Proven playbooks for shipping
Opinionated, code-first tutorials. Ship features the way experienced Ethereum teams actually ship them.
How to Create an ERC-3643 Permissioned Token for RWA
Deploy a T-REX / ERC-3643 security token suite with Identity Registry and Modular Compliance — then register OnchainID investors and mint as a token agent.
How to Launch an ERC20 Token in 3 Minutes
Create and deploy a production-ready ERC20 token with OpenZeppelin Burnable, Permit, and Votes using Token Creator — then verify on Etherscan in one click.
How to Deploy an NFT Collection with IPFS Metadata
Pin artwork and JSON metadata to permanent storage, deploy an OpenZeppelin ERC721 with URIStorage, and enforce creator royalties with ERC2981 — step by step.
Governor DAO 101 — Deploy OpenZeppelin Governance
Learn how to wire ERC20Votes, TimelockController, and OpenZeppelin Governor into a production DAO — deployment order, roles, and the full proposal lifecycle.
How to Build a Staking Contract on Ethereum
Deploy a Synthetix-style staking contract, fund reward emissions, and avoid reward-rate pitfalls that silently underpay stakers — with OpenZeppelin-safe patterns.
Reentrancy Checklist for Solidity Smart Contracts
Seven reentrancy patterns every Solidity developer should internalize before mainnet — CEI, ReentrancyGuard, pull payments, Pausable, and cross-function traps.
How to Verify Smart Contracts on Etherscan
Verify OpenZeppelin contracts on Etherscan after deploy — and fix failures when constructor args, compiler settings, or libraries do not match the on-chain bytecode.
