How to Track Tether USDT TRC20 Transactions Using Bitquery API?

Tracking USDT transactions can be a difficult task due to the decentralized nature of blockchain technology. All cryptocurrency transactions are recorded on the blockchain, providing transparency while also maintaining a sense of anonymity.

This means all wallet addresses are anonymous, making it difficult to link them to actual identities.

However, with blockchain explorers like Bitquery, we can easily search for a specific wallet address and view its entire transaction history.

Fetching Transactions by Wallet Address

Consider a practical scenario where you need to monitor a specific wallet for Tether USDT TRC20 transactions. Let's break down how you can analyze and interpret the data effectively.

Transaction Volume: By watching daily transfers of USDT, we can spot patterns and unusual changes in transaction levels. Big spikes in activity, like sudden increases in transactions, often mean important events such as large trades, market shifts, or specific wallet actions.

For example, let's look at the In/Outbound transfer of the wallet address:TL98FzQWz35qsMP93QcXk1vAUfTpqeE3kU from June 21st to June 27th, 2024.

On June 27th, there was a significant rise in activity: 25 deposits and 14 withdrawals. This surge suggests major financial movements, possibly involving large trades or significant payments.

Wallet Activity Insights: By examining USDT TRC20 transactions flowing in and out of a wallet, we can understand its behavior.

This includes how often and how much it transacts, and whether it is mainly accumulating or distributing assets.

Let's look at wallet TL98FzQWz35qsMP93QcXk1vAUfTpqeE3kU.

When we look at its transactions, we see significant movements of USDT TRC20 tokens. These large inflows and outflows suggest that money is being moved around, most likely for storage and accumulation.

Account Management: Analyzing the inflow and outflow of funds in a wallet can give us insights into how the wallet owner manages their money.

Inflow: Regular large deposits suggest the owner is making consistent investments.
Outflow: Significant withdrawals could mean the owner is transferring funds to other wallets, or making payments.

Let's look at wallet TL98FzQWz35qsMP93QcXk1vAUfTpqeE3kU.

This wallet shows regular inflows which suggests the owner is making consistent investments. The significant outflows indicate regular spending or transfers to other wallets. By examining these transactions, we can see that the owner is maintaining a balanced financial state.

Overall, these observations suggest that the wallet owner is in good financial health by effectively managing their expenses and investments.

By collecting and studying data from many wallets and transactions on the Tron blockchain, we can understand overall market trends and activity. This helps us identify important participants, liquidity sources, and major market changes.

A Hacker's Guide to ETHIndia 2023

Nitin Jakhar — Mon, 27 Nov 2023 07:04:29 +0000

Hola Hackers!!, taking place from December 8-10, 2023, ETH India 2023 Hackathon will gather thousands of participants who will compete for over millions in bounties and prizes, as well as up to millions in investment capital.
Evolving beyond a once-a-year event, ETHIndia will function as an incubator and launchpad to create year-round support for early-stage blockchain projects.

So being the biggest Ethereum Hackathon on the face of the earth, some confusions seem to be natural but worry not we'll get you through to some of the most established projects in Web3 space and how to utilize them to get your way to the delicious bounties and grants, but more than grants team-spirit is required and if you don't have the team there are thousands like you, so buckle up and find a team-mate directly in the hackathon.

Head onto the ETHIndia website to register now and read below more a less melodramatic journey

What Projects can be built?
The essence of Ethereum Hackathons is to build anything you like, may it be a web3 protocol or just a simple tuning software but it always helps to go on through the list of Sponsors and build your project around their Protocols and offerings to get that juicy prizes and recognition, you have been waiting for.
Below is the list of sponsors that you can incorporate in your own projects along with how to use their services which range from every aspect of development including every tool that you need and Bitquery for your data needs.

Defi - Build using 1inch
1inch is an OG in the defi space, it is your gateway to seamless crypto swaps and was founded by hackers in ETHIndia 2019 only, so whether you want Wallet and dApp integrations or make protocols for lending, borrowing, margin trading, 1inch has got your back.
Let's talk about the core Protocols offered by 1inch

Aggregation Protocol V5 - The blue-chip offering of 1inch which provides liquidity across multiple protocols, chains, and liquidity sources.

Limit Order Protocol V3 - Don't like the current prices of tokens across any liquidity source, put limit orders of the price you want, that too on-chain.

