Paste any Bitcoin or Ethereum address to see its current balance, USD value, most recent transactions, and thirty-day balance history. Known addresses from our whale registry — exchange cold wallets, institutional treasuries, dormant Satoshi-era addresses — are labeled automatically with editorial context.
The Address Explorer takes a single Bitcoin or Ethereum address and resolves it into a four-pane snapshot: current balance and USD value, the most recent fifty transactions, a thirty-day balance curve, and — when the address matches our curated registry — an editorial label explaining who controls it and why it matters. The goal is to give a curious reader more context than a generic block explorer, in fewer clicks, and with a clearer narrative frame.
Every address on Bitcoin and Ethereum is public by design. The chains do not have account names, profile pages, or contact directories — they have wallets identified by long strings of letters and numbers, and a transaction history anyone can read. Block explorers like Blockstream's and Etherscan have served this need for over a decade. What they generally do not do is connect the on-chain data back to the people, exchanges, ETFs, and protocols behind the addresses. That is the gap our tool aims to close.
The chain is inferred from the format of the address you paste. Bitcoin addresses come in three common varieties: legacy P2PKH addresses begin with 1, P2SH addresses begin with 3, and bech32 SegWit/Taproot addresses begin with bc1. Ethereum addresses always begin with 0x and contain exactly forty hexadecimal characters after the prefix. The detection runs as you type — when a valid format is recognized, the chain label appears beneath the input and the Explore button activates. No network call is made until you submit; everything up to that point is local pattern matching.
When an address you look up matches one in our whale registry, the detail page surfaces our editorial label — Binance cold wallet, Beacon Deposit Contract, MtGox-era dormant, and so on — together with a one-line rationale and a link to the registry entry. Attribution is curated by hand, drawn from public sources: SEC filings, exchange disclosures, on-chain research published by analytics firms, and government statements about seizures. We do not currently pull from paid services like Arkham, Chainalysis, or Nansen; expanding the attribution layer is on the v2 roadmap.
A few features are intentionally absent from this first version. Wallet clustering — the practice of identifying multiple addresses likely controlled by the same entity — requires heuristics that are easy to get wrong, and we would rather not show speculative clusters than mislabel a stranger's address. Token holdings beyond the native asset (ERC-20s for Ethereum, runes and ordinals for Bitcoin) require additional indexing infrastructure that we will add in a later iteration. NFT inventories, funds-flow graphs, and watchlists are also v2 and v3 territory. For now the tool answers four simple questions: what is the balance, where did it come from, where did it go, and is this address anyone we know.
Bitcoin data is served via Blockstream's public Esplora API — the same backend that powers blockstream.info — and reflects the canonical Bitcoin mainnet. Ethereum balances are read directly from a public RPC node, and transaction history is sourced from Etherscan's public API. Responses are cached at the CDN layer for a few minutes, so a refresh thirty seconds after a confirmed transaction may still show the previous state. For minute-by-minute tracking of unconfirmed transactions, consult the upstream explorers directly; the link to the canonical explorer view is provided on every detail page.
The launch version supports Bitcoin mainnet (all three address formats: legacy 1…, P2SH 3…, and bech32 bc1…) and Ethereum mainnet (any 0x address with 40 hex characters). EVM-compatible chains like Base, Arbitrum, Polygon, and BSC share the same address format as Ethereum but have separate on-chain state; those chains are on the post-launch roadmap. Solana, with its base58 address format and distinct RPC ecosystem, requires a separate integration and is also planned for a future iteration.
The address explorer is the address-level companion to our broader market and on-chain coverage. The Whale Wallets hub curates the largest known BTC and ETH addresses with editorial labels. The Sleeping Giants tracker surfaces wallets that have not moved in years. The Awakenings feed publishes when dormant whales come back to life. And the Whale Watch tracks unusually large transactions across the market in aggregate, rather than at the address level.
