Crypto Tools Directory: Check Transactions, Addresses, Gas Fees, Prices & Security

The most useful Crypto tools for beginners — check on-chain transactions, wallet addresses, USDT transfer status, gas fees, prices, market cap, token contracts, and DeFi/RWA data.

Each tool tells youwhen to use it and what it can check.

What do you want to check?

USDT sent but not arrived

Check the on-chain status on TRC20, ERC20 and BEP20 to see whether the issue is with the sender, the network or the receiver.

You already have a TxID

Open the right block explorer and check the status, confirmations and addresses.

Check a wallet address

View balances, token holdings and history for a public address — no wallet connection needed.

Are gas fees high right now?

See current fees and congestion on Ethereum, Bitcoin and other networks.

Check prices & market cap

Quickly see the price, market cap and volume of BTC, ETH, USDT and more.

Check a token contract

Before adding a token or using a DEX, verify the network, contract address and official info.

Review wallet approvals

See which contracts are approved, how much, and whether to revoke them.

Check DeFi / RWA data

See DeFi TVL, stablecoins, and RWA data such as tokenized Treasuries.

Security note: Legitimate market sites and block explorers will never ask for your seed phrase or private key. Close any site that asks for a private key, a verification code or your exchange password.

FAQ

Which tool should I use to check a USDT transfer?

Start with the network. Use Tronscan for TRC20, Etherscan for ERC20, BscScan for BEP20, and Solscan for Solana. If you are not sure which network you used, check your exchange withdrawal record or wallet transaction details first.

The explorer shows Success — why has it not arrived?

On-chain success only means the blockchain transaction is complete. The receiving platform may still need more confirmations, internal crediting or risk review. So: on-chain success does not mean it is credited by the receiving platform.

Is it safe to check a wallet address?

Yes. Checking a public address does not require connecting a wallet and does not give anyone control. Just never share your seed phrase, private key or signature permissions.

Should I use CoinGecko or CoinMarketCap?

Both work for prices, market cap and basic market data. For everyday lookups there is no need to insist on one.

After revoking an approval, am I definitely safe?

Not necessarily. Revoking solves the smart-contract permission issue. If your seed phrase or private key has already leaked, you still need to check whether the wallet itself is safe to keep using.

Before using third-party tools

Third-party sites are operated by their own providers. Check the domain before visiting, and never enter your seed phrase, private key, exchange password or verification codes.
