eth_getCode on Core
Everything below was measured on 2026-10-13 by calling eth_getCode on Core 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 Core
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) | not deployed |
| 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
Missing on Core: Safe singleton factory, which deploys Safe contracts at their canonical addresses. Tools that assume these exist will fail here until someone deploys them, which anyone can do for the keyless and CREATE2 ones.
Across the chains we measure
49 of 55 chains have all seven. Every one has Multicall3.

Frequently asked questions
Does Core support eth_getCode?
Yes. eth_getCode answered on the SwiftNodes Core endpoint when our weekly probe called it through the customer path (2026-10-13).
Is Permit2 deployed on Core?
Yes, at 0x000000000022D473030F116dDEE9F6B43aC78BA3 (checked 2026-10-13).
Does Core support ERC-4337?
The EntryPoint v0.7 contract is deployed at 0x0000000071727De22E5E9d8BAf0edAc6f37da032. You also need a bundler for Core.
Core endpoints, live block height and WebSocket status are on the Core RPC page.
One key covers every chain we serve, and SwiftNodes has a free tier.
