Types

type DefaultRequestInterceptor

type DefaultRequestInterceptor struct {
	// contains filtered or unexported fields
}

func NewDefaultRequestInterceptor

func NewDefaultRequestInterceptor(
	beRpcBackend berpcbackend.BackendI,
	backend EvmBackendI,
) *DefaultRequestInterceptor

func (*DefaultRequestInterceptor) GetAccount

func (m *DefaultRequestInterceptor) GetAccount(accountAddressStr string) (intercepted, append bool, response berpctypes.GenericBackendResponse, err error)

GetAccount returns the contract information if the account is a contract. Other-wise no-op.

func (*DefaultRequestInterceptor) GetDenomsInformation

func (m *DefaultRequestInterceptor) GetDenomsInformation() (intercepted, append bool, denoms map[string]string, err error)

func (*DefaultRequestInterceptor) GetModuleParams

func (m *DefaultRequestInterceptor) GetModuleParams(moduleName string) (intercepted bool, res berpctypes.GenericBackendResponse, err error)

func (*DefaultRequestInterceptor) GetTransactionByHash

func (m *DefaultRequestInterceptor) GetTransactionByHash(hashStr string) (intercepted bool, response berpctypes.GenericBackendResponse, err error)

type EvmBackend

type EvmBackend struct {
	// contains filtered or unexported fields
}

EvmBackend implements the EvmBackendI interface

func NewEvmBackend

func NewEvmBackend(
	ctx *server.Context,
	logger log.Logger,
	clientCtx client.Context,
	externalServices berpctypes.ExternalServices,
) *EvmBackend

NewEvmBackend creates a new EvmBackend instance for EVM Block Explorer

func (*EvmBackend) EvmCall

func (m *EvmBackend) EvmCall(input string, contract common.Address, optionalChainId *hexutil.Big, optionalBlockNumber *hexutil.Uint64, optionalGas uint64) ([]byte, error)

func (*EvmBackend) GetBankDenomsMetadata

func (m *EvmBackend) GetBankDenomsMetadata(coins sdk.Coins) map[string]banktypes.Metadata

func (*EvmBackend) GetContractCode

func (m *EvmBackend) GetContractCode(contractAddress common.Address) ([]byte, error)

func (*EvmBackend) GetErc20Balance

func (m *EvmBackend) GetErc20Balance(accountAddress common.Address, contractAddresses []common.Address) (berpctypes.GenericBackendResponse, error)

func (*EvmBackend) GetErc20ContractInfo

func (m *EvmBackend) GetErc20ContractInfo(contractAddress common.Address) (berpctypes.GenericBackendResponse, error)

GetErc20ContractInfo will return information of ERC20 contract by address.

• name (optional): the name of the ERC20 token.
• symbol (mandatory): the symbol of the ERC20 token.
• decimals (mandatory): the number of decimals the token uses.

If failed to query any of the mandatory fields, it will return an error. If failed to query the optional field, it will continue.
