Developers can create advanced DeFi applications—like cross-chain DEXs, yield aggregators, and lending platforms—without being limited by blockchain compatibility Overview | Synapse Protocol

Developer-Friendly Tools

Step 1: Connect Your Wallet

Begin by navigating to the official Synapse Bridge. Connect a supported cryptocurrency wallet such as MetaMask. This connection serves as your interface for managing asset transfers across different blockchain networks.

Step 2: Select Source and Destination Blockchains

Once your wallet is connected, select the blockchain network where your assets are currently stored (source chain) and choose the target blockchain (destination chain). For instance, if you hold assets on Ethereum but want to transfer them to Avalanche, select Ethereum as the source and Avalanche as the destination.

Step 3: Choose Asset and Transfer Type

Synapse Bridge offers two main types of transfers: Canonical Token Bridging: This method involves transferring wrapped assets between blockchain networks. Liquidity-Based Bridging: For this type, the bridge utilizes liquidity pools to swap native assets, offering efficient and fast cross-chain swaps Overview | Synapse Protocol

Step 4: Confirm and Complete the Transfer

After choosing the type of asset and amount to transfer, review the provided quote for fees, slippage, and estimated time of completion. The RFQ relayers in Synapse help ensure that users get competitive rates. Confirm the transaction via your wallet, and you can track its progress through the bridge interface Overview | Synapse Protocol

Step 5: Track and Manage Your Assets

After initiating the transaction, you can track the asset transfer’s status in real-time. Upon successful confirmation on both the source and destination blockchains, your assets will appear on the target network.

Battled-test infrastructure

Synapse has processed millions of transactions and tens of billions in bridged assets.
