03 / How It Works
Trading can support
clean water.
$WATER uses Pump.fun's built-in Charity Coins option, powered by donate.gg. Watercoin never holds the donated funds.
01TRADE
Every buy and sell of $WATER on Pump.fun's bonding curve and, after graduation, on PumpSwap carries a creator fee. The rate is fixed on the bonding curve; on PumpSwap it changes with the coin's market cap.
02COLLECT
Creator fees accrue in Pump.fun's creator vault and are split according to the coin's on-chain fee-sharing configuration.
03DONATE
The donate.gg share goes to a Pump.fun donation escrow and is relayed in SOL to donate.gg, which converts it and pays the selected charity in US dollars.
04VERIFY
Every step up to donate.gg is public on Solana. The Water Meter reads it directly, and adds what donate.gg reports and any receipts the charity publishes.
ⓘWhat reaches the charity is less than the creator fees. donate.gg converts SOL to USD and charges a service fee. Its FAQ lists 10% for donations made through apps that use its API, which is how Pump.fun connects to it. Pump.fun doesn't vet the charities listed on donate.gg, so the Water Meter shows exactly which organization the on-chain config points to.
