Blockchain Explorer Guide
How to confidently investigate, confirm, and troubleshoot stablecoin transactions across supported chains.
Why This Matters
Every stablecoin transaction—deposit or payout—touches a blockchain. Explorers are your eyes on-chain, allowing your team to:
Confirm if a transfer happened
Understand why a deposit hasn’t been credited
Catch customer mistakes early (wrong token, wrong chain, failed tx)
Backtrace issues without waiting on engineering
With Bitnob supporting multiple chains, your Ops, Finance, and Support teams need to know how to read each explorer and interpret key transaction signals correctly.
What is a Blockchain Explorer?
A blockchain explorer is a real-time search engine for blockchains. It lets you:
Look up wallet addresses
View stablecoin transfers (e.g. USDT, USDC)
See whether a transaction is confirmed
Decode failed transactions, gas used, and token details
Spot errors like wrong chain or unsupported token usage
Think of it like your Stripe dashboard’s activity log—but public, transparent, and immutable.
How to Investigate a Transaction
Let’s say a customer says:
“I sent $100 USDT to my deposit address, but I haven’t received anything.”
Your process:
Step 1: Ask for the Transaction Hash (txHash) Tell them:
“Please share the transaction hash from your wallet or exchange. It’s a long string like 0xabc... or TXabc... depending on the chain you used.”
Step 2: Paste it into the Right Explorer
| Chain | Explorer |
|---|---|
| Ethereum | https://etherscan.io |
| BSC | https://bscscan.com |
| Polygon | https://polygonscan.com |
| Tron | https://tronscan.org |
| Solana | https://solscan.io |
| TON | https://tonscan.org |
If you don’t know which chain they used, you can guess from the txHash format:
0x... → Ethereum, BSC, Polygon
TX... → Tron
Base58 → Solana
EQ... or base64 → TON
What to Look For
| Section | What to Look For | Why It’s Important |
|---|---|---|
| Status | Success or Confirmed | Tells you the tx was accepted by the chain |
| Confirmations | 15 (ETH, BSC), 19 (Tron), 1 (Solana) | Less than required = Bitnob won’t credit it |
| To Address | Must match the Bitnob deposit address | If wrong, funds are unrecoverable |
| Token Used | Must be real USDT/USDC, not a fake copy | Check contract address |
| Token Transfer | Found in a Token tab (ERC-20, BEP-20, SPL) | Stablecoin transfers live here |
| Amount | Match against what was expected (e.g., $100) | Validate value integrity |
Explorer Examples
Ethereum / BSC / Polygon
Use “ERC-20 Token Txns” or “BEP-20 Token Txns” tab
Confirm USDT contract matches official one
USDT (BSC): 0x55d398326f99059ff775485246999027b3197955
Look at gas price if tx failed Reverts often say why: “out of gas”, “invalid opcode”
Tron
Use Tronscan.org Check “TRC-20 Transfer” tab Confirm 19 confirmations Address format: starts with T
Watch out for:
Token sent using TRX instead of USDT Wrong memo if customer used an exchange
Solana
Use Solscan.io Paste the address or txHash Confirm token is USDT in the “Token Transfers” list Finality is almost instant (1 confirmation)
Teach Through Examples
✅ Confirmed Deposit (Ethereum)
Status: Success
To: Bitnob-issued address
Confirmations: 18
Token: USDT
Contract: Matches official USDT ERC-20 → ✅ Webhook should have been emitted, wallet should be credited.
❌ Wrong Chain Customer was given a Tron USDT address (TRC-20), but they sent via Ethereum (ERC-20).
How to detect:
Their txHash starts with 0x...
It only shows activity on etherscan.io, nothing on Tronscan
Bitnob didn’t detect anything → the address wasn’t valid on Ethereum
Response:
"You sent USDT using Ethereum, but the address we gave you only works for USDT on Tron. These are separate networks. Unfortunately, the funds may be lost."
⚠️ Stuck Pending Payout A transfer from Bitnob to an external wallet has been stuck in pending for 20+ minutes.
Steps:
Search for txHash on explorer
Check:
Is the tx still pending? → network congestion
Did it fail? → out of gas, contract revert
Was it never broadcast? → contact engineering
Retry or escalate via reference ID and chain
Visual Cheatsheet
| Chain | Address Format | txHash Format | Token Tab Name |
|---|---|---|---|
| Ethereum | 0x... | 0x... | ERC-20 Token Txns |
| BSC | 0x... | 0x... | BEP-20 Token Txns |
| Polygon | 0x... | 0x... | ERC-20 Token Txns |
| Tron | T... | TX... | TRC-20 Transfers |
| Solana | base58 | base58 | Token Transfers |
| TON | EQ..., hex | base64 or hex | Jetton Activity |
Bonus Tips for Ops Dashboards
Include "View on Explorer" button in every transaction record
Show a “Copy txHash” shortcut
Auto-detect incorrect confirmations and flag them
Flag tokens that don’t match official contracts
Add internal note: Explorer confidence: ✅ Confirmed / ⚠️ Not enough confirmations / ❌ Wrong chain
