The first upgrade of CKB, ckb2021, is in progress. Older versions of the SDK have compatibility issues that may lead to the creation of incorrect transactions, resulting in lost assets. Please be sure to upgrade to the latest version of the SDK before the upgrade is activated:
- Java SDK v0.101.1 or newer
- Golang SDK v0.101.1 or newer
- There is logic to treat
hash_typeas 1 if it is not 0. In ckb2021, the value may also be 2, and more values will be introduced in later upgrades. Developers must check whether code has the same issue if they handle this field themselves.
