How bonding-curve launches work on XAUConnect

Written by XAUConnect Labs · Reviewed against live product behavior · Updated August 2026

A bonding-curve launch sells tokens against a price function as buyers come in, instead of seeding a classic constant-product pool on day one. XAUConnect’s Launchpad offers this as a second launch type: the wallet calls `createLaunch` on the Launchpad contract with name, symbol, and metadata URI, plus the native launch fee — not `createToken` on TokenFactory.

Curves can be fairer than a hidden presale. They can also be confusing exits if nobody understands when (or whether) liquidity migrates to a normal AMM. Read the launch type before you sign, whether you are the creator or the first buyer.

Standard versus curve

Standard: entire supply mints to the creator, who must LP. Curve: distribution is tied to the curve’s buys. Creator convenience and buyer fairness are different. If you need a simple swappable ERC-20 with locked LP, standard plus LP lock is easier to explain and easier for aggregators to route.

What buyers should ask

Where is the curve contract? When does it graduate to a pool XAUConnect can route? Who can pull leftover parameters? If those answers are missing, treat it as higher risk than a locked Uniswap-style pair you can already quote.

What creators should not promise

Do not call it a fair launch if team wallets still have special exits. Do not promise aggregator support during a phase where only the curve contract trades. Point people at the correct UI for that phase, then at Swap once a normal pool exists.

After graduation

Once a regular pool exists, the first-swap-after-launch checklist applies: second wallet, buy and sell, publish hashes. Until then, XAUConnect Swap may honestly return no route.

Fees

Launch fee is still native coin through FeeCollector. Curve trades may have their own fee schedule. Disclosed fees are fine. Surprise fees are how you get compared to tax tokens in our education pages.

Do not market a curve as a Uniswap pool

If Swap returns no route, you are probably still on the curve. Send buyers to the curve UI or wait for graduation, then run the second-wallet round-trip on XAUConnect. Calling it “already tradeable everywhere” during the curve phase is how people buy clones on a real AMM that reused your ticker. Creators: if you wanted the simple story, use TokenFactory plus locked LP. Curves are a distribution choice with extra sentences you must be willing to write.

Graduation is a product event

Announce when the AMM pool exists and paste that pair’s token address into the Swap instructions. Until then, “buy on XAUConnect” may be a lie. Curves that never graduate leave buyers in a custom contract aggregators never indexed. Know which story you are telling.

Frequently asked questions

Which button in the wizard?

Launch type: bonding-curve versus standard. The review screen should match the function you expect (`createLaunch` vs `createToken`).

Is a bonding curve safer for buyers?

It can reduce stealth allocations. It does not remove contract risk or the need to understand graduation. Safer is “understood,” not “curved.”

Can I swap a bonding-curve token on the main Swap page immediately?

Only if a routable pool already exists. Many curves trade only against their own contract until graduation.

Solana bonding curves?

Solana has its own curve culture on other venues. This Launchpad path is EVM `createLaunch`.
