FOUNTAIN · Testnet Deployer

1 · Connect wallet

On a phone, open this page inside your wallet's browser (MetaMask, Trust Wallet, Binance Web3 Wallet, OKX…).

2 · Settings

For testing, you can leave Admin and Treasury as your own wallet. On mainnet, both must be Safe multisigs.

Admin (owner of settings): Safe on mainnet Treasury (receives mint proceeds + 5% royalty): fixed forever

WL start (your local time)

Upgrade timelock delay (seconds)

For testnet, start WL ~20 min from now so there's time to add test wallets. WL then runs 1 hour, and public runs 30 days after that. A 300 s timelock lets you test upgrades quickly (mainnet: 172800 = 48 h).

Public price (BNB)

Public limit per wallet (1–5)

Art base URI (TEST placeholder: real CID not locked yet) Hidden URI (shown before reveal) Collection URI

Chainlink VRF v2.5 wrapper (BSC Testnet): 0x471506e6ADED0b9811D05B8cAc8Db25eE839Ac94

3 · Deploy (3 transactions)

1

Timelock (controls upgrades)

2

FOUNTAIN implementation (the code)

3

FOUNTAIN proxy (the address you use), initialised with your settings

4 · Deployed

Save these addresses. They're also kept in this browser.

5 · Verify on BscScan (needed for Read/Write tabs)

BscScan's API verification needs a paid plan, but the website form is free. Do this once for each contract:

a

Download the file for the contract below.

b

On BscScan, open the contract's address → Contract tab → Verify and Publish.

c

Compiler type: Solidity (Standard-Json-Input) · Compiler: v0.8.24+commit.e11b9ed9 · License: MIT.

d

Upload the JSON file and paste the constructor arguments shown (if any), then submit.

e

Finally, on the proxy page: Contract → More Options → Is this a proxy? → Verify → Save. Then Read as Proxy / Write as Proxy appear.

6 · Test on BscScan

Use Write as Proxy with your wallet connected on BscScan:

1

addToWhitelist (admin, before WL start): e.g. ["0xYourTestWallet"]

2

At WL start: whitelistMint qty 1, value 0. A second try must fail.

3

After WL end: mint qty 1–5, payableAmount = 0.0003 × qty. A wrong amount must fail. A WL wallet that didn't claim must fail.

4

Admin: setPublicPrice, setPublicWalletLimit, pause/unpause, setBurnEnabled, then burn your token.

5

From a non-admin wallet, every admin function must fail. withdraw sends funds to the treasury.

6

Read: phase, mintInfo(wallet), totalMinted, isWhitelisted, missedWhitelist.

The reveal works only after the 30-day public window ends or after all 999 are minted. On testnet, that's best tested with a fresh deployment and a WL start a few minutes away.
