Support for other backend languages

If your backend services are written in a language other than JS or Go, you can still easily integrate Sequence, as Sequence is really just a standard Ethereum client library with some extra features. In many cases, the extra features are best utilized on the client-side / dapp. If your situation for example is a Python or Java backend where you’d like to verify signatures from a Sequence Wallet, well then, you can call the standard EIP1271 function for the account address from your backend. If you’d like to use the Sequence’s Meta-Transaction capabilities, see Building Relaying Server with Sequence.
