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.

ethermintd query evm code [address] [flags]

# Example
$ ethermintd query evm code 0x7bf7b17da59880d9bcca24915679668db75f9397

# Output
code: "0xef616c92f3cfc9e92dc270d6acff9cea213cecc7020a76ee4395af09bdceb4837a1ebdb5735e11e7d3adb6104e0c3ac55180b4ddf5e54d022cc5e8837f6a4f971b"

storage

Allows users to query storage for an account with a given key and height.

ethermintd query evm storage [address] [key] [flags]

# 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.

ethermintd tx evm raw [tx-hex] [flags]

# Example
$ ethermintd tx evm raw 0xf9ff74c86aefeb5f6019d77280bbb44fb695b4d45cfe97e6eed7acd62905f4a85034d5c68ed25a2e7a8eeb9baf1b84
