I thought “1:1 conversion” meant there was literally nothing left to think about. Then I found the 9th decimal place.
When I first read that eligible stocks can be converted into corresponding bStocks at a 1:1 ratio with no conversion fee, the mechanism sounded completely straightforward to me.
But there is a tiny technical detail I almost missed.
Binance records equity positions with precision of up to 9 decimal places, while bStocks support up to 8 decimal places.
So imagine my stock position contains a fraction that extends all the way to the ninth decimal place. When that position is converted into a bStock, the part beyond the supported 8-decimal precision simply cannot be represented by the token.
Binance describes this residual amount as a rounding difference, not a conversion fee.
Financially, we're talking about an extremely small fraction. But conceptually, I found it surprisingly interesting.
Tokenization sounds like a simple transformation: take an asset and represent it on-chain. In reality, the traditional system and the token standard don't necessarily represent numbers with exactly the same precision.
That means even a 1:1 conversion still needs rules for what happens at the smallest possible fraction.
It made me realize that some of the most interesting parts of tokenization aren't the headline features like 24/7 trading.
They're the tiny edge cases that only appear when two different financial infrastructures have to agree on exactly what a number means.
Now whenever I see “1:1”, I know there is one more question worth asking:
1:1 — to what precision?
