On July 8, 2025, two Ethereum wallets funded during the network’s Genesis block in 2015 moved a combined 1,140 ETH, worth nearly $2.9 million. These addresses, starting with “0x27” and “0x7f,” had remained inactive since July 30, 2015 - the day Ethereum launched its mainnet during the "Frontier" phase.
Labeled as GENESIS-funded on Etherscan, the wallets received their Ether directly at launch. At the time, ETH traded for under $1. Today, it sits above $2,500, marking a nearly 90,000% appreciation.
But more than just price history, this event raises critical questions:
The answer: comprehensive blockchain address history- from Genesis block to present day.
Dormant wallet activations are becoming more common. In 2024, multiple Satoshi-era Bitcoin wallets - inactive for 14+ years - moved over $44 million in BTC.
These high-value, long-silent transfers:
In crypto, what’s old is often gold - and understanding the past is key to interpreting the present.
To truly understand what happened with these Ethereum Genesis wallets, you need more than surface-level data. You need to follow their:
This level of visibility is only possible with access to full blockchain address history, something most public explorers or node interfaces can’t provide efficiently - especially across multiple blockchains.
Crypto APIs’ Address History service solves this exact challenge.
It gives developers, analysts, and businesses the ability to retrieve data about every transaction tied to any wallet, dating back to the Genesis block - on multiple chains including Ethereum, Bitcoin, Polygon, and more.
In the Ethereum Genesis wallet case, this tool reveals:
Track whale wallets, detect suspicious activity, and build risk monitoring systems.
Meet regulatory needs with verifiable proof of funds from the very first transaction.
Analyze holding patterns, wallet dormancy, and behavioral trends.
Build smarter dApps and dashboards with data that spans the entire blockchain history.
With Crypto APIs, you can bring context, transparency, and precision to your blockchain tools and investigations.
Crypto APIs offers a single interface for multiple networks, including:
No need for archive nodes or custom indexing - Crypto APIs does the heavy lifting.
The reactivation of two Ethereum Genesis wallets and their $2.9M ETH transfer isn’t just a curiosity - it's a reminder. Blockchain doesn’t forget, but most tools only let you see part of the story.
To uncover the entire story, you need:
Whether you're building apps, auditing transactions, or investigating unusual activity, Crypto APIs’ Address History service gives you the full picture - from Genesis to now. Combine it with our Address Latest service to obtain both historical and real time blockchain data.