Spot Price Aggregator - Want to exact and non-vulnerable price data across using multiple Oracle services in 1 click, 1inch got you. Just head over to this contract

Fusion Mode - Tired of being front-run by the annoying MEV bots and want gas-less transactions, build powerful Dapps using this SDK

Those are the core offerings of 1inch but if you need easily indexed data from over 40 chains that can help you build more robust Dapps and APIs, head over to Bitquery.
For Example, if you got 1inch integrated into your next-gen Defi App but are confused about what the lending and borrowing rates are for different protocols over different chains, write a graphQL query to get exactly what you need or hover over Bitquery Explorer to get the current and historical gas price raw indexed data on Ethereum chain.
Just like this query, provides you with the DAI's average liquidity Rate, Stable Borrow Rate, and Variable Borrow Rate described in the graph below

L2's to build upon the get the cheap, yum yum gas fee

Now, we'll talk about the hottest L2s in the space now to build your Dapp upon

Polygon - It all began in the early days, when the founders founded their tribe at ETHIndia '18, laying the roots for the Indian Web3 landscape.

Their mission? Enhance Ethereum's limitations and create a seamless, interconnected ecosystem.
Fast forward to 2023, Polygon metamorphosed, releasing its grand vision — Polygon 2.0, the roadmap to sculpting the Value Layer of the Internet.
The proof is in the pudding: Polygon unveiled Polygon Hermez, a zk-rollup scaling marvel that revolutionized transaction security and speed.

One of their standout achievements is the Polygon Chain Development Kit (CDK). This powerful tool simplifies the creation of ZK-powered L2 chains on Ethereum.
Once again to build a robust Dapp, you need Robust Data. Again Bitquery is to rescue, with an explorer explicitly made for Polygon with all the APIs you'll ever need for Polygon data ranging from raw indexed bock data to Dex Trades API to Miner Distribution APIs, it's all there.

Scroll ZKP - Scroll is the first fully EVM-compatible ZK-Rollup!!, what does that mean dumbo? It means that the code written on Scroll is directly converted in EVM bytecode rather than converted into another gibberish before being compatible with EVM. So now you can write Solidity Dapps without changing their source code by a fraction of a hair. Still puzzled head over to the official documentation

Backed by external audits & grounded in battle-tested cryptographic libraries, they emphasize a robust security posture.
After 15 months of testnets, 450K+ smart contracts deployed, 90M+ transactions, & 280K ZK proofs, Scroll officially launched on the mainnet in October '23!

Scroll believes in meeting developers and users where they are. They actively cultivate transformative ideas globally, fostering a diverse community that's shaping the future of Ethereum.

Base L2 - Yup, another one of the bigshots incubated by Coinbase and progressively decentralizing by each day, Base is a secure, low-cost, builder-friendly Ethereum L2 built to bring the next billion users on-chain.

You can use it interoperably with Coinbase Exchange to make DeFi-CeFi Dapp incorporating best of the both worlds.
Are you an EIP geek or tired of using the gen-old EOA? Use pre-made ERC4337(Account Abstraction) APIs, gasless transaction API, easy fiat onramps, and more.
Whoa, that was too many to choose from huh, not the next section is critical for any Dapp to be truly decentralized, the big boss itself - decentralized storage

Decentralized Storage Providers
Whether you are building a game, a multi-chain trading app, or even some crazy analytic Dapp, you'll need storage. Welcome to open decentralized storage services

Filecoin - Filecoin is building open services for data. Their vision revolves around the three pillars: storage, retrieval, and data transformation. The goal is to form a credible alternative to the legacy cloud infrastructure, both in scale and suite of data services.

The launch of FVM earlier this year represents a significant milestone, enabling developers to shape the future of open data economy applications.

Now, you can build smart contracts, Data DAOs, and more on Filecoin's vast decentralized storage network!
So how does it work - it is a peer-to-peer network that stores files, with built-in economic incentives and cryptography to ensure files are stored reliably over time and is built on top of IPFS protocol.

Filecoin also supports a wide range of formats of data, including audio and video files.
It's okay if you don't understand how it works, cause the next protocol solves that exact problem.

Once again, head over to Bitquery's Filecoin Explorer to get in-depth data on miners, validators, and your data storage transactions.
If you are just like a lost baby girl not able to find the validator suited for your data needs, see all their on-chain Summary

Lighthouse - It is a perpetual file storage protocol that allows you to pay once for your files and store them long-term.

The aim is to move users from a rent-based cost model where they rent their files on cloud storage to a perpetual storage model. It is built on IPFS and Filecoin, with smart contracts to be deployed on multiple chains like FVM, Optimism, Polygon, Solana, etc.
It uses the miner network and storage capacity of the Filecoin network and IPFS content-addressing system.

So, forget about the recurring payments to Filecoin Validators, forget about the its-bits of managing the data bots. Here is the link for a great tutorial for storing the metadata of Minting NFT on multiple EVM chains at once!!

