The Jade upgrade is now live on Morph Mainnet.   
  
Activated on April 8, 2026 at 06:00 UTC, the Jade fork brings two significant changes to the network:  
  
**What's Live**

1. **MorphTx Transaction Type:** The MorphTx transaction type is now active on Morph Mainnet. MorphTx replaces the previous AltFeeTx (type 0x7F) and introduces the Reference Key feature, enabling transaction tracking and indexing via a 32-byte reference identifier. This lays the foundation for more structured, traceable payment settlement on Morph.
2. **MPT State Trie Migration:** Morph Mainnet nodes have completed the migration from zkTrie to Merkle Patricia Trie (MPT). This brings Morph closer to full Ethereum equivalence, improving tooling compatibility and the long-term reliability of the network.
3. General performance optimizations and improvements.

**For Node Operators**  
  
If you have not yet upgraded your node, please do so now. Nodes running older versions may fork and fall out of sync with the network.
