# Acala EVM Contract deployers Methodology

## 1. Overview

Contract deployers measures the number of unique addresses that have deployed at least one smart contract on Acala EVM. This metric is utilized as a proxy for the number of independent developers or entities that are actively publishing code on-chain. The activity of developers is captured by identifying successful contract creation events within the Acala EVM emulation layer.

## 2. Data sources

- **Blockchain events**: `Executed` events from the `evm` pallet, covering Acala Substrate

## 3. Step-by-step calculation

### Component A: Acala EVM deployment tracking

- **Purpose**: Identify successful smart contract deployments within the Acala EVM environment
- **Logic**: `Executed` events are parsed from the `evm` pallet on Acala Substrate. Deployment data is extracted from the event parameters to identify the address of the deployer and the address of the newly created contract. The dataset is restricted to successful transactions where a valid extrinsic identifier is present.
- **Key fields**: `contract_deployer`, `contract_deployed`, `block_timestamp`

### Component B: Unique deployer aggregation

- **Purpose**: Deduplicate deployment activity to count unique developer entities
- **Logic**: Deployment records are partitioned by the address of the deployed contract to ensure each contract creation is uniquely identified. The distinct number of deployer addresses is then calculated and aggregated at a daily granularity. This process ensures that multiple contract deployments by the same address within a single day are counted as one unique deployer.
- **Key fields**: `contract_deployer`, `timestamp`

### Component C: Normalization and zero-filling

- **Purpose**: Standardize data for institutional-grade reporting and ensure time-series continuity
- **Logic**: Daily counts are normalized into a standardized schema and associated with the Acala EVM product identifier. Any gaps in the time series are addressed by applying a zero-filling strategy, ensuring a value is recorded for every day. Data is further filtered to ensure only records up to the last approved timestamp for the chain are included in the final output.
