The token data is complicated?
Don't worry, we'll take care of it simply.
Easily browse wallets and token transfers, and ERC-20 token details with BLOCKSDK's token API. It's possible without separate indexing!
Billions of indexed data
Billions of logs, transactions, and smart contracts have already been indexed, so you don't have to.
Save more than a thousand hours
Time is an asset. We handle complicated tasks, so you focus on your customers.
Single Request
Eliminate complexity with just one request for the data you want.
No experience required.
We help you easily get the data you need and do the work you want.
I focused all the token information
I needed on one location.
There is no easy way to extract token data from a blockchain. Manual collection requires a complex process of scraping, storing, and decoding millions of blocks and billions of logs.
Token Metadata
You can easily find details of ERC-20 tokens. You can search by contract address or token symbol.

Data on all EVM-based blockchain tokens such as ERC-20-based
Uniswap, USDT, and USDC have been indexed.
SDKs based
On various languages are supported.
We offer a variety of sample codes, including sample wallets and NFT markets. Use our SDK to navigate the blockchain with concise code and get additional information with industry-leading documents!
const BLOCKSDK = require("blocksdk-js");
const client = new BLOCKSDK(
"Node_RPC_TOKEN",
"https://mainnet-api.blocksdk.com"
);
client.ethereum.GetTokenInfo({
"contract_address" : "ERC20 Token Address",
})
.then(r => console.log(r));
client.ethereum.GetTokenBalance({
"contract_address" : "ERC20 Token Address",
"from_address" : "Wallet Address"
})
.then(r => console.log(r));
DeFi, wallet, token exchange
Offering portfolios, balances, wallets, smart contract-specific transaction information, and detailed transmission records, including ERC-20 token data, the Token API boasts extremely fast performance.
Real Asset Linked Token (STO)
Want to restrict access to certain websites with real asset-based token (STO) ownership? Check your STO ownership and status with a simple API. Available on all EVM-based blockchain networks.
