Usage

Subgraphs

This SDK uses subgraphs to obtain information about ICHI vaults. The subgraphs are deployed in the Subgraph Studio and published on Arbitrum One. If you prefer to use published subgraphs, you need to add your subgraph API key to the SUBGRAPH_API_KEY environment variable. Otherwise, the SDK will use the subgraph's Studio endpoint.

Vault

1. approveDepositToken()

param	type	default	required
accountAddress	string	-	true
tokenIdx	0 | 1	-	true
vaultAddress	string	-	true
jsonProvider	JsonRpcProvider	-	true
dex	SupportedDex	-	true
amount	string | number | BigNumber	undefined	false
overrides	Overrides	undefined	false

This function approves tokens for deposit into the vault and must be called before the deposit() function. The 'amount' parameter can be either a string or a number, representing the number of tokens in major units. For instance, if the deposit token is wETH, 'amount' being equal to 0.5 or '0.5' signifies 0.5 wETH. If the 'amount' parameter is not specified the token will be approved for the maximum allowable amount.

import { Web3Provider } from '@ethersproject/providers';
import { approveDepositToken, SupportedDex } from '@ichidao/ichi-vaults-sdk';

const web3Provider = new Web3Provider(YOUR_WEB3_PROVIDER);
const vaultAddress = "0x3ac9...a5f132"
const accountAddress = "0xaaaa...aaaaaa"
const amount = 100
const dex = SupportedDex.UniswapV3

const txnDetails = await approveDepositToken(
    accountAddress,
    0, // token idx can be 0 or 1
    vaultAddress,
    web3Provider,
    dex,
    amount // (optional)
);

await txnDetails.wait();

// can now deposit token0
// ...

2. deposit()

param	type	default	required
accountAddress	string	-	true
amount0	string | number | BigNumber	-	true
amount1	string | number | BigNumber	-	true
vaultAddress	string	-	true
jsonProvider	JsonRpcProvider	-	true
dex	SupportedDex	-	true
percentSlippage	number	1	false
overrides	Overrides	undefined	false

This function facilitates deposits into the vault. The 'amount0' and 'amount1' parameters can be either a string or a number, representing the number of tokens in major units. For instance, if the deposit token is wETH, 'amount' being equal to 0.5 or '0.5' signifies 0.5 wETH. One of the 'amount' parameters must be set to zero. Use the isTokenAllowed() function to determing if a token could be deposited.

import { Web3Provider } from '@ethersproject/providers';
import { deposit, SupportedDex } from '@ichidao/ichi-vaults-sdk';

const web3Provider = new Web3Provider(YOUR_WEB3_PROVIDER);
const vaultAddress = "0x3ac9...a5f132"
const dex = SupportedDex.UniswapV3

const amount0 = 100
const amount1 = 0

const txnDetails = await deposit(
    accountAddress,
    amount0, // can be 0 when only depositing amount1
    amount1, // can be 0 when only depositing amount0
    vaultAddress,
    web3Provider,
    dex,
    1 // acceptable slippage (percents)
)

3. depositNativeToken()

param	type	default	required
accountAddress	string	-	true
amount0	string | number | BigNumber	-	true

overrides	Overrides	undefined	false

This function deposits native tokens of the chain into the vault if the vault accepts wrapped native token deposits. The 'amount0' and 'amount1' parameters can be either a string or a number, representing the number of tokens in major units. For instance, if the deposit token is wETH, 'amount' being equal to 0.5 or '0.5' signifies 0.5 wETH, and 0.5 ETH will be deposited. The other 'amount' parameter must be set to zero.

import { Web3Provider } from '@ethersproject/providers';
import { deposit, SupportedDex } from '@ichidao/ichi-vaults-sdk';

const web3Provider = new Web3Provider(YOUR_WEB3_PROVIDER);
const vaultAddress = "0x3ac9...a5f132"
const dex = SupportedDex.UniswapV3
const accountAddress = "0xaaaa...aaaaaa"

const amount0 = 100
const amount1 = 0

const txnDetails = await depositNativeToken(
    accountAddress,
    amount0, // can be 0 when only depositing amount1
    amount1, // can be 0 when only depositing amount0
    vaultAddress,
    web3Provider,

The approveVaultToken() function facilitates the approval of vault tokens for the withdrawWithSlipage() and withdrawNativeToken functions. The 'shares' parameter can be either a string or a number, representing the number of vault tokens in major units. For example, if 'shares' is equal to 0.5 or '0.5', it signifies 0.5 vault token. If the 'shares' parameter is not specified, the token will be approved for the maximum allowable amount.

import { Web3Provider } from '@ethersproject/providers';
import { approveVaultToken, SupportedDex } from '@ichidao/ichi-vaults-sdk';

const web3Provider = new Web3Provider(YOUR_WEB3_PROVIDER);
const vaultAddress = "0x3ac9...a5f132"
const accountAddress = "0xaaaa...aaaaaa"
const amount = 100
const dex = SupportedDex.UniswapV3

const txnDetails = await approveVaultToken(
    accountAddress,
    vaultAddress,
    web3Provider,
    dex,
    amount // (optional)
);

await txnDetails.wait();

// can now deposit token0

shares	string | number | BigNumber	-	true
vaultAddress	string	-	true
jsonProvider	JsonRpcProvider	-	true

This function facilitates the withdrawal of the specified amount of shares from the vault. As a result, both vault tokens are added to the user's account. The 'shares' parameter can be either a string or a number, representing the number of vault tokens to be withdrawn from the vault, specified in major units. For instance, if 'shares' is equal to 0.5 or '0.5', it signifies 0.5 vault token.

import { Web3Provider } from '@ethersproject/providers';

    vaultAddress,
    web3Provider,
    dex,
)

let shares = Number(totalUserShare) * 0.5 // 50% of user deshare balance
