User Flow

Optimal User Experience

Our aim is to facilitate cross-chain interactions that are straightforward and efficient for users, providing comprehensive support for all transaction formats and chains. Users are expected to express their transactional intent in a streamlined process: a single authorization should initiate the transaction, while the complex workings of cross-chain transactions remain transparent. For further information, refer to our goals.

1. Intent Submission

Users submits an intent/transaction to Light's Intent Engine with the following information:

• Desired outcome
• Source chain (if applicable)
• Destination chain (if applicable)

Users may also set detailed preferences for the transaction via programmable intents

2. Gas Abstraction

The transaction's gas fees are managed through Light's off-chain gas network, which subsidizes the cost on the target chain(s). Relayers compete to offer the best gas price, ensuring the user's transaction is as cost-effective as possible.

3. Transaction Authorization

Users authorize their transaction with a single signature using Light's cross-chain smart account or via standard External Owned Accounts (EOAs).

4. Programmable Intent Execution

Transactions are then relayed to the target chains, and the user's programmable intent preferences are processed through the Light Layer. Off-chain actors bid to execute these transactions, ensuring the user experiences optimal execution along with enhanced privacy, security, and "programmatic atomicity".

5. Settlement and Confirmation

Finally, transactions are concluded on the target chain(s), and users are promptly informed of the result. As cross-chain transactions are inherently asynchronous, users can follow the progress of their transactions via our custom explorer or other blockchain explorers.
