# 部署通用合约 (Deploy a generic contract)

If you have your own chain running already ([see instruction here](https://docs.seinetwork.io/smart-contracts-and-local-development/set-up-a-local-network)), the following steps show how to upload your contract to that chain. Sei is a permissioned network, which means that only wasm contracts which are voted on by governance can be deployed to the chain.

如果您已经有自己的链在运行（[参见此处的说明](https://docs.seinetwork.io/smart-contracts-and-local-development/set-up-a-local-network)），请执行以下展示如何将您合约上传到该链步骤。 Sei 是一个许可网络，这意味着只有经过治理投票的 wasm 合约才能部署到链上。

### 1.构建 Cosmwasm 合约 (1.Build Cosmwasm contract)

Build the image. Note that the following steps are run from your contract directory, so they assume seid is in your $PATH:

构建图像。请注意，以下步骤是从您的合约目录运行的，因此它们假定 seid 在您的 $PATH 中：

```
cargo build
```

```
docker run --rm -v "$(pwd)":/code --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry cosmwasm/rust-optimizer:0.12.5
```

### 2.上传合约的治理提案 (2.Governance Proposal to Upload a Contract)

**Note that on local sei you can skip steps 2 and 3, and directly store the wasm contract like the following:**

**请注意，在本地 sei 上，您可以跳过第 2 步和第 3 步，直接存储 wasm 合约，如下所示：**

```
seid tx wasm store $CONTRACT_WASM_BINARY -y --from=$ACCOUNT_NAME --chain-id=$CHAIN_ID --gas=10000000 --fees=10000000usei --broadcast-mode=block
```

Go back to **sei-chain repo**, and submit a governance proposal to upload the wasm contract.

返回 **sei-chain repo**，并提交治理提案以上传 wasm 合约。

```
seid tx gov submit-proposal wasm-store artifacts/$CONTRACTNAME.wasm \

--from $(seid keys show -a $ACCOUNT_NAME) \

--run-as $(seid keys show -a $ACCOUNT_NAME) \

--title "<Enter title proposal title for uploading of wasm contract>" \

--description "<Enter description of proposal and contract>" \

--chain-id sei-chain \

--instantiate-everybody "false" \

--instantiate-only-address $(seid keys show -a $ACCOUNT_NAME) \

--broadcast-mode=block \

--gas=500000 \

--fees=10000000usei
```

Reference <https://docs.cosmwasm.com/tutorials/governance/#submit-proposal> for more details on each of the flags and details about contract instantiation/execution.

参考 <https://docs.cosmwasm.com/tutorials/governance/#submit-proposal> 了解有关每个标志和有关合约实例化/执行的详细信息。

### 3.对治理提案进行投票 (3.Voting on the Governance Proposal)

Once the governance proposal has been submitted, it must be approved by governance. Find the proposal id and vote on it

治理提案一经提交，必须得到治理层的批准。找到提案 id 并对其进行投票

```
seid tx gov vote [proposal-id] yes --from $ACCOUNT_NAME
```

### 4.实例化合约 (4.Instantiating contract)

Once your proposal is approved, you can instantiate your contract.

一旦您的提案获得批准，您就可以实例化您的合约。

Note in this example the $CONTRACT\_ID is 1 and $LABEL is any contract name you want:

注意在这个例子中 $CONTRACT\_ID 是 1 并且 $LABEL 是你想要的任何合约名称：

```
seid tx wasm instantiate $CONTRACT_ID '{}' --chain-id sei-chain --from $ACCOUNT_NAME --gas=4000000 --fees=1000000usei --broadcast-mode=block --label $LABEL --no-admin
```

Note that the `'{}'` part is the parameters you pass to instantiate the contract. In this example, the contract takes no parameter so `'{}'` suffices. For any real world contracts, their instantiation parameters would likely be non-empty. For example, to instantiate Vortex contract, the following parameters need to be used instead (the actual values need/can be changed though):

请注意，`'{}'` 部分是您传递的实例化合约的参数。在这个例子中，合约没有参数，所以 ''{}'' 就足够了。对于任何现实世界的合约，它们的实例化参数都可能是非空的。例如，要实例化 Vortex 合约，需要使用以下参数（但实际值需要/可以更改）：

```
{"whitelist": ["sei1h9yjz89tl0dl6zu65dpxcqnxfhq60wxx8s5kag"],"use_whitelist":false,"admin":"sei1h9yjz89tl0dl6zu65dpxcqnxfhq60wxx8s5kag","limit_order_fee":{"decimal":"0.0001","negative":false},"market_order_fee":{"decimal":"0.0001","negative":false},"liquidation_order_fee":{"decimal":"0.0001","negative":false}}
```

You should get a response like the following:

您应该得到如下响应：

```
height: "2051"

info: ""

logs:

```

From the output, you can see that your contract was created at address: `sei1wug8sewp6cedgkmrmvhl3lf3tulagm9hnvy8p0rppz9yjw0g4wtqdxfzff`. You will need this address for any contract interaction.

从输出中，你可以看到你的合约是在下面地址创建的：`sei1wug8sewp6cedgkmrmvhl3lf3tulagm9hnvy8p0rppz9yjw0g4wtqdxfzff`。您将需要在此地址进行任何合约交互。

### 5.执行合约 (5.Execute contract)

In this example, we send a `UpdatePrice` message to update the `price` of a token on this oracle contract.

在此示例中，我们发送一条“UpdatePrice”消息来更新此预言机合约上代币的“价格”。

```
{

"update_price": {

"price": "22",

"token_addr": "cosmos16fz9ma2thw3vycca0v9qkezgecusgzza8027z4"

  }

}
```

```
seid tx wasm execute $CONTRACT_ADDR '{"update_price": {"price": "22", "token_addr": "$TOKEN_ADDR"}}' --from $ACCOUNT_NAME --gas=4000000 --fees=1000000usei --chain-id sei-chain --broadcast-mode block
```

### 6.查询合约 (6.Query contract)

In this example, we send a `GetPrice` message to get the `price` of a token on this oracle contract.

在这个例子中，我们发送一个“GetPrice”消息来获取这个预言机合约上一个代币的“价格”。

```
{

"get_price15": {

"token_addr": "cosmos16fz9ma2thw3vycca0v9qkezgecusgzza8027z4"

}

}

seid query wasm contract-state smart $CONTRACT_ADDR '{"get_price15": {"token_addr": "#TOKEN_ADDR"}}'
```
