XRPL Amendments Explained
Amendments are the XRP Ledger's mechanism for protocol upgrades — decentralized, backward-compatible, and requiring supermajority validator consensus.
What Are XRPL Amendments?
Amendments are protocol-level changes to the XRP Ledger. Unlike hard forks, amendments are activated through on-chain validator voting. Once an amendment gains 80% support from trusted validators (the UNL) for a continuous two-week period, it automatically activates on the network. No manual coordination or chain split required.
How Amendment Voting Works
Each validator signals support for amendments via its feature votes in every validation message. The ledger tracks the percentage of trusted validators supporting each amendment over a rolling two-week window.
- Threshold: 80% of UNL validators must support the amendment
- Duration: support must be continuous for 2 weeks (256 flag ledgers)
- Activation: automatic once both conditions are met
- Irreversible: once activated, amendments cannot be deactivated

Why Amendments Matter
The amendment system gives the XRP Ledger a unique governance model: upgrades happen on-chain without hard forks, chain splits, or centralized decision-making. Validators independently decide what features to support, and the network evolves only when there is broad consensus. This has enabled the ledger to add major features like AMM and NFTs while maintaining 12+ years of uninterrupted operation.
