Synapse Bridge

Synapse Bridge is a multichain bridge that enables on-chain asset swaps between Canto and 10+ other blockchains, including Ethereum, Polygon, Optimism, Arbitrum, Avalanche, BNB Chain, and others.

Using Synapse Bridge

The Synapse bridging process is identical regardless of whether you are bridging to or from Canto. To use the bridge, follow these steps:

1. Navigate to https://synapseprotocol.com/ and connect your wallet.

2. Under the Origin section, select the network you would like to bridge from, as well as the asset you would like to send and its amount.

3. Under the Dest. section, select the network you would like to bridge to (e.g. Canto) and the asset you would like to receive.

4. If necessary, click the Approve button and confirm the transaction in your wallet to approve the outgoing asset.

5. Finally, click the Bridge your funds button and confirm the transaction in your wallet to initiate the bridging process:

Supported Assets

The Synapse Bridge supports the following assets on Canto:

• USDC

• USDT

• NOTE

• nUSD

• SYN

Swap Routing

To ensure deep liquidity when bridging to and from Canto, the Synapse Bridge performs direct cross-chain swaps for just two assets:

• nUSD – Synapse's stablecoin bridge asset
• SYN – Synapse's governance and incentive token

To send and receive other stablecoins on Canto, the Synapse Bridge swaps to and from nUSD using chain-specific stableswap pools on the origin and destination chains.

Synapse's Canto Stableswap Pool consists of nUSD and NOTE, enabling users to bridge stablecoins across chains and swap to and from Canto's native unit of account in a single interaction.

Additionally, the Synapse Bridge integrates the Canto DEX for its feeless USDC <> NOTE and USDT <> NOTE liquidity. This means that users can bridge to and from USDC and USDT on Canto in a single interaction, via nUSD and NOTE.
