type Chains 

type Chains struct {
	EVM      evm.ChainSet
	Cosmos   cosmos.ChainSet   // nil if disabled
	Solana   solana.ChainSet   // nil if disabled
	StarkNet starknet.ChainSet // nil if disabled
}

Chains holds a ChainSet for each type of chain.

type Config 

type Config struct {
	config.Core

	EVM evmcfg.EVMConfigs `toml:",omitempty"`

	Cosmos cosmos.CosmosConfigs `toml:",omitempty"`

	Solana solana.SolanaConfigs `toml:",omitempty"`

	Starknet starknet.StarknetConfigs `toml:",omitempty"`
}

Config is the root type used for TOML configuration.

See docs at /docs/CONFIG.md generated via config.GenerateDocs from /internal/config/docs.toml

When adding a new field:

  • consider including a unit suffix with the field name
  • TOML is limited to int64/float64, so fields requiring greater range/precision must use non-standard types implementing encoding.TextMarshaler/TextUnmarshaler, like utils.Big and decimal.Decimal
  • std lib types that don't implement encoding.TextMarshaler/TextUnmarshaler (time.Duration, url.URL, big.Int) won't work as expected, and require wrapper types. See models.Duration, models.URL, utils.Big.

func (*Config) SetFrom 

func (c *Config) SetFrom(f *Config)

func (*Config) TOMLString 

func (c *Config) TOMLString() (string, error)

type GeneralConfig 

type GeneralConfig interface {
	config.GeneralConfig
	v2.HasEVMConfigs
	CosmosConfigs() cosmos.CosmosConfigs
	SolanaConfigs() solana.SolanaConfigs
	StarknetConfigs() starknet.StarknetConfigs
	// ConfigTOML returns both the user provided and effective configuration as TOML.
	ConfigTOML() (user, effective string)
}

type GeneralConfigOpts 

type GeneralConfigOpts struct {
	Config
	Secrets

	// OverrideFn is a *test-only* hook to override effective values.
	OverrideFn func(*Config, *Secrets)

	SkipEnv bool
}

GeneralConfigOpts holds configuration options for creating a coreconfig.GeneralConfig via New().

See ParseTOML to initilialize Config and Secrets from TOML.
