The XRP Ledger is moving to activate fixCleanup3_4_0 on November 4 after validator support recovered to 33 of 35 votes. The amendment closes a permissions flaw in PaymentBurn that let some accounts create issued tokens they were only allowed to burn, including stablecoin-related tokens.

Key claims & sources

✓
The issue affects stablecoin minting permissions on the XRP Ledger and involves partners that issue tokens on the network.
✓
fixCleanup3_4_0 had 33 of 35 trusted validator votes on Monday and was scheduled to activate on November 4.
✓
Support for the amendment dropped below the activation threshold on October 21, which reset the countdown before it recovered.
✓
The flaw is in PaymentBurn and can let accounts approved only to burn issued tokens create new ones under certain conditions.
✓
The amendment is designed to stop accounts with only PaymentBurn authority from minting new trust line tokens or MPTs.

What it means

XRPL's amendment system lets validators vote in new rules, with activation requiring roughly 80% support sustained for fourteen days. PaymentBurn belongs to a delegation feature that lets issuers hand limited authority to third parties, separating the right to destroy tokens from the right to create them. The flaw under fixCleanup3_4_0 blurs that separation: in some conditions, an account cleared only to burn tokens can also mint trust line tokens or MPTs it was never meant to issue.

Once fixCleanup3_4_0 activates, burn-only delegates lose any residual ability to mint, closing a path that stablecoin issuers and custodians using XRPL's delegation model would otherwise need to police manually. With 33 of 35 trusted validators already backing it, token issuers gain assurance that a narrowly scoped permission stays narrow, while anyone who built workarounds or monitoring around the bug's existence can retire that extra layer once the fix is live.

The episode tests how much trust a 'permissioned delegation' model deserves when partners increasingly issue stablecoins directly on XRPL rather than through separate custodial rails. Splitting mint and burn authority is meant to limit blast radius if a delegated key is compromised; a bug letting burn rights quietly become mint rights undercuts that promise. It is a reminder that fine-grained permission systems are only as reliable as the code enforcing the boundaries between them. (per coindesk.com)

Activation is projected for November 4, contingent on validator support holding above the 80% threshold for the required fourteen-day window. Support already dipped below that line on October 21, resetting an earlier October 23 target, so a repeat dip would push the date again rather than cancel the fix outright. The number to track is the trusted-validator count, currently 33 of 35, in the days leading into November 4.
