How this service works
CREATE2 deterministic contract address calculator — derive the EIP-1014 EVM deployment address, preimage, hashes, and EIP-55 checksum offline without RPC.
Output
Returns the deterministically computed EVM contract address per EIP-1014, the EIP-55 checksummed form of that address, the raw preimage bytes (0xff ++ deployer ++ salt ++ keccak256(initcode)), and intermediate keccak256 hashes — all computed offline without an RPC call.
Example use cases
Pre-deployment address verification
“Before I deploy my contract factory, can you compute the CREATE2 address I'll get if the deployer is 0xDe1C2f5F37a6b59A6B7a3D5C8eEb5c9f38E3Aa1, salt is 0x000000000000000000000000000000000000000000000000000000000000dead, and my initcode hash is 0xabcdef1234567890abcdef1234567890abcdef1234567890abcdef1234567890ab? I need the EIP-55 address and preimage.”
Cross-chain deterministic deployment check
“I'm deploying the same contract to multiple EVM chains using CREATE2. Can you derive the expected address for deployer 0x4e59b44847b379578588920cA78FbF26c0B4956C, salt 0x0000000000000000000000000000000000000000000000000000000000000042, and initcode hash 0xbc36789e7a1e281436464229828f817d6612f7b477d66591ff96a9e064bcc98a without hitting any RPC?”
Smart contract wallet address precomputation
“I need to precompute the address of a smart account before it's deployed — the factory is at 0xFB6916095ca1df60bB79Ce92cE3Ea74c37c5d359, the salt is the user's address packed as bytes32: 0x000000000000000000000000abcdef1234567890abcdef1234567890abcdef12, and the initcode hash is 0xd6aca1be9729c13d677335161321649cccae6a591554772516700f986f942eaa. Give me the checksummed CREATE2 address and the keccak256 preimage.”
Technical details
Endpoint
POSThttps://chain-tools.use.x402atlas.com/evm/create2When to prefer
Choose this endpoint when you need to deterministically predict a CREATE2 contract deployment address before deployment, without needing a live RPC node. Ideal for cross-chain deployments, factory contract patterns, smart account address precomputation, or any workflow that must know the contract address ahead of time. Prefer this over on-chain calls when you need offline, reproducible, cryptographically verifiable computation of EIP-1014 addresses.
Side effects
- Invalid deployer address format — must be a valid 20-byte hex address
- Salt not 32 bytes — must be exactly 32 bytes hex-encoded
- Missing or malformed initcode or initcode hash input
- Malformed hex strings causing computation failure
- Unsupported or missing required fields returning 400 Bad Request
