test for 1202

熟悉代码

测试单一测试文件 npx buidler test ./test/poolToken.ts

跑一些测试脚本 npx buidler test001 --network localhost

或者 npx buidler test001 --network ropsten

修改了test001的代码，实现了deploy BalancerPool 的功能

npx buidler test001 --balancer-factory 0x8858eeB3DfffA017D4BCE9801D340D36Cf895CCf --network localhost

20.11.13 CEP Smart Pools

CEP Smart Pools are asset management agnostic(currently Balancer only) Decentralised Traded Funds. They share a common interface to make them easy to integrate in other products.

All Smart Pools are fully upgradeable to make it easy to add features and optimise gas usage at later stages.

Development

Setup the dev enviroment

Clone this repo. And copy the contents of env.example to a new file called .env and edit the the relevant values inside. DO NOT share this file with anyone as it will contain sensitive data.

Install all dependencies:

npm i hardhat

yarn

Build the project:

yarn build

Run the tests:

yarn test

Create coverage report:

yarn coverage

Running mainnet/testnet test

To test a new implementation in testnet conditions. Set the implementation of a test pool to the new version and run the following script.

npx buidler deploy-smart-pool-implementation-complete --impl-name DAO --network ropsten

deploy on localhost

Step1: launch localhost node localhost:8545

npx buidler node

Step2: run the deploy scripts on the localhost ndoe

npx buidler deploy-smart-pool-implementation-complete --impl-name DAO --network localhost

Test Single File

test single test scripts poolToken.ts

npx buidler test ./test/poolToken.ts

test basic pool functions:

npx buidler test ./test/basicPoolFunctionality.ts

test advancedPoolFunctionality

npx buidler test ./test/advancedPoolFunctionality.ts

test cap functions

npx buidler test ./test/capPoolFunctionality.ts

test ProxiedFactory test script

npx buidler test ./test/pProxiedFactory.ts

npx buidler test ./test/reentryProtection.ts

test safeApproval test script

npx buidler test ./test/safeApproval.ts

Integration

Adding and removing liquidity

To add liquidity approve the smart pool to pull the underlying tokens. And call:

function joinPool(uint256 _amount) external;

To remove liquidity:

function exitPool(uint256 _amount) external;

Getting pool details

To get the underlying tokens call:

function getTokens() external view returns(address[] memory);

To get the underlying tokens and amounts needed to mint a certain amount of pool shares call:

function calcTokensForAmount(uint256 _amount) external view returns(address[] memory tokens, uint256[] memory amounts);

Balancer smart pool specific

Get the address of the underlying balancer pool:

function getBPool() external view returns(address);

Get the swap fee:

function getSwapFee() external view returns (uint256);

Get if trading is enabled on the underlying balancer pool:

function isPublicSwap() external view returns (bool);

Capped pool specific

Some pools have a cap which limits the totalSupply of the pool shares token. To get the cap you call:

function getCap() external view returns(uint256);
