This repository contains the core smart contracts for the Uniswap V3 Protocol.
For higher level contracts, see the [uniswap-v3-periphery](https://github.com/Uniswap/uniswap-v3-periphery)
repository.
## Bug bounty
This repository is subject to the Uniswap V3 bug bounty program, per the terms defined [here](./bug-bounty.md).
## Local deployment
In order to deploy this code to a local testnet, you should install the npm package
`@uniswap/v3-core`
and import the factory bytecode located at
`@uniswap/v3-core/artifacts/contracts/UniswapV3Factory.sol/UniswapV3Factory.json`.
For example:
```typescript
import {
abi as FACTORY_ABI,
bytecode as FACTORY_BYTECODE,
} from '@uniswap/v3-core/artifacts/contracts/UniswapV3Factory.sol/UniswapV3Factory.json'
// deploy the bytecode
```
This will ensure that you are testing against the same bytecode that is deployed to
mainnet and public testnets, and all Uniswap code will correctly interoperate with
your local deployment.
## Using solidity interfaces
The Uniswap v3 interfaces are available for import into solidity smart contracts
via the npm artifact `@uniswap/v3-core`, e.g.:
```solidity
import '@uniswap/v3-core/contracts/interfaces/IUniswapV3Pool.sol';
contract MyContract {
IUniswapV3Pool pool;
function doSomethingWithPool() {
// pool.swap(...);
}
}
```