If you don't have an address handy, three well-known addresses to start with:
1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa) — the address that mined the first Bitcoin block on January 3, 2009. Holds about 104 BTC today, of which the original 50 BTC reward is permanently unspendable due to a quirk of the genesis block.0x00000000219ab540356cBB839Cbe05303d7705Fa) — the Ethereum smart contract that holds the majority of all staked ETH under the proof-of-stake protocol. The largest single Ethereum address by balance.1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF) — a Bitcoin address that has held a large balance untouched since 2011, one of the most-watched dormant wallets on the chain.The Address Explorer is a free tool that takes any Bitcoin or Ethereum address and resolves it into a snapshot view: the current balance and USD value, the most recent fifty transactions, a thirty-day balance chart, and — when the address matches our curated whale registry — an editorial label explaining who controls it and why it matters. Auto-detection of the chain happens from the address format as you type, so you do not need to specify whether the address is BTC or ETH.
The first version supports Bitcoin and Ethereum mainnet. These are the two largest chains by capitalization and the two with the deepest free public APIs. Additional chains are on the roadmap: EVM-compatible chains like Base, Arbitrum, Polygon, and BSC share Etherscan-style infrastructure and are a natural next step, and Solana support is also planned. Bitcoin Layer 2 chains like Lightning and Stacks would require a separate integration and are further out.
Address formats are distinct between Bitcoin and Ethereum, so detection runs as you type and does not need a network call. Bitcoin addresses come in three common formats: legacy P2PKH addresses begin with 1, P2SH addresses begin with 3, and bech32 SegWit/Taproot addresses begin with bc1. Ethereum addresses always begin with 0x followed by exactly forty hexadecimal characters. When a valid format is recognized, the chain label appears beneath the input and the Explore button activates.
Block explorers like Blockstream and Etherscan are the canonical source-of-truth views for on-chain data, and we link out to them on every detail page. Where our explorer adds value is in the editorial layer: addresses that match our curated whale registry get a label, a one-line rationale, and a link to the broader registry entry. We also unify Bitcoin and Ethereum lookups in a single interface, so you do not have to switch tools depending on which chain you are investigating. For deep blockchain forensics — looking at every input and output, examining script types, or following transaction graphs across many hops — the canonical explorers remain the right tool.
There is no per-user rate limit on the LiveCoinPrice side. Responses are served from the CDN with a short TTL, so most lookups complete in milliseconds and the same address looked up by many users only generates one upstream API call. The upstream services we depend on — Blockstream Esplora for Bitcoin and Etherscan plus a public RPC for Ethereum — have their own rate limits, which the proxy respects. In practice, casual use is unlimited; programmatic scraping at high volume may briefly slow down.
Every transaction on Bitcoin and Ethereum is public by design. The chains do not have account names, profile pages, or contact directories — they have wallets identified by long strings of letters and numbers and transaction histories that anyone with internet access can read. Our explorer surfaces only data that already exists on the public blockchain; we do not introduce any new attribution beyond what is publicly disclosed by entities themselves (SEC filings, exchange announcements, etc.) or what is widely accepted in published on-chain research. We do not store the addresses you look up, and lookups are not associated with any user identity.
Detail pages are rendered client-side from the URL and are not currently prerendered as static HTML, which means search engines that do not execute JavaScript will see only a thin shell. The trade-off is that prerendering every possible address would require maintaining a curated list of the most-trafficked addresses, which is a v2 project per our internal roadmap. The /explorer landing page is fully prerendered, so it can rank in search results and pass traffic into the detail pages. If a specific known address would be useful to prerender — an exchange cold wallet, a major ETF custody address, a famous dormant wallet — flagging it via the contact page is the right channel.
Possibly. The concept doc that shaped this build sketches a freemium model where heavy users move to a paid tier for unlimited lookups, wallet clustering, saved address watchlists, export to CSV, and API access. Nothing in the current build is gated. We will only add paid tiers if the free tool gets enough traction to make that investment make sense — and the free tool will remain free for casual use either way.
