Base to Solana bridge routes compared
Across is the best Base to Solana bridge for USDC, Relay or deBridge are the ones to compare for ETH to SOL, and a Coinbase withdrawal skips the bridge entirely if your money is still on the exchange. Flat fees hurt small transfers and percentage fees hurt big ones, so the cheapest route for $50 of USDC isn’t always the cheapest for a large ETH swap.
| Route | Fee (provider’s own figures) | Speed | What lands on Solana | Good for |
|---|---|---|---|---|
| Across | “Cents”, per Across’s blog (14 April 2026) | 2 to 5 seconds, per Across | Native USDC | USDC of any size |
| Relay | 0% to bridge, 0.01% stablecoin swap, 0.06% major-token swap, plus a $0.02 flat fee and destination gas, per Relay’s fee docs | Shown in the quote | The token you pick | ETH to SOL, smaller amounts |
| deBridge | 0.001 ETH flat when sent from Base, plus 0.04%, per deBridge’s docs | Shown in the quote | The token you pick | Larger ETH to SOL swaps |
| Phantom swap | 0.85% Phantom fee plus a bridge fee folded into price impact, per Phantom’s help centre | Varies by provider | The token you pick | Small amounts, staying in one app |
| Jupiter Universal Deposit | No Jupiter fee; Base gas and up to 0.5% slippage, per Jupiter’s docs | Under 20 seconds from Base, per Jupiter | USDC | A Base wallet that won’t connect |
| Base-Solana bridge | Not listed in Base’s docs | About 300 finalised blocks, then a proof step | Bridged versions of Base tokens | Developers and apps |
| Coinbase withdrawal | Coinbase’s withdrawal fee | Coinbase’s processing time | Native USDC or SOL | Funds already on Coinbase |
Rhino.fi used to be the usual USDC backup, but it’s out of the table now. Its site says its services are offered on a B2B basis to enterprise clients, and the $0.50 cost on withdrawals to Solana sits in a help centre written for business clients, not a retail fee schedule.
Mayan isn’t in the table either, because Phantom’s swap already reaches it through LI.FI. If part of your money sits on BNB Chain too, our BNB Chain route guide covers that side. Holding USDT instead? Here’s bridging USDT to Solana.
Bridge USDC from Base to Solana with Across
Per Across’s blog, it uses Circle’s CCTP under the hood, so what lands is native, Circle-issued USDC. Its relayers front you the USDC on Solana straight away, which is why it arrives in seconds rather than minutes.
This matters because wrapped USDC is basically a different token with the same name, and if you end up holding it you’re stuck selling it into thin pools. Here’s how native and bridged stablecoins differ if you want the detail. It matters even more if you’re bridging to LP, because the main SOL-USDC pools on Meteora pair against native USDC. I LP on Meteora DLMM myself and post my results, losses included, on X. If that’s where you’re headed, start with the Meteora DLMM beginner’s guide.
You can use CCTP without Across, it’s just slower or dearer. Per Circle’s CCTP docs, a Standard Transfer from Base costs 0% and takes 15 to 19 minutes, and a Fast Transfer costs 0.013% and takes about 8 seconds.
You’ll need a Solana wallet and a little ETH on Base for gas. Phantom holds a Base address and a Solana address in one app; if you’re still choosing, see which Solana wallet to use, or set up Phantom first. Then:
- Type across.to yourself rather than clicking a search ad, since fake bridge ads are a known phishing route (our wallet security checklist has the rest). Connect MetaMask or Rabby for Base and Phantom, Backpack or Solflare for Solana.
- Set Base USDC to Solana USDC, enter the amount, and read the fee and the exact amount you’ll receive.
- Approve USDC spending (first time only), then confirm. You pay Base gas in ETH for both.
- Your USDC should show in your Solana wallet within seconds.
Once it lands, check the mint. Native USDC on Solana is EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v, and anything else is a different token. You can look it up on a block explorer like Solscan, and our explainer on token mints helps if two tokens sharing a name is new to you.
