## Gnosis APIs

Gnosis APis are used to create transactions on the multisig and fetch transactions.

To use Gnosis

### Initialize gnosis:

```sh
const gnosis = new Gnosis(provider: Web3Provider, chaindId: number)
```

### To create a single gnosis transaction

```sh
const result = await gnosis.createSingleGnosisTx(receiverAddress: string, value: string,
safeAddress: string, senderAddress: string)
```

> Param 1: `safeAddress` Gnosis safe address.
> Param 2: `receiverAddress` Wallet address of the user whom the funds is being sent.
> Param 3: `value` ETH value in wei.
> Param 4: `senderAddress` Waller address of the sender

### To create a batch gnosis transaction

```sh
const result = await gnosis.createBatchGnosisTx(safeAddress: string, receiverAddresses: string[],
value: string, senderAddress: string)
```

> Param 1: `safeAddress` Gnosis safe address.
> Param 2: `receiverAddresses` Wallet addresses of the users whom the funds is being sent.
> Param 3: `value` ETH value in wei.
> Param 4: `senderAddress` Waller address of the sender

### To get pending transactions for a safe

```sh
const result = await gnosis.getPendingTransactions(safeAddress: string)
```

> Param 1: `safeAddress` Gnosis safe address.

Example

```sh
const result = await gnosis.getPendingTransactions("0xE666431e8Ba10B17D296aB16A4FF8d9A552eb488")
```

### To get past / executed transactions for a safe

```sh
const result = await gnosis.getExecutedTransactions(safeAddress: string)
```

> Param 1: `safeAddress` Gnosis safe address.

Example

```sh
const result = await gnosis.getExecutedTransactions("0xE666431e8Ba10B17D296aB16A4FF8d9A552eb488")
```

### To get transactions details, status of a transactions for a safe transaction hash

```sh
const result = await gnosis.getTransactionDetails(safeTxHash: string)
```

> Param 1: `safeTxHash` Transaction hash of a particular safe transaction.

Example

```sh
const result = await gnosis.getTransactionDetails("0x4a429ae97dd5bac92e9eef8e28fba94cf8813474c485228e58d81f04c332c399")
```

### To connect a gnosis safe

```sh
const result = await gnosis.connectGnosis(userAddress: string)
```

> Param 1: `userAddress` User address

This will return the safes for which user is an owner and also list of all other owners for a safe

Example

```sh
const result = await gnosis.gnosisConnect("0x4a429ae97dd5bac92e9eef8e28fba94cf8813474c485228e58d81f04c332c399")
```

## NFT Profile APIs

NFT Profile APIs are used to fetch the NFTs owned by the user on ETH and Polygon which can later be set as profile photos

### Initialize NFT Profile Photos:

```sh
const nftProfile = new NFTProfile()
```

### To get ETH based NFTs

```sh
const ethNFTs = await nftProfile.getEthProfilePPs(ethUserAddress: string)
```

> Param 1: `ethUserAddress` Wallet Address of the user.

Example

```sh
const ethNFTs = await nftProfile.getEthProfilePPs(0xB1BFB38a527D05442D48068ca9798FD3E5d6ce0F)
```

### To get Polygon based NFTs

```sh
const polygonNFTs = await nftProfile.getMaticProfilePPs(maticUserAddress: string)
```

> Param 1: `maticUserAddress` Wallet Address of the user.

---

## Lit Protocol APIs

Lit Protocol APIs are used to for token gating

To use Lit Protocol

### Initialize Lit Protocol:

```sh
const litProtocol = new LitProtocol()
```

### To create a Lit protocol gating

```sh
const tokenGating = await litProtocol.init(
    chain: string,
    contractAddress: string,
    typeOfGating: TokenGatingType,
    baseUrl: string,
    path: string,
    memberId: string,
    tokenId?: string
)
```

> Param 1: `chain` The chain on which the Token Gating will be created. Refer the list of chains below the example.
> Param 2: `contractAddress` Contract Address of the Token.
> Param 3: `typeOfGating` Enum value of which type of Gating. Refer the enum list below the example.
> Param 4: `baseUrl` Url of the url of frontend.
> Param 5: `path` The Path that requires the token gating.
> Param 6: `memberId` Member UUID that is being authenticated.
> Param 7: `tokenId` Token ID of a NFT for verification.

> Returns: `jwt` JWT token can be set on cookies or anything on the frontend and needs to be sent to SDK for verification

Example

```sh
const tokenGating = await litProtocol.init(
    chain: "rinkeby",
    contractAddress: "0xB1BFB38a527D05442D48068ca9798FD3E5d6ce0F",
    typeOfGating: 0,
    baseUrl: "http://samudai.xyz",

  ERC20,
  ERC721,
  ERC1155,
}

ERC20 = 0
ERC721 = 1
ERC1155 = 2
```

### To verify the user

```sh

```sh
const result = siwe.walletSignIn(domain: string)
```

> Param 1: `domain` URL of the frontend
