BSCTrace review: NodeReal’s BNB explorer and the free API behind it

BSCTrace is a BNB Smart Chain block explorer built by NodeReal, the company behind the MegaNode node service. It lets you search blocks, transactions, addresses, tokens and .bnb names, verify contracts and follow validators — and its data is available to developers through a free MegaNode API plan with 10 million compute units a month.

That last part is why BSCTrace suddenly matters to far more people than it did two years ago. It sits at number two in our BNB explorer ranking with a score of 9.0, just behind BscScan. This review covers what the explorer looks like in daily use, what the API really gives you for free, and when it makes sense to switch.

What is BSCTrace, and who is NodeReal?

NodeReal is a blockchain infrastructure provider with deep roots in the BNB Chain ecosystem. Its main product, MegaNode, sells RPC access and indexed data APIs for BNB Smart Chain, opBNB, Ethereum and other networks. NodeReal also runs opBNBScan, the explorer for BNB Chain’s layer 2, which we cover on our opBNB and Greenfield explorers page.

BSCTrace is the showcase of that stack. Instead of maintaining a completely separate backend, the explorer reads its data through MegaNode’s own services — the same nodes and enhanced APIs you can call with a key. The practical upshot: if a page works on BSCTrace, the data behind it is something you can usually fetch programmatically too. That is a meaningful difference from explorers whose richest data never leaves the website.

Why BSCTrace matters in 2026: the BscScan API change

In December 2025 the standalone BscScan API was retired and replaced by Etherscan API V2. One key now covers 60+ chains, which sounds convenient, but Etherscan’s supported-chains table lists BNB Smart Chain mainnet and testnet as paid tier only. Thousands of small projects — portfolio trackers, Telegram bots, school assignments, accounting scripts — lost their free data source overnight.

BNB Chain answered with an official blog post, the Migration Guide: BscScan API to BSCTrace API via MegaNode. It walks through the differences (JSON-RPC 2.0 instead of REST, key in the URL path instead of a query parameter) and maps old calls to new ones: module=account&action=balance becomes eth_getBalance, the proxy calls become their eth_* equivalents, and txlist becomes the enhanced method nr_getAssetTransfers. When the chain’s own team publishes a migration path, it is about as close to an official endorsement as an independent explorer gets. Our BscScan review covers the other side of that story.

BSCTrace explorer: interface walk-through

First impression: calm. BSCTrace has a light, uncluttered layout with far fewer banners than BscScan, and pages load quickly even on a mid-range phone. If you know Etherscan-style explorers, you will find everything where you expect it.

Search, including SPACE ID .bnb names

The search bar takes a block number, transaction hash, address or token — and domain names from SPACE ID, the naming service behind .bnb addresses. Type a name like something.bnb and BSCTrace resolves it to the underlying 0x address. It is a small touch, but useful when someone sends you a name instead of an address; just remember that anyone can register a look-alike name, so confirm the resolved address before sending funds.

The menus: Blockchain, Tokens, Validators, Verify Contract, Developer APIs, BNB City

Blockchain collects the core lists: blocks, transactions, pending transactions, internal transactions, verified contracts, charts and a gas tracker. Tokens splits into BEP-20, BEP-721 and BEP-1155 lists and transfer feeds. Validators opens the validator dashboard described below. Verify Contract supports the usual methods — single file, multi-part imports and standard JSON input — with compiler version, optimisation runs, EVM version and licence settings. Developer APIs leads to MegaNode, where you create keys. And BNB City is the playful one: a real-time animated visualisation of chain activity, with blocks, TPS and gas rendered as a living city. It will not help you debug a failed swap, but it is a nice way to show a newcomer that a blockchain is a moving thing.

Transaction and address pages

A transaction page shows status, block, timestamp, from/to, value, fee, gas price and decoded BEP-20 token transfers, with tabs for logs and internal transactions. Address pages show the BNB balance, token holdings and tabs for transactions, internal transactions and BEP-20, BEP-721 and BEP-1155 transfers. Contract addresses add code, Read Contract and Write Contract, plus proxy variants for upgradeable contracts. You can download transaction data as CSV, though very large ranges may time out — the site itself suggests picking a smaller date range. For a field-by-field explanation of what you are looking at, see our guide to reading a BSC transaction.

Token pages cover total supply, holders, transfers, price and market cap where available, with a holder distribution view. What you will miss compared with BscScan is the density of name tags: BSCTrace labels major entities, but BscScan’s years of accumulated community and project submissions still give it more context on who is behind an address.

Validators, voting power and block rewards

This is where BSCTrace is genuinely better than most explorers. The homepage shows the latest block, the number of active validators (45 at the time of writing: 21 in the “Cabinet” and 24 “Candidates”) and total voting power, meaning the BNB staked behind validators — around 25 million BNB when we checked. The latest-blocks list names the validator that produced each block, such as Figment, together with the block reward.

