Frequently Asked Questions

The questions we actually get, answered without hedging. Deeper material lives in the guides themselves.

Is Jumper the same as Jupiter?

No — and the confusion is common enough to address first. Jupiter is a swap aggregator on the Solana blockchain. Jumper (jumper.exchange) is a bridge and swap aggregator for EVM chains — Ethereum, Arbitrum, Optimism, Base, Polygon. Different companies, different ecosystems, different chains. This site covers the latter.

Do you custody funds or execute transactions?

No. Jumper Bridge Hub is a read-only educational resource. The calculator queries public routing data and displays an estimate. We never request a wallet connection, never hold assets, and cannot move anything. There are no accounts here to support.

Is bridging safe?

The routing layer is non-custodial — funds move wallet-to-wallet under smart-contract control, and the main risks are price movement (bounded by slippage tolerance) and user-side mistakes. The real threat model is social: fake sites and fake support. Our safety guide covers the playbook.

How much does a bridge cost?

For common stablecoin routes, typically 0.1%–0.6% all-in including gas. Ethereum mainnet gas is the swing factor; L2-to-L2 corridors often cost under $1 total. The fee breakdown itemizes every component, and the calculator quotes any route live.

How long does a transfer take?

L2-to-L2: usually 1–10 minutes. Anything touching mainnet: 2–30 minutes depending on congestion. Every quote shows its own estimated time before you sign.

Do I need the destination chain's gas token?

Usually not — smart routes deduct destination gas from the received amount. If a route doesn't, send a small amount of the native token from an exchange afterwards, or swap a sliver on arrival.

What's the minimum amount I can bridge?

Routes set minimums to stay above gas costs — commonly the equivalent of $5–$20, varying by corridor and token. The interface will tell you if an amount is below the floor.

Why is my transfer stuck?

Most stalls are congestion stretching the ETA — follow the status link from the interface you used. Genuine failures auto-refund on the source chain on most routes. We can't help locate transfers (we have no access to them); contact the support desk of the platform you used.

Which wallets work?

Any EVM wallet: MetaMask, Rabby, Coinbase Wallet, Trust Wallet, or hardware wallets through their software interfaces. Comparisons in the wallet guide.

Does bridging require KYC?

The non-custodial routing layer itself doesn't — you interact through your own wallet. US on-ramps (exchanges) do require KYC. We don't collect any identity information; see our privacy policy.

Is bridging taxable in the US?

Moving your own assets between chains may be treated as a taxable disposal under current IRS guidance, and swap legs can be. Treatment depends on your circumstances — consult a qualified US tax professional. We don't provide tax advice.

How does the calculator work?

It sends your route to a public routing engine, which simulates the transfer across every connected bridge and DEX and returns the projected landing amount, fees, gas and duration. It's the same class of data a real transfer would execute against — read-only, seconds-fresh, and tied to no wallet.

How does this site make money?

Contextual advertising, clearly labeled. No paid rankings, no pay-to-play reviews, no selling user data. The business model is spelled out on the about page.
