57-71: LGTM! The changes enhance the handling of the recovery ID in Ethereum signatures.The code segment correctly identifies the byte position of the recovery ID within the signature and normalizes it to either 0 or 1, which is the expected format for the
crypto.SigToPubfunction. The normalization process accounts for common values of 27, 28, 0, and 1, improving the robustness of the signature verification process.Additionally, the error handling for unexpected recovery ID values, along with the appropriate JSON response and status code, enhances the overall functionality of the authentication process.

| The implementation for certain native bridges (e.g Scroll) is also supported. It works slightly differently as flows are only supported between Scroll and Mainnet. At a high level, the rebalancer checks inventory on Scroll versus other chains, and if imbalanced, initiates a bridge to mainnet, allowing the CCTP relayer to rebalance funds where needed. | ||

Clarify implementation details for native bridges.
The section on native bridges, such as Scroll, mentions different operational flows. It would be beneficial to provide more specific examples or a deeper explanation of how these flows differ from the standard operations. Also, correct the abbreviation "e.g." to "e.g.," and consider adding a comma after "differently" for better readability.

| Automated rebalancing is configurable by token and currently supports CCTP routes as well as native bridging in the case of Scroll. Rebalancing evaluation follows this logic on every `rebalance_interval`: | ||
|
|
||
| - For every supported rebalance method, compute the 'total balance' of each token as the sum of all balances across chains that support the given rebalance method. | ||
| - For every supported token, compute the 'maintenance threshold' as the product of the `maintenance_balance_pct` and the 'total balance'. A token is eligible for rebalancing if the current balance is below the 'maintenance threshold'. | ||
|
|
||
| To limit the amount of inventory that is inflight, only one rebalance can be pending at a time for each token. As such, we select the 'best' rebalance candidate as the rebalance with the largest delta between origin balance and destination balance. | ||

| The final step in evaluating a rebalance is determining the rebalance amount: | ||
|
|

| - Arrive at an initial rebalance amount by computing the delta between current balance and the initial threshold on origin. | ||
| - Check if this rebalance amount is too much, i.e. it would take the destination balance above its initial threshold. If so, clip the rebalance amount to target the destination initial threshold. | ||

| We are dealing with chains 1, 2, and 3. Chains 1 and 2 support USDC with CCTP, and chain 3 supports USDC but does not support CCTP. Each chain has a `maintenance_pct` of 20%, while chains 1 and 2 have `initial_pct` of 40% and chain 3 has 20%. Assume chain 1 has a balance of 100 USDC, chain 2 has 900 USDC, and chain 3 has 2000 USDC. | ||
|
|
||
| The system would trigger a rebalance from chain 2 to chain 1, since the total balance of CCTP-supported chains is 1000 USDC, and chain 1 is below the 20% maintenance threshold. Chain 3 is not considered for rebalance since it does not support CCTP. | ||
|
|
||
| The rebalance amount would be initially be targeted as 600 since this would take chain 2 to its 40% initial threshold. However, since chain 1 only needs 300 to reach its initial 40% threshold, the rebalance amount is clipped at 300. | ||
|
|
||
| So, the final result is a rebalance of 300 USDC from chain 2 to chain 1, leading to chain 1 having 400 USDC, chain 2 having 600 USDC, and chain 3 having 2000 USDC. | ||

Detailed review of the rebalancing process.
The expanded explanation of the rebalancing process is clear and detailed, especially with the inclusion of an illustrative example. This should greatly aid users in understanding how rebalancing works across multiple chains. However, consider addressing the following:
- Line 49 has a grammatical error with the phrase "would be initially be targeted." It should be corrected to "would initially be targeted."
- Ensure that all technical terms used in the example are defined somewhere in the document or linked to a glossary for clarity.
- The rebalance amount would be initially be targeted as 600 since this would take chain 2 to its 40% initial threshold.
+ The rebalance amount would initially be targeted as 600 since this would take chain 2 to its 40% initial threshold.Committable suggestion

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
| Automated rebalancing is configurable by token and currently supports CCTP routes as well as native bridging in the case of Scroll. Rebalancing evaluation follows this logic on every `rebalance_interval`: | |
| - For every supported rebalance method, compute the 'total balance' of each token as the sum of all balances across chains that support the given rebalance method. | |
| - For every supported token, compute the 'maintenance threshold' as the product of the `maintenance_balance_pct` and the 'total balance'. A token is eligible for rebalancing if the current balance is below the 'maintenance threshold'. | |
| To limit the amount of inventory that is inflight, only one rebalance can be pending at a time for each token. As such, we select the 'best' rebalance candidate as the rebalance with the largest delta between origin balance and destination balance. | |
