Splice 0.5.16, coming to DevNet on March 23rd, introduces new Daml models that will impact some exchanges and applications.
Action:
All exchanges and wallets that parse AmuletRules_Transfer transactions directly must either update their parsing methods to the new transfer workflows, or move to CIP-0056 token standard transfers.
All application developers who directly depend on splice-amulet models older than version 0.1.17 must recompile to a version greater than or equal to 0.1.17.
The Daml models requiring these changes will take effect on the following dates:
DevNet: Apr 7, 2026
TestNet: Apr 21, 2026
MainNet: May 5, 2026
