This project is intended to provide an easy and efficient way to exchange tokens and XTZ on Tezos blockchain in a wide number of directions. Using smart contracts listed in this repo users can add their tokens to exchange, provide liquidity, and potentially make a profit in a fully decentralized way.
The current implementation supports FA1.2 and FA2.
The solution consists of 6 types of contracts:
Factory
- singleton used to deploy new TokenX-XTZ exchange pair;Dex
- contract for TokenX-XTZ pair exchanges;TTDex
- contract for TokenX-TokenY pair exchanges;Token
- FA token implementation.BakerRegistry
- bakery registrar.MetadataStorage
- contract to store and upgrade the shares token metadata.

-
Installed NodeJS (tested with NodeJS v12+)
-
Installed Yarn (NPM isn't working properly with
[email protected]
) -
Installed Ligo:
curl https://gitlab.com/ligolang/ligo/raw/dev/scripts/installer.sh | bash -s "next"
- Installed node modules:
cd quipuswap-core && yarn
- Configure
truffle-config.js
if needed.
To compile and deploy contracts to Delphinet
- Chose configure the version -
FA12
orFA2
- by settingEXCHANGE_TOKEN_STANDARD
in.env
and run:
yarn migrate
For other networks:
yarn migrate --network NAME
Contracts are processed in the following stages:
- Compilation
- Deployment
- Configuration
- Interactions on-chain
As the Quipuswap supports 2 token standards that vary only in the token interface implementation and the inter contract communication between Dex and external tokens, the shared codebase is used. Therefore to work with the specific standard version, you should configure it by setting EXCHANGE_TOKEN_STANDARD
in .env
to either FA12
or FA2
.
To compile the contracts run:
yarn compile
Artifacts are stored in the build/contracts
directory.
For deployment step the following command should be used:
yarn migrate
Addresses of deployed contracts are displayed in terminal. At this stage, new MetadataStorage, Factory are originated. Aditionaly, for testnets two new pairs are deployed.
If you'd like to run tests on the local environment, you might want to run ganache-cli
for Tezos using the following command:
yarn start-sandbox
Truffle framework is used for testing. Run:
yarn test
NOTE: if you want to use a different network, configure truffle-config.js
. If you need to use a different standard, configure $EXCHANGE_TOKEN_STANDARD
in .env
