Dapp tools by DappHub

Hello!

This repository contains the source code for several Ethereum tools hand-crafted and maintained by DappHub, along with dependency management, courtesy of Nix.

Contents:

• Dapp - all you need Ethereum development tool. Build, test, debug & deploy solidity contracts.
• Seth - Ethereum CLI. Query contracts, send transactions, follow logs, slice & dice data.
• Hevm - Ethereum evaluator. Fully complient Haskell EVM implementation.
• Ethsign - sign Ethereum transactions from a local keystore.

Installation

Install Nix if you haven't already:

# user must be in sudoers
curl -L https://nixos.org/nix/install | sh

# Run this or login again to use Nix
. "$HOME/.nix-profile/etc/profile.d/nix.sh"

Then install dapptools:

curl https://dapp.tools/install | sh

Installing custom solc versions

You can specify a custom solc version to run within dapp with dapp --use solc:x.y.z test, but you can also install any supported solc "standalone" (i.e. add it to your $PATH) with:

nix-env -iA solc-versions.solc_x_y_z \
  -if https://github.com/dapphub/dapptools/tarball/master

(NOTE: if you haven't installed dapptools with the one-line installer, you'll have to manually pass substituters in the command above, or configure Cachix manually, to avoid compilation)

For a list of the supported solc versions, check ./nix/solc-versions.nix.

Versions of solc that haven't yet landed in nixpkgs can be found under the unreleased key: solc-versions.unreleased.solc_x_y_z.

(NOTE: not all versions are supported on macOS platforms.)
