* Request: Ask device for Ethereum address corresponding to address_n path @start @next EthereumAddress @next Failure

• repeated uint32 address_n = 1

  BIP-32 path to derive the key from master node

• optional bool show_display = 2

  optionally show on display before sending the result

* Request: Ask device for public key corresponding to address_n path @start @next EthereumPublicKey @next Failure

• repeated uint32 address_n = 1

  BIP-32 path to derive the key from master node

• optional bool show_display = 2

  optionally show on display before sending the result

* Response: Signed message @end

• optional bytes addressBin = 1

  address used to sign the message (20 bytes, legacy firmware)

• optional bytes signature = 2

  signature of the message

• optional string addressHex = 3

  address used to sign the message (hex string, newer firmware)

* Response: Contains public key derived from device private seed @end

• optional common.HDNodeType node = 1

  BIP32 public node

• optional string xpub = 2

  serialized form of public node

* Request: Ask device to sign message @start @next EthereumMessageSignature @next Failure

• repeated uint32 address_n = 1

  BIP-32 path to derive the key from master node

• optional bytes message = 2

  message to be signed

* Request: Ask device to sign transaction All fields are optional from the protocol's point of view. Each field defaults to value `0` if missing. Note: the first at most 1024 bytes of data MUST be transmitted as part of this message. @start @next EthereumTxRequest @next Failure

• repeated uint32 address_n = 1

  BIP-32 path to derive the key from master node

• optional bytes nonce = 2

  <=256 bit unsigned big endian

• optional bytes gas_price = 3

  <=256 bit unsigned big endian (in wei)

• optional bytes gas_limit = 4

  <=256 bit unsigned big endian

• optional bytes toBin = 5

  recipient address (20 bytes, legacy firmware)

• optional string toHex = 11

  recipient address (hex string, newer firmware)

• optional bytes value = 6

  <=256 bit unsigned big endian (in wei)

• optional bytes data_initial_chunk = 7

  The initial data chunk (<= 1024 bytes)
