How to deploy a NFT collection on Starknet with Starksheet

Last Thursday, eniwhere\_ challenged me on twitter with a "wen mint" after I posted a midjourney generated image in response to a public call-out by Only Dust. Using Starksheet, I have been able to no-code deploy the collection now called the Dusty Pilots with current floor price at 0.035 ETH and volume 0.2579 ETH in less that half-a-day, spending most of my time in the image generation and curation process.

How to debug a Chainlink VRF tx

Recently, I released a new on-chain CC0 NFT project called the co-bots. This project has also a specificity: during the minting process, at some given checkpoints, it randomly rewards on of the early minters with a giveaway in ETH taken from the contract balance.

How I deployed an on-chain 10k pfp project for less than 0.1 ETH

Yes, as few as 0.1 ETH or more precisely as you can see on the etherscan contract transaction page for as few as 0.096212736214 ETH, most of it being the contract itself (0.075760070358 ETH), i.e. all the general decoding functions that could be embedded once for all in a library. In other words, the image part of the cost is only about 0.02 ETH!

While it is quite straightforward to use the Chainlink VRF V2 oracle, the Request & Receive Data cycle is a bit less easy to use on a local network (e.g. a hardhat node for testing) where there is no Chainlink node listening to the calls.

The single-line error that was worth 4 ETH

Yes, 4 ETH, or more precisely 4,09337014 ETH, which was worth, at the time of fixing the bug, 12,516.22 US$. How all this happened with one single line of code updated 4 hours before the launch? This is the post-mortem of the bug.
