## 流程

### 1. Acala 公投， proposal batch call
1. mint `110w AUSD` 给 【国库地址】
2. dispatch as 【国库地址】，调用evm call: `aUSD.approve(wormholeBridge合约地址, 110w)`
3. dispatch as 【国库地址】，调用 evm call:`wormholeBridge.tokenTransfer(karura-chain, 110w, honzon-bridge系统账户HonzonBridgeAccount 对应的 evm 地址)`

batch call:
`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`

### 2. Karura 公投
1. mint `45w KUSD` 给 `honzon-bridge系统账户HonzonBridgeAccount`

call:
`0x0c02006d6f646c6163612f687a6267000000000000000000000000000000000000000000810000eda49db83e060000000000000000`

### 3. 执行 karura 上wormholeBridge合约的completeTransfer
Redeem: dispatch as ??? , 调用karura 上 wormholeBridge合约的completeTransfer(可以用wormhole-relayer完成redeem)

### 4. council 开启开关
设置wormhole的`waUSD erc20 地址`（honzonBridge.setBridgedStableCoinAddress) // 启用开关，确保这一步是最后执行的

## 结果
`honzon-bridge系统账户HonzonBridgeAccount` 持有 45w KUSD 和 110w waUSD
