Bridging assets between Binance Smart Chain (now called BNB Chain) and Solana lets traders access each network’s benefits – for example, moving BNB (the native coin of BNB Chain) into Solana’s ecosystem (DeFi, NFTs, etc.). A bridge connects these blockchains so tokens on one chain can be sent to the other.
In a Solana bridge, the asset on BNB Chain is locked or burned, and an equivalent token is minted on Solana. This unlocks Solana’s high speed and low fees for your BNB Chain assets. For instance, bridging BNB (on BNB Chain) into SOL (the native token of Solana) involves locking BNB on the source chain and receiving SOL on Solana.
How Cross-Chain Bridges Work
Bridges use smart contracts to transfer value across chains. Typically, when you bridge BNB Chain → Solana, the bridge will lock your BEP-20 token (e.g. BNB or a BSC-based stablecoin) on BNB Chain and then mint a wrapped version on Solana. Conversely, moving assets back (Solana → BNB Chain) burns the Solana token and unlocks it on BNB Chain. Major bridges employ different models: for example, Wormhole’s Portal Bridge uses a lock-and-mint method (locking tokens on BSC and minting wrapped tokens on Solana), while Allbridge uses on-chain liquidity pools to swap assets across chains. Aggregators like Symbiosis automatically route your transfer through the best available bridge or swap route.
Step-by-Step: Bridging BNB Chain → Solana
The basic process to bridge funds is:
Choose a Bridge/Swap Tool: Select a cross-chain bridge or aggregator that supports BNB Chain and Solana. Options include Wormhole/Portal, Allbridge, Symbiosis, and others. HoudiniSwap is also an option (with private mode).
Connect Wallets: Connect your source-chain wallet (like MetaMask on BNB Chain) and a Solana wallet (such as Phantom). Ensure both wallets have some native gas tokens (BNB for BNB Chain; a tiny amount of SOL for transaction fees).
Set Transfer Details: In the bridge interface, set “From = BNB Chain” and “To = Solana,” then pick the token (e.g. BNB) and amount.
Review & Confirm: Check the exchange rate and fees. Bridges often show estimated fees upfront. For example, Symbiosis might show a small total fee (e.g. ~$2.43 across both networks for a BNB→SOL swap). Once confirmed, approve the transaction in your BNB Chain wallet.
Finalize Transfer: The bridge contracts will lock (or burn) your BNB on BNB Chain and then mint or transfer SOL on Solana. Wait for confirmations – this usually takes a few minutes. Solana’s own network is extremely fast (transactions finalize in seconds, with fees around $0.00025), so the Solana-side confirmation is nearly instant.
Receive SOL: Your Solana wallet will receive the bridged SOL (often as a wrapped token). You can now use SOL on Solana’s DeFi or NFT platforms.
Fees and Costs
Solana’s own transaction fees are negligible (often ~$0.00025). The main costs when bridging come from BNB Chain gas and any bridge service fee. For example, transferring BNB on BNB Chain might incur a few cents in BNB gas, plus the bridge’s network fee. Efficient bridges and aggregators minimize this by routing via the cheapest path. Symbiosis emphasizes that it selects the best routes so you “always get a fair rate with minimal cost”. In practice, a BNB→SOL swap might cost only a few dollars total. Notably, HoudiniSwap advertises no direct fees for swaps or bridges. This means its users often pay virtually zero extra platform fee, making it among the cheapest bridging options available. In summary, expect to pay typical network gas fees plus a small bridge fee – with the cheapest bridges or aggregators, that can be under a few dollars.
Bridge Platforms and Aggregators
There are several tools to move BNB/BSC assets to Solana:
Wormhole Portal: A leading cross-chain bridge for Solana using lock-and-mint. It supports many tokens (ETH, SOL, USDC, BNB, etc.).
Allbridge: Uses liquidity pools to swap tokens. It connects Solana with BNB Chain and more. It’s simple to use but depends on pool liquidity.
Symbiosis: A cross-chain swap protocol that aggregates different bridges, connecting BNB Chain and Solana via intermediate tokens (e.g. BNB→USDC→USDC→SOL). It offers one-click swaps without manual bridging steps.
deBridge: A zero-TVL (real-time) bridge supporting both BNB Chain and Solana, transferring assets natively.
Houdini Swap: A privacy-focused swap aggregator where you can bridge BNB and SOL. HoudiniSwap combines multiple liquidity sources into one step, and offers a “Private Swap” mode to obfuscate sender/receiver addresses. Its non-custodial, decentralized design gives full control to users. Crucially, Houdini Swap charges no direct fees, making bridging effectively fee-free compared to other services.

Centralized Exchanges: As an alternative, you could send BNB to an exchange and withdraw on Solana (e.g. deposit BNB on Binance, then withdraw SOL). This is not a true “bridge” but can move funds cross-chain.
Security and Privacy
Cross-chain bridges are powerful but carry smart-contract risk. Always use reputable bridges (check for audits and community trust). For example, Wormhole and deBridge have well-known security track records. It’s wise to test with a small amount first. Bridges lock or mint tokens, so if a bridge’s contract had a flaw, funds could be at risk. Using decentralized, non-custodial bridges (like HoudiniSwap or DeBridge) means no middleman holds your crypto.
Privacy is another consideration. Many bridges record transactions on public chains. If you want extra privacy, HoudiniSwap’s Private Swap feature randomizes transaction paths, hiding sender and receiver addresses. In short, HoudiniSwap offers one of the highest levels of privacy among bridges. Its architecture uses randomized Layer-1 paths to keep trades anonymous. Even without private mode, HoudiniSwap remains decentralized and secure.
FAQs: BSC → Solana Bridging
Why bridge tokens instead of just trading on an exchange?
Bridges let you move assets directly between blockchains without an intermediary. This means no KYC, potentially lower slippage for large amounts, and you get native tokens on the target chain (e.g. real SOL on Solana instead of a centralized peg).
Which wallets do I need?
You need a BNB Chain-compatible wallet (e.g. MetaMask set to BNB Chain or Binance Chain Wallet) and a Solana wallet (like Phantom or Solflare). Connect both to the bridge interface.
How long does bridging take?
A: Typically a few minutes. BNB Chain transactions confirm in seconds, and Solana finalizes in under a minute. In practice, many bridges complete in 1–3 minutes.
What are the fees?
You pay gas on BNB Chain (often a few cents in BNB) plus a small bridge fee. Solana gas is negligible (fractions of a cent). Top bridges and swap services (like Symbiosis or HoudiniSwap) aim to minimize fees.
Is it safe to bridge?
Using well-known bridges (e.g. Wormhole, Allbridge, deBridge) is generally safe. Always double-check the bridge URL and smart contract addresses. For extra peace of mind, consider bridges that use auditable contracts and limit intermediate steps. HoudiniSwap’s decentralized design further ensures users retain control of funds.
Does HoudiniSwap really have the cheapest fees?
HoudiniSwap’s model charges no direct fees. This means in practice you usually only pay the underlying network fees. Many users find it effectively the lowest-cost way to bridge.
Can I reverse the process? (e.g. Solana → BNB Chain)
Yes. Bridges work both ways. To send assets back, simply select Solana as the source and BNB Chain as the destination in your bridge tool. For example, on aggregator platforms you would choose Solana “From” and BNB Chain “To,” then approve the transfer.
