I’d like to be able to find a way to trust that someone has control of an address across multiple chains. An identity token seems to be the sane way to do that in a unified manner- possibly via ENS.
Let’s say I want to reward someone for doing something with their Bitcoin by giving them access to something on Ethereum. Example: They “login with Ethereum”/connect their wallet with an ENS token in it- I look at their Bitcoin address, see they transferred Bitcoin to a specific wallet, and now I want to allow them to mint an NFT on Ethereum. If I could verify that they are in fact in control of their bitcoin address, and their Ethereum address, I could do something like this.
You “prove” ownership of your wallet with the ENS token simply by being able to sign, but anyone can put any Bitcoin address or Solana address in their text records- so we can’t trust that they actually control them.
Anyway, just thought I’d bounce it off people here to see if anyone else sees value in “verified” cross chain addresses, etc. Or please let me know if there is some other way initiative to do this.
