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

Cardano is a smart contract platform for decentralized applications (a blockchain). Cardano was founded by Charles Hoskinson & Jeremy Wood and launched in 2017.

ADA holders own and govern the protocol. They currently do not take a cut of the total transaction fees paid by users (revenue).

# Cardano Contracts deployed Methodology

## 1. Overview

Contracts deployed measures the number of unique smart contracts published onchain for Cardano. It is used as a proxy for the volume of new infrastructure and decentralized applications being launched within the ecosystem. This metric provides insight into developer activity and the expansion of the programmable utility of the network.

## 2. Data sources

- **Blockchain events**: Contract creation records from onchain ledger data, covering Cardano

## 3. Step-by-step calculation

### Component A: Contract creation extraction

- **Purpose**: Capture the deployment of new smart contracts on the network.
- **Logic**: Individual contract deployment events are identified from the onchain registry. For each entry, the `creation_timestamp` and the unique `contract_address` are extracted to identify the specific code deployment and its timing.
- **Key fields**: `creation_timestamp`, `contract_address`

### Component B: Daily aggregation and deduplication

- **Purpose**: Calculate the total number of unique contracts launched per day.
- **Logic**: The number of unique `contract_address` entries is counted and truncated to daily granularity based on the UTC timestamp of the block in which they were created. The resulting dataset is processed to ensure that any days without activity are zero-filled to maintain a continuous time series. Data is further filtered to match the verified availability and freshness parameters of the Cardano chain.
- **Key fields**: `timestamp`, `contracts_deployed` (distinct count of addresses)
