Testnet and Devnet for XRP Ledger developers will be reset on Nov 25, 5–6 PM PT.
All on-chain state (accounts, tokens, AMMs, etc.) will be deleted and need to be re-fund and re-setup afterward.

We welcome @FlareNetworks to the recommended XRP Ledger validator list published by the XRPL Foundation.
Flare aligns with the core values of the @XRP Ledger, is actively participating in governance, and contributes to the broader ecosystem.
The XRP Ledger is no longer experiencing those occasional slower ledger closes following the publication of the recommended xrpld configuration.
We are continuing to prepare a dot release for the community to address the behavior observed.
We've begun rolling out a recommended xrpld config change to hub, validator and node operators to address the issue for now.
In parallel, we're testing fixes for a point release that will address the root cause.
We'll continue updating the community as we progress.
This is still the case, and you may occasionally observe slower-than-usual ledger close times on the XRP Ledger.
Outside of this, closing times are normal.
We're aware of the issue and are finalizing a fix release targeting it as soon as possible.
Some ledger closings on the XRP Ledger are currently slower than usual, and ledgers can occasionally take longer to close. Outside of this closing times are normal.
We have been actively investigating this and working on a fix since earlier today.
We'll keep you updated!
Welcome, on @XRP !
XRP Ledger version 3.4.1 is now the minimum required version after the recent amendments were activated.
This release patched critical parts of the XRP Ledger.
The vulnerability report can be found here:
xrpl.org/blog/2026/vulnerabi…
Public release notes:
github.com/XRPLF/rippled/rel…
xrpld 3.4.1 is being released with a Batch fix and stability improvements.
We’re asking validators and node operators to upgrade as soon as possible. There has been no impact to mainnet, and no loss of funds.
There is also a new fix amendment, fixBatchV1_2, which addresses a minor issue with Batch that does not pose a risk to funds.
The amendment is marked as Default Yes. Both Batch and the fix amendment are in the activation period and set to activate in 2 weeks. A detailed technical report will be shared after the fix amendment has been activated.
XRP Ledger version 3.4.0 is now available ✅
New amendments for voting:
- Lending Protocol v1.1 - closed-ended vaults and cash-basis accounting.
- fix Cleanup - bundled fixes.
Performance and Stability:
- Online delete now pauses on ledger history gaps, so nodes stay closer to the tip.
- Peer protocol hardening and faster MPT freeze checks.
Packages have moved to packages.xrplf.org with an XRPLF signing key. Nodes on 3.3.0 or earlier must update their repo config.

Formal Verification for the XRP Ledger Lending Protocol.
The Lending Protocol (XLS-66) and Single Asset Vaults (XLS-65) are not smart contracts. They are native financial logic inside xrpld.
FV raises assurance above ordinary testing. Specify the behavior that must always hold, prove it in a machine-checked model, and keep that model aligned with the production code.
In depth thread why @CommonPrefix picked Lean 4 to perform FV on XRPL.

The Batch V1.1 amendment shipped in xrpld 3.3.0 and is now up for voting.
After the v1.0 signature bug was caught in February (pre-Mainnet, no funds at risk), we rebuilt it: root-cause fix, 4 senior reviewers, a Sherlock attackathon, and audits from Halborn and Common Prefix. We also fixed a few other bugs our new AI red-teaming efforts caught along the way.
What changed and why it's ready: dev.to/ripplexdev/batch-v11-…
Atomic transactions on the XRPL, no smart contracts needed. Try it on Devnet today.
Formal Verification is raising the bar for security in the blockchain space.
The XRP Ledger formal verification already led to increased security and protocol hardening.
Excited about the work with @RippleXDev on formally verifying the XRP Ledger. More on the technical details behind this effort. 🧵 1/6

The same technology that just let Claude formalize Fermat's Last Theorem is also being used to formally verify the XRP Ledger. We're working with @CommonPrefix to prove, mathematically, that XRPL's most critical parts do exactly what we expect them to do.
commonprefix.com/blog/formal…
Checking that a major mathematical proof is correct can take years. Formalization—converting the mathematical reasoning into a form computer proof assistants like Lean can verify—can help.
Last month, Claude completed the first formalized proof of Fermat’s Last Theorem, one of the most famous theorems of all time. This was a project experts thought would take many years. It is the largest Lean proof ever written.
Fermat’s Last Theorem was first proven in 1995 by Sir Andrew Wiles, more than 350 years after it was conjectured. Our proof, which totals over 13 million lines of code, provides machine verification. More importantly, it proves over 29,000 other theorems that the proof requires, across many areas of math which had never before been formalized.
We see this as a major step in the long process of firming up the core of mathematical knowledge, building on work from three centuries of mathematicians and hundreds of contributors to Lean and Mathlib. We are optimistic that AI-assisted verification of mathematical proofs will help reduce the burden of refereeing mathematics in an era where more proofs are being produced than ever before.

Permission Delegation on the XRP Ledger has passed an independent security review by @cantinasecurity and the XRPL quality assurance test suite.
All findings were fixed in v1.1 and verified by Cantina, and the QA team found no regressions across 5,088 tests.
