Indelible Labs is free for creators. However, we do offer some premium features that holders of Indelible Pro get access to for free.
Not at all! You can use SVGs as traits to create non-pixel art collections.
Each trait has a file size limit of 2 KB.
You can have up to 15 layers and each layer can have up to 100 KB worth of traits.
On-chain NFTs are NFTs where all data to create the image is stored inside the smart contract on the blockchain instead of storing just a url that points to an image stored somewhere else that can be taken down at any time. On-chain NFTs can never been taken down as long as the Ethereum blockchain exists.
There are a lot of variables that go into the cost -- such as, the cost of gas, the amount of traits, and how large the trait files are. Assuming gwei is 20, the smart contract would cost roughly ~0.15 ETH and if the traits were on average 300 bytes and you had 100 traits it would be roughly ~0.3 ETH to upload the traits for a total of ~0.45 ETH.
You can upload PNGs, JPEGs, GIFs, SVGs, and WEBP.
You can create an animated NFT collection by using GIFs for some of the traits. Animations currenly only work on the Indelible Labs minting site (any browser) and on OpenSea (Chrome only). Other market places, like LooksRare, convert the SVG to a PNG that doesn't animate.
There is a toggle on the smart contract that allows you to let your holders enable off-chain rendering at an individual token level. This will take advantage of our API to convert the on-chain SVG into an off-chain PNG that will work with Twitter's hexagon. This off-chain rendering can be enabled by each holder for each of their tokens but also can be toggled on or off at a collection level by the owner of the smart contract.
