ERC-7683 – Cross-Chains intents: Questions & discussion

Hi!

I'm just curious about how this ERC-7683 actually works / will work.

My understanding is based on the following: – ERC-7683: Unifying Ethereum With Cross-Chain Intents – erc7683.org

Who will run the third-party fillers/solvers, who are supposed to execute cross-chain actions on behalf of the end user?
