This document describes the structure and purpose of the `contracts` table within the databases.
The table stores metadata and deployment details of smart contracts.
## 📌 Table Description
Each record stored in the table has the following structure and fields, with described constraints.
| Column Name | Type | Constraints | Description - |
|---------------------|------------|---------------------|-----------------------------------------------------------------------------|
| `address` | TEXT | PRIMARY KEY | The unique address of the smart contract on the blockchain. |
| `creator` | TEXT | NOT NULL | The address of the account that deployed the contract. |
| `creation_tx` | TEXT | NOT NULL | The transaction hash that created the contract. |
| `creation_time` | TIMESTAMP | NOT NULL | The timestamp when the contract was deployed. |
| `creation_block` | INTEGER | NOT NULL | The block number in which the contract was created. |
| `name` | TEXT | NULLABLE | The human-readable name of the contract, if available. |
| `source_code` | TEXT | NULLABLE | The full Solidity source code of the contract. |
| `abi` | TEXT | NULLABLE | The Application Binary Interface (ABI) of the contract. |
| `compiler_version` | TEXT | NULLABLE | The Solidity compiler version used to compile the contract. |
| `evm_version` | TEXT | NULLABLE | The targeted Ethereum Virtual Machine (EVM) version. |
| `optimization_used` | BOOLEAN | NULLABLE | Indicates whether compiler optimizations were enabled. |
| `runs` | INTEGER | NULLABLE | Number of optimization runs used during compilation. |
| `constructor_args` | TEXT | NULLABLE | Encoded constructor arguments passed during deployment. |
| `library` | TEXT | NULLABLE | Linked library information, if any. |
| `license` | TEXT | NULLABLE | License type of the source code (e.g., MIT, GPL-3.0). |
| `is_proxy` | BOOLEAN | NULLABLE | Flag indicating whether the contract is a proxy. |
| `implementation` | TEXT | NULLABLE | Address of the implementation contract, if this is a proxy. |
| `swarm_source` | TEXT | NULLABLE | Swarm hash / metadata URL pointing to the source code bundle. |
📝 Notes:
- The **primary key** `address` ensures uniqueness for each deployed contract in the corresponding chain.
- `creation_tx`, `creation_time`, and `creation_block` stores contract’s deployment information, i.e. transaction id, timestamp, and block number.
- `source_code`, `abi`, and `compiler_version` are typically available when the contract has been verified.
- Proxy patterns are identified through `is_proxy` and `implementation`.
## 🧱 Table Definition
```sql
CREATE TABLE IF NOT EXISTS contracts (
address TEXT PRIMARY KEY,
creator TEXT NOT NULL,
creation_tx TEXT NOT NULL,
creation_time TIMESTAMP NOT NULL,
creation_block INTEGER NOT NULL,
name TEXT,
source_code TEXT,
abi TEXT,
compiler_version TEXT,
evm_version TEXT,
optimization_used BOOLEAN,
runs INTEGER,
constructor_args TEXT,
library TEXT,
license TEXT,
is_proxy BOOLEAN,
implementation TEXT,
swarm_source TEXT
);
```
## 🧭 Usage Example
```sql
SELECT address, name, compiler_version, source_code
FROM contracts
WHERE source_code IS NOT NULL AND source_code != ""
ORDER BY creation_block DESC
LIMIT 10;
```
This query returns the 10 most recently deployed contracts with available **source code** along with their addresses, names and compiler versions.
