What is Bridge, Transfer, Bridge & Execute?

In Nexus, apart from crosschain swaps, users can do Bridge, Transfer, Bridge & Execute which uses Nexus chain abstraction (aka Bridge Methods).

Let’s understand what each Nexus operation is and what it does.

Bridge

During the Bridge operation, the funds are bridged from N source chains to the user’s preferred destination chain.

Sender = Recipient

This function uses the BridgeParams struct and the bridge function from the Bridge Methods in the SDK.

Transfer

During the Transfer operation, the funds are bridged from N source chains from the Sender to the user’s preferred destination chain at a different Receiver address. It is a compound operation i.e. it involves the bridging of funds from different sources to a destination chain and then funds are transferred to the Recipient address.

Sender != Recipient

This function uses the TransferParams struct and the bridgeAndTransfer function from the Bridge Methods in the SDK.

Bridge & Execute

The Bridge & Execute operation is a more complex compound operation in Nexus. In this operation, the user bridges liquidity from N sources chains if there is a lack of enough liquidity on the destination chain, and then executes any arbitrary smart contract function.

Note that the smart contract can be any onchain contract on the destination chain. ALl the developer needs is the contract address, function name & params, and ABI.

For users, this means they don’t have to do a separate bridge action to use a Liquid App (Nexus powered application), and just use the app as they would if they had liquidity onchain.

A bridgeless experience.

This function uses the BridgeAndExecuteParams struct and the bridgeAndExecute function from the Bridge Methods in the SDK.
