Opcodes

All opcodes are supported in UniFi and are EVM equivalent unless stated otherwise.

Modified Opcodes

Opcode	Name	Solidity Equivalent	Rollup Behaviour	Ethereum L1 Behaviour
32	ORIGIN	tx.origin	If the transaction is an L1 ⇒ L2 transaction triggered by a smart contract on L1, then tx.origin is set to the aliased address of the address that triggered the L1 ⇒ L2 transaction. Otherwise, this opcode behaves normally.	Get execution origination address
33	CALLER	msg.sender	If the transaction is an L1 ⇒ L2 transaction triggered by a smart contract on L1, and this is the first call frame (rather than an internal transaction from one contract to another), the same address aliasing behavior applies.	Get caller address
41	COINBASE	block.coinbase	Returns the address of the L2 block proposer	Gets the block's beneficiary address
42	TIMESTAMP	block.timestamp	Timestamp of the L2 block	Timestamp of the L1 block
43	NUMBER	block.number	L2 block number	Gets the L1 block number
44	PREVRANDAO	block.prevrandao	Returns the PREVRANDAO (the most recent RANDAO) value of L1 at the current L1 origin block	Returns the output of the randomness beacon provided by the beacon chain
49	BLOBHASH	blobhash(index)	N/A	Get versioned hashes
4A	BLOBBASEFEE	block.blobasefee	Returns 1	Returns the value of the blob base-fee of the current block
