+## Reference Implementation
 
 For reference implementation can be found [here](../assets/erc-7818/README.md), But in the reference implementation, we employ a sorted list to automatically select the token that nearest expires first with a First-In-First-Out (`FIFO`) and sliding window algorithm that operates based on the `block.number` as opposed to relying on `block.timestamp`, which has been criticized for its lack of security and resilience, particularly given the increasing usage of Layer 2 (L2) networks over Layer 1 (L1) networks. Many L2 networks exhibit centralization and instability, which directly impacts asset integrity, rendering them potentially unusable during periods of network halting, as they are still reliant on the timestamp.
