Crate signet_constants 

Signet system constants.

This crate contains the system constants for Signet chains, including the host and rollup system contracts, pre-deployed tokens, etc.

Modules

gouda

Gouda testnet chain constants. Constants for the Gouda testnet (runs on the Parmigiana host chain).

mainnet

Mainnet chain constants. Constants for the Mainnet.

parmigiana

Parmigiana testnet chain constants. Constants for the Parmigiana testnet.

pecorinoDeprecated

Pecorino testnet chain constants. Constants for the Pecorino testnet.

test_utils

Test utilities for chains. Constants for local testnet chains.

Structs

HostConstants

System addresses and other configuration details on the host chain.

HostTokens

Host tokens configuration for the rollup.

HostUsdRecord

A host-chain USD record, which contains the address of the token and its decimals./s

PairedHeights

A pair of heights, one for the host chain and one for the rollup chain.

RollupConstants

Configuration details for the rollup chain.

RollupTokens

Rollup tokens configuration for the rollup.

SignetConstants

All constants pertaining to the Signet system.

SignetEnvironmentConstants

Signet Environment constants.

SignetSystemConstants

Signet constants.

UsdRecords

A set of USD records, which can hold up to 5 records. 5 is chosen as a reasonable limit for the number of USD tokens that can be predeployed on the host chain. This limit is arbitrary but should be sufficient for most use cases, and can be adjusted trivially if needed.

Enums

ConfigError

Captures errors related to loading configuration from the environment or other sources.

HostPermitted

Permissioned tokens for the host chain.

KnownChains

Known chains for the Signet system.

ParseChainError

Error type for parsing struct from a chain name.

RollupPermitted

Permissioned tokens for the rollup.

Constants

MINTER_ADDRESS

System address with permission to mint tokens. This is the address from which the node will issue transactions to mint ETH or ERC20 tokens.

NATIVE_TOKEN_ADDRESS

Placeholder address for the native token of the current chain. By convention this is 0xee....
