Types

type Chain 

type Chain struct {
	ID   uint64 // Chain ID asa per https://chainlist.org
	Name string // Chain name as per https://chainlist.org
	// RPCURL            string            // RPC URL of the chain
	PortalAddress     common.Address    // Address of the omni portal contract on the chain
	DeployHeight      uint64            // Height that the portal contracts were deployed
	BlockPeriod       time.Duration     // Block period of the chain
	FinalizationStrat FinalizationStrat // Finalization strategy of the chain
}

Chain defines the configuration of an execution chain that supports the Omni cross chain protocol. This is most supported Rollup EVMs, but also the Omni EVM, and the Omni Consensus chain.

func (Chain) ConfLevels 

func (c Chain) ConfLevels() []xchain.ConfLevel

ConfLevels returns the uniq set of confirmation levels supported by the chain. This is inferred from the supported shards.

func (Chain) Shards 

func (c Chain) Shards() []uint64

Shards returns the supported shards for the chain. TODO(corver): Store these in XRegistry, currently it is inferred from the FinalizationStrat.

type Deployment 

type Deployment struct {
	ChainID      uint64
	Address      common.Address
	DeployHeight uint64
}

type FinalizationStrat added in v0.1.0 

type FinalizationStrat string

FinalizationStrat defines the finalization strategy of a chain. This is mostly ethclient.HeadFinalized, but some chains may not support it, like zkEVM chains which would need a much more involved strategy.

func (FinalizationStrat) ConfLevel added in v0.1.8 

func (h FinalizationStrat) ConfLevel() xchain.ConfLevel

ConfLevel returns the confirmation level of the finalization strategy. TODO(corver): Replace FinalizationStrat with ConfLevel completely.

func (FinalizationStrat) String added in v0.1.4 

func (h FinalizationStrat) String() string

func (FinalizationStrat) Verify added in v0.1.0 

func (h FinalizationStrat) Verify() error

type ID 

type ID string

ID is a network identifier. 

const (
	// Simnet is a simulated network for very simple testing of individual binaries.
	// It is a single binary with mocked clients (no networking).
	Simnet ID = "simnet" // Single binary with mocked clients (no network)

	// Devnet is the most basic single-machine deployment of the Omni cross chain protocol.
	// It uses docker compose to setup a network with multi containers.
	// E.g. 2 geth nodes, 4 halo validators, a relayer, and 2 anvil rollups.
	Devnet ID = "devnet"

	// Staging is the Omni team's internal staging network, similar to a internal testnet.
	// It connects to real public rollup testnets (e.g. Arbitrum testnet).
	// It is deployed to GCP using terraform.
	// E.g. 1 Erigon, 1 Geth, 4 halo validators, 2 halo sentries, 1 relayer.
	Staging ID = "staging"

	// Testnet is the Omni public testnet.
	Testnet ID = "testnet"

	// Mainnet is the Omni public mainnet.
	Mainnet ID = "mainnet"
)

func All 

func All() []ID

All returns all the supported network IDs.

func (ID) IsEphemeral 

func (i ID) IsEphemeral() bool

IsEphemeral returns true if the network is short-lived, therefore ephemeral.

func (ID) IsProtected 

func (i ID) IsProtected() bool

IsProtected returns true if the network is long-lived, therefore protected.

func (ID) Static 

func (i ID) Static() Static

Static returns the static config and data for the network.

func (ID) String 

func (i ID) String() string

func (ID) Verify 

func (i ID) Verify() error

func (ID) Version added in v0.1.3 

func (i ID) Version() string

type Network 

type Network struct {
	ID     ID      `json:"name"`   // ID of the network. e.g. "simnet", "testnet", "staging", "mainnet"
	Chains []Chain `json:"chains"` // Chains that are part of the network
}

Network defines a deployment of the Omni cross chain protocol. It spans an omni chain (both execution and consensus) and a set of supported rollup EVMs.
