Differences between Ethereum and Linea

EVM opcodes

important Linea uses the London version of the Ethereum Virtual Machine

(EVM). All EVM opcodes are managed identically to Ethereum London unless presented in the following table.

Solidity 8.23 and later compiles newer versions of the EVM by default. Use the solc --evm-version london command to ensure compatibility with Linea. :::

⚠️ At the moment we do not support the eth_newFilter and eth_newBlockFilter RPC calls.

Opcode name	Ethereum	Linea	Explanation
BLOBHASH	Returns a versioned hash.	n/a	Unavailable on Linea due to being introduced in the Cancun upgrade.
BLOBBASEFEE	Returns the value of the blob base-fee of the current block.	n/a	Unavailable on Linea due to being introduced in the Cancun upgrade.
DIFFICULTY/PREVRANDAO	Returns the RANDAO value from the previous block	Returns a fixed number: 2	In Ethereum, PREVRANDAO was previously known as DIFFICULTY. It was renamed to PREVRANDAO in EIP-4399 and its functionality changed due to the switch from PoW to PoS. PREVRANDAO returns a full 256-bit value that represents the randomness beacon output of the previous block. For more, see the 'Security Considerations' section of EIP-4399.
MCOPY	Copies memory areas, allowing the destination and source to overlap.	n/a	Unavailable on Linea due to being introduced in the Cancun upgrade.
PUSH0	Pushes the constant value 0 onto the stack	n/a	PUSH0 was introduced in the Ethereum Mainnet Shanghai upgrade and became available in Solidity compiler version 0.8.20, which came after the London release. However, Linea currently supports compiled code targeting the London release of the Ethereum Mainnet. Using the EVM Version of London when compiling, or using Solidity compiler 0.8.19 or lower will align with Linea's capabilities.
TLOAD	Load word from transient storage.	n/a	Unavailable on Linea due to being introduced in the Cancun upgrade.
TSTORE	Save word to transient storage.	n/a	Unavailable on Linea due to being introduced in the Cancun upgrade.

Evmdiff is also a useful resource for comparing Linea with Ethereum.

Precompiles

Precompiles as transaction recipients

On Linea, transactions cannot set the recipient of a transaction (the address in to) as a precompile. The to address of transactions cannot be in the range 0x01-0x09.

MODEXP

MODEXP (0x05) on Linea currently only supports arguments (base, exponent, modulus) that do not exceed 512-byte integers.

Point evaluation

The point evaluation precompile was introduced in EIP-4844, and is therefore unavailable on Linea.

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.
