nix-blockchain-development

A Nix flake offering blockchain development tools

Packages

This repo is provided as a Nix Flake. The packages defined here can be consumed via one of the flake output categories:

• overlays.default (which you can e.g. apply on top of Nixpkgs)
  • All packages are placed inside the metacraft-labs namespace
  • For example: metacraft-labs.solana
• packages.${arch}.${pkg} - suitable for use with nix shell

Usage examples

Imperative (ad hoc) with nix shell

# Replace solana with the package you want to use:
nix shell github:metacraft-labs/nix-blockchain-development#solana

Declarative with Nix Flakes dev shell

• flake.nix:

  {
    # <after>:
    # Opt into `nix-blockchain-development`'s substituter (binary cache).
    # `nixConfig` settings are not transitive so every user of a flake with a
    # custom binary cache must manually include its `nixConfig` settings for
    # substituters and trusted public keys:
    nixConfig = {
      extra-substituters = "https://nix-blockchain-development.cachix.org";
      extra-trusted-public-keys = "nix-blockchain-development.cachix.org-1:Ekei3RuW3Se+P/UIo6Q/oAgor/fVhFuuuX5jR8K/cdg=";
    };
  
    inputs = {
      # <before>:
      # nixpkgs.url = "github:NixOS/nixpkgs/nixos-22.05";
      # flake-utils.url = github:numtide/flake-utils;
  
      # <after>:
      # To ensure all packages from mcl-blockchain will be fetched from its
      # binary cache we need to ensure that we use exact same commit hash of the
      # inputs below. If we didn't, we may either:
      # * end up with multiple copies of the same package from nixpkgs
      # * be unable to use the binary cache, since the packages there where
      #   using different versions of their dependencies from nixpkgs
      mcl-blockchain.url = "github:metacraft-labs/nix-blockchain-development";
      nixpkgs.follows = "mcl-blockchain/nixpkgs";
      flake-utils.follows = "mcl-blockchain/flake-utils";
    };
  
    outputs = {
      self,
      nixpkgs,
      flake-utils,
      mcl-blockchain, # <after>
    }:
      flake-utils.lib.simpleFlake {
        inherit self nixpkgs;
        name = "solana-hello-world";
        shell = ./shell.nix;
        preOverlays = [mcl-blockchain.overlays.default]; # <after>
      };
  }

• shell.nix:

  {pkgs}:
  with pkgs;
    mkShell {
      packages = [
        metacraft-labs.polkadot # <after>
      ];
    }
