Suika
Advanced ERC-721 Marketplace
A standard ERC-721 token with buy, sell, auction, royalties and token payments
Language: Solidity v8.2
What is Suika Smart Contract?
ERC-721 is a standard for non-fungible tokens (NFT) or deeds. NFT are useful to represent digital or physical assets that cannot be divided, for example:
- Properties (houses, art pieces)
- Virtual collectibles (virtual pets, cards)
- “Negative value” assets (loans, burdens, and other responsibilities)
One of the most famous ERC-721 token is the CryptoKitties. The most expensive CryptoKitty to date is Dragon, with a price of 600 Ether (USD 232K value at the moment of writing).
But NFT is not only about kitties. There are all kinds of virtual assets. OpenSea, one of the biggest Marketplaces for NFT, has thousands of assets from Virtual Worlds to Football Fantasy Cards.
During late 2020 and 2021 the NFT market has reached incredible levels of monetization in different areas including arts, music, memes, tweets and all kinds of NFT. One of the most notable ones was the Beeple, Everydays – The First 5000 Days sold for more than 69M$

Formats
- Image: an image is a unique file like a piece of art, a picture, profile, etc. Formats are .png, .jpg or .gif
- Video: a recording, animation, short movie, etc. For videos you can choose multiple files, but all files should correspond to same asset with different format, i.e. .mp4 and .ogv. This is because some video formats are more suitable than others on different devices.
- Audio: a song, podcast, effects, etc. You can choose multiple files, but all files should correspond to same asset, i.e. .mp3 and .ogg.
- Documents: this is a unique file that correspond to a property, license, loan, debt or any other document you need.
IPFS Support
You can now store your assets on the Inter Planetary File System (IPFS) decentralized network.

Audits
During the first quarter of 2022, we carried out a series of audits on a first batch of smart contracts. These audits included the Suika smart contract and were performed by an external company as well as our internal team.
According to the standard audit assessment, solidity smart contracts are “Secured”.
