Solidity

OpenZeppelin is currently working on a base-64 library (OpenZeppelin/openzeppelin-contracts#2884) and it turns out that our optimizer is not yet good enough to get to the level of hand-optimized assembly in that case. We should add this code as a test case so that we can use it to evaluate our optimizer improvements.

In the PR and its comments you'll find versions of the

Issue

The default recommended configuration for mainnet is not provided in truffle-config, so it leads to misconfiguration.

I used the old style configuration parameter, gas/gasprice, which works fine for both the local

Description
Add a contract similar to Aave's AddressProvider or Uniswap's getPair() functionality.

Motivation
On-chain lookups of price oracles given the asset addresses.

Justification
String manipulation is difficult and expensive in Solidity, and you usually work with the token address, not its string name.

Currently the hardhat-vyper plugin is hardcoded to request the first 100 releases from the vyper github repo. This is fine for the time being as they aren't anywhere near 100 releases yet, but it should be refactored to handle a possibly paginated response from github.

Ideally it would aggregate all results from all pages returned from github before saving the list.json file.

Update this detector to filter based on the compiler version. Also, only output warning if one of the parameters is calldata.

If user already uses prettier we should use:

• user installed prettier version
• user defined config (.prettierrc / package.json config)

This way we ensure that typechain generated code matches style with the rest of the codebase.

Overview

Currently when I run brownie console, it recompiles all the contracts. Apparently due to some issue which is not identified.

I only want to compile once with brownie compile -all. That's it.
I work on the frontend side, I don't modify the contracts, I just need a local fork and run some scripts.

Currently it's slow as hell

Add an example to load file from a directory along with https://remix-ide.readthedocs.io/en/latest/locations.html#load-one-of-the-default-remix-files

Submit transactions as bundles using https://github.com/onbjerg/ethers-flashbots/ and a --flashbots flag.

Here's an example of how I used this in the past:

• https://github.com/gakonst/opensea-rs/blob/master/opensea-cli/src/contracts.rs#L131-L135
• https://github.com/gakonst/opensea-rs/blob/master/opensea-cli/src/contracts.rs#L299-L320

Alternatively we could use the Flashbots RPC: http
