The XRP Ledger has faced a major security concern after developers found a software flaw that could have allowed attackers to create trillions of XRP without the proper funds. The issue raised serious questions about the safety of the network and the rules that protect its token supply.
On September 25, 2026, developers released an emergency software update to fix the flaw. They chose this quick route instead of the usual process, which requires support from trusted network validators over two consecutive weeks. On October 12, developers defended that choice after criticism from parts of the crypto community.
The bug had the potential to weaken one of XRP’s key features: its fixed supply. At the launch of the XRP Ledger in 2012, the total supply was set at 100 billion XRP. The flaw could have allowed an attacker to bypass this limit under a special set of conditions.
However, there is an important point to note. Reports state that no evidence showed that anyone had used the flaw to create unauthorized XRP on a public network. The emergency fix aimed to prevent a possible attack before it could cause harm.
What Is the XRP Ledger?
The XRP Ledger, also known as XRPL, is a public blockchain. It allows users to send and receive digital assets, make payments, and trade tokens. XRP is the network’s native digital asset.
A blockchain records transactions on a shared digital ledger. Network participants use software to check transactions and agree on the valid state of that ledger. This system helps users transfer assets without the need for one central company to approve every payment.
The XRP Ledger also has a built-in exchange. Users can place offers to trade one asset for another through the network. The software must calculate the value of these offers correctly so that each party receives the proper amount.
This process depends on accurate code. Even a small error in a calculation can create a serious risk if the software fails to check the result. In this case, a flaw in the payment engine could have allowed a specially designed transaction to bypass the normal rules for XRP supply.
How the Critical Bug Worked
The flaw was related to an integer overflow in the XRP Ledger’s payment engine. In simple terms, an integer overflow occurs when a number exceeds the limit that a computer system can store correctly.
The software may then return a much smaller number instead of the correct total. If the code does not detect this error, it can produce a result that makes no sense.
The XRP Ledger used calculations to process certain trades and payments. Researchers found that an attacker could have set up hundreds of unusual offers that asked for very large amounts of XRP in exchange for tiny amounts of another asset.
The attacker could then have used one carefully prepared payment to take all those offers at once. Due to the calculation error, the sellers could have received the full amounts shown in their offers, while the buyer paid far less than the true total.
This would have created a gap between the amount of XRP paid and the amount of XRP received by the sellers. Under the right conditions, the flaw could have allowed new, spendable XRP to appear without the normal supply checks to stop it.
The attack was not a simple trick that anyone could trigger through an ordinary payment. It required a carefully designed set of offers and a transaction built to exploit the software error. Even so, the possible damage was severe enough to demand urgent action.
The Bug Could Have Created 18.45 Trillion XRP
One of the most serious details in the reports was the possible scale of the attack. Researchers said a single exploit transaction could have created about 18.45 trillion XRP.
The original XRP supply was set at 100 billion tokens. The possible amount from the exploit was therefore about 184 times the original supply.
Such a result would have challenged the supply limit that forms a key part of XRP’s design. If an attacker had created and sold a large amount of unauthorized XRP, it could have caused major losses for traders and other asset holders.
A sudden increase in supply could also have damaged trust in the network. People who hold XRP rely on the rules that govern its supply and use. If those rules could be bypassed, users might question whether the ledger could protect their assets.
Still, the figure of 18.45 trillion XRP refers to the theoretical scale of the exploit, not to tokens that were actually created. Reports state that researchers found no evidence of such an attack on a public network. The figure shows why developers treated the flaw as a serious threat.
A Decade-Old Flaw Comes to Light
Reports state that the vulnerable code dated back to 2015. This means the issue may have remained in the XRP Ledger’s software for about 11 years before researchers found it.
The discovery shows that even well-established blockchain projects can have serious software flaws. A network may process millions of valid transactions and still contain an error that remains hidden until a researcher tests an unusual case.
The flaw came to light through work by Veria Labs, a security firm that uses artificial intelligence tools to help find software weaknesses. The firm’s researchers reported the issue on September 22, 2026.
The discovery also highlights the value of independent security research. Developers who write and maintain software cannot always predict every possible way an attacker might use it. Outside researchers can test unusual cases and help teams find problems before criminals exploit them.
According to reports, RippleX, the development arm of Ripple, confirmed the issue and prepared a fix. The emergency update, known as xrpld version 3.4.1, was released on September 25, three days after the report.
Why Developers Skipped the Usual Vote
The XRP Ledger normally uses an amendment process for changes to its transaction rules. Under this system, a proposed change must receive support from more than 80% of trusted validators for two consecutive weeks before it becomes active.
This process gives network participants time to review a change and helps the network move to new rules in a coordinated way. It also supports the idea that no single party should have full control over the ledger.
However, developers said that the usual process was too slow for this particular security issue. If they had made the full fix public while the old rules remained active for two weeks, attackers might have had time to study the code and work out how to exploit the weakness.
The team therefore chose an emergency release. The patch took effect on each server as soon as its operator installed the updated software. This allowed operators to protect their systems without a wait for the normal amendment period.
The decision was unusual. Reports describe it as the first deliberate bypass of the standard amendment process since that system began more than ten years ago. Developers argued that the risk of a delay was greater than the risk of an emergency update.
Why the Emergency Fix Faced Criticism
Although the patch aimed to protect the network, the decision also led to concerns about decentralization.
A decentralized blockchain should not depend on one person or company to make every important decision. Instead, independent participants should have the ability to review changes and choose which software they run.
Critics questioned whether the emergency process gave too much influence to the XRP Ledger Foundation, RippleX, and core developers. They also raised concerns about the timing of the software release and the delay before the source code became public.
These questions matter because users need trust in both the security of a network and the process used to manage it.
The XRP Ledger Foundation defended the decision. It said the response came from joint work among the foundation, RippleX, core developers, and validators. It also stressed that no single party could force every network operator to install the update.
The foundation’s position was that coordination during a security emergency does not automatically mean that a network is centralized. Independent operators can share information and agree that a fast fix is necessary while they retain control over their own systems.
Did the Bug Create Any Unauthorized XRP?
The reports available on October 12 state that there was no evidence of unauthorized XRP creation on a public network.
This point is vital because the theoretical risk and the actual outcome are very different. Researchers showed how the flaw might have worked, but that does not mean an attacker used it successfully against the live network.
The XRP Ledger Foundation also addressed claims that new XRP might already exist outside the official supply. It said that XRP balances are public and that members of the community can check the ledger’s supply data.
The emergency patch was a preventive measure. Its purpose was to close the weakness before anyone could use it to break the supply rules.
Users should therefore avoid treating the figure of 18.45 trillion XRP as proof that the network created that amount. Reports describe a possible attack, not a confirmed loss or a real increase in supply.
What This Means for XRP Holders
For XRP holders, the incident is a reminder that the safety of a cryptocurrency depends on more than its price or market demand. The code that checks transactions and protects token supply is also essential.
The discovery may cause some users to ask whether their assets remain safe. Based on the reports, the vulnerability was addressed through the emergency release, and there was no evidence of a successful exploit on a public network.
Even so, users should pay attention to official software updates and security notices from the XRP Ledger project. Network operators have a direct role in keeping their systems up to date, while ordinary users should rely on trusted wallets and established security practices.
The incident also shows why open review and independent testing matter. A flaw can remain hidden for years, but a careful review can expose it before it causes serious damage.
For the wider crypto market, the episode may lead to more debate about the balance between fast security action and decentralized decision-making. Both goals matter. A network must respond quickly to serious threats, but it should also explain its choices clearly and preserve trust among its participants.
The Role of Artificial Intelligence in Crypto Security
The discovery has also drawn attention to the role of artificial intelligence in software security. Reports say Veria Labs used an AI agent to help find the flaw.
AI tools can help researchers test large amounts of code and identify unusual patterns that may point to a weakness. They may also help teams review old software that has been in use for many years.
However, these tools can help attackers as well. If AI makes it easier to find flaws, criminals may also use it to search for weaknesses in public software.
That creates a need for faster security checks, careful code review, and prompt software updates. Developers cannot assume that code is safe simply because it has worked for a long time.
RippleX engineers have said they plan to expand the use of AI-assisted bug searches and formal verification. Formal verification uses mathematical methods to check whether software follows specific rules. Such methods may help teams catch errors before a release reaches users.
Conclusion
The XRP Ledger’s emergency patch has brought an important security issue into focus. A flaw in its payment engine could have allowed a carefully designed transaction to create about 18.45 trillion XRP, far above the original supply of 100 billion tokens.
Developers released the fix on September 25, 2026, without the usual two-week validator vote. They argued that a delay could have exposed the weakness to attackers. The XRP Ledger Foundation later defended the decision amid concerns about decentralization and the way the patch reached network operators.
Reports state that there was no evidence of unauthorized XRP creation on a public network. The large figure refers to the possible result of an exploit, not to an event that actually took place.
The case offers a clear lesson for the crypto industry. Strong security needs regular code checks, fast action when serious flaws appear, and clear communication with the public. At the same time, emergency decisions must respect the role of independent network participants.
For XRP holders, the patch is a reminder to follow official security updates and to judge the network by both its technical safeguards and its response to problems. The flaw was serious, but the reported response aimed to close it before it could cause harm.
