Demo project: https://place.justice.exchange/
Let’s you draw on a public canvas, the cost is 1 Justice token per pixel and saves everything on chain.
Requires some Justice tokens bridged to Optimism to use. Cost is 1 JUSTICE token per pixel, 512px max. Also requires Optimism eth gas fee. (Anyone can bridge any ERC20 token to Optimism using their official bridge OP Mainnet Gateway - or using https://bridge.justice.exchange which is the exactly the same as using optimism’s official bridge)
Full transparency since the DAO doesn’t have an Optimism JUSTICE treasury - any Justice tokens spent during the test phase are sent to an address that I control (it should be a very very low amount, only up to 512 JUSTICE tokens max per draw). This can easily be changed to go to a DAO treasury address in the future should we ever decide to use this project officially. I will donate all of the tokens used during the testing phase to the treasury manually.
This was mainly made to show what the purpose of bridging Eth to another chain would be good for (Optimism has much lower fees).
You WILL get browser + MetaMask warnings if you use this, use it at your own risk and only from a separate wallet account that has a low amount of Eth and Justice.
Warnings will likely go away if the project is fully audited and polished.
