Best Practices

• Consensys best practices - This document provides a baseline knowledge of security considerations for intermediate Solidity programmers. It is maintained by ConsenSys Diligence, and the broader Ethereum community.
• Solidity Patterns - A compilation of patterns and best practices.

Libraries

• dapp-bin - Ethereum repo providing implementations for many common data structures and utilities in Solidity, Serpent and LLL.
• Solidity Collections - Collections of code snippets and utility libraries.
• OpenZeppelin - Framework to build secure smart contracts.

Examples

• Solidity By Example - Contract examples from the official docs.

Ethereum vs. Bitcoin

• Some key differences between Bitcoin and Ethereum - Features and differences between Bitcoin and Ethereum.

Substrate

Smart Contract Standards

The Ethereum Request for Comment repository

• ERCs - Ethereum Improvement Proposals

Tokens

• ERC-20 - Token contract for fungible assets.
• ERC-721 - Token standard for non-fungible assets.
• ERC-1155 - Multi Token Standard that aims to take the best from previous standards to create a fungibility-agnostic and gas-efficient token contract.
• ERC-918 - Mineable Token Standard.

Others

• ERC-165 - Creates a standard method to publish and detect what interfaces a smart contract implements.
• ERC-725 - A standard interface for a simple proxy account.
• ERC-173 - A standard interface for ownership of contracts.
