You are reading the Arc Testnet docs. This is a test network: USDC here has no value, it comes free from a faucet, and the chain can be reset at any time by its operators. Nothing you launch or buy here is worth money. Switch the network selector to Stable for the live deployment.
Getting started: how to buy
New here? This is the whole path from nothing to holding a coin, in five steps. It takes about ten minutes the first time and seconds after that.
Install MetaMask, Rabby, or any EVM wallet. On mobile, use the wallet's built-in browser and open mintd.fun inside it, that saves a lot of connection headaches. Write your seed phrase down on paper. Nobody from mintd will ever ask you for it.
Click Connect wallet at the top of this site and approve the network prompt. That adds Stable Mainnet (chain 988) for you. If you would rather add it by hand: RPC https://rpc.stable.xyz, chain ID 988, currency USDT0, explorer stablescan.xyz.
USDT0 is both the money and the gas on Stable, so you need some before anything else works. Open the Bridge tab, pick whichever chain your funds are on, and follow it through. Most transfers land in seconds. Bring a little extra for gas; fees here are a fraction of a cent, so a dollar goes a very long way.
USDC is both the money and the gas on Arc, so you need some before anything else works. It is free on testnet: open faucet.circle.com, paste your address and claim. The faucet gives 20 USDC per address every two hours, which is plenty, since gas costs a fraction of a cent and launching a token costs 1 USDC. There is no bridge to a testnet and you should never send real funds here.
Browse Discover, or paste a contract address into the search box if someone shared one with you. Always match the full address, not just the ticker, since anyone can launch a coin with any name. Every token page shows its market cap, 24h volume, liquidity and a live chart.
On the token page, enter a USDT0 amount and hit Buy. Your wallet will ask you to confirm, and the tokens arrive in the same transaction. Selling is the same flow on the Sell tab. There is no approval step for buying with USDT0 and no minimum size.
A few things worth knowing before your first buy. Every coin here trades on a bonding curve, so the price moves as people buy and sell, and a large order moves it more than a small one. Check the quote before confirming. Liquidity is thin on brand new coins, which means a big buy can fill several percent worse than the displayed price. Nothing on this site is reversible, and no one can undo a transaction for you.
Something not working? If the site says wrong network, switch your wallet to Stable. If a transaction fails with a gas error, you need a little more USDT0 in your wallet. If balances look stale, hard refresh the page. If your wallet will not connect on mobile, open mintd.fun from inside your wallet's own browser rather than Safari or Chrome.
Overview
mintd.fun is a full DeFi platform on Stablechain (chain 988), where the native gas token is USDT0. It combines a memecoin launchpad, a swap aggregator, MintSwap (our own Uniswap V2 fork), yield farms, a zap tool, the MINTR reserve token, and an onchain MINTD buyback-and-burn. The platform token is $MINTD.
mintd on Arc is a memecoin launchpad on Arc Testnet (chain 5042002), where the native gas token is USDC. Arc had no DEX when we arrived, so we deployed one: a full Uniswap V3 stack plus MintSwap, our own Uniswap V2 fork. On top of that sit the launchpad, the MINTR reserve token, the token locker and the Furnace. The gold engine, the farms and the $MINTD token are Stable-only for now, so those tabs are hidden here rather than shown broken.
Launchpad
Launching a token costs a small creation fee (currently 1 USDT0). Your token is a fixed 1,000,000,000 supply, immutable ERC-20 with no owner, taxes, blacklist, buy limits, or same-block restrictions. The entire supply goes straight into a single-sided token/USDT0 Uniswap V3 position (1% fee tier) in the launch transaction, so trading is live from block one. The liquidity position NFT is owned by the launchpad contract, which has no code path to withdraw liquidity: it is locked forever, verifiable onchain. You can add an image, banner and socials, all stored onchain in the token's metadata. An optional "dev buy" lets you buy the first tokens in the same launch transaction.
Every launch here starts at the same valuation: 1,000,000,000 tokens at $0.000003 each, a $3,000 starting market cap, fixed in dollars rather than floating with a volatile gas token. Nobody gets a cheaper entry than anybody else.
Bonding curve & graduation
Because the whole supply sits in a one-sided Uniswap V3 range, each token trades on a constant-product bonding curve from its first block: buying raises the price along the curve, selling lowers it. There is no separate "curve then migrate" step, the curve is the locked DEX pool. A token shows "graduated" once its pool holds 7,000 USDT0, which is a cosmetic milestone, the liquidity never migrates or unlocks.
