Service providers have until February 18, 06:00 UTC to test their integrations with Stargate before the upgrades are launched on Cosmos Hub.
Wallets and Explorers should test to ensure that the legacy Amino endpoints provided on the new chains are compatible with existing services. It is highly recommended to start planning a transition to Protobuf endpoints as Amino support is expected to be discontinued in the future.
Exchanges should ensure their signing and querying software is ready by testing the new features against their infrastructure ahead of the Stargate upgrade. Use the Stargate IBC Skill Matrix to guide you in supporting IBC with your upgrades.
Prepare for Stargate by upgrading your applications and modules to support the latest Cosmos SDK 0.40.0 release. See the resources below for migration guides.
To implement the Stargate upgrades, validators should prepare by helping to run the final Stargate testnet.
The future of Cosmos depends on you, Cosmonauts!

Stargate involves a lot of breaking changes that may make it difficult for you to upgrade, if you have already written a lot of code for Cosmos SDK 0.37/0.38.
The community supports an SDK 0.39 Launchpad release that includes backported bug fixes. The Cosmos development teams are working together to document a clean migration path from Launchpad to a stable Stargate release.
