Stellar public network upgraded to Protocol 15 at 1600 UTC, introducing Claimable Balances and Sponsored Reserves features to enable more user-friendly app development on the network.
The Stellar network successfully upgraded to Protocol 15 after months of preparation, introducing two new features: Claimable Balances and Sponsored Reserves. These features are designed to make it easier to build user-friendly applications on Stellar. The upgrade was decided through validator voting, the same consensus mechanism used for transaction sets. Developers must upgrade their Stellar-related software to Protocol 15 to avoid errors; Stellar Core will throw immediate errors if outdated, while Horizon and SDKs may function temporarily before encountering new operations. The ecosystem coordinated extensively to prepare for this major network-wide change.