How to swap ETH on Base to SOL
For ETH to SOL you’re bridging and swapping in one go, so the SOL you actually receive is the number to compare.
- Open Relay’s bridge and connect your wallets.
- Pick ETH on Base to pay with and SOL on Solana to receive. Note the SOL you’d get after all fees.
- Get the same quote on deBridge in another tab.
- Take whichever gives you more SOL, then confirm.
On listed fees, the trade-off is Relay’s 0.06% (its docs count ETH and SOL as major tokens) plus $0.02 against deBridge’s 0.04% plus a flat 0.001 ETH. On a big swap, deBridge’s lower percentage can come out ahead. On a small one, that flat 0.001 ETH is most of your cost. Swap costs inside each quote (Relay lists DEX fees, swap impact and solver rebalancing separately) can change the result, which is why comparing the final SOL figure every time beats picking a favourite. The schedule is in deBridge’s fee docs if you want to check it.
If you’re moving a token without changing it, Relay’s percentage fee is 0%. You still pay the $0.02 flat fee and destination gas.
How to bridge Base to Solana in Phantom
Phantom’s swap screen can trade a token on Base for a token on Solana. Per Phantom’s help centre, it routes through LI.FI (which includes Mayan), Relay, deBridge and Garden.
The cost has four parts: the Base network fee, the bridge fee, the Solana network fee and price impact. Phantom folds the bridge fee into the price impact figure. To see it on its own, open swap settings, then Provider, before you confirm. On top of that comes Phantom’s 0.85% fee on most swaps.
That 0.85% is $8.50 on every $1,000. On $20 it’s pennies and the convenience is worth it. On anything bigger I’d use a dedicated bridge. If a pair won’t route, swap to USDC, ETH or SOL on Base first, then bridge that.
Jupiter Universal Deposit: no Base wallet connection
Jupiter’s deposit page lets you skip connecting a Base wallet. Per Jupiter’s docs (7 October 2026), you connect only your Solana wallet, pick Base, and send to the address shown. It arrives in your Solana wallet as USDC.
- Minimum: $3 from Base ($10 from Ethereum). Smaller amounts wait until they add up to the minimum.
- Time: under 20 seconds from networks other than Ethereum.
- Cost: Jupiter adds no fee. You pay Base gas, with up to 0.5% slippage on the conversion.
- Warning: only send on Base to the Base address. Jupiter’s docs say the wrong network risks losing the funds.
There’s also a Bridge & Swap option that compares routes across 11 networks, powered by GUM and deBridge. If your Base wallet connects fine, Across is still simpler for USDC. Universal Deposit is the fallback when it won’t, like some exchange-linked or smart wallets. The rest of Jupiter is in our Jupiter walkthrough.
The official Base-Solana bridge (Coinbase and Chainlink)
The official Base-Solana bridge is built for apps and developers. It won’t turn Base ETH or Base USDC into native SOL or Circle’s native Solana USDC, so most people moving money should use Across, Relay or deBridge instead.
Base launched it on mainnet on 4 December 2025. In its launch announcement, Base said Coinbase and Chainlink CCIP node operators each verify every message independently. Per Base’s bridge docs, a Base to Solana transfer waits about 300 finalised blocks, then needs a Merkle proof before it executes on Solana. The only consumer interface the docs list is Terminally Onchain, a terminal-style app where you type bridge commands. The docs don’t list fees.
What it moves: SOL and SPL tokens to Base and back, and Base-native tokens to Solana as bridged versions. Base said apps like Zora, Aerodrome, Virtuals, Flaunch and Relay would build it in.
I wouldn’t go looking for it, because there’s no simple consumer app for it yet and it doesn’t give you the native tokens Solana apps use. If an app you already use builds it in, fine.
