Headless, GUI-less P2P seeder for the SmartNet network. Run it on any cheap VPS (no X / no webkit) to keep dApps alive 24/7 - it learns the app directory from the trackers, pulls each app's content-addressed blob over iroh-blobs and re-serves the identical blob, multiplying availability ("seeding").

It speaks the exact same wire protocol as the desktop client (iroh preset N0 + LAN mDNS, iroh_blobs::ALPN, tracker POST /announce + GET /apps). The signed {merkle, signature, publicKey} are read from each app's content.json inside the tar, so the seeder's relay re-announce verifies on the tracker unchanged.

cd seeder
cargo build --release        # binary: target/release/smartnet-seeder

Run it under systemd / tmux / nohup ... & to seed around the clock.

reward_address: ""                 # SmartHoldem S... address for future rewards
reward_passphrase: ""              # OR derive the address from this passphrase
poll_interval_secs: 30
relay_only: false                  # true = hide direct IP (relay only, no mDNS)
metrics_port: 9466                 # HTTP /metrics (JSON) + status page (0 = off)
metrics_interval_secs: 300         # also print a one-line STATS summary this often

The seeder serves a tiny dependency-free HTTP endpoint on metrics_port:

• GET /metrics → JSON: { uptimeSecs, appsSeeded, bytesSeeded, gbSeeded, storageLimitGb, endpointId, rewardAddress, trackers, lastAnnounceAcks }
• GET / → a small dark status page (uptime, apps, GB, acks, reward address).

It also prints a one-line STATS · uptime … · seeding N app(s) · X/Y GB · last acks … summary to the log every metrics_interval_secs. VPS operators can scrape /metrics (Prometheus-style polling) to see their contribution, and the rewardAddress ties that contribution to a payout identity for future seeding-reward ranking.

reward_address / reward_passphrase are reserved for the upcoming seeding-reward + proof-of-storage system. The passphrase derives the address with the same scheme as the SmartNet wallet, so you can import the same phrase into the wallet to control the rewards.

State (seeded.json) + the iroh blob store persist across restarts, so a restart re-announces immediately without re-downloading.
