts published onchain on Celo L2. This metric serves as a proxy for the volume of new infrastructure, protocols, and decentralized applications launched within the ecosystem. By tracking the deployment of unique contract bytecodes, the activity of developers and the expansion of the network's programmable surface area are quantified.

## 2. Data sources

- **Blockchain events**: Contract creation data including contract addresses, deployment timestamps, and bytecodes from Celo L2
- **External data**: None required for this metric

## 3. Step-by-step calculation

### Component A: Contract creation extraction

- **Purpose**: Identify every unique smart contract successfully deployed to the blockchain.
- **Logic**: Distinct contract deployment records are retrieved from the blockchain ledger. For each deployment, the `contract_address`, `creation_timestamp`, `deployer_address`, and `contract_bytecode` are extracted to ensure a complete record of onchain initialization.
- **Key fields**: `contract_address`, `creation_timestamp`

### Component B: Temporal filtering for Celo L2

- **Purpose**: Isolate deployment activity specifically occurring on the Celo L2 infrastructure.
- **Logic**: Deployment records are filtered by timestamp to distinguish between legacy and current network iterations. All contract creations occurring on or after March 26, 2025, are attributed to Celo L2.
- **Key fields**: `block_timestamp`

### Component C: Daily aggregation and normalization

- **Purpose**: Generate a daily time series of deployment activity.
- **Logic**: The total count of unique contract addresses is aggregated with a daily granularity based on UTC day boundaries. Data types are cast to bignumeric to ensure precision. A zero-filling sequence is applied to the time series to ensure that days with no deployment activity are explicitly recorded as zero.
- **Key fields**: `contracts_deployed` (count), `timestamp` (daily truncation)

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.
