Memecoin launchpad · Miden testnet

Memecoins, builtnatively on Miden.

Every token starts with 1B supply on the same bonding curve. Each buy or sell is a note you send from Bread that fills or refunds in full. When the curve sells out at 4.2 USDCx, the token graduates into locked MintrisePool liquidity.

Supply: 1,000,000,000

Drag · USDCx raised, 0 to 4.20

Price multiple ((1.68 + R) / 1.68)², where R is USDCx raised and 1.68 is the virtual reserve. At 4.2 the curve is sold out, the token graduates, and MintrisePool opens at that price, so there is no jump.

01The curve

One curve. The same rules for every token.

Supply, curve and graduation point are fixed. The creator picks a name, a ticker, an image, a tax and whether buybacks are on. Nothing else is up for negotiation, and nobody can pull the liquidity.

02Two-step notes

Send, then claim.

Every order is two steps: send a note, then claim the result into Bread. If it can't fill in time or within your slippage, you claim a full refund instead.

Public and checkable

Curve and pool accounts are public on Miden, and every fill and refund pays out as a public note anyone can check.

Proven, not trusted

Miden transactions are proven with zero-knowledge proofs, so the curve's rules are checked by the network, not by trust in us.

03Fees

Every fee, shown before you trade.

The same fee applies on every buy and sell. The creator tax is fixed at launch and shown before you trade. Both still apply after graduation.

04Questions

Good questions.

When can I use it?: Testnet comes first, at testnet.mintrise.fun. The waitlist gets in first. Mainnet follows once the curve and claim flow have been tested in public.
Why a Miden address instead of an email?: Mintrise lives in your Bread wallet, so your address is all we ask for. It is public by design; we never ask for a seed phrase or a signature to join.
Which wallet do I need?: Bread, the wallet for Miden. It holds your notes and approves each step of an order.
What does "graduate" mean?: Each token starts on a bonding curve. When the curve sells out, the token graduates: liquidity seeds a MintrisePool and stays locked there. There is no withdraw, for anyone, including the creator.
What do I pay?: A 1% trade fee on every buy and sell, plus the token's creator tax (1 to 10%, minimum 1%, set at launch and immutable, shown before you trade). Both apply before and after graduation. Buys in the first 3 seconds after a launch also pay an anti-sniper tax. Launching a token costs 0.0005 USDCx.
What do I trade with?: On testnet, USDCx. On mainnet, bridged ETH.
