gm gardeners!

The Garden just got a little more radiant. We're thrilled to announce support for Solana, marking our first venture into the SVM ecosystem. While we've been cultivating Bitcoin bridges across L2s and EVM chains, this Solana integration opens entirely new soil for us to explore.

Summary: How to Bridge Bitcoin to Solana blockchain

This concise summary outlines the step-by-step process for bridging Bitcoin to Solana using Garden Finance. The Bitcoin to Solana atomic swap allows users to move assets securely and efficiently between the two networks.

1. Connect your Bitcoin and Solana wallet.
2. Select BTC as the send asset and SOL on Solana as the receive asset, then enter the amount of BTC you want to swap for SOL.
3. You will see the swap details, including the fee, after checking. Confirm the transaction by clicking swap.
4. Once initiated, you will receive SOL in your connected Solana wallet, you can monitor transaction status & details on the Garden Explorer. 

Introduction to Solana Ecosystem

Solana Overview

Solana has quickly become a powerhouse in the world of blockchain networks, offering a robust and decentralized platform for a wide range of applications. As a high-performance blockchain, the Solana ecosystem supports everything from decentralized finance (Defi) and NFTs to payments and gaming, all within a single, global state machine. Since its launch in 2020, Solana has attracted a vibrant community of users and developers, building an ever-expanding network of tokens, assets, and applications.

What is a Solana Bridge?

Solana bridges play a crucial role in enhancing the interoperability, liquidity, and overall utility of the Solana network by facilitating secure and seamless asset transfers between Solana and various blockchain networks. These bridges operate by locking assets on the source blockchain and minting equivalent assets on Solana through smart contracts, namely the lock-and-mint model, which is a common method used by bridges to facilitate asset transfers. However, Garden Finance employs a different approach based on trustless atomic swaps using Hashed Timelock Contracts (HTLCs), which ensures that assets never leave the user's control during the bridging process. This unique method is explained in detail later in the article.

The Value

For Bitcoin holders looking to access opportunities on Solana, the path has traditionally meant navigating centralized exchanges or multi-step bridging processes. Garden changes that, enabling direct Bitcoin to Solana swaps in seconds; connecting Bitcoin's trillion-dollar network to Solana's high-speed ecosystem without the friction.

Now you can bridge native Bitcoin directly to Solana and back in just 30 seconds, or swap from any of our supported assets across Bitcoin, Ethereum, Arbitrum, Base, Starknet, HyperEVM, BNB Chain, and more straight into Solana. Garden's trustless architecture ensures your assets never leave your control during the bridging process.

Garden Finance currently supports these assets on Solana: 

• SOL
• CASH
• USDC 
• cbBTC  

While we've built Bitcoin bridges across Bitcoin L2s and EVM chains, supporting Solana's unique architecture unlocks the door for integrating many other non-EVM chains in the future. Think of it as planting seeds for a much larger, more diverse garden.

Solana Wallets

To interact with the Solana network and take full advantage of its ecosystem, you'll need a Solana wallet. A Solana wallet is a secure digital wallet designed to store, send, and receive SOL and other Solana-based SPL tokens.

Garden Finance supports the following wallets on Solana:

• Phantom
• MetaMask
• Solflare
• Backpack
• OKX Wallet

The process is straightforward: connect your Solana wallet to Garden, select your source blockchain, and choose the Solana network as your destination. With just a click, you're ready to securely move assets and explore everything Solana has to offer.

With your wallet ready, let’s dive into the security and trustless features that make Garden’s bitcoin to solana bridge unique.

Ready to experience Solana through Garden? Head over to app.garden.finance and select Solana as your destination chain. From Bitcoin to Solana in seconds, it's that simple.

Garden is the fastest Bitcoin bridge, enabling cross-chain Bitcoin swaps in as little as 30 seconds. It is built using an intents-based architecture with trustless settlements, ensuring zero custody risk for users. 

Security and Routing

Trustless Atomic Swaps with HTLCs

Garden's Bitcoin to Solana bridge is built on trustless atomic swaps using Hashed Timelock Contracts (HTLCs). HTLCs are smart contracts that enable atomic cross-chain swaps between Bitcoin and Solana. HTLCs ensure that either both sides of the swap complete successfully, or the transaction is reverted, so your funds are never at risk of being stuck or lost. Our contracts are continuously audited by external security researchers including Trail of Bits, Zellic, and Ottersec. Full audit history is tracked at garden.finance/security.

This architecture means your Bitcoin never leaves your control during the bridging process. There are no intermediaries, no custody handoffs, and no trust assumptions required.

The swap either completes fully on both chains, or it reverts entirely. No partial execution, no stuck funds. This atomic settlement guarantee is enforced cryptographically, not by validators or multisigs that could be compromised.

When using Garden, verify you're on the legitimate site (app.garden.finance). All transaction fees are displayed upfront before you confirm; no hidden costs. The swap quotes you see are the rates you get.

Not all bridges work this way. Many rely on wrapped tokens, validator sets, or custodial infrastructure that introduce trust assumptions and attack vectors. Garden eliminates those dependencies. Your Bitcoin moves from one chain to another through direct cryptographic proofs, not through systems you have to trust.

Optimal Routing

Garden Finance takes the guesswork out of cross-chain swaps by using an advanced network of solvers to find the most efficient execution path for every transaction. By tapping into multiple liquidity sources, Garden ensures you get the best possible swap rates when moving BTC to Solana or any other supported asset. 

This optimal routing not only maximizes liquidity and minimizes costs. Whether you’re accessing decentralized exchanges, lending platforms, or other Defi protocols, Garden’s network provides a secure, trustless, and seamless swap experience. It’s all about giving users the freedom to move assets across chains and tap into the full potential of the decentralized ecosystem.

What's Next

This is just the beginning of our Solana journey. We’re already working on SPL20 support, which will unlock support for more tokens on Solana in the coming weeks. 

When using a bridge to Solana, users should consider several key factors, including security, custody model, transaction fees, and slippage. Maintaining security and non-custodial execution during the bridging process is essential, especially for decentralized exchanges.

Frequently Asked Questions

Does Garden Finance support cross-chain swaps to Solana?

Yes. Garden supports direct swaps from native Bitcoin, Ethereum, Arbitrum, Base, Starknet, HyperEVM, BNB Chain, and other supported chains to Solana. You can swap assets like BTC, WBTC, cbBTC, USDC, and more directly to Solana assets in seconds using trustless atomic swaps.

How do I convert BTC to SOL?

You can convert BTC to SOL using a bridge or a centralized exchange service. Platforms like Garden allow you to swap BTC for SOL with low transaction fees without giving up custody and at the current market rate, making the process fast and straightforward.

Can I swap SOL back to Bitcoin or other chains?

Yes. Garden supports bidirectional swaps. You can bridge SOL from Solana back to native Bitcoin (typically in 30 seconds) or swap to assets on any other Garden-supported blockchains using the same trustless process.
