Blockchain intelligence built for everyday crypto users.
The blockchain is the most transparent financial system ever built. Every swap, transfer, and contract call recorded is forever visible to anyone with an Internet connection. The catch: connecting it all into a coherent picture requires hours most people don't have. Raw hexadecimal, opcode arrays, wei denominations, and 42-character addresses. Block explorers show you everything. They explain nothing.
Forty-two random characters. Uniswap? Your exchange? A scam contract? The chain doesn't label it. You're left to guess — or ignore it entirely.
Amounts live in the chain's smallest unit. Converting wei to ETH, then ETH to its dollar value at the time it happened — that's three steps most people never take.
Function names describe the mechanics, not the meaning. What tokens moved? What changed in your balance? That part is left as an exercise for the reader.
Connect your wallets and get a real-time view of everything happening on-chain — from individual transactions to your full portfolio across every chain.

Deep forensics workspace for complex on-chain cases.
The chain only speaks in opcodes, hashes and wei. Hashtory keeps every fact exact, then rewrites it into a sentence you'd actually say out loud. Hashtory is your personal decoder, interpreting even the most complex transactions.

On June 6, 2026, this wallet sent 2.4 ETH into Uniswap's routing contract and received 6,012 USDC — the dollar-pegged stablecoin — back in return. The swap routed through the ETH/USDC 0.05% liquidity pool under the hood. All for $4.10 in network fees.

Advanced intelligence for when you need to understand exactly where funds came from, where they went, and why it matters.
Plain language never means softer facts. Every sentence traces directly back to what the chain recorded. Nothing added, nothing smoothed over.
Every number, address, and label in a Hashtory result maps directly to a specific log, opcode, or block field. We translate the chain to a language everyone understands. No inference, no filling in blanks, just the facts.
Hashtory never asks you to connect a wallet, sign a message, or approve anything. We query publicly available on-chain data only. Your keys stay exactly where they are.
Fiat values are pinned to the exact block timestamp, so you see what that ETH was worth when you sent it, not what it's worth today. On-chain history doesn't rewrite itself; neither do we.
Every Hashtory account includes the Reader. Unlock the full platform with Node or Validator.
Paste any transaction hash or wallet address. No account required.
This wallet address works on several different blockchains. Choose the network you think the activity happened on — if you're not sure, Ethereum is the most common.
