Patterns & Best Practices
Patterns for Smart Contract Development
Dappsys: Safe, simple, and flexible Ethereum contract building blocks
has solutions for common problems in Ethereum/Solidity, eg.
should be consulted before creating own, untested, solutions
usage is described in Dapp-a-day 1-10 and Dapp-a-day 11-25
Likely the most widely-used libraries and smart contracts
Similar to Dappsys, more integrated into Truffle framework
Simpler Ethereum Multisig - especially section Benefits
CryptoFin Solidity Auditing Checklist - A checklist of common findings, and issues to watch out for when auditing a contract for a mainnet launch.
aragonOS: A smart contract framework for building DAOs, Dapps and protocols
Upgradeability: Smart contracts can be upgraded to a newer version
Permission control: By using the
authandauthPmodifiers, you can protect functionality so only other apps or entities can access itForwarders: aragonOS apps can send their intent to perform an action to other apps, so that intent is forwarded if a set of requirements are met
Organize contracts so they share the same contract storage and Ethereum address.
Solves the 24KB max contract size limit.
Upgrade diamonds by adding/replacing/removing any number of functions in a single transaction.
Upgrades are transparent by recording them with a standard event.
Get information about a diamond with events and/or four standard functions.
