When you mint a farm, you get ownership of a NFT which is also assigned a unique address on the Blockchain. This NFT has custody of your resources while you play the game.
When you earn $SFL or gather resources they are minted against the unique address that is associated to your farm NFT. They will not appear in your personal wallet until you withdraw them from the game.
You can find the farm's blockchain address by going to Goblin Town and clicking on the bank.
If you go to https://polygonscan.com/ and enter your address, you will be able to see the SFL and all of the items (ERC1155 tab) that your farm owns on the Blockchain.
Depositing SFL and items
Only send SFL or Sunflower Land Items to your farm's address. MATIC and other tokens sent will be unrecoverable
You can use your farm's address that is found in the bank and send resources directly to this address.
How to send SFL?

Under 'Assets', find SFL and click 'Send'