The Validators page goes further, listing each validator with its voting power, commission and status. If you stake BNB, or you are simply curious how BNB Smart Chain’s proof-of-staked-authority works in practice — 45 elected validators, 21 of which produce blocks in each epoch — this is one of the clearest views available. The underlying rules are documented in BNB Chain’s validator overview.

MegaNode API: the free plan in practice

To use the API you create a NodeReal account, open the MegaNode dashboard and generate a key. Requests go to https://bsc-mainnet.nodereal.io/v1/<API_KEY> as standard JSON-RPC 2.0, so any Ethereum library — ethers.js, viem, web3.py — works without special adapters. Testnet has its own endpoint with the same key.

Ten million compute units sounds abstract, so think of it this way: simple reads like eth_blockNumber or eth_getBalance are cheap, while indexed history queries cost noticeably more. For a hobby bot, a wallet dashboard for a few hundred users or a research notebook, the free plan is comfortable. For a production app polling thousands of addresses, budget for Growth. The 150 CUPS limit (compute units per second) matters more than the monthly total if your app is bursty — batch requests and cache aggressively. NodeReal’s documentation lists the CU cost of every method and which features each plan includes.

Enhanced APIs: nr_getAssetTransfers, nr_getTokenHoldings and friends

Plain RPC can tell you a balance, but not “every token this wallet ever received”. That needs an index, and MegaNode’s enhanced API is where NodeReal replaces the old BscScan account endpoints. The methods we found most useful, verified against NodeReal’s API reference:

• nr_getAssetTransfers — transfer history filtered by category (external for BNB, internal, 20, 721, 1155), addresses and block range, with up to 1,000 results per page and a pageKey for pagination. The direct replacement for txlist and tokentx.
• nr_getTokenHoldings — every BEP-20 token an address holds, with name, symbol, decimals and balance, paginated.
• nr_getTokenMeta and nr_getTokenHolders — token metadata and holder lists for a contract.
• nr_getNFTHoldings — NFTs owned by an address.
• nr_getContractCreationTransaction — who deployed a contract and in which transaction.
• nr_getTransactionByAddress and nr_getTokenBalance20 — address-scoped transactions and a single token balance.

Here is the call that replaces the old txlist for the last 20 BNB and BEP-20 transfers sent from a wallet:

curl -X POST https://bsc-mainnet.nodereal.io/v1/YOUR_API_KEY \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0", "id": 1,
    "method": "nr_getAssetTransfers",
    "params": [{
      "category": ["external", "20"],
      "fromAddress": "0xYourWallet",
      "fromBlock": "0x0", "toBlock": "latest",
      "order": "desc", "maxCount": "0x14"
    }]
  }'

Block numbers and counts are hex strings (0x14 = 20). Note that the docs cap a single query’s block range, so for long histories you page through results or split the range. And because block times on BSC are now around 0.45 seconds, “last 100,000 blocks” covers far less calendar time than it used to — roughly half a day.

BscScan vs BSCTrace: side-by-side comparison

Both explorers read the same BNB Smart Chain, so facts never differ — a successful transaction is successful on both. The differences are in context, tooling and price.

The pattern is clear. Choose BscScan when you need to know who is behind an address, when you want the approval checker, or when you are researching a token’s history. Choose BSCTrace when you want a faster, calmer interface, validator data, or an API you can use without paying. Many teams — ourselves included — keep both bookmarked, and add a third option from our BscScan alternatives list for days when either is under maintenance.

BSCTrace scores, pros and cons

The weighted total comes to 9.0. The API is the best value on BNB Smart Chain right now; data depth loses a little to BscScan’s labels; safety scores well — no aggressive ads, verification on board — but with fewer warnings on suspicious tokens you have to do more of the checking yourself.

Who BSCTrace suits best

Developers and small teams are the obvious winners. If you ran anything on the free BscScan API, BSCTrace plus MegaNode is the most direct replacement, and the JSON-RPC format means your existing Ethereum tooling just works. If you are building on testnet first, pair it with our BNB testnet explorer guide; if you want a self-hosted, open-source stack instead, read about Blockscout on BNB Smart Chain.

Stakers and validator watchers get one of the clearest validator views on BSC. Everyday users will find BSCTrace a pleasant, ad-light explorer and an excellent backup when BscScan is slow. For the quickest payment check with a shareable receipt, our own BNB transaction explorer is lighter still.

Verdict: 9.0 / 10. BSCTrace is the best BscScan alternative for developers in 2026: a fast, clean BNB Smart Chain explorer with contract verification and validator stats, backed by a free MegaNode API plan. It trails BscScan on community labels and depth of analytics.
