Why a read-only portfolio tracker is the right trust model.
Updated: 5 June 2026
Many investors only want visibility. They do not want a portfolio app to place trades, move funds, hold custody, or request wallet private keys. That is where a read-only portfolio tracker becomes the better design.
What read-only means in practice
- No trade execution
- No fund transfers
- No transaction signing
- No private wallet keys or seed phrases
- No need for brokerage passwords when a read-only workflow is enough
Why investors care
Trust is often the hardest part of adopting a new finance product. A read-only portfolio tracker narrows the risk surface and makes the product easier to understand: it can observe the portfolio, but it cannot act on it.
What a read-only tracker still needs to do well
Read-only does not mean shallow. Serious investors still want holdings, transactions, fees, FX, cost basis, cash, and explainable performance. The trust model changes the permissions, not the depth of analysis.
