I Sniped a Solana Token in 400ms — Here's the Full Tech Stack Sniping a newly launched token on Solana is a high-stakes game that requires precision, speed, and a deep understanding of the ecosystem. Recently, I successfully sniped a Solana token in just 400ms — and I want to share the exact tech stack and strategies I used to make it happen. This article will dive deep into Jito MEV bundles, Jup…

- Bullish has entered into a definitive agreement to acquire Equiniti, a leading global transfer agent serving nearly 3,000 issuer clients, 15,000 total corporate clients, 20 million shareholders, and processing $500 billion in annual payments. - The combination creates the first fully integrated blockchain-enabled, blue-chip issuer services provider — unifying a regulated transfer agent with end…

Katie Haun announced on Monday that $1 billion has been raised across new funds to continue the firm’s thesis of backing crypto and blockchain startups.

LLMs guess. The EVM executes. This is the fundamental friction at the heart of Web3 AI. Large Language Models are, by design, probabilistic hallucination engines—they are built to be creative. The Ethereum Virtual Machine, on the other hand, is a cold, ruthless, and deterministic state machine. It does exactly what it is told, down to the byte, without remorse. When you bridge a probabilistic bra…

DTCC will facilitate limited production trades of securities tokenized via DTC's tokenization service.

Published Apr 27, 2026 How Monero’s proof of work works Monero’s proof of work is called RandomX. Monero does not ask miners to run the same tiny hash function over and over. It asks them to run a small random program on a virtual machine, hit memory hard while doing it, and then hash the result. Bitcoin’s proof of work is great for specialized chips because the work never changes. RandomX was bu…

Federated learning (FL) is a decentralized machine learning (ML) approach that can be used for intrusion detection in Internet of Things (IoT) devices. It involves the local training of AI models and their aggregation at a central server. This methodology eliminates the need for data sharing between IoT devices while fostering collaborative model improvement. Nonetheless, concerns arise from the …

What I Did I used a simple JavaScript script and the @solana/kit library to programmatically generate a new keypair, saved the secret key to a local .json file, and then wrote a second script to extract that seed so I could manually import it into my Phantom wallet extension for devnet testing. What Surprised Me The biggest shift from Web2 was realizing that my "identity" is just a cryptographic …

Best Crypto Trading Bot API in 2026: Binance, CoinGecko, CoinGlass, and Regime Compared Building a crypto trading bot in 2026 means choosing from dozens of APIs. Some give you raw market data. Some give you derivatives analytics. Very few tell you whether you should actually be trading right now. This guide compares the four APIs that matter most for bot builders: Binance, CoinGecko, CoinGlass, a…

Most Web3 tutorials give you a token contract and stop there. I went furtherand built the full stack: a Solidity ERC-20 token, a Hardhat test suite, and a React dApp with MetaMask integration and transaction history. Here is every technical decision I made. GitHub: https://github.com/Carter254g/harambee-dapp What I Built HarambeeCoin (HBC) is a custom ERC-20 token. The dApp lets you connect MetaM…

Nowadays blockchains treat privacy like it's just an extra. Just an additional feature. Everything is visible and public. This architecture works for systems where public transparency is the end goal. But what happens when you begin to handle big data, medical records or sensitive information? It collapses. Full transparency and accountability is not a feature in these contexts, it's a problem. T…

Day 13 of 100 Days of Solana — Reflecting on Reading On-Chain Data When I started this challenge two weeks ago with Major League Hacking(MLH), I thought blockchain was just a ledger with transactions. I was wrong—and that realization is worth writing about. The Expectation vs. Reality Before I touched any code, I imagined blockchain data like this: Transactions sit in a database somewhere I'd ne…

Diving into blockchain data (Solana specifically) changed how I think about “data” entirely 👇 At first, I expected something like a clean database—tables, rows, easy queries. Reality? It’s raw account state + transactions. Public, yes… but you have to decode and interpret everything yourself. ⚡ The “click” moment: You don’t query data—you reconstruct it. State isn’t handed to you; it’s derived fr…

I have deployed a collection of independent smart contract protocols on Ethereum mainnet. Each one is finished infrastructure: Immutable, ownerless, no upgrade path. This post is a technical introduction to what they are, how they are structured, and how to build on them. The pattern Every protocol follows the same two-component structure: An ERC primitive that represents a physical or digital as…

Why Most Crypto Bots Get Sandwiched (And How to Prevent It) If you've ever run a crypto trading bot on Ethereum or Solana, you've likely experienced the frustration of getting "sandwiched" - watching your profitable trade turn into a loss because MEV (Maximal Extractable Value) bots frontran and backran your transaction. Today I'll explain exactly how sandwich attacks work, why most naive bots ar…

I recently joined the 100 Days of Solana challenge, and in the first few days I did some pretty basic things: Generated a wallet Funded it using devnet Connected it to apps Sent transactions Sounds simple, right? But it raised a bigger question for me: If there’s no email/password… how does identity even work here? If you're coming from Web2, this part can feel confusing at first. Let me break it…

Anonymous Membership Proofs on Midnight: Building Privacy-Preserving Allowlists Last month, I was tasked with building an allowlist system for a Midnight dApp. The requirement seemed simple: let authorized users access a feature without revealing who they are. In the clear-text world, you'd just check if (user in allowedList) . But on a privacy platform, that if statement leaks everything. This t…

Compact vs Solidity: Limitations and Advantages The emergence of privacy focused blockchain systems has introduced a new way of writing smart contracts. Compact is one such language designed for Midnight, a network that prioritizes confidential computation using zero knowledge proofs. Developers who are familiar with Solidity will notice that Compact is not just a new syntax but a fundamentally d…

A few months ago I started building a small tool on Solana. Nothing crazy. Just something that lets you: create a token attach metadata add liquidity and actually use it That was the idea. Keep it simple. The Plan Was Pretty Straightforward I didn’t want to build another “platform”. No custody. No custom smart contracts I fully control. Just an interface that prepares transactions and lets users …
