XRP Ledger discloses overflow bug that could have minted XRP beyond its supply cap
XRP Ledger disclosed a software flaw in its payment engine that could have let someone create spendable XRP outside the intended supply cap. The issue was reported across October 9 and Friday coverage, and one report says the fix was released in xrpld 3.4.1 after testing showed unauthorized XRP creation. Another report says RippleX found no sign the flaw was used.
What this rests on
What it means
Each sentence links inside to the piece that supports it.
Users and holders of XRP notice that the ledger’s supply control was put under scrutiny, because the disclosed flaw concerned the creation of spendable XRP. That matters today because the issue was not just theoretical: researchers demonstrated unauthorized XRP creation in testing, and the patched version is now xrpld 3.4.1.
In practice, the change is that the payment-engine vulnerability has been patched, while the supply cap itself is still described as 100 billion XRP. What remains the same is the ledger’s capped design, but the disclosed bug showed that the software layer around it needed a fix before the limit could be relied on in operation.
Market reaction
The move was larger before the first headline than after. That is an observation, not an explanation: the market also moves on things nobody publishes.
How the story was built
Every piece in order, with the time its news medium declares — if it is not believable we use ours and say so — and what it added to what was already known at that point. Arriving first is not the same as adding something.
