Hi all,
After another week+ of working on https://adacheck.io, I’m happy to show you a number of new features and improvements.
1 - Transaction listing is now fully human readable, showing each transaction as In or Out (i.e. deposit or withdrawal). You now see the actual in and out of transaction amounts, just like a bank statement! This was actually complicated to do in Cardano, but is way more usable/readable vs. the default results from the blockchain.
Here’s how it looks now on AdaCheck:
and the same address shown on CardanoExplorer so you can see the difference in terms of how transactions are displayed:
1A - After loading an address, you can then search by transaction id or by amount of the transaction. Pagination also added to control how many transactions shown per page.
Note - you can view yourself the difference using these 2 links, which will show the identical Ada address to compare:
2 - Latest Ada price is now shown at the top (thanks to CoinMarketCap.com) - the idea is if you are about to make a transaction, we want to inform you of the current rate.
3 - ETH support added! Long term Ada will interact with all the major currencies, (and hopefully lure away their users :), plus it’s always possible someone may check an Ada address with an ETH address instead.
Thus, AdaCheck will now auto-detect between valid Ada address and valid ETH, and if ETH address, it will provide the same info regarding balance, validity, transaction history (thanks to EtherScan.io for hooking us up!):
4 - Transaction notification: We were ready to code this feature where you could register to be notified of incoming or outgoing transactions to your address.
However, the socket support offered by Cardano to do this is not working (errs out connecting). We believe the same errors are happening in CardanoExplorer so it seems intrinsic to the current state of the blockchain and notification support at this time. We’ll attempt to offer it in the future.
If you see additional features you’d like to be added to https://AdaCheck.io, pls feel free to post and let us know! Otherwise,starting tomorrow we begin work on a dedicated Ada decentralized exchange to help make Ada more easily available to the world
