AQUA is the utility token of the AquaCoin ERP — the water utilities workspace where testing, treatment, distribution and stewardship are run on one record: what the samples read, what the plant did, where the water went, and what it cost, kept per system from source to tap.
Holding AQUA is the key. Nothing is spent or transferred to use the ERP: entry asks your wallet to hold at least 1 AQUA, and each module you activate asks for one more AQUA held while it stays active — hold 4 AQUA with three modules active, for example. If the hold drops, the modules pause until it is restored; reconnect and they resume on their own.
Earning inside the ERP is simple and stated up front: every file you add to your vault earns a 1 AQUA credit on your ledger, duplicates earn nothing, and every view or download of a vault file — your own files included — costs credits at 0.1 AQUA per megabyte. Files are hashed with SHA-256 when they land and are queued for anchoring on Avalanche; until that anchor runs the ERP says so plainly: queued, not anchored. Vault files can only be viewed inside the workspace that uploaded them.
There is no Buy Direct listing for AQUA on XMarkets yet — that shelf today lists CJV, OMC and XMA — but AQUA moves between holders on the XMarkets marketplace, and swaps on XMarkets cover all 39 Omnichain tokens, AQUA included. New AQUA is mined on Omnichain.
Questions about a hold, a credit, or a module are answered from your own ledger and gate state on the Dashboard page — what you see there is what the ERP itself checks.
