#  What it does:
#   1. Verifies node >= 18, git, npm.
#   2. Installs the public `solana-clawd` CLI globally from npm.
#   3. Writes a scaffolded ~/.openclawd/.env with sensible defaults.
#   4. Prints pair / mint / status next steps.
#
#  Self-contained: does NOT require access to the openclawd monorepo.
#  Full monorepo (if you have access):
#     gh repo clone x402agent/openclawd ~/.openclawd
