Free Lunch is an experiment to test free relay and have some fun. You can follow the steps below to relay pixel art for free on the Bitcoin P2P network.

1. Download and run electrum wallet v4.6.2
2. Use electrum.labrie.ca:50002:s as the server in network settings.
3. Write script(OP_RETURN 46524545204C554E4348) in the payto field, sign and broadcast this transaction with a 0.1 sat/vB fee rate.
4. Use the change output from step 3 as input to create another OP_RETURN transaction:
   • Use freelunch.lol to draw pixel art and encode it as hex
   • Write script(OP_RETURN hex) in the payto field, sign and broadcast this transaction with a 0.1 sat/vB fee rate
5. The pixel art from step 4 becomes the first in this chain and you can create more by spending the change output from each transaction.

If you want these transactions to use a lower fee rate (< 0.1 sat/vB), one of these nodes could be helpful:
