# Acala EVM Contracts deployed Methodology

## 1. Overview

Contracts deployed measures the number of unique smart contracts published onchain within the Acala EVM environment. This metric serves as a proxy for the volume of new infrastructure, protocols, and applications launched by developers. By tracking the initial creation of smart contracts, the growth and adoption of the Acala EVM ecosystem are quantified over time.

## 2. Data sources

- **Blockchain events**: `Executed` events from the `evm` pallet on Acala

## 3. Step-by-step calculation

### Component A: Acala EVM contract extraction

- **Purpose**: Identify successful smart contract deployment events within the Acala EVM pallet.
- **Logic**: Successful `Executed` events are parsed from the `evm` pallet on the Acala chain. For each valid event, the deployed contract address and the deployer address are extracted from the event data array. Only transactions with a valid extrinsic ID and a successful execution status are included.
- **Key fields**: `event_data` (containing contract and deployer addresses), `block_timestamp` (timing)

### Component B: Unique contract identification

- **Purpose**: Ensure each smart contract is only counted at the time of its initial deployment.
- **Logic**: The first occurrence of each unique contract address is identified by finding the minimum timestamp associated with that address across the historical dataset. This process ensures that each contract is attributed only to its original creation date and prevents the metric from being inflated by subsequent interactions or redeployments of existing addresses.
- **Key fields**: `contract_deployed` (unique address identifier), `block_timestamp` (earliest recorded timestamp)

### Component C: Daily aggregation and normalization

- **Purpose**: Generate a continuous daily time series of new contract deployments.
- **Logic**: The uniquely identified contract deployments are aggregated by day. The count of distinct contract addresses is calculated for each UTC day boundary. A zero-filling strategy is applied to ensure a value is recorded for every date in the time series, maintaining data continuity even on days when no new contracts are deployed.
- **Key fields**: `contracts_deployed` (distinct count of addresses), `timestamp` (daily granularity)

Collators aggregate parachain transactions block candidates and producing state transition proofs for validators based on those blocks.

Acala is a specialized stablecoin and liquidity blockchain powered by Polkadot Relay chain.

ACA holders own and govern the protocol. Acala’s investors include Pantera Capital, Coinbase Ventures, and Polychain Capital.
