## Proposal objective

Keep tier limits in sync between Optimism and Polygon, i.e. add KYB-tier limits on BOB & ETH. pools on Optimism.

## Proposal Details

The following changes in limits will be applied to zkBob BOB pool on Optimism:

| Tier                              | Single deposit  | Daily user deposit | Daily deposit   | Daily withdrawal | Pool size          | Single DD     | Daily user DD  |
| --------------------------------- | --------------- | ------------------ | --------------- | ---------------- | ------------------ | ------------- | -------------- |
| Tier 1 (default, id 0)            | 10,000 BOB      | 10,000 BOB         | 300,000 BOB     | 300,000 BOB      | 10,000,000 BOB     | 1,000 BOB     | 10,000 BOB     |
| Tier 2 (KYC NFT, id 254)          | 20,000 BOB      | 20,000 BOB         | 300,000 BOB     | 300,000 BOB      | 10,000,000 BOB     | 1,000 BOB     | 10,000 BOB     |
| Tier 3 **(new)** (Partners, id 1) | **100,000 BOB** | **100,000 BOB**    | **300,000 BOB** | **300,000 BOB**  | **10,000,000 BOB** | **1,000 BOB** | **10,000 BOB** |

The following changes in limits will be applied to zkBob ETH pool on Optimism:

| Tier                              | Single deposit | Daily user deposit | Daily deposit | Daily withdrawal | Pool size    | Single DD  | Daily user DD |
| --------------------------------- | -------------- | ------------------ | ------------- | ---------------- | ------------ | ---------- | ------------- |
| Tier 1 (default, id 0)            | 5 ETH          | 5 ETH              | 150 ETH       | 150 ETH          | 1000 ETH     | 5 ETH      | 5 ETH         |
| Tier 2 (KYC NFT, id 254)          | 10 ETH         | 10 ETH             | 150 ETH       | 150 ETH          | 1000 ETH     | 10 ETH     | 10 ETH        |
| Tier 3 **(new)** (Partners, id 1) | **50 ETH**     | **50 ETH**         | **150 ETH**   | **150 ETH**      | **1000 ETH** | **50 ETH** | **50 ETH**    |

## Proposal breakdown

#### Optimism

The transaction [#11](https://app.safe.global/transactions/tx?safe=oeth:0x14fc6a1a996A2EB889cF86e5c8cD17323bC85290\&id=multisig_0x14fc6a1a996A2EB889cF86e5c8cD17323bC85290_0x21fb268294b38cd69760b492c44fe81c85b48a0164f29959f8ff21476f7dea5d) in the Safe on Optimism contains 4 actions:

**Action 1**

Set Optimism BOB limits for tier id `1`

**Action 2**

Add `0x6a3154a1f55a8faf96dfde75d25eff0c06eb6784` to tier `1` in Optimism BOB pool as the first partner.

**Action 3**

Set Optimism ETH limits for tier id `1`

**Action 4**

Add `0x6a3154a1f55a8faf96dfde75d25eff0c06eb6784` to tier `1` in Optimism ETH pool as the first partner.

### Additional verification

1. Inspection of [`0x6a3154a1f55a8faf96dfde75d25eff0c06eb6784`](https://polygonscan.com/address/0x6a3154a1f55a8faf96dfde75d25eff0c06eb6784#tokentxns) address demonstrates that this account already has extended limits for the zkBOB USDC pool.
2. Check transaction logs in Tenderly simulation.
