# Client
|
||
|
||
A user can query and interact with the `evm` module using the CLI, JSON-RPC, gRPC or REST.
|
||
|
||
## CLI
|
||
|
||
Find below a list of `ethermintd` commands added with the `x/evm` module. You can obtain the full list by using the `ethermintd -h` command.
|
||
|
||
### Queries
|
||
|
||
The `query` commands allow users to query `evm` state.
|
||
|
||
**`code`**
|
||
|
||
Allows users to query the smart contract code at a given address.
|
||
|
||
```go
|
||
ethermintd query evm code [address] [flags]
|
||
```
|
||
|
||
```bash
|
||
# Example
|
||
$ ethermintd query evm code 0x7bf7b17da59880d9bcca24915679668db75f9397
|
||
|
||
# Output
|
||
code: "0xef616c92f3cfc9e92dc270d6acff9cea213cecc7020a76ee4395af09bdceb4837a1ebdb5735e11e7d3adb6104e0c3ac55180b4ddf5e54d022cc5e8837f6a4f971b"
|
||
```
|
||
|
||
**`storage`**
|
||
|
||
Allows users to query storage for an account with a given key and height.
|
||
|
||
```bash
|
||
ethermintd query evm storage [address] [key] [flags]
|
||
```
|
||
|
||
```bash
|
||
# Example
|
||
$ ethermintd query evm storage 0x0f54f47bf9b8e317b214ccd6a7c3e38b893cd7f0 0 --height 0
|
||
|
||
# Output
|
||
value: "0x0000000000000000000000000000000000000000000000000000000000000000"
|
||
```
|
||
|
||
### Transactions
|
||
|
||
The `tx` commands allow users to interact with the `evm` module.
|
||
|
||
**`raw`**
|
||
|
||
Allows users to build cosmos transactions from raw ethereum transaction.
|
||
|
||
```bash
|
||
ethermintd tx evm raw [tx-hex] [flags]
|
||
```
|
||
|
||
```bash
|
||
# Example
|
||
$ ethermintd tx evm raw 0xf9ff74c86aefeb5f6019d77280bbb44fb695b4d45cfe97e6eed7acd62905f4a85034d5c68ed25a2e7a8eeb9baf1b84
|
||
|
||
# Output
|
||
value: "0x0000000000000000000000000000000000000000000000000000000000000000"
|
||
```
