Oil Rig introduces the first Proof-of-Work token on Solana, bringing CPU-based mining back to Solana. You can start mining $OIL by simply visiting https://oilrig.io, entering your SOL address, and clicking "Start Drilling". The system uses a custom SHA-256 algorithm optimized exclusively for CPUs. When you find a barrel, the entire barrel reward pool is instantly sent to your address, funded by creator rewards that auto-buy $OIL every 3 minutes.
