Facet Transactions
Facet Transaction Format
Facet Transactions are similar to ordinary EIP-1559 Ethereum transactions as well as Optimism's Deposit transactions. Facet transactions have the EIP-2718 transaction type 0x46 (70 in base 10) and have the following fields:
chain_id
: distinguishes the payload as being relevant only to Facetmainnet
chain_id
will be0x0face7
testnet
chain_id
will be0x0face7a
to
: L2 recipient's address, be it an EOA or L2 contract. Blank for contract creations.value
: amount of FCT being transferred in the transactionmax_fee_per_gas
: max fee user is willing to pay per unit of gas for transaction inclusion in a blockgas_limit
: The gas limit of the L2 transactiondata
: EVM input data, i.e., ABI encoded contract call or contract creation code.mine_boost
(optional): Appended data that increases payload size to increase the amount of FCT mined by a transaction (see below).
Facet transactions have no signature field. Their "from" is inferred from the properties of the Ethereum transaction in which they are delivered.
Facet transactions must be serialized in this format for Facet nodes to process them:
Sending Facet Transactions
There are two ways to make a Facet transaction reach a Facet node for inclusion in a block:
