empty for now — the test track will show up once it is read from the chain
How long does a track live on devnet?
While accounts stay rent-exempt (ours do) — state does not expire on its own.
Devnet can still be wiped (ledger reset). There is no schedule: it may last months, or vanish at any time.
This is a sandbox. Persistence exists only on mainnet.
How upload works
The file is split into v1-sized 3.75 KB chunks — each becomes a PDA ["chunk", song_id, index]
You pay one tx from your wallet: rent + fees. Rent is a refundable Solana deposit (close is on the roadmap)
The server writes the chunks and publishes a manifest. The track appears on the board
