- Replaced enshrined tokens with contracted tokens, introducing the `TokenManager` to manage token balances within each shard. - `TokenManager` is deployed on each shard and holds the balances for all tokens within that shard. - Introduced a new `Relayer` contract to handle Cross-Shard Transactions (CST). The `Relayer`: - Calls the `TokenManager` before and after CSTs to ensure token transfers and consistency. - Handles bounce, response, and request transactions. Key Issues with the new approach: - Increased costs: CSTs and token manipulations are now more expensive. - Token removal inefficiency: Tokens are not removed from accounts if the balance becomes zero due to high costs. - Limited nested request support: Nested requests (sending a request from a response handler) are not supported. - Compilation issues: Previous contract compilation settings caused a "too deep stack" error. Resolved by using `via-ir` and `optimize` options for all contract compilations. - Test issues: Some tests were disabled due to incomplete support for gas forwarding and bounce messages.
