Feature/sequence wallet

[SamueleA]

Description

This features is an integration of the Sequence wallet The wallet can be accessed either as a chrome extension or through the SDK. The former integration is done through the injected wallet package and the latter through the Sequence package. If window.ethereum.isSequence is not true, the connection through the SDK will be made available since this will mean that the user does not have the chrome extension.

Notes:

• signing message is not working on the demo app due to lack of support for EIP-1271 since Sequence uses a contract wallet. The sequence SDK provider a method sequence.utils.isValidMessageSignature which allows the signature to be verified,
• switching to a network whose contract wallet is undeployed doesn't work sometimes/has a weird flow. This is a known issue which will be fixed on Sequence's side

Hey @SamueleA I am taking a look at this at the moment.

switching to a network whose contract wallet is undeployed doesn't work sometimes/has a weird flow. This is a known issue which will be fixed on Sequence's side

The wallet seems to default to Polygon, should I be able to switch to Ethereum mainnet, or does come under the known issue that you mention above? I see the wallet trigger a popup, but it sits there for a bit with a blank screen and then goes away without switching to Ethereum mainnet.

Yes, that is indeed the known issue I have mentioned. The Mainnet wallet is not deployed by default, just the polygon one. So the expected behavior when switching to Mainnet would have been a flow for that scenario within the popup. Instead, the popup just closes