Fees
Every trade on a launched token pays the Uniswap 1% pool fee. That fee accrues to the locked position and is split: creators claim 90%, the platform takes 10%. Anyone can trigger a claim, which pays both shares straight to their wallets. 100% of the $MINTD token-side fees are burned. There is a flat creation fee per launch and a small platform fee on some other actions.
Every trade on a launched token pays the Uniswap 1% pool fee. That fee accrues to the locked position and is split three ways, on chain, by the launchpad itself:
| DESTINATION | SHARE OF THE POOL FEE | SHARE OF TRADE VOLUME |
|---|---|---|
| Creator | 80% | 0.80% |
| Buyback and burn | 16% | 0.16% |
| Operations | 4% | 0.04% |
Anyone can trigger a claim, and the shares always go to the same three places no matter who calls it. You can read the split off the contract: creatorShareBps is 8000 and buybackShareBps is 8000 of the remaining 20%.
Dev buy cap
A creator may buy their own token in the launch transaction, but no more than 5% of supply. On the launch curve that works out to about 159.47 USDC, and the launch page shows the exact figure before you sign. Send more than that and the launch reverts rather than being silently trimmed.
The cap is enforced on the number of tokens actually received, not on the amount spent, so it cannot drift as the price math changes.
What this does not do. It bounds the buy the launchpad performs, and nothing more. A creator can buy more in the very next transaction, from another wallet, or from a contract in the same transaction. It is a guardrail against the default path being abused, not a promise about how much of a supply a team ends up holding. Always check holder distribution yourself.
Tokenomics
The protocol keeps 20% of pool fees. Of that, 80% is earmarked for buying and burning a platform token, and 20% funds infrastructure and the team. That works out to 16% and 4% of every pool fee respectively, and both destinations are addresses stored in the launchpad, so the routing is verifiable rather than a promise on a web page.
Being straight with you about the current state: there is no mintd token on Arc yet. Until one exists there is nothing for a buyback to buy, so the buyback address currently points at the same wallet as operations, and 100% of protocol fees fund operations today. When a token launches here, the buyback share will be repointed at a contract that can only do one thing with what it receives: buy that token and send it to the dead address.
The intended end state is a buyback that runs as a time-weighted average, executing a slice at a time on a fixed schedule rather than in one block, with a permissionless trigger and no owner, no withdrawal and no pause. That contract is written but not deployed. Until it is, do not treat the buyback as live, because it is not.
Editing your token page
Launch metadata is written onchain and is immutable, so it can never be edited in place. Instead, creators can publish an overlay through the meta registry contract: connect the wallet you launched with, open your token's page, and an "Edit page" button appears. You can update the bio, X, Telegram, website, and the logo and banner images. The registry checks against the launchpad that you really are that token's creator, so nobody else can touch your page. Updates cost only gas, take effect immediately, and can be changed or cleared any time. The original launch metadata stays onchain forever underneath.
Swap
The Swap tab routes any token on Stable through the canonical Uniswap V3 deployment. It quotes every fee tier plus two-hop routes through USDT0 and picks the best output, with 1% slippage protection. Common tokens (USDT0, WgUSDT, MINTD) are pinned; any other token can be added by contract address.
The Swap tab routes any token on Arc through the Uniswap V3 deployment we put there. It quotes every fee tier plus two-hop routes through USDC and picks the best output, with 1% slippage protection. USDC and MINTR are pinned; any other token can be added by contract address.
Pools
MintSwap is our own Uniswap V2 deployment. Liquidity providers earn 0.3% of every swap through their pool, proportional to their share. Everything pool-related now lives on the Earn tab: trading-fee pools with one-click zap in, your LP positions with add and remove liquidity, and the farms below. Typing one side of a manual add auto-fills the other at the live pool ratio, so deposits cannot be rejected for being mismatched.
Earn / farms
Farms let you stake MintSwap LP tokens to earn $MINTD streamed every second, on top of the 0.3% trading fees your LP already earns. Each farm shows its live APY (reward APR plus fee APY), TVL, rewards per day and how long the reward period runs. The USDT0/WgUSDT farm is a stable/stable pair with near-zero impermanent loss. APYs are high while TVL is low and fall as more people stake, that is just math, not a guarantee.
Zap
Zap lets you enter a farm with USDT0 only, in one flow that also stakes the LP for you. For the USDT0/WgUSDT pool it wraps part of your USDT0 into WgUSDT at 1:1, so there is zero slippage. For other pools it routes the swap through canonical Uniswap's deep liquidity to avoid price impact, then pairs and stakes. A price-impact guard blocks any risky zap before it happens.
