What is Parakeet SDK

Parakeet Bridge provides a key missing piece of infrastructure by helping users bridge their NFTs between multiple blockchains.

With Parakeet bridge you can transfer your ERC721/ERC1155 tokens across multiple public blockchain networks in a secure, trustless & decentralized manner.

How to approve the bridge

1. Import approve function


`js
import { approve } from 'parakeet-bridge-sdk/src/';
`

2. Use inside your project. All arguments are required

`js
await approve({
srcChainId,
nftCollectionAddress,
tokenId,
provider,
account,
});
`

$3

| Argument | Type | Required | Description |
| -------------------- | :-----: | -------: | ----------------------------------------------------------------- |
| srcChainId | Integer | true | chain Id on the source chain -> chain on which the NFT is present |
| nftCollectionAddress | String | true | contract address of collection on the source chain |
| tokenId | String | true | specific token Id that you want to bridge |
| provider | Object | true | Web3Provider |
| account | String | true | account address |

How to bridge the NFT

1. Import bridge function


`js
import { bridge } from 'parakeet-bridge-sdk/src/';

2. Use inside your project. All arguments are required

`js
await bridge({
srcChainId,
dstChainId,
nftCollectionAddress,
tokenId,
provider,
account,
});
`

$3

| Argument | Type | Required | Description |
| -------------------- | :-----: | -------: | --------------------------------------------------------------------------- |

account,
dstChainId,
srcChainId,
provider,
tokenId,
nftSrcContractAddress
});
`

$3

| Argument | Type | Required | Description |
| -------------------- | :-----: | -------: | --------------------------------------------------------------------------- |

Example

$3

`js
import { approve, bridge } from 'parakeet-bridge-sdk/src/';
import { useWeb3React } from '@web3-react/core';

const useBridge = () => {
const { account, library } = useWeb3React();

// rinkeby
const srcChainId = 4;

// optimism kovan
const dstChainId = 69;

// address of the NFT collection on the source chain -> on Rinekby(in this example)
const nftCollectionAddress = '...';

// token Id owned by account
const tokenId = '...';

// provider
let provider;
// in case of ethers.js
provider = library.provider;
// in case of web3.js
provider = library.currentProvider;

const estimateFee = async () => {

try {
const estimatedFees = await estimateBridgeFees({
account,
dstChainId,
srcChainId,
provider,
tokenId,
nftSrcContractAddress
});
console.log(estimateFee)
} catch (err) {
console.error(err);
}
};

const bridgeNFT = async () => {
try {
const approveTx = await approve(
srcChainId,
nftCollectionAddress,
tokenId,
provider,
account
);

const bridgeTx = await bridge(
srcChainId,
dstChainId,
nftCollectionAddress,
tokenId,
provider,
account
);
} catch (err) {
console.log(err);
}
return { approveTx, bridgeTx };
};

return { bridgeNFT };
