KnownOrigin V3 Smart Contracts
Discover, buy and collect rare digital artwork
## Core Guiding Principles & Features
* GAS efficient - every byte counts, store only what is required `creator`, `edition size` & `metadata` but ensuring onchain provence
* [ERC-721](https://eips.ethereum.org/EIPS/eip-721) compliant NFTs
* Ability to mint single 1 of 1 NFTs
* Ability to mint batches of NFT (multi-editions)
* Collaboration support for `1..n` collaborators with royalties - predetermined addresses
* Generalise feature set to work with all KO artists and collectors in a modula fashion
* Immutable by design with onchain purchase and bidding histories
* Creative works deserve traceable onchain histories, think of the future!
* Replace whitelisting with merkle proofs for minting access to reduce operational overheads
* Support for [ERC-2981: Royalty Standard](https://eips.ethereum.org/EIPS/eip-2981)
* Support for [ERC-998 Top-down ERC-20 composable](https://eips.ethereum.org/EIPS/eip-998) (optional)
* Single composable `ERC721`
* Multiple composable `ERC20`
* Support for [ERC-2309: Consecutive batch mint](https://eips.ethereum.org/EIPS/eip-2309) (optional)
* Support for [Rarible V2 royalties standard](https://docs.rarible.com/asset/royalties-schema) (optional)
* Support for a proxy management account for creatives (optional)
* Support programmable/dynamic token URIs in the future (future iteration)
* Support metadata updates before the first sale has been made (optional)
* Sealed Metadata: Support to set a one time `perma-web` backup of token metadata
* Sales mechanics (see `./marketplace`)
* `primary` market
* `Buy now` - includes start date
* `Open Offers` - includes bidder lockout period and start date
* `Stepped sales` - linear price increases per purchase from an edition
* `24hr reserve auctions` - includes start date, reserve price with 24hr countdown + 15min extension window
* `Early access sales` - gated sales behind lists of collectors, customisable drop phases
* `secondary` market
* `Buy now` - includes start date
* `Open Token Offers` - offers made on a specific token
* `Open Edition Offers` - open offer on an edition, any edition owner can action
* `24hr reserve auctions` - includes start date, reserve price with 24hr countdown + 15min extension window
### GAS & Coverage
* `GAS` report can be found [here](./gas-report-output.md) and generated on demand via `npm run gas`
* Contract size report found [here](./contract-size.md) or generated on demand via `npm run contract-size`
* Code coverage generation via `npm run coverage` output in `./coverage` folder
### Audits
* Public audits can be seen in `audits`
* Core NFT and marketplaces - CoinFabrik audit can be seen [here](https://blog.coinfabrik.com/known-origin-digital-asset-audit/)
* Early access / gated sales - CoinFabrik audit can be seen **Awaiting published results**
### Subgraph
* KO uses a mixture of public Subgraph and a currently private indexer to create a view on-top of these contracts
* Subgraph can be accessed [here](https://thegraph.com/legacy-explorer/subgraph/knownorigin/known-origin)
* Subgraph source code be accessed [here](https://github.com/knownorigin/known-origin-subgraph)

### How to?
Use `hardhat` deploy for - see `/scripts` folder for more info e.g.
`npx hardhat run --network rinkeby ./scripts/X_my_script.js`
To verify also try hardhat but this sometimes fails, and you need to use the flat contracts.
