When you use apps on the internet, there are tiny behind-the-scenes costs โ like stamps needed to send a letter. On our platform, we pay all of those background costs(rent fees, gas fees, and PDA fees). You don't have to worry about them at all.
Think of it like an amusement park
You can only use this smart contract through our platform. You can't jump the fence and ride the rides โ you have to buy a ticket at the front gate. This ensures a safe and controlled experience for everyone.
Imagine a rocket launch pad. Before a rocket (song) flies into space (the main platform), it sits on the launchpad for a while so people can decide if they want to invest in it.
Like buying a booth at a school fair
3 days, 10 days, or 30 days โ how long the song sits on the launchpad
Anywhere from 0% to 4% โ a small cut from every investment

Sarah the singer launches her new song "Moonlight". She picks 10 days and a 3% artist fee. Now people have 10 days to invest in it! During this time, fans choose which investment tier works best for them.
Think of the launchpad like three different sections in a cinema โ front row, middle, and back row. Each section has different rules!

Front Row โ All In!
Middle Row โ Safety Net
Back Row โ Fast Track
Enter your investment to compare all tiers
โ Tier 1 pays no fees at all โ artist fee only applies to Tier 2 & 3
| ๐ฅ Tier 1 | ๐ฅ Tier 2 | ๐ฅ Tier 3 | |
|---|---|---|---|
| Total Fees | $0.00 | $9.76 | $21.28 |
| Pool Amount | $100.00 | $90.24 | $78.72 |
| Backtrack Refund | N/A | $93.12 | $87.36 |
| Vesting Period | 24 weeks | 6 weeks | 1 week |
Think of graduation like a student finishing school. When a song's launchpad raises at least $5,000(across all tiers including vesting fees), it "graduates" and moves to the main platform where anyone can trade it freely!
There's no maximum โ people can invest millions if they love the song. But the minimum to graduate is $5,000.
If the song doesn't reach $5,000 by the end of its time window, it fails.
The launchpad closes and no new investments can be made
Everyone gets their full amount back, minus only the platform fee (1%)
Investors have 3 days to claim refunds. After 3 days they can still claim, but if artist relaunches, unclaimed investments get re-invested!
After the 3-day window, the artist pays $12 again and relaunches. Unclaimed investments get re-invested automatically.
Sarah's song didn't reach $5,000 in 10 days. All investors who claim get refunds. 3 days later, Sarah pays $12 again and relaunches for another 30 days. This time it succeeds! ๐
Artists can change their fee (0%-4%) at any time, but with two important safeguards:
Can't change it every day
New fee kicks in after 3 days
On Monday, Sarah changes her fee from 2% to 4%. The new 4% fee only applies from Thursdayonwards. And she can't change it again until next Monday. This protects investors from sudden fee surprises!
When a song successfully graduates, a token is created with these special properties:
All your tokens move from the Distribution Pool โ your Vesting Account
You immediately get the tokens you've already earned based on days passed
The rest stays in vesting and drips to you over your tier's vesting period
Every time you claim, you receive everything that has vested since your last claim.
| Tier | Vesting Period | Unlock Speed |
|---|---|---|
| ๐ฅ Tier 1 | 24 weeks (~6 months) | Slowest โ biggest reward |
| ๐ฅ Tier 2 | 6 weeks | Medium |
| ๐ฅ Tier 3 | 1 week | Fastest โ highest fees |
The song launches on Day 1. You're a Tier 1 investor (24-week vesting). You wait 3 days before claiming. On your first claim: all your allocation moves to your vesting account, you instantly receive 3 days' worth of tokens, and the rest drips over the remaining 21 weeks.
Once a token graduates, you can trade it freely! There are 3 types of swaps with fees (Platform + Artist):
| Swap Type | Description | Status |
|---|---|---|
| Case 1 "I invest $100 total" | Fees deducted from your $100, you get tokens with what's left | โ Fully Implemented |
| Case 2 "I want $100 worth" | You pay $100 worth of tokens + fees on top | โ๏ธ Backend Ready |
| Sell "I sell my tokens" | You sell tokens and receive USDC after deducting the fee | โ Implemented |
An artist can launch many songs, but they can only ever launch ONE Artist Tokenโ it's special and unique to them :
10, 30, or 100 days (vs. 3/10/30 for songs)
Only one Artist Token can ever exist per artist. It's their personal brand token.
The artist can start claiming accumulated fees from all launchpad transactions
No partial claims โ they get everything earned up to that moment in one go
Cannot claim fees while the song is still on the launchpad
All artist fees are stored in a single unified pool โ neat and organized
Sarah's song graduates. During the launchpad, $300 in artist fees accumulated. She can now claim all $300 at once. Next month, another $200 accumulates from AMM trading. She claims again and gets $200. ๐ฐ
| Rule | Details |
|---|---|
| ๐Non-Transferable | You can't send tokens directly to another person โ only buy/sell through the platform |
| ๐Multiple Investments | You can invest in the same song multiple times, even across different tiers |
| โฉ๏ธAll-or-Nothing Backtrack | If you backtrack from a tier, ALL your investment in that tier is refunded โ no partial exits |
