15 # viem/eip8168) and APIs are unchanged, so nothing else in your code moves.

17 # Usage:
18 # scripts/setup-viem-8130.sh [APP_DIR] [BUILD_DIR]
19 #
20 # APP_DIR project to install viem into (default: current directory)
21 # BUILD_DIR where to clone+build the fork (default: <APP_DIR>/.viem-8130-src;
22 # ~500 MB with node_modules — the script gitignores it in APP_DIR;
23 # share one BUILD_DIR outside the app when you have several apps)
24 #
25 # Env overrides:
26 # VIEM_FORK_REPO (default: https://github.com/chunter-cb/viem)
27 # VIEM_FORK_BRANCH (default: feat/eip-8130-production)
28 #
29 # Idempotent: re-running pulls the latest branch commit and rebuilds.
