Im building a small exchange like sidesift.ai where users can exchange crypto fast and with no KYC.

When a user send crypto to the deposit adress, they have to get notification that the crypto they have sent is confirmed on teh network.

I will have like 50 different coins in total.
USDT, BTC, ETH, SOLANA, ADA, FTM, and so.
Probobly the most popular ones.

Total users per day will be very low at the beginning, probobly like 1-10 users a day.

Anyone knows any good way of doing this?
Also good if its a free API.
I have seen stuf that goes for like 150 usd but im not paying that.

Lincolnbrothers io airdrop will be launched in March and is available soon.

Dont miss out this chance to be a part of this project.

Deploying smart contracts on the mainnet is a more expensive operation than deploying tests on the testnet. This is because developers have to pay gas fees before they can deploy their smart contracts on the mainnet, and these gas fees cost some ETHs.
You wouldn’t want to spend real coins when you’re just testing your smart contracts. That’s where testnets come in. Testnets provide free cryptocurrency you can use to pay for gas fees. Since this free cryptocurrency has no value, it can’t be used in the mainnet.