Coming from Coinbase? Skip the bridge
Base is Coinbase’s network, so a lot of Base money starts on Coinbase. If yours is still there, there’s no reason to withdraw to Base and then bridge. Coinbase supports USDC on Solana (Circle lists it among the exchanges that do), and SOL obviously withdraws on Solana, so just pick Solana as the network.
In the send screen, choose Solana, paste your Solana address (not your 0x Base address) and send a small test first. Our step-by-step for moving SOL from Coinbase to Phantom has the screens.
Already holding USDC on Base in your own wallet? Coinbase’s status page lists Base and Solana among its USDC networks, so sending it to your Coinbase account on Base and withdrawing on Solana also works. Compare Coinbase’s withdrawal fee against an Across quote first.
How to bridge Solana to Base (Phantom, Across, Relay)
It works the same way in the other direction. In Phantom, pick a Solana token like SOL or USDC to pay with and a Base token to receive. Check Provider in swap settings, remember the 0.85% fee, and pay the Solana network fee in SOL.
Across, Relay and deBridge all work this way too, with the same fee schedules. deBridge’s flat fee is 0.015 SOL when the order starts on Solana. You’ll want a little ETH on Base afterwards for gas. Heading to Ethereum mainnet instead? See our Solana to Ethereum guide.
Arrived on Solana with no SOL?
Landing with USDC and zero SOL is common. Every Solana transaction needs SOL, and holding a new token needs a token account with a small refundable deposit.
Phantom’s gasless swaps fix this. Per Phantom’s help centre, they kick in automatically when the swap is at least $0.30, the token you receive is verified and you use the standard swap flow. They don’t work with a manual priority fee or exact output. A flat fee comes out of the token you’re swapping instead of SOL, so you can swap a few USDC into SOL and you’re unstuck.
The other option is to bridge a small slice as SOL first through Relay or deBridge, then send the rest as USDC. That’s what I’d do with a bigger amount, because a wallet with zero SOL can’t move its tokens without a workaround like gasless swaps.
Once you’re set, putting it to work in Solana DeFi is the next read, and our Solana academy starts from zero if wallets, tokens and fees are still new.
FAQ
What is the best Base to Solana bridge?
For USDC, Across, because it delivers native USDC in seconds for cents. For ETH to SOL, compare Relay and deBridge on the day. Neither wins every time.
What is the cheapest way to bridge USDC from Base to Solana?
By their own fee docs, Across and Relay come out cheapest for USDC. Phantom’s 0.85% fee puts it behind on most amounts. If your USDC is on Coinbase, withdrawing on Solana skips the bridge.
How do I convert ETH on Base to SOL?
Use a bridge that swaps along the way, like Relay or deBridge, with ETH on Base in and SOL on Solana out. deBridge’s flat 0.001 ETH fee suits bigger swaps; Relay’s $0.02 flat fee suits smaller ones. Compare the SOL each quote gives you.
How long does it take to bridge from Base to Solana?
Seconds on Across for USDC, and under 20 seconds from Base on Jupiter’s Universal Deposit, per Jupiter. A CCTP Standard Transfer takes 15 to 19 minutes. The official Base-Solana bridge waits about 300 finalised blocks before its proof step.
Can I send USDC from a Base wallet directly to a Solana address?
No. Base uses 0x addresses and Solana uses a different format. You need a bridge, Jupiter’s Universal Deposit or an exchange that withdraws on Solana.
Should I use the official Base-Solana bridge?
Probably not directly. It’s aimed at apps and developers, and it won’t give you native SOL or native Solana USDC from Base ETH or USDC.
Do I need SOL before bridging to Solana?
Not to start the bridge, but you’ll need it straight after for fees and the token account deposit. If you arrive with none, Phantom’s gasless swaps can turn a few USDC into SOL.
How do I bridge from Solana to Base in Phantom?
Open Swap, pick a Solana token to pay with and a Base token to receive, and check the provider fee in swap settings before you confirm. Phantom’s 0.85% fee applies on top, so compare Across or Relay for larger amounts.
