H2O — Water (Battle Currency)
One-line pitch: H2O is the water you earn from winning battles in WAR. It’s the game’s main “loot” currency.
What this is
Section titled “What this is”H2O is an ERC-20 token with the symbol 水 (Chinese for “water”). You earn it by beating high-scores at positions in WAR. It’s not bought, not staked — it drops as a battle reward.
The supply is managed by WAR: when you win, WAR calls Mint(YourAddress, Amount) and your wallet balance goes up.
There’s also an overflow protection rule: you can’t hoard unlimited H2O. If your balance gets too large, excess is diverted to WORLD (funding territory rewards) or burned.
If you’ve played a web3 game before
Section titled “If you’ve played a web3 game before”- Closest analogy: loot tokens from a P2E game — earned through gameplay, not bought.
- Or: experience points with a hard cap — past a certain amount, the overflow spills somewhere useful.
- Or: MOBA gold — generated by winning engagements, spent on upgrades.
| Dysnomia term | What it maps to |
|---|---|
| H2O (水) | Battle-reward ERC-20 |

WAR calls this when you win; you can’t call it yourself |
| Balance | Your wallet’s H2O count |
| Overflow | Auto-spill mechanism — too-large balance leaks to WORLD or burns |
What you actually do with it
Section titled “What you actually do with it”- Fight battles in WAR to earn it.
- Hold it as your visible “wins trophy.” It’s the proof-of-competitive-activity currency.
- Transfer / trade like any ERC-20 — it’s standard.
- Don’t try to Mint — only WAR can. Calling
Mintfrom your wallet will revert.
Use these calls here. Simulations preview the current state; each confirmed call is a separate transaction.

Rewards / costs
Section titled “Rewards / costs”- Cost: none (aside from the cost of earning it via WAR).
- Reward: H2O is itself the reward.
Requirements & gating
Section titled “Requirements & gating”- To earn: win at WAR. No other path.
- To transfer / receive: nothing special, it’s a standard ERC-20.
Where it connects
Section titled “Where it connects”Minted by WAR. Spills over into WORLD when balances get too fat. Referenced in CHEON reward calculations and in YUE bank accounting.
Quick FAQ
Section titled “Quick FAQ”Q: Can I buy H2O on an exchange? A: Potentially, if someone lists it, but the canonical source is winning battles. It’s designed as an earned currency.
Q: What triggers the overflow? A: A threshold on your balance. When WAR tries to mint to an already-large holder, the extra is routed elsewhere.
Q: Is H2O deflationary? A: Partially — overflow can burn it. But WAR wins mint new H2O, so net supply drifts with gameplay volume.
Q: Can I lose H2O I already earned? A: Not passively. You can transfer it away, but WAR can’t take it back. (Overflow only affects new mints, not existing balance.)
