Three steps to bridge
Connect, pick the route, sign. No registration, no email, no files on our servers.
Connect your wallet
Any EVM wallet: MetaMask, Rabby, Trust Wallet, OKX, Coinbase, or WalletConnect. No sign-up — just your public address.
Pick the token and chains
What to bridge and from which chain to which. We'll show all available routes — cheapest, fastest, with time and fee estimates.
Sign the transaction
Your wallet prompts to sign (one or two transactions — sometimes an approve is needed first). After confirmation, funds arrive in 1-5 minutes.
One UI — every bridge
Route aggregator
We compare Stargate, Across, Hop, Connext, LayerZero and native bridges. Cheapest and fastest route selected automatically.
Non-custodial
We never hold your funds — every transaction is signed by your wallet directly. You're always in control.
Fast
Most bridges complete in 1-3 minutes. We show the exact ETA before you sign so you don't sit waiting blindly.
Transparent fees
See the full breakdown before confirming: gas, bridge fee, our 0.3% fee. No hidden fees along the route.
Common questions
What is a crypto bridge?
A bridge is a service that moves crypto from one blockchain to another. Your USDT on Ethereum can't be directly sent to an address on Polygon — you need a bridge that locks the token in the source chain and mints an equivalent amount in the destination. Rakoo Bridge aggregates major bridges (Stargate, Across, Hop, Connext, LayerZero) and automatically picks the cheapest and fastest route.
How is bridge different from swap?
Swap exchanges one token for another within a single chain (USDT→ETH on Ethereum). Bridge moves the same token across chains (USDT on Ethereum → USDT on Polygon). Under the hood the logic is often similar — and you can do swap-and-bridge in a single transaction via the same aggregator.
How long does a transfer take?
Depends on the bridge and chains: Across and Stargate finish in 1-3 minutes, Hop and Connext in 3-7 minutes, native Optimism/Arbitrum bridges up to 15 minutes. Before you confirm, we show the exact time and fee estimate for each route.
What's the fee?
It's a sum of: — source-chain gas (0.5-3 USD on Ethereum, cents on L2s) — bridge fee (typically 0.05-0.3%) — our 0.3% fee Before confirming you see everything in a single 'Total cost' line and can pick a cheaper route if available.
Is it safe?
We never hold your funds — every transaction is signed by your wallet directly. The bridges themselves are audited smart contracts used by millions of people. Still, cross-chain is always riskier than a same-chain transfer, so start with a small amount to test the flow.
What if my transfer is stuck?
Go to /find-tx, paste the tx hash from the source chain — we'll show the current status. If 30+ minutes passed and there's no finalization in the destination chain, contact the bridge's support (Stargate, Across — each has its own Discord/Telegram), they can manually relay the transaction.
Which tokens and chains are supported?
Most liquid pairs: USDT, USDC, ETH, DAI on Ethereum, Polygon, Arbitrum, Optimism, Base, BSC, Linea, Blast, Avalanche, Scroll. We also support transfers to/from Solana via native bridges. Full list is in the chain and token pickers.
