Uniswap Example

To setup a liquidity pool, you must first create the tokens in the pair using the ERC20 object. Next, create a liquidity pool (LP) factory using IFactory object. Once this is setup, an unlimited amount of LPs can be created; the procedures for such are as follows:

from defipy import *

user_nm = 'user_intro'
eth_amount = 1000
dai_amount = 1000000

dai = ERC20("DAI", "0x01")
eth = ERC20("ETH", "0x02")

factory = UniswapFactory("ETH pool factory", "0x")
exchg_data = UniswapExchangeData(tkn0 = eth, tkn1 = dai, symbol="LP", address="0x11")
lp = factory.deploy(exchg_data)
lp.add_liquidity("user0", eth_amount, dai_amount, eth_amount, dai_amount)
lp.summary()


#OUTPUT:
Exchange ETH-DAI (LP)
Reserves: ETH = 1000, DAI = 1000000
Liquidity: 31622.776601683792 

Balancer Example

from defipy import *

USER = 'user_test'

amt_dai = 10000000
denorm_wt_dai = 10

amt_eth = 67738.6361731024
denorm_wt_eth = 40

init_pool_shares = 100    

dai = ERC20("DAI", "0x01")
dai.deposit(None, amt_dai)

weth = ERC20("WETH", "0x02")
weth.deposit(None, amt_eth)

bgrp = BalancerVault()
bgrp.add_token(dai, denorm_wt_dai)
bgrp.add_token(weth, denorm_wt_eth)

bfactory = BalancerFactory("WETH pool factory", "0x")
exchg_data = BalancerExchangeData(vault = bgrp, symbol="LP", address="0x1")
lp = bfactory.deploy(exchg_data)
lp.join_pool(bgrp, init_pool_shares, USER)
lp.summary()


#OUTPUT:
Balancer Exchange: DAI|WETH (LP)
Reserves: DAI = 10000000, WETH = 67738.6361731024
Weights: DAI = 0.2, WETH = 0.8
Pool Shares: 100 

StableSwap Example

from defipy import *

USER = 'user_test'

AMPL_COEFF = 2000 

amt_dai = 79566307.559825807715868071
decimal_dai = 18

amt_usdc = 81345068.187939
decimal_usdc = 6

amt_usdt = 55663250.772939
decimal_usdt = 6

dai = ERC20("DAI", "0x01", decimal_dai)
dai.deposit(None, amt_dai)

usdc = ERC20("USDC", "0x02", decimal_usdc)
usdc.deposit(None, amt_usdc)

usdt = ERC20("USDT", "0x03", decimal_usdt)
usdt.deposit(None, amt_usdt)    

sgrp = StableswapVault()
sgrp.add_token(dai)
sgrp.add_token(usdc)
sgrp.add_token(usdt)    

sfactory = StableswapFactory("Pool factory", "0x")
exchg_data = StableswapExchangeData(vault = sgrp, symbol="LP", address="0x11")
lp = sfactory.deploy(exchg_data)
lp.join_pool(sgrp, AMPL_COEFF, USER)
lp.summary()


#OUTPUT:
Stableswap Exchange: DAI-USDC-USDT (LP)
Reserves: DAI = 79566307.55982581, USDC = 81345068.187939, USDT = 55663250.772939
Liquidity: 216573027.91811988
