The Stellar public network successfully upgraded to Protocol 17 on June 1, 2021, introducing Asset Clawback—a feature enabling businesses to issue regulated financial instruments like bonds and equities while maintaining compliance capabilities.
On June 1, 2021 at 1500 UTC, the Stellar network completed its upgrade to Protocol 17 following validator consensus. The upgrade introduces Asset Clawback, a new feature designed to allow regulated financial instrument issuers (money market funds, bonds, equities) to comply with regulatory requirements by revoking assets when necessary. The feature does not affect existing assets, balances, or accounts but opens new possibilities for regulated asset issuance. The upgrade required coordination across the ecosystem, with validators voting to approve the new protocol version. Developers using Stellar-related software need to upgrade to Protocol 17 to avoid errors when encountering new clawback flags or operations.
