eth_getCode

eth_getCode JSON-RPC reference for MegaETH.

Summary

Returns the runtime bytecode stored at an address at a given block.

The public MegaETH endpoint supports this method. The standard, node, and gateway layers below identify behavior that differs from a generic Ethereum endpoint.

Parameters

address Address REQUIRED

Target account or contract address.


block string

Hex block number, block hash, or tag (latest, safe, finalized, …). The default is "latest".

Result

result Data

Runtime bytecode (not creation bytecode) at the address; 0x when no code is deployed.

Comparison with Ethereum Standard JSON-RPC

Ethereum Standard

The canonical Ethereum method uses the parameter and result contract documented above, including the stated null, false, or zero-value semantics where applicable.

MegaETH Node Behavior

The node returns runtime bytecode from the selected state. A missing account and an account with no code are both represented by empty bytecode.

MegaETH Public Gateway

The gateway streams bytecode responses and caches successful fixed-state lookups for up to 30 minutes. The exact cache key follows the address and block selector.

Errors

The | Scope | column distinguishes method failures from gateway policy errors.
