Account Reconciliation

Account Asset Clearing:

Service providers have two options when requesting asset clearance:

• Synchronous Execution: Verify asset availability, initiate MOB execution, and process further steps upon successful settlement.

• Optimistic Execution: Verify asset availability and process the transaction immediately, assuming successful settlement. This option prioritizes speed but carries risks like double spending or race conditions.

Optimistic Settlement:

MOB leverages background monitoring to track allowances and balances, enabling near-instantaneous responses for feasible operations. However, optimistic settlements are subject to potential risks. MOB provides confirmation upon initiation and processes the claim synchronously. Service providers can choose to wait for transaction finality or a specified time interval.

Supported Asset Clearing Methods:

• Legacy: Users sign transactions on-demand, requiring manual input and lacking transaction guarantees.

• Approval/Allowance: Users grant token allowances to spenders.

• Permit: A signature-based method for ERC20 tokens that eliminates gas fees and offers flexible allowance management.

• Permit2: Similar to Permit, enabling gasless allowance sharing across smart contracts.

• EIP-4337 Account Abstraction: Allows for paymaster-sponsored gasless transactions.

• EIP-3074 (Future): Enables service providers to cover gas costs on behalf of users.
