100% Free ToolsNo Data SellingEvery Amount HelpsStudent Run
I'm a 22-year-old student, and nttech.org started as a small side project I built to solve real, everyday problems with simple tools — nothing fancy, no data tracking, no hidden="hidden" agenda. Just honest tools that actually help people.
Right now, we have around 6,500 to 28,000 users every month, which honestly still feels surreal to me. But behind the scenes, things have gotten tough. We've been working on a new AI-based project for a while now, and that's taken up most of our time and resources. As a result, we haven't released new tools in a long time — and now, we're completely out of funds.
If we can't manage support soon, nttech.org might have to shut down within the next 50 days.
I never wanted to fill this site with intrusive ads or sell anyone's data just to keep it running — that goes against everything this project stands for. So instead, I'm just being honest with you.
If you've ever found one of our tools useful, even a small donation would genuinely mean a lot. Whether it's $1 or 1 cent — it all helps, and it tells me this project is worth continuing.
Thank you for reading this, for using what we've built, and for considering supporting a student trying to keep something good alive.

Ways to Donate
Donate with Crypto
Choose the network your wallet supports. Every donation, big or small, goes straight into keeping the site online.
EVM
EVM Networks
One address, many chains
This single address works on Ethereum and other EVM-compatible chains, so you can use whichever network has the lowest fees for you. Send the native coin or tokens like USDT and USDC.
Send SUI or tokens that live on the Sui network, such as USDC on Sui. Sui addresses also start with 0x, but they are not EVM addresses, so please use a Sui wallet to send.

Before You Send
Three Quick Tips
Crypto transfers can't be reversed, so a little care goes a long way.
01🔗
Match the network
An EVM address only works on EVM chains, Solana on Solana, and Sui on Sui. Please double-check before you confirm.
02📋
Copy, don't type
Use the copy button and compare the first and last few characters in your wallet app before sending.
03🧪
Start small if unsure
New to a network? A tiny test transfer is a perfectly good way to make sure everything works.
Donations are completely voluntary and non-refundable. Please only send funds you're comfortable donating. If you have any questions, we're always happy to help at info@nttech.org.
FAQ
Frequently Asked Questions
Which network should I choose?
Whichever your wallet already supports. If you use MetaMask, Trust Wallet or a similar wallet on Ethereum, BNB Chain, Polygon, Base and so on, pick the EVM address. Phantom users can use the Solana address, and Sui Wallet users can use the Sui address.
Can I really donate a very small amount?
Yes, absolutely. Every little bit helps and means a lot to us. Just keep in mind that network fees can be higher than a tiny donation on some chains, so Solana, Sui, Base or Polygon are usually the cheapest options.
Is my donation private?
Blockchain transactions are public by nature, so your wallet address can be seen on-chain. On our side, we don't collect, store or sell any personal information, just like with our tools.
Can't donate right now? That's completely okay.
Using our tools, sharing the site with a friend, or sending us an idea for a new tool helps just as much. Thank you for being here.
