Acceptance criteria

• Update the Vortex flow such that it starts the off-ramp from the above listed networks
• Subsidy feature takes into account liquidity on the respective network
• Network dropdown allows user to choose network to off-ramp from
• Network selection creates a prompt for the user to change network in the wallet
• Asset list is specific to the network chosen
• Progress screen shows accurate asset and network
• Deep links for 'To' and 'From' assets should also include the network selection
• Compare fee should consider accurate asset / network
• Changing network between EVM chains should not disconnect wallet considering wallet is connected

Note

• Assumption: This ticket is for both frontend and backend changes, assuming configuration changes to the current setup

@pendulum-chain/devs What all things to be considered when adding support to the above listed networks and assets?

[TorstenStueber]

@pendulum-chain/devs how can we check/ensure that Squid router supports all these network/asset pairs?

[ebma]

I would again just check for routes of all the listed tokens in the squidrouter app/UI.

For example, when selecting to bridge USDC from Ethereum to Moonbeam here, the app shows a route so we know that we can use this or a similar route in vortex. We then need to check this for all tokens and if every single one of them has a route it should be possible to add all of them with little effort.

[TorstenStueber]

I checked them in the UI, for all five networks USDC and USDT are available, so we should be good to go.

@TorstenStueber anything else to be considered before moving this ticket to ready like subsidy or anything else?

[TorstenStueber]

No, we might only first merge the Asset Hub tickets so that the wallet switch code will be more clear to implement.
