# Contracts

The contracts table contains all the deployed contracts with bytecode data identified from trace `create` and `create2` opcodes.

A "smart contract" is simply a program that runs on the EVM blockchain. It's a collection of code (its functions) and data (its state) that resides at a specific address on the blockchain.

Deploying a smart contract on EVM chains typically involves sending a transaction containing the compiled code of the smart contract without specifying any recipient.
