[META] XCM Cookbook Asset Guides #4377

Open liamaharon opened 4 months ago

liamaharon commented 4 months ago

An excellent new 'Guides' section was added to the Polkadot SDK docs in https://github.com/paritytech/polkadot-sdk/pull/2633.

We should collect a list of common XCM messages related to Asset movement and management in this issue, and work on adding guides for them.

Best way to build the list would be looking at existing XCM use cases, and also surveying the ecosystem.

I think we need to support the most common cross project use cases that DeFi supports today:

Supply liquidity into an AMM
Execute a trade in an AMM
Deposit collateral into a lending market
Borrow collateral in a lending market
Wrap a token to receive a different token

I would look at intents and Uniswap X to see how users sign trade messages today in EVM and I would look at:

EIP 4626 Tokenized Vault Standard
EIP 7540 Asynchronous tokenzied vault standard

Ideally we can create XCM messages with a similar structure.
