In an ambitious effort to enhance the XRP Ledger, a series of technical upgrades, known as the fixCleanup3_4_0 package, are slated to activate as early as October 23, 2026. This follows a two-week rollout period initiated on October 5, according to data from XRPScan. The upgrades aim to refine protocol functionalities and address various technical issues, promising noteworthy improvements in the network’s performance.
Close Monitoring of Validator Support Threshold
A critical requirement for the new changes to take effect is maintaining validator support above 80 percent. Should the approval ratings dip even once to 80 percent or below, the proposal will be rejected, necessitating a reset of the 14-day activation clock. Currently, out of 32 validators, 26 have voted in favor, resulting in a support level of 81.25 percent. The fixCleanup3_4_0 package was introduced with the version 3.4.0 release of xrpld, the reference server application for the XRP Ledger protocol, permanently setting the rules for network operations.
Validator support must remain above 80 percent; if it falls below this threshold, the change is rejected, and the voting process restarts.
Enhancements Across Various Components
This upgrade addresses a wide array of components, including Single Asset Vaults, Lending Protocol, automated market makers, permissioned DEX structure, trust line records, NFTs, MPTs, Escrow, Sponsorship, transaction signing, and delegation mechanisms. These improvements are aimed at bolstering the security of the network’s permission structure, coming on the heels of recent Permission Delegation and Batch amendments.
Significantly, a key vulnerability in the Permission Delegation module is mitigated. Until the activation of fixCleanup3_4_0, users were unable to securely delegate permissions like PaymentBurn. Under the existing structure, a delegate holding such permission could, under certain conditions, inadvertently mint new tokens. The update rectifies this unintended consequence without impacting other intricate permissions.
Until fixCleanup3_4_0 is activated, users cannot delegate PaymentBurn permissions; the current setup potentially allows unauthorized token creation under specific conditions.
Technical Refinements in AMM, NFT, and Escrow Protocols
The update introduces modifications to the permissioned DEX by excluding proposals for deleted fields from immutability checks, preventing rule infractions when altering proposals across fields. Furthermore, domain verifications are increasingly stringent.
Within AMMClawback operations, two primary issues are addressed. These include preventing silent zero reversal for MPT amounts reduced to zero due to integer rounding, and allowing the bypass of ownership reserve checks when automatically creating matching asset entries. This ensures that compliance-related reversals are not obstructed due to reserve conditions.
Additionally, the package refines NFT processing by rejecting proposals containing fake XRP amounts and exempts NFToken offers created by an IOU issuer from its own global freeze rule. Moreover, the updates unlock owner reserves through EscrowCancel and EscrowFinish transactions, ensuring that IOU returns to owners do not fail due to reserve limitations.
Consistency Sought in Vault and Lending Transactions
Also addressed are issues related to precision and rounding in VaultDeposit, VaultWithdraw, and VaultClawback transactions, striving to preserve the balance integrity between the observed total asset, available asset, and share supply of any vault. This restructuring enhances controls in freezing, authorization, credentialing, and target address verification for Single Asset Vaults and the Lending Protocol.
Key intentions include excluding defaulted loans from asset freezing, rejecting pseudo-accounts that cannot engage in transactions, verifying withdrawal addresses for permissioned fields, and blocking PaymentBurns that surpass the zero-balance threshold. These refinements are essential steps towards consolidating XRP Ledger’s reliability and functionality.
