Megapot offers a testnet contract and a modified mainnet contract. This allows you to easily test your implementations before deploying code. The only difference between them, aside from the network, is the testnet contract uses a mock USDC token (MPUSDC) which you can freely mint for testing purposes and automatically runs every 24 hours. The modified mainnet contract uses USDC and runs every 10 minutes. Our modified mainnet contract allows you to test in a more realistic environment before deploying to mainnet. It does use real USDC, has a small amount of liquidity, and liquidity deposits are always open to test the liquidity experience. This contract does not run automatically, but you are able to manually run the jackpot for testing purposes.
