Smart Contracts

Basics

• Function types:

  • sc-function-types-I
  • External vs public
  • Overrides modifier

• Variables:

  • I
  • II

• Fallback functions:

  • Fallback
  • Fallback II

• Interfaces

• Libraries

• Testing:

  • Technical guide on how to write good unit tests in sc

Advanced

• DelegateCalls

• Upgradable SC:

  • Not all contracts are inmutable
  • Detailed explanation and Oz implementation
  • CardStack in-house solution

• Hooks

• Bytes I (official doc)

• Bytes II (old post)

• Bytes III (more complete)

• Abstract vs Interfaces

• Integration with Oz contracts

• Pausable Example Contract

Security

• Reentracy
• Reentrancy after Istanbul fork

Gas optimizations

• Gas tips
• Gas tips updated
• Storage is expensive
• Stack too deep and solution

EIPs
