Upcoming network upgrades: What’s coming & why It matters
@FlareNetworks is preparing for two upcoming hard forks that will introduce major improvements to performance, efficiency, and scalability across the ecosystem. These upgrades activate key components of the Cancun/Dencun fork, bringing new EVM features that make smart contracts faster and more cost-efficient.
What these upgrades enable
- More efficient and scalable dApps
- Lower execution costs for advanced applications
- Lays the foundation for new high-performance protocols (including upcoming modular lending innovations - details to be shared later)
Scheduled activation times
- Songbird: November 25, 2025 – 12:00 UTC
- Flare: December 2, 2025 – 12:00 UTC
Key technical improvements
MCOPY opcode
A major improvement to memory operations. Instead of copying data byte-by-byte, MCOPY enables fast, chunk-based transfers — essentially turbocharged memcpy for smart contracts.
TSTORE / TLOAD (Transient Storage)
Provides cheaper temporary storage, ideal for batching, simulations, and other high-throughput contract operations.
These upgrades enhance the C-chain EVM environment and prepare the network for the next generation of applications on Flare.
P-chain & Staking Updates
With this fork, the P-chain introduces dynamic staking fees, where transaction costs are determined by gas consumption and the current gas price. Supporting libraries, including flarejs, have also been upgraded.
Developers should review the latest release notes now and ensure they are using the correct flarejs transaction builders when creating transactions before and after the fork.
Action Required: All node operators must upgrade to go-flare v1.12.0 before the scheduled activation dates. Please review the full technical details here:
