The Stellar Development Foundation announces Protocol 17 upgrade with a new Asset Clawback feature. Developers and node operators must update Stellar Core, Horizon, and SDKs before the June 1, 2021 network upgrade vote.
The Stellar network is preparing for Protocol 17, which introduces an Asset Clawback feature allowing issuers to claw back previously issued assets. The upgrade requires all developers and operators to install updated versions of Stellar infrastructure and SDKs in advance. Key dates include May 4, 2021 for testnet upgrade and June 1, 2021 for the public network upgrade vote. The guide provides specific version requirements for Stellar Core v17.1.0, Horizon v2.3.0, and multiple SDKs across JavaScript, Java, Go, Python, iOS, C#, Scala, Flutter, and Ruby. Horizon operators can use the new Captive Core architecture or maintain legacy setups with standalone Stellar Core nodes. Validators can vote for the upgrade using specific commands, and developers with custom integrations should review the JS SDK issue for necessary code changes.
