const DefaultConfigTemplate = `` /* 2960-byte string literal not displayed */

DefaultConfigTemplate defines the configuration template for the EVM RPC configuration

Functions

func AppConfig

func AppConfig(denom string) (string, interface{})

AppConfig helps to override default appConfig template and configs. return "", nil if no custom configuration is required for the application.

func GetAPINamespaces

func GetAPINamespaces() []string

GetAPINamespaces returns the all the available JSON-RPC API namespaces.

func GetDefaultAPINamespaces

func GetDefaultAPINamespaces() []string

GetDefaultAPINamespaces returns the default list of JSON-RPC namespaces that should be enabled

Types

type Config

type Config struct {
	config.Config

	EVM     EVMConfig     `mapstructure:"evm"`
	JSONRPC JSONRPCConfig `mapstructure:"json-rpc"`
	TLS     TLSConfig     `mapstructure:"tls"`
}

Config defines the server's top level configuration. It includes the default app config from the SDK as well as the EVM configuration to enable the JSON-RPC APIs.

func DefaultConfig

func DefaultConfig() *Config

DefaultConfig returns server's default configuration.

func GetConfig

func GetConfig(v *viper.Viper) Config

GetConfig returns a fully parsed Config object.

func ParseConfig

func ParseConfig(v *viper.Viper) (*Config, error)

ParseConfig retrieves the default environment configuration for the application.

func (Config) ValidateBasic

func (c Config) ValidateBasic() error

ValidateBasic returns an error any of the application configuration fields are invalid

type EVMConfig

type EVMConfig struct {
	// Tracer defines vm.Tracer type that the EVM will use if the node is run in
	// trace mode. Default: 'json'.
	Tracer string `mapstructure:"tracer"`
	// MaxTxGasWanted defines the gas wanted for each eth tx returned in ante handler in check tx mode.
	MaxTxGasWanted uint64 `mapstructure:"max-tx-gas-wanted"`
}

EVMConfig defines the application configuration values for the EVM.

func DefaultEVMConfig

func DefaultEVMConfig() *EVMConfig

DefaultEVMConfig returns the default EVM configuration

func (EVMConfig) Validate

func (c EVMConfig) Validate() error

Validate returns an error if the tracer type is invalid.

type JSONRPCConfig

type JSONRPCConfig struct {
	// API defines a list of JSON-RPC namespaces that should be enabled
	API []string `mapstructure:"api"`
	// Address defines the HTTP server to listen on
	Address string `mapstructure:"address"`
	// WsAddress defines the WebSocket server to listen on
	WsAddress string `mapstructure:"ws-address"`
	// GasCap is the global gas cap for eth-call variants.
	GasCap uint64 `mapstructure:"gas-cap"`
	// EVMTimeout is the global timeout for eth-call.
	EVMTimeout time.Duration `mapstructure:"evm-timeout"`
	// TxFeeCap is the global tx-fee cap for send transaction
	TxFeeCap float64 `mapstructure:"txfee-cap"`
	// FilterCap is the global cap for total number of filters that can be created.
	FilterCap int32 `mapstructure:"filter-cap"`
	// FeeHistoryCap is the global cap for total number of blocks that can be fetched
	FeeHistoryCap int32 `mapstructure:"feehistory-cap"`
	// Enable defines if the EVM RPC server should be enabled.
	Enable bool `mapstructure:"enable"`
	// LogsCap defines the max number of results can be returned from single `eth_getLogs` query.
	LogsCap int32 `mapstructure:"logs-cap"`
	// BlockRangeCap defines the max block range allowed for `eth_getLogs` query.
	BlockRangeCap int32 `mapstructure:"block-range-cap"`
	// HTTPTimeout is the read/write timeout of http json-rpc server.
	HTTPTimeout time.Duration `mapstructure:"http-timeout"`
	// HTTPIdleTimeout is the idle timeout of http json-rpc server.
	HTTPIdleTimeout time.Duration `mapstructure:"http-idle-timeout"`
}

JSONRPCConfig defines configuration for the EVM RPC server.

func DefaultJSONRPCConfig

func DefaultJSONRPCConfig() *JSONRPCConfig

DefaultJSONRPCConfig returns an EVM config with the JSON-RPC API enabled by default

func (JSONRPCConfig) Validate

func (c JSONRPCConfig) Validate() error

Validate returns an error if the JSON-RPC configuration fields are invalid.

type TLSConfig

type TLSConfig struct {
	// CertificatePath the file path for the certificate .pem file
	CertificatePath string `mapstructure:"certificate-path"`
	// KeyPath the file path for the key .pem file
	KeyPath string `mapstructure:"key-path"`
}

TLSConfig defines the certificate and matching private key for the server.

func DefaultTLSConfig

func DefaultTLSConfig() *TLSConfig

DefaultTLSConfig returns the default TLS configuration

func (TLSConfig) Validate

func (c TLSConfig) Validate() error

Validate returns an error if the TLS certificate and key file extensions are invalid.
