Functions ¶

func MakeSpecularEVMPreTransferHook ¶

func MakeSpecularEVMPreTransferHook(l2ChainId uint64, l1FeeRecipient common.Address) vm.EVMHook

MakeSpecularEVMPreTransferHook creates specular's vm.EVMHook function which is injected into the EVM and runs before every transfer currently this is only used to calculate & charge the L1 Fee

func MakeSpecularL1FeeReader ¶

func MakeSpecularL1FeeReader(l2ChainId uint64) vm.EVMReader

MakeSpecularL1FeeReader creates specular's vm.EVMReader function which is injected into the EVM and can be used to return the L1Fee of a transaction. This is a read only method and does not change the state.

func ScaleBigInt ¶

func ScaleBigInt(num *big.Int, scalar float64) *big.Int

multiply a big.Int with a float only the first 3 decimal places of the scalar are used to guarantee precision

Types ¶

type RollupConfig ¶

type RollupConfig interface {
	GetL1FeeRecipient() common.Address // recipient of the L1 Fee
	GetL2ChainID() uint64              // chain ID of the specular rollup
}
