Developer Guides
Tutorials, how-tos, and technical walkthroughs for building on Autheo and Web3.
Building Onchain AI Agents That Actually Work: Architecture, Wallets, and Failure Modes
Onchain AI agents are software systems that can hold assets, make decisions, and execute transactions autonomously on a blockchain. Building one that actually works in production requires a different mental model than building a chatbot or a traditional dapp.

ERC Standards You Should Know Beyond ERC-20 and ERC-721
ERC-20 and ERC-721 are table stakes. The standards that define how serious DeFi protocols, account abstraction systems, and real-world asset platforms are built in 2026 go much further. Here's what every dapp developer should understand , and when to reach for each one.

Building a Token Launch That Doesn't Get Rugged: A Developer's Guide
Token launches fail for two reasons: technical mistakes and trust failures. This guide addresses both. Whether you're launching a governance token, a utility token, or a protocol token, the principles here separate credible launches from ones that communities abandon , or worse, exploit.

Multi-Chain Deployments: Managing Smart Contracts Across 5+ Networks
The multi-chain world isn't coming , it's here. Most serious dapps today deploy across Ethereum mainnet, multiple L2s, and several EVM-compatible chains.

Liquidity Pool Mechanics Every Dapp Developer Should Understand
You don't need to build an AMM to need to understand how one works. If your protocol interacts with DEX liquidity, for swaps, for collateral pricing, for yield strategies, for token launches, then the mechanics of how liquidity pools work are your mechanics too. Here's the technical foundation.

How to Write Bulletproof Tests for Smart Contracts Using Foundry & Hardhat
A smart contract without thorough tests is a liability waiting to go live. This guide walks through unit testing, fuzz testing, invariant testing, and fork testing, with real examples in both Foundry and Hardhat. Ask most smart contract developers whether they test their code and they'll say yes.

Upgradeable Contracts Done Right: Proxy Patterns Explained
Upgradeability gives you flexibility, but done wrong, it's a security liability. This guide breaks down the three main proxy patterns in Solidity, when to use each, and the common mistakes that turn upgradeable contracts into vulnerabilities. Smart contracts are immutable by default.

Oracle Manipulation Attacks: What Dapp Developers Must Understand
Oracle manipulation is one of the most profitable attack vectors in DeFi. Protocols that rely on manipulable price data have been drained for hundreds of millions of dollars, not through exotic exploits, but through predictable failures in how price data was sourced and trusted.

From Zero to Deployed: Launching Your First Dapp with Autheo
Launching a dapp involves a lot more than writing a smart contract. This step-by-step guide walks you through the entire deployment lifecycle, from your local dev environment all the way to mainnet, using Autheo to keep everything organized. Most tutorials stop at "deploy your contract to a testnet.

The Smart Contract Audit Checklist Every Developer Needs Before Launch
Most smart contract exploits aren't sophisticated zero-days, they're preventable mistakes. This checklist walks you through the critical security checks every developer should complete before deploying to mainnet. In the past three years, over $3 billion has been lost to smart contract exploits.

Gas Optimization Secrets: Writing Leaner Solidity in 2026
Gas fees remain one of the biggest friction points in smart contract development. Whether you're deploying on Ethereum mainnet or an L2, writing lean Solidity isn't optional, it's a competitive advantage. Here's how to do it right.

PQC Migration UX Playbook for L1/L2s: Hybrid TLS, Signature Bloat, and a No-Panic Rollout Plan
A practical post-quantum rollout plan for L1/L2 teams: inventory your crypto surface, ship hybrid TLS key exchange, plan for signature-size bloat, and design a user-safe migration that avoids chain splits.

CI/CD for Web3: Automating Your Smart Contract Deployment Pipeline
Manual deployments don't scale, don't audit, and don't protect you at 2am when someone needs to push a fix. A well-designed CI/CD pipeline for smart contracts catches bugs automatically, enforces security gates, and makes deployments reproducible, every time, across every environment.

The Modern Dapp Developer's Stack in 2026
The Web3 developer tooling landscape has matured dramatically since the early days of Truffle and Web3.js. Today's production dapp teams work with a well-defined, opinionated stack , and the gap between teams using the right tools and teams using legacy choices is significant.

Understanding Reentrancy Attacks and How to Never Fall Victim
Reentrancy is one of the oldest and most destructive vulnerability classes in smart contract development. From the 2016 DAO hack to exploits happening today, the pattern keeps recurring , because developers keep underestimating it.

Why Your Dapp's UX Is Killing Adoption (And How to Fix It)
You can write perfect smart contracts and still build a dapp nobody uses. The gap between technically correct and actually usable is where most Web3 projects lose their users, often before those users even complete their first transaction.

Your DeFi App's Front Door Is Unlocked: A Practical Security Checklist for Users and Teams
Smart contract audits don't protect you when the website itself is compromised. Front-end and DNS attacks have become one of the most reliable ways attackers drain DeFi users, and the defenses are almost entirely different from on-chain security. This checklist covers both sides of the problem: what users can do right now, and what development teams must build into their infrastructure.

Post-Quantum Readiness Checklist for L1/L2 Builders: What You Can Automate Today
Post-quantum readiness means migrating your blockchain cryptographic stack to algorithms that resist both classical and quantum attacks. L1 and L2 builders need to act now, because adversaries are already harvesting encrypted data to decrypt later.

Smart Contract Security Best Practices for 2026
Smart contract security in 2026 demands multi-layered defenses, crypto theft reached $3.4 billion in 2025, access control failures caused $953.2 million in losses, and the OWASP 2026 Top 10 shows most losses trace to preventable patterns: CEI violations, missing access controls, and inadequate input validation.

Getting Started: Deploy Your First Smart Contract on Autheo
Deploying your first smart contract on Autheo uses standard EVM tooling, Solidity, Hardhat, and MetaMask, with the same workflow as Ethereum, while giving you immediate access to Autheo's integrated AI, compute, storage, and decentralized identity features from day one.
