Bitcoin Bridge (by Garden Finance)
What is GardenFinance?
GardenFinance is a Bitcoin Bridge integration powered by Gardenfi that allows users to seamlessly transfer BTC-based assets between supported blockchains and Bitcoin. This function enables automated, secure cross-chain transfers directly within your K3 Labs workflows, eliminating the need for complex manual bridging processes.
With GardenFinance, you can automate Bitcoin transfers as part of larger workflows, such as moving funds based on market conditions, portfolio rebalancing, or executing conditional transfers triggered by smart contract events.
Supported Chains
GardenFinance supports transfers between the following blockchains:
EVM-Compatible Chains:
Ethereum Mainnet
Base Mainnet
Ethereum Sepolia Testnet
Base Sepolia Testnet
Arbitrum Mainnet
Bitcoin Networks:
Bitcoin Mainnet
Bitcoin Testnet
Transfer Directions:
EVM → Bitcoin: Transfer BTC-based tokens from EVM chains to Bitcoin
Bitcoin → EVM: Transfer Bitcoin to supported EVM chains (functionality may vary)
Note: Transfers from chains not listed above are not currently supported. Both mainnet and testnet environments are available for testing and production use.
Supported Tokens
GardenFinance currently supports the following BTC-based tokens:
cbBTC (Coinbase Wrapped Bitcoin)
wBTC (Wrapped Bitcoin)
iBTC (Interlay Bitcoin)
BTC (Native Bitcoin)
How It Works
Step 1: Configure Source and Destination
Source Chain: Select one of the supported EVM chains or Bitcoin where your assets currently reside
Destination Chain: Choose your target blockchain (Bitcoin mainnet/testnet or supported EVM chain)
Token Selection: Pick the BTC-based token you want to transfer
Step 2: Set Transfer Amount
Minimum Transfer: Ensure your transfer amount meets the minimum requirement of 0.0005 BTC
Amount Validation: The function will automatically validate that your transfer amount meets all requirements
Step 3: Prepare Your Wallet
Before initiating the transfer, ensure your Cubist wallet has sufficient funds: Your Cubist wallet must contain enough native tokens (ETH, AVAX, etc.) to cover transaction fees on the source chain
Important: Insufficient gas in your Cubist wallet will cause the transfer to fail. Always check your gas balance before proceeding.
Step 4: Initiate the Transfer
Once configured and wallet is prepared, the GardenFinance function will:
Lock Tokens: Secure your tokens in a smart contract on the source chain
Cross-Chain Processing: Automatically manage the cross-chain transfer through Gardenfi's infrastructure
Token Release: Release the equivalent assets on the destination chain to your specified recipient address
Step 5: Confirmation and Completion
Transfer Time: Most transfers complete within 5-10 minutes
Network Conditions: Actual completion time may vary based on network congestion
Transaction Tracking: Monitor transfer progress through the workflow execution logs
Key Requirements
Wallet Type: Cubist wallet integration required
Minimum Amount: 0.0005 BTC minimum transfer
Gas Requirements: Sufficient native tokens for transaction fees
Supported Networks: Limited to listed EVM chains and Bitcoin networks
Transfer Direction: Both EVM-to-Bitcoin and Bitcoin-to-EVM supported
Troubleshooting
Common Issues and Solutions:
Insufficient Gas Error
Ensure your Cubist wallet has enough native tokens (ETH, AVAX, etc.) for transaction fees
Check gas prices and add buffer for network congestion
Transfer Below Minimum
Ensure transfer amount is at least 0.0005 BTC
Account for any fees that might reduce the final transfer amount
Extended Transfer Times
Normal completion time is within 10 minutes
If transfer takes longer than 15 minutes, check network status
