Functions

func CreateEIP712CosmosTx 

func CreateEIP712CosmosTx(
	ctx sdk.Context,
	appEvmos *app.Evmos,
	args EIP712TxArgs,
) (sdk.Tx, error)

CreateEIP712CosmosTx creates a cosmos tx for typed data according to EIP712. Also, signs the tx with the provided messages and private key. It returns the signed transaction and an error

func CreateEthTx 

func CreateEthTx(
	ctx sdk.Context,
	appEvmos *app.Evmos,
	privKey cryptotypes.PrivKey,
	from sdk.AccAddress,
	dest sdk.AccAddress,
	amount *big.Int,
	nonceIncrement int,
) (*evmtypes.MsgEthereumTx, error)

CreateEthTx is a helper function to create and sign an Ethereum transaction.

If the given private key is not nil, it will be used to sign the transaction.

It offers the ability to increment the nonce by a given amount in case one wants to set up multiple transactions that are supposed to be executed one after another. Should this not be the case, just pass in zero.

func GasLimit 

func GasLimit(ctx sdk.Context, from common.Address, data evmtypes.HexString, queryClientEvm evmtypes.QueryClient) (uint64, error)

GasLimit estimates the gas limit for the provided parameters. To achieve this, need to provide the corresponding QueryClient to call the `eth_estimateGas` rpc method. If not provided, returns a default value

func GenerateAddress 

func GenerateAddress() common.Address

GenerateAddress generates an Ethereum address.

func NewAccAddressAndKey 

func NewAccAddressAndKey() (sdk.AccAddress, *ethsecp256k1.PrivKey)

NewAccAddressAndKey generates a private key and its corresponding Cosmos SDK address.

func NewAddrKey 

func NewAddrKey() (common.Address, *ethsecp256k1.PrivKey)

NewAddrKey generates an Ethereum address and its corresponding private key.

func NewSigner 

func NewSigner(sk cryptotypes.PrivKey) keyring.Signer

func PrepareCosmosTx 

func PrepareCosmosTx(
	ctx sdk.Context,
	appEvmos *app.Evmos,
	args CosmosTxArgs,
) (authsigning.Tx, error)

PrepareCosmosTx creates a cosmos tx and signs it with the provided messages and private key. It returns the signed transaction and an error

func PrepareEIP712CosmosTx 

func PrepareEIP712CosmosTx(
	ctx sdk.Context,
	appEvmos *app.Evmos,
	args EIP712TxArgs,
) (client.TxBuilder, error)

PrepareEIP712CosmosTx creates a cosmos tx for typed data according to EIP712. Also, signs the tx with the provided messages and private key. It returns the tx builder with the signed transaction and an error

func PrepareEthTx 

func PrepareEthTx(
	txCfg client.TxConfig,
	appEvmos *app.Evmos,
	priv cryptotypes.PrivKey,
	msgs ...sdk.Msg,
) (authsigning.Tx, error)

PrepareEthTx creates an ethereum tx and signs it with the provided messages and private key. It returns the signed transaction and an error

Types

type CosmosTxArgs 

type CosmosTxArgs struct {
	// TxCfg is the client transaction config
	TxCfg client.TxConfig
	// Priv is the private key that will be used to sign the tx
	Priv cryptotypes.PrivKey
	// ChainID is the chain's id on cosmos format, e.g. 'evmos_9000-1'
	ChainID string
	// Gas to be used on the tx
	Gas uint64
	// GasPrice to use on tx
	GasPrice *sdkmath.Int
	// Fees is the fee to be used on the tx (amount and denom)
	Fees sdk.Coins
	// FeeGranter is the account address of the fee granter
	FeeGranter sdk.AccAddress
	// Msgs slice of messages to include on the tx
	Msgs []sdk.Msg
}

CosmosTxArgs contains the params to create a cosmos tx

type EIP712TxArgs 

type EIP712TxArgs struct {
	CosmosTxArgs       CosmosTxArgs
	UseLegacyExtension bool
	UseLegacyTypedData bool
}

type InvalidTx 

type InvalidTx struct{}

InvalidTx defines a type, which satisfies the sdk.Tx interface, but holds no valid transaction information.

NOTE: This is used for testing purposes, to serve the edge case of invalid data being passed to functions.

func (InvalidTx) GetMsgs 

func (InvalidTx) GetMsgs() []sdk.Msg

func (InvalidTx) ValidateBasic 

func (InvalidTx) ValidateBasic() error

type Signer 

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

Signer defines a type that is used on testing for signing MsgEthereumTx

func (Signer) Sign 

func (s Signer) Sign(_ string, msg []byte) ([]byte, cryptotypes.PubKey, error)

Sign signs the message using the underlying private key

func (Signer) SignByAddress 

func (s Signer) SignByAddress(address sdk.Address, msg []byte) ([]byte, cryptotypes.PubKey, error)

SignByAddress sign byte messages with a user key providing the address.
