Niftyswap is a decentralized token swap protocol for ERC-1155 tokens on Ethereum. In other words, Niftyswap is Uniswap for ERC-1155 tokens.
For detailed documentation on the Niftyswap Protocol and how to use it, please read the SPECIFICATION.
Niftyswap is an implementation of Uniswap, a protocol for automated token exchange on Ethereum. While Uniswap is for trading ERC-20 tokens, Niftyswap is a protocol for ERC-1155 tokens. Both are designed to favor ease of use and provide guaranteed access to liquidity on-chain.
Most exchanges maintain an order book and facilitate matches between buyers and sellers. Niftyswap smart contracts hold liquidity reserves of various tokens, and trades are executed directly against these reserves. Prices are set automatically using the constant product $x*y = K$ market maker mechanism, which keeps overall reserves in relative equilibrium. Reserves are pooled between a network of liquidity providers who supply the system with tokens in exchange for a proportional share of transaction fees.
An important feature of Niftyswap is the utilization of a factory/registry contract that deploys a separate exchange contract for each ERC-1155 token contract. These exchange contracts each hold independent reserves of a single fungible ERC-1155 currency and their associated ERC-1155 token id. This allows trades between the Currency and the ERC-1155 tokens based on the relative supplies.

Install
yarn add @0xsequence/niftyswap or npm install @0xsequence/niftyswap
There are some differences compared to the original Uniswap that we would like to outline below:
1.For ERC-1155 tokens, not ERC-20s
2.Base currency is not ETH, but needs to be an ERC-1155
3.Liquidity fee is 0.5% instead of 0.3%
4.All fees are taken from base currency (Uniswap takes trading fees on both sides). This will lead to some small inneficiencies which will be corrected via arbitrage.
5.Users do not need to set approvals before their first trade
•NiftyswapExchange.sol: The exchange contract that handles the logic for exchanging assets for a given base token.
•NiftyswapFactory.sol: The exchange factory that allows the creation of nifyswap exchanges for the tokens of a given ERC-1155 token conract and an ERC-1155 base currency.
Niftyswap has been audited by two independant parties and all issues discovered were addressed.
•Agustín Aguilar**
•Consensys Diligence
** Agustín was hired as a full-time employee at Horizon after the audit was completed. Agustín did not take part in the writing of Niftyswap contracts.
This repository is configured as a yarn workspace, and has multiple pacakge.json files. Specifically, we have the root ./package.json for the development environment, contract compilation and testing. Contract source code and distribution files are packaged in "src/package.json".
To release a new version, make sure to bump the version, tag it, and run yarn release. The release command will publish the @0xsequence/niftyswap package in the "src/" folder, separate from the root package. The advantage here is that application developers who consume @0xsequence/niftyswap aren't required to install any of the devDependencies in their toolchains as our build and contract packages are separated.
