Not every token is as simple as “send 100, receive 100.”
Some tokens take a percentage from transfers automatically.
These are commonly known as tax tokens or fee-on-transfer tokens.
The interesting part is that the tax isn't the same thing as a normal network fee or DEX fee.
It is part of the token's own transfer logic.
That distinction matters.
Imagine you want to swap an asset and the interface estimates a certain amount for you.
If the token removes a percentage during the transfer, the amount that actually arrives can be different from what the route expected.
Now the problem isn't just the token.
It can affect the entire execution path.
STON.fi has built safeguards around this category because its routing infrastructure can involve multiple DEXs and multiple steps.
A taxable token can create unpredictable delivery amounts, increase execution uncertainty and cause problems when it appears in the middle of a route.
STON.fi therefore treats these assets differently.
Taxable tokens cannot be used as intermediate assets in routes, and tokens with transfer taxes above 10% aren't supported by the STON.fi dApp for technical reasons.
This is an important part of DeFi infrastructure that doesn't get enough attention.
A good swap experience isn't only about finding liquidity or getting a competitive price.
It also depends on whether the assets involved behave predictably.
The more complex DeFi becomes, the more important these safeguards become.
Because users shouldn't have to discover how a token works only after they've already clicked swap.
