Cross-chain Token Transfers: MVP

[sonam-jo]

MVP Goals

Allow users to send tranche tokens

• from Centrifuge to other EVM chains
• from other EVM chains to Centrifuge

UI Changes

On the Portfolio tab

• Adding a Send button to tranche tokens (right now only have invest and redeem)
• Adding a Destination dropdown of which chain to pick (including what the user is on already) for tranche tokens sending actions
• ONLY display holdings from the network a user is connected to

Technical implementation

ON Centrifuge Chain

• IF destination == CentrifugeChain → call tokens.transfer(..)
• IF destination == EVM Chain → call liquidityPools.transferTrancheTokens(..)
• IF destination == Polkadot Parachain → NOT POSSIBLE!

ON EVM Chains

• IF destination == current EVM Chain → call erc20.transfer(..)
• IF destination == CentrifugeChain || other EVM Chain → call centrifugeRouter.transferTrancheTokens(..) NOTE: For this, best to do this after 2331 is done, and use CentrifugeRouter.transferTrancheTokens. That way gas is also automatically paid.

@onnovisser what's the best way to QA this ticket?
