XRP Ledger Restarts Permission Delegation Upgrade After Fixing Fee-Drain Flaw

XRP Ledger's revised PermissionDelegationV1_1 amendment entered a 14-day activation countdown on September 21 after gaining support from 29 of 35 trusted validators. The upgrade is projected to activate on October 5 at 11:18 UTC, provided validator support remains above the protocol's required threshold, according to CoinDesk.

PermissionDelegationV1_1 begins its 14-day activation countdown

PermissionDelegationV1_1 must retain support from more than 80% of trusted validators for two weeks before activation under the XRP Ledger amendment documentation. If support falls to 80% or below during that period, the activation countdown restarts. The 29-validator tally placed PermissionDelegationV1_1 above the required threshold at the start of its current activation window, while the October 5 activation timing remains conditional on support staying above that threshold, as outlined in the documentation.

xrpld 3.3.0 replaces blocked amendment after fee-drain bug

PermissionDelegationV1_1 is included in xrpld 3.3.0 and replaces the original PermissionDelegation amendment. The revised version addresses a critical bug in the earlier implementation, XRP Ledger said in its xrpld 3.3.0 release announcement.

Under the original flaw, invalid delegated transactions could charge fees to another account before signature verification. That created the potential to drain the account's XRP balance. Validators blocked the original amendment before it reached mainnet activation, according to XRP Ledger's vulnerability disclosure report.

What narrowly scoped delegation would allow

Permission delegation would let an account grant another account defined permissions without transferring full control of its signing keys. The feature is intended to separate specific account functions while keeping broader key authority with the original account holder.

For now, its route to activation depends on trusted-validator support remaining above 80% through the two-week window.