MINTR
MINTR is a fully-backed reserve token. Its contract holds a USDT0 reserve and prices MINTR at reserve divided by supply (the backing per token). You buy with USDT0 (mints MINTR) and sell MINTR back (burns it, pays USDT0). Buy and sell each take a small tax that stays in the reserve while tokens are burned on sale, so the backing per token is mathematically non-decreasing, and MINTR is always fully backed 1:1. Honest note: the contract price only rising is not a promise of profit. Your gains come from other people's volume, it is a bonding curve (you redeem at the current backing minus tax, and mass exit shrinks the reserve), and the team can never withdraw the backing. A MintSwap MINTR/USDT0 pool also exists so arbitrage keeps the market price near the contract price; always redeem at the contract for the true value.
Mintd Gold ($MGLD)
$MGLD gives you gold exposure onchain without custody, paperwork or market hours. It is a collateralized debt position: you lock USDT0 as collateral and mint $MGLD against it, priced by RedStone's onchain gold feed (XAUt/USD). Every $MGLD in existence is backed by more USDT0 than it is worth, which is what keeps the system solvent.
The rules: you must stay above 150% collateral to mint, and if gold rises enough that your position falls below 130%, anyone can liquidate part of it, repaying your debt and seizing collateral at a 10% discount. A 0.5% mint fee is charged in collateral and sent to the BuybackBurner, so every $MGLD minted buys and burns $MINTD. Repaying debt and withdrawing collateral can never be paused, and there is no admin function anywhere that can touch your collateral. Oracle guards reject stale prices and implausible jumps, and minting pauses rather than using a bad price. There is also a small MGLD/USDT0 pool so you can buy it without opening a position, though minting has no slippage and no limit while the pool is thin.
Honest note: $MGLD tracks a gold price feed. It is not redeemable for physical gold and gives you no claim on any metal. If gold rises against your position you can be liquidated and lose collateral.
Locker
The Locker lets anyone lock any token on Stable until a date they choose: teams locking supply, LPs locking LP tokens, holders proving they are not selling. Locks can be extended but never shortened, only the lock owner can withdraw and only after the unlock time, and there is no admin path to locked tokens. Every active lock is public, with total value locked and per-lock details, so anyone can verify a project's claims. A small flat fee applies per lock.
Separately, Uniswap V3 liquidity positions can be locked permanently in a dedicated locker contract that keeps trading fees claimable by the position's beneficiary forever. The liquidity itself can never be withdrawn by anyone, including us. This is the same guarantee the launchpad gives its own pools, made available to positions created outside it.
BridgeFaucet
Everything here trades in USDT0, the gas token on Stable. The Bridge tab routes you to Relay, an intent network in Stable's ecosystem, with your source chain preselected. Solvers deliver USDT0 on Stable and settle the source side themselves, so most transfers land in seconds and Solana works natively. Ethereum, Base, Solana, Arbitrum and 80+ other chains are supported. mintd does not run a bridge and never takes custody of your funds.
There is no bridge to Arc Testnet, and there should not be: testnet USDC is not real money and nothing here is worth bridging for. Get it free from faucet.circle.com, which hands out 20 USDC per address every two hours. That is enough for twenty launches or a great deal of trading, since gas costs a fraction of a cent. Never send funds from a mainnet to this chain.
Buyback & burn
MINTR's platform fee accumulates as USDT0 in a permissionless BuybackBurner contract. Anyone can trigger it: the contract market-buys $MINTD with the collected USDT0 and sends it straight to the dead address. It has no owner and no withdrawal, its only possible action is to buy and burn MINTD. This turns MINTR trading volume into real, verifiable MINTD buy pressure and supply reduction.
The design is a contract that holds collected USDC and can do exactly one thing with it: buy the platform token and send it to the dead address. No owner, no withdrawal, no pause, and anyone can trigger it. It is not running on Arc yet, because there is no platform token here to buy. See Tokenomics above for what is actually happening to protocol fees today.
Separately, the Furnace is live and does work: send any token to it and it is burned to the dead address, with running totals kept in contract storage so the record survives the RPC pruning its logs.
$MINTD
$MINTD is the platform token, launched through the launchpad itself as token #0 with permanently locked liquidity. Its value is tied to platform activity: 100% of its token-side trading fees are burned, and the buyback-and-burn converts platform revenue into MINTD buys and burns. The live burn counter on the homepage reads the dead-address balance directly.
Security & disclaimers
All launched tokens are immutable with no owner or mint function; launchpad liquidity is locked with no withdraw path; the buyback contract has no admin; MINTR's backing can never be withdrawn by the team. That said, all of this code is unaudited. Locked liquidity and verified source protect against rug-pulls, not against bugs. Crypto is risky, prices go up and down, and nothing here is financial or legal advice. Verify every contract on stablescan.xyz and do your own research before using real funds.
