Functions

func DeployContract 

func DeployContract(ctx sdk.Context,
	evmKeeper types.EVMKeeper, feemarketKeeper types.FeeMarketKeeper,
	address common.Address, signer keyring.Signer,
	name, symbol string, decimals uint8) (common.Address, error)

func DeployERC20Contract 

func DeployERC20Contract(
	ctx sdk.Context,
	k Keeper,

Types

type Hooks 

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

Hooks wrapper struct for erc20 keeper

func (Hooks) PostTxProcessing 

func (h Hooks) PostTxProcessing(
	ctx sdk.Context,
	msg core.Message,
	receipt *ethtypes.Receipt,
) error

PostTxProcessing implements EvmHooks.PostTxProcessing. The EVM hooks allows users to convert ERC20s to Cosmos Coins by sending an Ethereum tx transfer to the module account address. This hook applies to both token pairs that have been registered through a native Cosmos coin or an ERC20 token. If token pair has been registered with:

  • coin -> burn tokens and transfer escrowed coins on module to sender
  • token -> escrow tokens on module account and mint & transfer coins to sender

Note that the PostTxProcessing hook is only called by sending an EVM transaction that triggers `ApplyTransaction`. A cosmos tx with a `ConvertERC20` msg does not trigger the hook as it only calls `ApplyMessage`.
