Thorchain (https://thorchain.org/) is one of them but i assume a decent work would be reuired to upgrade nodes/decentralized custody on hive side, and then getting them help us integerate.

As hive might not bring them a lot of volume, so our case for them could be week, but if DAO provides intial liquity and promotion etc. they may take it.

Thorswap is one of app on thorchain: https://app.thorswap.finance/swap

That's why we are building @vsc.network to not only help solve the custody problem but also bring smart contracts to HIVE that allows any chain to easily integrate with HIVE via a smart contract. We can already do cross chain swaps using HTLC, with full Bitcoin to HIVE wrapping under heavy development. It's only a matter of time.

Seems like its much more complex than we think at first glance. There is a trust and liability issue when it comes to pool fund control and accumulation from what ive seen devs talk about.
Nothing that cant be solved but it would take a mind more familiar with the tech than mine to solve it.

Uniswap on ETH is always popular, now Thorchain is making waves as well with simplified pooling without wraps.