Specific to Arc: this is a test network. The chain can be reset, tokens here are worth nothing, and the launchpad owner is a plain deployer key rather than a multisig. Treat everything on it as a demo. The launchpad, MINTR, the locker, the V3 position locker, the metadata registry and the Furnace are all source-verified on testnet.arcscan.app; the Uniswap and WETH contracts underneath are stock builds from npm and are not verified there.
$MINTR
only goes up.
MINTR is 100% backed by a USDT0 reserve. Every buy and sell pays a small tax that stays in the reserve while tokens are burned, so the backing per token can only rise. Buy and sell straight from the contract at the backing price.
Mintd Gold
$MGLD
Lock USDT0, mint $MGLD, hold gold exposure onchain. Every $MGLD is overcollateralized by USDT0 sitting in the contract and priced by RedStone's onchain gold feed. Every mint fee buys and burns $MINTD.
Mintscreener.
Every coin launched through mintd on this chain, priced from its own pool. Charts are built from onchain swaps, not an indexer, so a coin appears the moment it trades.
The furnace.
Send any token to the dead address and it is gone for good. Supply drops, nobody can spend it, and there is no key anywhere that reverses it. Works with any ERC-20 on Stable, whether or not it launched here.

One transaction puts your fixed 1B supply on a bonding curve inside a locked USDT0 pool on Uniswap V3, tradable instantly. Markets open at 3,000 USDT0 and graduate at 7,000 USDT0 in the pool. The position belongs to the factory contract, which has no code path to withdraw it. Verify it onchain. Every trade pays a 1% fee and – of it is yours to claim, any time, forever.
Token details Creation fee: – USDT0
An agent that cannot pick a price.
Each vault holds one Uniswap V3 position. The agent proposes timing and nothing else: the vault derives every value-carrying number from a TWAP, so a stolen keeper key can waste gas but can never choose an execution price, a venue or a range.
Run your own agent
–Testnet only. Both tokens are worthless and freely mintable, which is the point: the pool is deep enough that what you are testing is the agent, not the pool.
Vaults
–Who has actually held.
Every $MINTD balance on Stable, measured continuously since launch. This scores how long you have held, not just what you hold today, so buying in right before a snapshot earns nothing.
Standings
–How this number is made
No part of this is estimated or curated. Every figure comes from Stable's own transaction logs, and the whole thing is reproducible by anyone who wants to check it.
An indexer walks all Transfer logs for the $MINTD contract, 500 blocks at a time, from the token's first block onward. A window that fails is retried; if it cannot be read, the run aborts rather than skipping it, because a gap makes every number below quietly wrong instead of visibly broken.
After each pass, every balance is added up and compared to the token's totalSupply. They must match exactly. The indexer refuses to advance if they do not, so the board is never built on a partial read. It currently reconciles across – transfers.
Rather than a snapshot, the indexer accumulates balance x blocks held for each address. Dividing by the tracked window gives a time-weighted average: what you held on average, across the whole period. Holding 1M for the full window scores the same as holding 2M for half of it.
score = min(time-weighted average, balance now)
Each half blocks a different way of gaming it. Without the average, buying the day before a snapshot earns as much as holding for months. Without the current balance, people who already sold still score: on the first run, two of the ten highest by duration held nothing at all, and – addresses had a positive duration score with an empty wallet. Taking the smaller number closes both.
The liquidity pool, the launchpad, farms, lockers, the burn address and the project's own wallets are all removed. Anything holding contract code is excluded. That is deliberately blunt and would also exclude a smart-contract wallet belonging to a real person.
Why it starts where it does. Stable's RPC keeps only about four to five days of logs and has no archive, so holding history cannot be reconstructed after the fact. Recording began at block –, which was the token's first block and was still readable with roughly a day to spare. Nothing earlier can ever be added, by us or anyone.
Updated every ten minutes. Score changes as you buy, sell, or simply keep holding, and as the tracked window lengthens.
What this is not
A measurement, not an entitlement. It records what has already happened on chain. There is no token on Arc, no supply decision has been made, and Arc mainnet is not publicly live. Nothing here promises you anything, no amount is committed, and no date is set. If that changes it will be said plainly, rather than implied by a dashboard.
Percentages are shares of the tracked total, which moves as other people buy and sell. Your share can fall while your own holding is unchanged.
Pending fees
Unclaimed Uniswap V3 pool fees across every token launched on mintd. Claiming pays each token's creator and the protocol recipient directly; the caller only pays gas.
