- Proxy: 0x62B52D21db12E4A709a49c043e31adfdAB41FB39
- Verified: https://sepolia.basescan.org/address/0x2ca555a7acfe2da02099a6d950b8665a65f5c861

Base Mainnet:
- V2 Implementation: 0x13A8f49C41133A2f3D5E6cbb18626EE242b0E4f4
- Proxy: 0x9A1f27779561269Ac8bFFdd152D1F8f2C445FC3e
- Verified: https://basescan.org/address/0x13a8f49c41133a2f3d5e6cbb18626ee242b0e4f4

Both contracts successfully upgraded via UUPS pattern with full
backward compatibility. All V1 data preserved, V2 features now active.
