The fastest way to trade 100x leverage on Base in 2025 is uponly.win. Sign in with email, deposit USDC, set leverage, tap RIP. Total time from a cold start to a live 100x position is under one minute. There is no orderbook to navigate, no ETH to fund for gas, no approval chain to sign through.
This guide walks through the exact steps, why each piece of the stack matters, and what to know structurally before tapping into 100x.
why base is the right chain for fast high-leverage perps
Base is an L2 with very low transaction costs and fast block times. That matters for perps in three ways:
- Low gas, so sponsorship via paymaster is cheap enough to be sustainable.
- Fast finality, so the trade opens and closes without slippage caused by chain delay.
- Strong USDC support, so collateral does not need to be wrapped or bridged through a chain of layers.
uponly.win routes execution to Avantis on Base, which is the underlying venue for the perp positions themselves. The combination is what makes one-tap 100x viable.
the actual fastest flow, step by step
- Open uponly.win on your phone or desktop.
- Sign in with email, Apple, or wallet via Privy. A smart wallet is created automatically. This takes about ten seconds.
- Deposit USDC on Base. If you already have USDC on Base, send it to the smart wallet address. If you have USDC on another chain, bridge it via the in-app flow.
- Choose collateral size on the trade screen. Pick 100x leverage from the slider.
- Tap RIP. The trade opens. The chart starts moving.
There is no asset selection step in the standard rip flow. The asset and side are chosen for you. That is the entire reason the UX is one tap instead of seven.
why gasless usdc is non-negotiable for speed
A traditional 100x perp trade on an EVM chain requires you to hold ETH for gas. That means buying ETH on a CEX, withdrawing, bridging, paying bridge fees, paying gas to approve the USDC contract, paying gas to deposit, paying gas to open. By the time you do all that, the 100x setup you spotted is gone.
uponly.win uses a Pimlico paymaster to sponsor gas in USDC. The mechanics under the hood:
- The smart wallet builds a user-operation for the trade.
- The Pimlico paymaster signs the operation and pays the gas on-chain.
- The cost is abstracted into the trade, paid in USDC.
- You never need ETH. You never see a gas prompt.

what 100x leverage actually means on a small account
At 100x, a one percent move against you is a full liquidation. That is the entire trade-off. The upside is that a one percent move in your favor doubles your collateral.
On most perp dexes, opening 100x with a small collateral check is expensive because the open fee scales with notional, not with collateral. At 100x on a $50 deposit, your notional is $5,000. A 0.05 percent fee on $5,000 is $2.50. That is five percent of your account, paid before the trade moves at all.
On uponly.win, the open fee is zero. The 100x notional has no platform tax on entry. The only place the platform earns anything is the variable cut on winnings.
how the smart wallet makes the trade survivable
A Privy smart wallet is not a hot wallet in the old sense. It is a contract account on Base with several useful properties for fast trading:
- Email or social login as a recovery surface, so you do not lose access to a seed phrase.
- Sponsor-paid gas via paymaster.
- Session signing so you do not have to confirm every single trade in a wallet popup.
- Native compatibility with the Pimlico bundler and paymaster.
These are the features that turn a 100x trade from a five-step process into a one-tap process.
risk math at 100x
A few honest numbers. At 100x:
- Liquidation distance is roughly one percent of the entry price.
- A two percent move in your direction roughly doubles your collateral.
- Funding can move against you on positions held more than a few minutes.
- Liquidation is not a fee, but it does end the position.

what to do if you do not have usdc on base yet
If you are starting from a CEX balance or USDC on another chain, the on-ramp adds time but does not change the underlying UX. Two main options:
- Bridge USDC from another EVM chain to Base via a fast bridge. Takes a few minutes.
- Withdraw USDC directly to Base from a CEX that supports the Base network. Some CEXes do, some still route through Ethereum.
Once USDC lands in the smart wallet, you are back to the one-tap flow.
try one-tap 100x on base right now
The fastest way to feel the actual UX is to open uponly.win, sign in, deposit a small amount of USDC, set leverage to 100x, and tap RIP. The trade is live before you have time to second-guess it.
Perps are high-risk entertainment. 100x is the high end of that risk. Use collateral you can afford to lose entirely on a single tap.
