I agree with this.

Imagine a client that can connect to Ethereum wallets so people can pass tokens around. They would still have to pay the transfer fees, paying in ETH, but it would integrate that entire ecosystem into the existing Nostr social network. It might be a bit confusing for people to try and zap across that barrier, but that would just encourage the development of ways to zap across the blockchain networks. Maybe WBTC?

We don't want to completely restrict Nostr to Bitcoin Only, because we want to focus on adoption first.
