Staking and gas tokens post warp

[minghinmatthewlam]

Following questions are all in the context of warp already being launched:

1. When subnets are created or transition into elastic subnets, how can they use erc20 tokens are the staking token? After the erc20 token gets created on the C chain:

• What features are needed to support the erc20 token being sent from C chain to the P chain to use as the staking token?
• Does warp play a part in the transfer of erc20 from C to P? If so, what would the payload of the warp message include i.e. contract address?

2. Will subnets be able to use erc20 tokens created on the C chain as their native tokens for paying gas fees? If so, at subnet creation how will the erc20 token be transferred from C chain to subnet, and set as the native fee token? Will there be a warp protocol involved?
3. For subnet staking, do validators only need to connect to a P chain rpc endpoint to stake with multiple subnets? Is it correct for Cosmos staking, you'd need to connect to individual zones?

Thanks

In 2022, a community member wrote a tutorial for the tutorials contest on how to use an ERC-20 as the gas token. Info may be out of date, but it goes through how to deploy a bridge and a relayer, and bridge a C-chain ERC-20 to a subnet.

At a quick glance it doesn't seem like the tutorial was actually finished, bc there is no info on how to actually use the token as the gas token.
