Lightweight Sourcify repository hosting

Sourcify publishes a compressed RepositoryV2 weekly, with contracts from all chains. You can follow its instructions to download the entire repository yourself and self-host it:

curl -L -O https://repo-backup.sourcify.dev/manifest.json
jq -r '.files[].path' manifest.json | xargs -I {} curl -L -O https://repo-backup.sourcify.dev/{}
cat sourcify-repository-*.part.gz.* | tar -xz

Hosting the repository locally

You can host the extracted repository using Caddy, a lightweight, portable HTTP(S) server:

1. Install Caddy. You can find installation instructions on the official Caddy website.

2. Run a Caddy file server on localhost:7877:

   caddy file-server --root ./repositoryV2/ --listen 127.0.0.1:7877
   

   Alternatively, use a Caddyfile instead

   1. Create a Caddyfile. In the same directory used to run the download commands, create a file named Caddyfile with the following content:

      # Caddyfile for hosting Sourcify RepositoryV2
      localhost:7877 {
          # Set the root directory to the extracted repository folder
          root * ./repositoryV2
      
          # Serve files from the repository
          file_server
      }
      

   2. In the directory containing the Caddyfile, run

      caddy run
      

3. Update the Otterscan config. Your Sourcify repository is now hosted at http://localhost:7877. Update your Otterscan config to point to your new repository URL:

   "sourcify": {
     "sources": {
       "ipfs": "http://localhost:7877",
       "central_server": "http://localhost:7877"
     },
     "backendFormat": "RepositoryV2"
   }
   

   Replace http://localhost:7877 with your server's domain or IP address if you're accessing it remotely. If you want to host your repo over HTTPS, follow Caddy's instructions at https://caddyserver.com/docs/automatic-https.
