Web3 technologies
Web3 technologies used in software projects, from smart contracts and wallets to blockchain indexing and data access.
Protocols, wallets, contracts, and indexing from shipped systems—grouped here with project evidence. Web3 engineering goes deeper on the work.
Writing about Web3
Tokenized Securities at the NYSE
The NYSE is developing a tokenized-securities platform for 24/7 trading and onchain settlement, subject to regulatory approval.
Why I'm Bullish on 2026
Why I expect AI agents, stablecoins, wallet signing, and tokenized markets to converge in products over the coming year.
Intersection of AI and Web3 (Part 2)
How agentic finance, stablecoin payment rails, and decentralized AI infrastructure are starting to connect in real products.
Intent-Based Multichain DeFi
How solver networks and ERC-7683 support intent-based transactions across EVM chains, Solana, and Cosmos.
Stablecoin Summer
Why the GENIUS Act and Treasury-backed reserves matter as stablecoins become infrastructure for payments and settlement.
Agentic Finance
How AP2, x402, and agentic commerce protocols could let AI agents authorize payments and settle transactions with stablecoins.
Web3 Composability
How shared token, liquidity, governance, and DeFi standards accelerate new products while introducing systemic risk.
EVM Token Standards Overview
What ERC-20, ERC-1155, ERC-6909, and ERC-7281 each define, where each one fits, and how they compare on batching, approvals, and gas.
Managing Risks in DeFi
The technical, economic, systemic, and operational risks in DeFi, the incidents that exposed each one, and the checks and tools I use before trusting a protocol.
AMMs, Liquidity Pools & Yield Farming
How automated market makers price trades from liquidity pools, what liquidity providers earn and risk, and yield farming strategies on Ethereum, Solana, Cosmos, and zkSync.
Trading Engines - Order Books & AMMs
How order books and AMMs match trades, which projects run each model and hybrids of both, and when I would pick one over the other.
The Skillset of a Product Engineer
Why product engineers take ownership of user needs, interfaces, and systems instead of working within one technical layer.
How USDT0 Improves Stablecoin Bridging
How USDT0 and LayerZero's OFT standard move USDT across chains without wrapping, with unified liquidity and a smaller bridge attack surface.
EVM on Bitcoin - The Future of DeFi
The Layer 2s, sidechains, and token standards bringing programmability to Bitcoin, and what EVM compatibility through projects like SovaEVM adds for Solidity developers.
The Power of Bitcoin Runes
How Runes represents fungible tokens through Bitcoin's UTXO model, and what its design does and does not provide.
Engineering Principles
The principles I use to balance software quality, reliability, and delivery speed across products and technical stacks.
Math in JavaScript and DeFi
Floating-point quirks, precision, and BigInt choices I use when JavaScript math has to hold up in DeFi contracts and onchain apps.
Modern Next.js Web3 Architecture
How I structure Next.js Web3 applications using URL state, colocated features, TanStack Query, wagmi, and viem.
Introducing BasilicEVM
A look at my EVM starter for wallet connections, contract types, and chain interactions using Foundry, viem, and wagmi.
Comparing Ethers.js and Viem/Wagmi
How Ethers.js and Viem with Wagmi differ on bundle size, modularity, types, and React integration, and where each one runs at Bitlauncher.
The Intersection of AI and Web3
A July 2024 snapshot of shared infrastructure between AI and Web3: compute, identity, data, and open networks.
