⚠️ Important Notice All nodes on Sonic mainnet and testnet must upgrade to 2.1.2 immediately to avoid disconnection. This release introduces native fee subsidies and critical security improvements, replacing the earlier v2.1 ahead of Sonic’s full mainnet upgrade to Pectra compatibility. This applies to: • Validators • RPC Providers • Archive Nodes • Exchanges • Other Node Operators Once upgraded, your nodes will continue to operate on the current mainnet until the full transition on November 3rd, 2025, 15:00 CET. The upgrade is backward compatible. Find the full upgrade tutorial below. For questions, contact @0xSeg. 🔗 https://docs.soniclabs.com/sonic/node-deployment/upgrade-instructions-2.1(Sonic)
