CommonConfig is the common configuration for all chain providers

func (*CommonConfig) ContractsAddress

func (pc *CommonConfig) ContractsAddress() types.ContractConfigMap

func (*CommonConfig) Enabled

func (c *CommonConfig) Enabled() bool

Enabled returns true if the provider is enabled

func (*CommonConfig) GetWallet

func (pc *CommonConfig) GetWallet() string

func (*CommonConfig) SetWallet

func (pc *CommonConfig) SetWallet(addr string)

func (*CommonConfig) Validate

func (pc *CommonConfig) Validate() error

type Config

type Config interface {
	NewProvider(context.Context, *zap.Logger, string, bool, string) (ChainProvider, error)
	SetWallet(string)
	GetWallet() string
	Validate() error
	Enabled() bool
	ContractsAddress() types.ContractConfigMap
