Solidity

A “rebase token” (sometimes “rebasing token”) is an ERC-20 token where the total supply, and the balances of token holders, can change without transfers…

Q numbers store fractions as binary fixed-point integers in Qm.n format. Learn to convert to and from Q numbers, their max value, and how to do math on them.

Dynamic-sized types in Solidity (sometimes referred to as complex types) are data types with variable size.

Reverting transactions using inline assembly can be more gas-efficient than using the high-level Solidity revert or require statement.

Our intent is not to be patronizing towards developers early in their journey with this article.

In the previous tutorials, the seeds=[] parameter was always empty. If we put data into it, it behaves like a key or keys in a Solidity mapping.

A Solana transaction must specify in advance the accounts it will modify or read as part of a transaction.

In our Solana tutorials thus far, we've only had one account initialize and write to the account. In practice, this is very restrictive.

Today we will cover the analogs of all the block variables from Solidity. Not all of them have 1-1 analogs.

This article describes all the kinds of errors that can happen when a smart contract is called, and how the Solidity Try / Catch block responds (or fails…

This article examines the storage architecture of the Ethereum Smart Contracts.

All of these questions can be answered in three sentences or less. What changed with block.timestamp before and after proof of stake?
