Send has introduced the Base-to-Canton Bridge, allowing selected assets from Base to move directly into Send App on Canton.
The first supported assets are SEND, USDC, cbBTC, and frxUSD. Once bridged, each asset appears on Canton as a wrapped version using a temporary .B suffix: SEND.B, USDC.B, cbBTC.B, and frxUSD.B.
The bridge gives Base users a direct way to bring existing balances into Send Canton Wallet, where sending, receiving, and swaps are already live.
A retail path into Canton
Canton was built first for institutions. Send’s focus has been to make that infrastructure usable for everyday users.
That work already includes Send Canton Wallet, a dedicated Canton experience with its own wallet, transfers between Canton users, and swaps across CC, CUSD, and USDCx.
The Base-to-Canton Bridge builds on that foundation by letting users move selected Base balances into their Canton wallet inside Send App.
How the bridge works
The bridge uses a lock-and-mint model.
When a user bridges an asset from Base, the asset is locked on Base. A wrapped version is then minted on Canton and delivered to the user’s Canton wallet inside Send App on Canton.
The first supported mappings are:
SEND → SEND.B
USDC → USDC.B
cbBTC → cbBTC.B
frxUSD → frxUSD.B
Once the wrapped asset is in Send Canton Wallet, users can hold it, send it to another Canton wallet, or keep it as a Canton-side position while more bridged assets and liquidity pools are added.
Send plans to add more assets in later phases of the rollout.
Why the launch starts with four assets
Send is beginning with four assets rather than opening the bridge to every Base asset at launch.
The narrower rollout makes the launch easier to support and review. It also avoids minting a wide set of wrapped tokens on Canton before pools, trading pairs, or clear use cases exist for them.
Each asset in the first set has a specific role.
SEND is the Send token, making it the natural starting point for Send’s Base-to-Canton path.
USDC brings a widely used Base dollar asset into Canton.
cbBTC brings Coinbase Wrapped BTC from Base into Send Canton Wallet.
frxUSD adds Frax’s stablecoin to the first supported set, giving the launch both a major dollar asset and a DeFi-native stablecoin.
Together, the first four assets give Canton a focused starting point for Base-originated retail liquidity.
What it means for users
Users who already hold SEND, USDC, cbBTC, or frxUSD on Base now have a path to bridge those balances into Send App on Canton.
For existing Send Canton Wallet users, the bridge brings more retail assets into the app they already use. As more assets move across, the supply of SEND.B, USDC.B, cbBTC.B, and frxUSD.B on Canton can grow.
Send plans to add liquidity pools for supported pairs after enough supply has bridged across and trading demand develops.
Controlled rollout
The Base-to-Canton Bridge is beginning with a controlled release.
Full functionality is planned to become available to all users over the next 24 hours as the system expands beyond the initial deployment window.
Users who do not yet have a Send Canton Wallet account or invite can get Send App, complete Send Verified, and receive an instant invite link to Send Canton Wallet.
The bridge gives Base users a clear first step into Send Canton Wallet and gives Canton users a more direct route for retail assets to arrive through Send.
