Building on the AggLayer comes with enormous benefits, with developers gaining the ability to create superior user experiences through bridgeAndCall() capabilities.
Understanding bridgeAndCall()
Smart contracts in the AggLayer utilize bridgeAndCall() to enable streamlined composability and interoperability across sovereign chains. This functionality abstracts the complexities of multichain ecosystems, allowing users to interact seamlessly without needing to know which chain they're on.
Key Advantages:
- Simplified UX: Eliminates cumbersome bridging processes.
- Cross-chain efficiency: Enables single-click cross-chain applications.
- Future-proofing: Transactions will become faster and cheaper as the AggLayer evolves.
Developers can leverage bridgeAndCall() to create web-like experiences while maintaining security through pessimistic zero-knowledge proofs.

How bridgeAndCall() Works
Core Functionality
bridgeAndCall() combines two critical operations:
- Bridging assets between chains.
- Triggering smart contracts on the destination chain.
This combination allows developers to program complex, multi-chain workflows that execute in a single transaction.
Example Use Case
A user could:
- Transfer an asset from Chain A to Chain B
- Execute a swap
- Transfer the new asset to a gaming chain
- Mint an NFT
All through one click via bridgeAndCall().
Technical Deep Dive
Security Foundations
The AggLayer's unified bridge is protected by:

Transaction Flow:
- Asset bridging to destination chain
- Message bridging with control fields
- AggLayer processing
- Asset claiming
- Message execution via JumpPoint
- Contract execution and cleanup
Future Potential
As more chains join the AggLayer, bridgeAndCall() will enable:
- Truly specialized appchains
- Seamless cross-chain composability
- New decentralized application paradigms
