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:
import {
abi as FACTORY_ABI,
bytecode as FACTORY_BYTECODE,
} from '@uniswap/v3-core/artifacts/contracts/UniswapV3Factory.sol/UniswapV3Factory.json'
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.:
import '@uniswap/v3-core/contracts/interfaces/IUniswapV3Pool.sol';
contract MyContract {
IUniswapV3Pool pool;
function doSomethingWithPool() {
// pool.swap(...);
}
}
