XRP Ledger Developers Propose Four Fixes to Strengthen Token Approval Process

XRP Ledger developers are taking steps to address vulnerabilities in the approval process for restricted tokens by proposing four amendments under the initiative named fixCleanup3_5_0. These changes aim to ensure that only accounts with explicit issuer approval can hold such tokens, thereby enhancing the security and compliance framework of the network.

Proposed Changes Overview

• Tighter Trust-Line Management: The amendments will enforce consistent approval requirements across different transaction types, ensuring that only authorized accounts can hold restricted tokens.
• Automated Market Maker (AMM) Pool Checks: A new requirement will mandate that accounts must have the necessary authorization for both assets in an AMM pool before acquiring liquidity provider tokens.
• Existing Balances Authorization: The proposals will prevent accounts with unapproved trust lines from receiving additional restricted tokens, thereby closing loopholes that allowed unauthorized access.
• Return of Tokens: Holders of unapproved restricted tokens will generally only be able to return these tokens to the issuer unless their account is authorized.

The XRP Ledger Foundation has characterized these proposals as routine improvements to the protocol's safeguards, with no known cases of exploitation reported. The changes are still in the proposal stage and require support from over 80% of trusted validators for activation.

Next Steps for Implementation

For the proposed amendments to go live, they must first be merged into the main XRPL software and then receive sustained validator support for two consecutive weeks. The foundation has emphasized that these changes are not a response to any security incident but rather an effort to strengthen the overall integrity of the protocol.
