In today’s rapidly evolving blockchain, Web3, and crypto ecosystems, smart contracts audit services form the backbone of decentralized applications and DeFi protocols. But while these autonomous programs unlock a new paradigm of trustless interactions, they also introduce significant security vulnerabilities. A…
Working with EVM blockchains eventually brings every developer to the same moment: the contract should behave one way, but the chain insists otherwise. The transaction fails silently, gas burns, the api returns a generic message, and suddenly you’re staring at…
Polkadot has entered a new era. With the recent migration to the Polkadot Asset Hub, the network has redefined how assets are created, managed, and transferred across its ecosystem.This move isn’t just a technical adjustment — it’s a fundamental shift…
When working with EVM blockchains, developers often need deep insights into what actually happens under the hood of a smart contract execution. High-level transaction receipts are rarely enough—especially when debugging complex interactions, analyzing gas consumption, or reverse-engineering contract logic. This…
If you’ve ever tried to understand why a transaction behaved differently than expected, or you needed to dig deeper than what logs and receipts tell you, then you’ve probably bumped into one important truth: on EVM blockchains, the “real action”…
In modern EVM development, engineers need more than a standard RPC endpoint. When a trace is required to analyze execution, or when a developer needs to inspect internal state transitions, a simple request is not enough. This is why NOWNodes…
Where to hold you crypto? One of the best option is to use Cold crypto wallets. In 2025, it is really important because of the rise of sophisticated hacking techniques and scams has underscored the need for reliable storage solutions.…
If you’ve ever tried to explore the full history of the Ethereum blockchain, you know how massive it is — and how hard it can be to host an Ethereum archive node yourself. Good news: you don’t have to anymore.…
October has been a busy and exciting month for the NOWNodes team. We’ve focused on refining the user experience, expanding blockchain coverage, and giving our community more control over how they manage and scale their infrastructure. This product update introduces…
The Core blockchain is one of the fastest-growing EVM-compatible networks, designed to combine Bitcoin’s security with Ethereum’s smart contract capabilities.If you’re a developer or a crypto enthusiast, you’ll eventually need to connect to the Core RPC — the Remote Procedure…
