Differences between Ethereum and Linea

This page outlines Ethereum Mainnet functionality that differs on Linea, or is not yet available on Linea. Absence from this page indicates that the functionality is available on Linea and identical to behavior on Ethereum Mainnet; if you're experiencing otherwise, please get in touch via Discord.

note

With Linea Beta v4, Linea upgraded to the Pectra hard fork.

EVM opcodes

Opcode	Ethereum	Linea
BLOBBASEFEE	Returns the value of the blob base-fee of the current block.	Will always return the minimum value.
BLOBHASH	Given an an input in the form of an index, indicating the position of a particular blob within an array of blobs associated with a transaction, returns the hash of the corresponding blob. If the index is out of bounds, returns 0.	Will always return 0.
BLOCKHASH	Returns the hash of a requested block from the 256 most recent blocks.	Returns the correct value, but the value is not guaranteed by the proof (Linea is a type 2 zkEVM, and uses/proves an L2-specific state representation).
PREVRANDAO	Returns the RANDAO value from the previous block.	Use a formula similar to Ethereum, e.g. L2_prevrandao XOR hash(signed(slot_id)).

Consult the Ethereum Foundation's Opcode Reference for more.

Evmdiff is also a useful resource for comparing Linea with Ethereum, and evm.codes is useful for information about specific opcodes on Ethereum.

Precompiles

Precompile	Ethereum	Linea
BLAKE2f	Compression function F used in the BLAKE2 cryptographic hashing algorithm.	Not supported.
MODEXP	Arbitrary-precision exponentiation under modulo.	Only supports arguments (base, exponent, modulus) that do not exceed 512-byte integers.
Precompiles as transaction recipients	Applicable to various use cases.	Not supported. A transaction to address cannot be a precompile, i.e. an address in the range 0x01-0x09.
RIPEMD-160	A hash function.	Not supported.

Beacon root

EIP-4788, included in Ethereum's Dencun upgrade, introduced a smart contract that enables the caller to get or set the hash tree root of a beacon chain block.

This functionality is available with Linea Beta v4. However, due to the difference in block time when compared to Ethereum Mainnet, only the root of the previous block is available.

Call data

Linea's sequencer limits the size of call data, so that transactions can fit into the corresponding blob. The current limit is 60000 bytes.

JSON-RPC API

Linea uses the standard Ethereum JSON RPC API methods. However, in a few cases, methods differ from those on Ethereum. These methods are documented in the reference section, and include:

• linea_estimateGas
• linea_getProof
• linea_getTransactionExclusionStatusV1
• eth_sendRawTransaction

Type 3 transactions

Linea does not support type 3 (0x3 or "blob") transactions. This type is used on Ethereum Mainnet primarily for layer 2 rollups to cheaply post data on L1.

EIP-7702

EIP-7702 is not yet supported on Linea, and is scheduled to be activated with Beta v6.0, in early 2026.
