.NET/Unity - Insight Indexer and Engine Wallet Integration

What's Changed

Insight Indexer .NET Integration

Insight is an extremely useful and performant tool to query blockchain data and can decorate it quite nicely too.

Did you know that vitalik, on Ethereum, Polygon and Arbitrum alone owns 7811 ERC20s, 34,362 ERC721s and 2,818 ERC1155s?
Let's go through some examples!

Instantiation

using Thirdweb.Indexer;

// Create a ThirdwebInsight instance
var insight = await ThirdwebInsight.Create(client);

Simple Args

// Setup some filters
var address = await Utils.GetAddressFromENS(client, "vitalik.eth");
var chains = new BigInteger[] { 1, 137, 42161 };

Fetching all tokens owned by a given address

// Fetch all token types
var tokens = await insight.GetTokens(address, chains);
Console.WriteLine($"ERC20 Count: {tokens.erc20Tokens.Length} | ERC721 Count: {tokens.erc721Tokens.Length} | ERC1155 Count: {tokens.erc1155Tokens.Length}");

Fetching a specific type of token owned by a given address

// Fetch ERC20s only
var erc20Tokens = await insight.GetTokens_ERC20(address, chains);
Console.WriteLine($"ERC20 Tokens: {JsonConvert.SerializeObject(erc20Tokens, Formatting.Indented)}");

// Fetch ERC721s only
var erc721Tokens = await insight.GetTokens_ERC721(address, chains);
Console.WriteLine($"ERC721 Tokens: {JsonConvert.SerializeObject(erc721Tokens, Formatting.Indented)}");

// Fetch ERC1155s only
var erc1155Tokens = await insight.GetTokens_ERC1155(address, chains);
Console.WriteLine($"ERC1155 Tokens: {JsonConvert.SerializeObject(erc1155Tokens, Formatting.Indented)}");

Fetching Events
Note: most of these parameters are optional (and some are not showcased here)

// Fetch events (great amount of optional filters available)
var events = await insight.GetEvents(
    chainIds: new BigInteger[] { 1 }, // ethereum
    contractAddress: "0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d", // bored apes
    eventSignature: "Transfer(address,address,uint256)", // transfer event
    fromTimestamp: Utils.GetUnixTimeStampNow() - 3600, // last hour
    sortBy: SortBy.TransactionIndex, // block number, block timestamp or transaction index
    sortOrder: SortOrder.Desc, // latest first
    limit: 5 // last 5 transfers
);
Console.WriteLine($"Events: {JsonConvert.SerializeObject(events, Formatting.Indented)}");

Full Insight .NET Reference

Engine Blockchain API .NET Integration

Engine is one of thirdweb's most important products. We've created an EngineWallet class that can be used as an IThirdwebWallet and as such benefits from being compatible with the entire SDK!

Usage:

// EngineWallet is compatible with IThirdwebWallet and can be used with any SDK method/extension
var engineWallet = await EngineWallet.Create(
    client: client,
    engineUrl: Environment.GetEnvironmentVariable("ENGINE_URL"),
    authToken: Environment.GetEnvironmentVariable("ENGINE_ACCESS_TOKEN"),
    walletAddress: Environment.GetEnvironmentVariable("ENGINE_BACKEND_WALLET_ADDRESS"),
    timeoutSeconds: null, // no timeout
    additionalHeaders: null // can set things like x-account-address if using basic session keys
);

// Simple self transfer
var receipt = await engineWallet.Transfer(chainId: 11155111, toAddress: await engineWallet.GetAddress(), weiAmount: 0);
Console.WriteLine($"Receipt: {receipt}");

Integrated with last December's EIP-7702 release!

Additional Changes

• Arbitrum, Arbitrum Nova and Arbitrum Sepolia gas price related methods now get shortcut early and return maxFeePerGas = maxPriorityFeePerGas = current gas price.
• Utils.GetChainMetadata chain id related variables updated from int to BigInteger.
