Bot Bazaar CREATE2 Address Calculator
x402
Bot Bazaar CREATE2 Address Calculator is a paid API for AI agents from bot-bazaar.fly.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).
Computes the exact deterministic EVM contract address that will be deployed via CREATE2 given a deployer address, salt, and initCodeHash.

How this service works
Compute the exact deterministic EVM contract address deployed via CREATE2 from deployer address, 32-byte salt, and initCodeHash.
Output
Returns the deterministic EVM contract address (0x-prefixed 20-byte hex address) that would result from a CREATE2 deployment with the given deployer address, salt, and initCodeHash — computed without any on-chain interaction.
Example use cases
Pre-fund counterfactual contract wallet
“Before I deploy my smart contract wallet, I need to know its CREATE2 address so I can pre-fund it — my deployer is 0x4e59b44847b379578588920cA78FbF26c0B4956C, salt is 0x000000000000000000000000000000000000000000000000000000000000abcd, and my initCodeHash is 0xabc123... Can you compute the deterministic address?”
Verify proxy factory deployment address
“I'm using a minimal proxy factory and need to confirm which address my contract will land at before deploying — the factory deployer is 0x1234...abcd, salt bytes32 is 0x0000...0001, and initCodeHash is 0xdeadbeef.... What's the CREATE2 address?”
Audit cross-chain address consistency
“We're deploying the same contract to multiple EVM chains using CREATE2 and need to verify the address will be identical everywhere — deployer 0xfactory...5678, salt 0xsalt...9999, initCodeHash 0xhash...cafe. Can you calculate the resulting address?”
Technical details
Endpoint
GEThttps://bot-bazaar.fly.dev/v1/x402/create2-address-calc?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to deterministically predict a CREATE2 contract address before deployment, especially for counterfactual contract instantiation, cross-chain address consistency checks, or pre-funding contracts. It is a pure off-chain computation — no RPC node, wallet, or on-chain call required, making it faster and cheaper than querying a node.
Side effects
- Missing or malformed deployer address returns an error
- Invalid or non-32-byte salt causes computation failure
- Malformed initCodeHash (not 32-byte keccak256 hex) returns an error
- Non-0x-prefixed addresses may cause parsing errors
- Payment not provided results in 402 Payment Required response
