Functions ¶

func MakeSpecularEVMPreTransferHook ¶

func MakeSpecularEVMPreTransferHook(cfg RollupConfig) 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 RegisterGethRollupServices ¶

func RegisterGethRollupServices(
	stack Node,
	cliCtx *cli.Context,
	eth api.ExecutionBackend,
	proofBackend proof.Backend,
) error

TODO: remove this when EL and CL client are decoupled. Creates rollup services and registers them as Geth services.

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 Node ¶

type Node interface {
	RegisterLifecycle(lc node.Lifecycle)
	AccountManager() *accounts.Manager
}

type RollupConfig ¶

type RollupConfig interface {
	GetAccountAddr() common.Address      // recipient of the L1 Fee
	GetChainID() uint64                  // chain ID of the specular rollup
	GetL1FeeOverhead() int64             // fixed cost of submitting a tx to L1
	GetL1FeeMultiplier() float64         // value to scale the L1 Fee
	GetL1OracleAddress() common.Address  // contract providing the L1 basefee
	GetL1OracleBaseFeeSlot() common.Hash // L1 basefee storage slot
}
