Get pbcopy and pbpaste in Arch Linux

Get pbcopy and pbpaste in Arch Linux

First you need the 'xsel' package.

$> pacman -S xsel

Then create aliases.

alias pbcopy='xsel --clipboard --input'

alias pbpaste='xsel --clipboard --output'

Sending Ether Cheat Sheet

Sending Ether Cheat Sheet

TLDR

🥇 Instead of sending Ether, use the withdrawal pattern

🥈 If you really need to send Ether, use a safe wrapper like OpenZeppelin's Address.sendValue(addr, amount)

🥉 If you really need to send Ether without dependencies, use (bool success, ) = addr.call{value: amount}("")

A single-file simplest possible template for a contract that obtains a flash loan from dydx, does things, and pays it back.

// The ABI encoder is necessary, but older Solidity versions should work
pragma solidity ^0.7.0;
pragma experimental ABIEncoderV2;
// These definitions are taken from across multiple dydx contracts, and are
// limited to just the bare minimum necessary to make flash loans work.

Async Solidity Contracts

Having seen @pirapira's sketch of Bamboo ( https://github.com/pirapira/bamboo/ ), which proposed to add better control about the "smart contract program flow", even across calls, I thought that this should certainly be added to Solidity, and actually, it might even be possible now to a certain degree using inline assembly.

The problem is that with many functions in a contract, it is not always clear which can be called at which stage in the contract's lifetime. Certain smart contracts would be easier to understand if written as follows:
