📌 What Is a Precomputed Address?

A precomputed address is the future address of a smart contract that has not yet been deployed, but can be known in advance using the CREATE2 opcode.

Unlike the normal CREATE, which depends on a wallet’s nonce (not predictable by others), CREATE2 lets you generate a guaranteed contract address in advance based on:

• Deployer address (e.g., factory contract)
• A salt value (random or user-specific)
• Contract creation bytecode (including constructor args)

🔄 Why Use Precomputed Addresses?

🪄 Main Reason: You know the contract’s address before it's deployed

This lets you:

• Send ETH, tokens, NFTs to that address early
• Use it in off-chain logic
• Create gasless onboarding flows
• Build systems like counterfactual wallets, airdrops, and bridges

🚀 How the Flow Works

1. Predict the address

• Call a function like getAddress(owner, salt) on a factory contract.
• This returns the address where the smart contract will be deployed later.
