RippleX Prepares Major Update with Revamped Security Features
RippleX is gearing up to release xrpld version 3.3.0 the week of August 1, 2026, a significant update that includes five proposed amendments for validator consideration. Among these are rewritten versions of the Batch and Permission Delegation features, both of which were previously halted before mainnet activation due to critical authorization flaws identified by security researchers. No funds were lost as a result of these vulnerabilities. The upcoming release now hinges on whether the XRP Ledger ecosystem has sufficient trust in the revised implementations to achieve the required 80% validator approval threshold.
Batch Amendment: Addressing Signature Validation Flaws
The original Batch amendment contained a bug in its signature validation logic. This flaw could have allowed an attacker to execute internal transactions from any victim account without possessing the victim’s private keys. According to an official XRPL vulnerability disclosure, researcher Pranamya Keshkamat and Cantina AI’s autonomous audit tool Apex identified this issue on February 19, 2026, while the amendment was still undergoing the voting process. UNL validators were subsequently advised to vote against it, and an emergency release, rippled 3.1.1, was issued to mark both Batch and its related fixBatchInnerSigs amendment as unsupported, thereby preventing any activation path.
The root cause of the Batch vulnerability was identified as a loop-exit error. When the code encountered a new account whose signing key matched its own, it incorrectly declared success and exited without verifying the remaining signers. This meant that a forged signer entry for any victim account would go unchecked. The exploit path could have enabled an attacker to drain a victim’s account down to its minimum reserve through unauthorized Payment transactions. The replacement, BatchV1_1, has been redesigned with revised authorization logic and is currently flagged in the 3.3 development registry as supported, with a default “No” vote pending validator approval.
Permission Delegation: Rectifying Fee Deduction Errors
Permission Delegation presented a different security concern. A disclosure in September 2025 detailed how an invalid offline-signed transaction could still incur a transaction fee on the delegated account before failing authorization. This occurred because the code checked permissions prior to verifying the signature, and tec-type errors are designed to carry a fee. A malicious actor could have exploited this by repeatedly submitting such transactions with elevated fees, silently depleting a victim account’s XRP balance. The fix reclassifies the relevant error from tec to ter and reorders the checks to ensure no fee is deducted before signature verification. The replacement, PermissionDelegationV1_1, carries the same default “No” designation in the 3.3.0 registry. This pattern of identifying and addressing bugs before mainnet activation aligns with the XRPL’s ongoing security maintenance practices, which have included multiple hotfix releases to resolve protocol-level issues.
New Amendments Target Institutional Tokenization
The remaining three amendments in the xrpld 3.3.0 release are new features designed to cater to the institutional tokenization market. Confidential MPT (Multi-Purpose Token) utilizes elliptic-curve cryptography and zero-knowledge proofs to keep balances and transfer amounts of MPTs private on the public ledger, while still allowing for auditability by designated entities, such as regulators. This feature directly addresses a primary concern for financial institutions evaluating public blockchain infrastructure: the visibility of counterparty exposure. It is intended for tokenized government bonds, real estate, equities, and private credit – asset classes where confidentiality is a fundamental operational requirement.
Sponsored Fees and Reserves will enable banks, issuers, or platforms to cover transaction fees and reserve requirements on behalf of their users, thereby eliminating the need for end-users to hold XRP to transact. This is expected to significantly reduce onboarding friction for institutional deployments. However, it also reignites a structural debate about demand dynamics, as a reduced need for end-users to hold XRP could shift demand towards institutional settlement volume rather than retail token utility.
Dynamic MPT is the third new amendment, allowing token issuers to modify specific properties, fees, metadata, and predefined parameters after issuance without needing to migrate to a new token.
Jazzi Cooper, RippleX’s head of product, announced the five amendments on X, emphasizing that the XRP Ledger has already proven its capability to support tokenized assets at scale. She framed the new features as crucial infrastructure for global transfers, trading, collateralization, and settlement. Cooper confirmed that all five amendments require validator voting before they can be activated.
