# Flow Contract deployers Methodology

## 1. Overview

Contract deployers measures the number of unique addresses that have deployed at least one smart contract on Flow. This metric serves as a proxy for the number of independent developers or entities actively publishing code onchain. The metric accounts for development activity across both the native Cadence environment and the Flow EVM environment.

## 2. Data sources

- **Blockchain events**: `AccountContractAdded` events from `FlowSystemContract` contracts and contract creation traces, covering Flow

## 3. Step-by-step calculation

### Component A: Flow (Cadence) deployment tracking

- **Purpose**: Identify contract deployments within the Flow native (Cadence) environment.
- **Logic**: `AccountContractAdded` events are parsed from `FlowSystemContract` contracts. The address responsible for adding the contract and the associated code hash are extracted to identify unique deployment actions.
- **Key fields**: `deployer_address`, `block_timestamp`, `code_hash`

### Component B: Flow EVM deployment tracking

- **Purpose**: Identify contract deployments within the Flow EVM environment.
- **Logic**: Contract creation records are extracted from Flow EVM trace data. Distinct deployer addresses are identified from transactions involving contract instantiation.
- **Key fields**: `deployer_address`, `block_timestamp`

### Component C: Deduplication and daily aggregation

- **Purpose**: Consolidate deployment activity and calculate the daily unique count of developers.
- **Logic**: Deployer addresses from both the Cadence and EVM environments are combined into a unified dataset. The number of unique addresses is calculated at a daily granularity. Missing days are filled with zeros to ensure a continuous time series, and results are filtered based on chain data availability.
- **Key fields**: `timestamp`, `contract_deployers`

Blockchains (L1)

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

Flow is a smart contract platform for decentralized applications (a blockchain). Flow was founded by Roham Gharegozlou, Dieter Shirley and Mikhael Naayem and launched in 2019.

FLOW holders own and govern the protocol. They currently don’t take a cut of the total transaction fees paid by users (revenue). Flow’s investors include a16z, Coatue, Coinfund, Fabric Ventures, etc.
