EOS block explorer and account lookup

6 min read

Search an EOS account or transaction

The tool below queries public API nodes run by EOS block producers and infrastructure teams (Greymass, EOS USA, EOS Rio and EOS Nation). If one node is slow, it falls back to the next. Nothing is stored on our side; your browser sends the request directly to the node.

Not sure what to try? Search eosio.token (the legacy token contract) or core.vaulta (the A token and swap contract) to see how system accounts look.

What is an EOS block explorer?

A block explorer is a search engine for a blockchain. Every transfer, stake, vote and smart contract call on EOS is recorded publicly, and an explorer turns that raw data into something readable. You use one to answer simple questions: did my withdrawal arrive, how much RAM do I own, which producers did I vote for, is this contract real?

EOS explorers look a bit different from Ethereum’s Etherscan. Instead of long hexadecimal addresses, EOS uses human-readable account names such as swap.alcor or tethertether. Accounts also carry resources (RAM, CPU, NET) and permissions, so an account page shows much more than a balance.

How to read an account page

When you search an account, the explorer shows several fields. Here’s what each one means in plain English.

A vs legacy EOS: the two-balance quirk

Since the Vaulta rebrand, two tokens live side by side on the same chain. A is issued by the core.vaulta contract; old EOS sits in eosio.token. Swapping is 1:1 with no deadline, so plenty of accounts still hold some EOS. That’s why our tool shows both lines.

One gotcha: the node’s standard get_account response reports core_liquid_balance in EOS only. Older wallets and explorers that rely on that field will show an EOS balance and quietly ignore A. If your balance “disappeared” after you swapped, it’s almost certainly sitting in A. Our EOS to A swap guide explains the conversion.

RAM, CPU and NET at a glance

RAM is storage you own; each token you hold and each row a contract stores for you takes a few bytes. CPU and NET are rented for 24 hours through PowerUp. If CPU shows 100% used, your next transaction may fail until the window resets or you rent more. Our EOS resources guide has a calculator to estimate how much you need.

How to check an EOS transaction

1. Find the transaction ID

   Your wallet or exchange shows it after sending, often labelled “TxID” or “hash”. It is a 64-character string of 0–9 and a–f.

2. Paste it into the explorer

   Use the search box above. The tool asks public history nodes and falls back to another node if one is slow.

3. Check block, time and status

   “Irreversible” means final. Under the Savanna consensus, the gap between the newest block and the last final block is usually just two blocks, about one second.

4. Read the actions

   A plain transfer shows transfer on core.vaulta (for A) or eosio.token (for EOS), with sender, receiver, amount and memo.

5. Compare with what you expected

   Wrong memo on an exchange deposit? Wrong token contract? This is where you catch it. Contact the exchange with the TxID if funds don’t appear.

Which EOS explorers still work?

The explorer landscape changed a lot after 2024. Several bookmarks that served EOS for years now lead somewhere else.

• Unicove (unicove.com): the official Vaulta portal by Greymass. It doubles as a web wallet interface for swaps, staking and RAM. Account pages follow the pattern unicove.com/en/vaulta/account/name.
• EOS Authority (eosauthority.com): long-running explorer with detailed REX statistics. Add ?network=eos to account URLs.
• eosflare (eosflare.io): still responds, but we could not confirm how fresh its data is.
• Hyperion: not a consumer explorer but the history API most tools use under the hood, with a Swagger interface for developers.
• exSat explorer (scan.exsat.network): for exSat and XSAT data, not for regular A transfers.

Avoid: bloks.io, which now redirects to the XPR Network explorer; EOSQ, which EOS Nation has discontinued; and the old EOS EVM explorer, whose domain no longer resolves after the October 2025 shutdown.

EOS account names explained

Account names are one of the friendliest parts of EOS. Instead of a 42-character address, your account might be coffeelover1. The rules are strict, though:

• Lowercase letters a–z, digits 1–5 and the dot only. No 0, 6, 7, 8 or 9.
• Standard names are exactly 12 characters. Shorter names are premium names won in an on-chain auction.
• A name cannot start with a digit or a dot, or end with a dot.
• Suffix names like name.bar can only be created by whoever owns bar.

Creating an account means another account pays for about 3 KB of RAM on your behalf, which is why free account services exist. Details are in our guide to creating an EOS account, and terms like “permission” and “multisig” are defined in the EOS glossary.

For developers: query the chain yourself

Everything the tool does, you can do with a simple HTTP call to a public node. These endpoints allow browser requests (CORS) and need no API key.

• A balance: POST /v1/chain/get_currency_balance with code core.vaulta, your account and symbol A.
• Legacy EOS balance: the same call with code eosio.token and symbol EOS.
• Resources and permissions: POST /v1/chain/get_account with the account name.
• Transaction lookup: GET /v2/history/get_transaction?id= on a Hyperion node such as eos.hyperion.eosrio.io.

Good chain API nodes to start with are eos.greymass.com, eos.eosusa.io, api.eosrio.io and eos.api.eosnation.io. Note that EOS Nation’s node no longer serves history (it returns 410 Gone), and some older endpoints such as api.eosn.io have stopped resolving.

Privacy: what an explorer reveals

Blockchains are public. Anyone who knows your account name can see your balances, transaction history, staking and producer votes. Account names are pseudonymous, but if you ever link a name to your identity, for example by posting it on social media or receiving a payment from someone who knows you, that history becomes yours in public. Consider using separate accounts for public and private activity, and read our EOS safety guide for more practical tips.
