eth_getCode on Cronos
Everything below was measured on 2026-10-13 by calling eth_getCode on Cronos through the same endpoint customers use, and is re-measured weekly.
What eth_getCode does
Returns the deployed bytecode at an address, or 0x if there is none. It is how tools tell a contract from a wallet and check that a contract they depend on exists on a chain before calling it.
Standard contracts on Cronos
We called eth_getCode on the address each of these contracts has on every chain where it is deployed.
| Multicall3 (0xcA11bd…CA11) | deployed, 3,808 bytes |
|---|---|
| Permit2 (0x000000…8BA3) | deployed, 9,152 bytes |
| Deterministic deployment proxy (0x4e59b4…956C) | deployed, 69 bytes |
| Safe singleton factory (0x914d7F…43d7) | deployed, 69 bytes |
| ERC-4337 EntryPoint v0.7 (0x000000…a032) | deployed, 16,035 bytes |
| ERC-4337 EntryPoint v0.6 (0x5FF137…2789) | deployed, 23,689 bytes |
| CreateX (0xba5Ed0…a5Ed) | deployed, 11,838 bytes |
What this means
All 7 are deployed, so Foundry deterministic deploys, viem multicall, Permit2 approvals and ERC-4337 smart accounts work on Cronos without extra setup.
Across the chains we measure
49 of 55 chains have all seven. Every one has Multicall3.
