Yes, that's one thing, collateral. And I saw some DeFi projects focused on privacy of their users so DeepOnion could co-operate. Moreover, there could be finally some usecase for DeepVault, it is a decentralized notary service so it could be integrated into some DeFi project. These projects will offer more and more decentralized services, not only lending and exchanges, but also e.g. insurance so they might be interested in notary services as something additional as their competition advantage.
But currently there might be a technical problem, because DeFi projects usually work with ERC-20 tokens. I believe it will change in the future, but it might take some time. However, it might be possible to create ERC-20 compatible wrapped ONION as there is already e.g. wrapped BTC.
So the Team should definitely explore this area more as it might be a great opportunity. Of course, it can turn out that there are no significant benefits, but it is worth trying.
Wrapped ONION would be a good idea WONION
In the future can bring benefits when interacting with ERC20 tokens and for using ONION as colateral in Defi platforms.
Also Chainlink is another good project that will function as a bridge between current non blockchain companies willing to connect their commercial software to a blockchain project. So they might connect to ONION so their users can have private tx.
