XRPL Activates fixCleanup3_4_0 Amendment to Resolve Permission Delegation Flaw

The XRP Ledger activated the fixCleanup3_4_0 amendment on Nov. 4, 2026, at ledger index 108,112,129, introducing a bundle of technical corrections across multiple core protocols ². The amendment reached activation after sustaining validator majority across a mandatory two-week voting window ².

A critical correction within the update addresses the ledger's permission delegation engine ¹, ². According to XRPL documentation, users were previously advised against delegating the granular "PaymentBurn" permission ¹. Before the activation of fixCleanup3_4_0, accounts granted the PaymentBurn permission could inadvertently mint new fungible assets, such as trust line tokens or Multi-Purpose Tokens (MPTs), under certain transaction conditions ¹. The activation removes this risk, restricting PaymentBurn delegates exclusively to transactions that destroy tokens without dropping balances below zero ¹.

Broad Protocol Maintenance

Beyond fixing permission delegation logic, fixCleanup3_4_0 delivers targeted cleanups across several ledger features introduced in the xrpld 3.4.0 software release ². Explorer data records that the amendment includes fixes for Single Asset Vaults, the native Lending Protocol, automated market makers (AMMs), the permissioned decentralized exchange (DEX), trust lines, NFTs, escrow, sponsorship mechanisms, and cryptographic signing functions ². Earlier network discussions also focused on validator reliability; for instance, core developers recently addressed an XRPL bug dropping rotated validators from amendment votes to maintain consensus stability.

Network data shows the amendment originally entered validator voting after being introduced in xrpld 3.4.0 on Sept. 17, 2026 ². An initial voting attempt lost its required validator majority on Oct. 21, 2026, before regaining consensus the same day to begin its successful 14-day activation countdown ². At the time of writing, native asset $XRP traded at $1.32.
