## Signatures
Ethermint supports [EIP-155](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-155.md)
signatures. However, just as in Cosmos, Ethermint will support multiple signers.
A client is expected to sign the `Transaction` just as in Ethereum, however, the
`EmbeddedTx` contains a canonical signature structure that itself contains the
signature and other information such as an account's sequence number. The sequence
number is expected to increment every time a message is signed by a given account.
This prevents "replay attacks", where the same message could be executed over and
over again.
signatures. A `Transaction` is expected to have a single signature for Ethereum
routed transactions. However, just as in Cosmos, Ethermint will support multiple
signers for `EmbeddedTx` Cosmos routed transactions. Signatures over the
`Transaction` type are identical to Ethereum. However, the `EmbeddedTx` contains
a canonical signature structure that contains the signature itself and other
information such as an account's sequence number. The sequence number is expected
to increment every time a message is signed by a given account. This, in addition
to the chain ID, prevents "replay attacks", where the same message could be
executed over and over again.
An `EmbeddedTx` list of signatures must much the unique list of addresses returned by
each message's `GetSigners` call. In addition, the address of first signer of the
`EmbeddedTx` is responsible for paying the fees and must also match the address of
the signer of the embedding `Transaction`. As such, there will be one duplicate
signature.
