Deposit and Vault Entry

1. Deposit and Vault Entry

Cross-Chain Deposit Into User’s SmartAccount

The user begins by interacting with the cross-chain aggregator ( Stargate, LiFi) to route assets from the source chain to the destination chain. Once bridging is completed, the assets are delivered directly into the user's SmartAccount (EIP-4337), which serves as the non-custodial settlement endpoint.

SmartAccount Settlement

The SmartAccount interacts with the Teller to initiate the vault deposit. All SmartAccount operations are gas-sponsored by the Prime Paymaster, allowing users to deposit without paying gas.

Mint share

The Teller requests the Accountant to calculate the number of Vault Shares representing the user’s Principal, then submits a mint request to the StakingVault, which issues the shares to the user’s smart account.