Last one I promise, if you don't like EVM, how about another L1 with its unique benefits

Celo - It is a mobile-first L1 chain with low-cost, multi-currency gas fees and an ultralight client for your ultralight Dapps.
Celo was designed to enable a new universe of financial solutions accessible for mobile users, creating a global financial ecosystem where an end-user can onboard into the Celo ecosystem with just a mobile number.

If you want your Dapp to scale in a market such as India, you can make your payments as easy as sending a text. Head over to Developer docs and see it yourself.
Still in doubt about choosing Celo over Ethereum head over to the gas analytics data over to bitquery Celo Explorer to see the difference as depicted in the graph below with average transaction cost costing as less as $0.00075

Time to Wrap it Up!
No matter if you’re new to blockchain or a pro, it’s like a playground for everyone! The worst thing that can happen? You create something cool, make friends, and have a blast. But the best part is way cooler! Imagine building something amazing, winning cash, getting funding, making tons of new friends, AND having an absolute blast! 🎉

How do you find your wallet address on the Ethereum blockchain?

If you want to view complete information about a wallet address, including transactions, trades, and everything, there's a simple way. Use https://explorer.bitquery.io/ and type the address in the search bar, you will see the complete record of the address on chain.

How can you identify an Ethereum scam by looking at the wallet address?

Use data providers that have indexed blockchain data. Bitquery for example, labels most of the fraudulent addresses. For example, the following address has a label "Upbit Hacker 1" which tells us that the address was one of the hackers that stole funds from Upbit Exchange.

How can you determine what Ethereum wallet is being used based on a public address?

If you have their address, then go to a blockchain explorer and paste the address. You can see the historical and real-time transactions, trades, and wallet balance

How many Ethereum Addresses are there?

To get the count of addresses that are active right now, you need to use any indexed data provider that gives you Ethereum stats for example, through REST APIs or JSON-RPC.

At the time of writing, we use this graphQL query to find the number of addresses today to be 766346. You can run this query for any period of time to see the active addresses.

query MyQuery {
  ethereum(network: ethereum) {
    activeAddresses(date: {is: "2023-10-12"}) {
      count(uniq: address)
    }
  }
}

I would like to get all transactions given an address

Use this query which gets all transactions where the address is the sender. There is no limit on how much data you can get.

query ($network: EthereumNetwork!, $address: String!, $from: ISO8601DateTime, $till: ISO8601DateTime) {
  ethereum(network: $network) {
    transactions(
      options: {desc: "block.timestamp.time", limit: 10}
      date: {since: $from, till: $till}
      txSender: {is: $address}
    ) {
      block {
        timestamp {
          time(format: "%Y-%m-%d %H:%M:%S")
        }
        height
      }
      success
      address: to {
        address
        annotation
      }
      gasValue
      gas_value_usd: gasValue(in: USD)
      gasCurrency {
        symbol
      }
      hash
    }
  }
}
{
  "network": "ethereum",
  "address": "0x28c6c06298d514db089934071355e5743bf21d60",

How to Track liquidity for token pairs on Uniswap

Nikhil — Tue, 05 Sep 2023 09:30:00 +0000

Introduction

Today we will explore different aspects of the liquidity pools of any token pair on Uniswap. Uniswap is the most popular dapp in the crypto ecosystem; it is a decentralized exchange (DEX) that allows you to trade tokens on a blockchain. Out of the different types of DEX, Uniswap is called AMM (Automated money market), which relies on the concept of liquidity pools. Let’s refresh on liquidity pools and then explore data using Bitquery V2 APIs.

Our V2 APIs allow us to access blockchain data in real-time using GraphQL subscriptions. You can try out V2 APIs here

Understanding Token-Pair Liquidity

There are different types of DEX, which you can divide mainly into AMM DEX and Order Book DEX. An AMM DEX like Uniswap, Sushiswap, etc. relies on algorithmic pricing and liquidity pools, while an order book DEX matches buyers and sellers directly based on their submitted orders.

Liquidity, in the context of Uniswap and similar AMM DEXs, refers to the availability of tokens in liquidity pools that facilitate trades. The pools are created by liquidity providers, who provide tokens to liquidity pools in exchange for earning part of trading fees. The depth of liquidity pools plays an important role in determining how easily traders can execute trades without causing significant fluctuations in market prices.

Now that we have clarified what liquidity pools are and how they affect DEX working, let’s see how to fetch data using the DEX API.

Get All Liquidity Pools For a Token

As anyone can create a liquidity pool for any token, there will be many pools for a single token, so let’s try to fetch a list of all the pools.

In this query, we will be fetching a list of liquidity pools created for USDT, for which we need to set buy currency to the address of USDT token.
