安装在 Forge 链节点上的合约是支持开发者在必要的情况下可以临时禁用或者启用的，比如在发现合约漏洞之后立即停用，可以降低损失。

执行 forge contract:ls 可以查看所有已经安装的合约列表。

禁用某个合约
可以根据合约的名称或者 DID 去启用合约，如果合约处于禁用状态是不能执行禁用操作的，处于禁用状态的合约在通过 SDK 发送对应的 Transaction 的时候会收到 unsupported_tx 的错误。
执行 forge contract:deactivate transfer：
ℹ Working on app-chain chain
ℹ Connect to grpc endpoint: tcp://127.0.0.1:28210
✔ Moderator checked success
✔ Contract z2E437q48tJcTQ8n7NxXDdEWt5odcjjCePSBh successfully deactivated

然后查看发送的 Transaction：
forge tx 59D4B33D8F9ACAED0954AE5C90A15FA2170377AF4B6F41867193F1B2DCC3FA80
得到如下的结果：

再次验证合约状态，forge contract:ls | grep transfer，处于 paused 状态：
│ transfer │ z2E437q48tJcTQ8n7NxXDdEWt5odcjjCePSBh │ paused │ v3 │
启用某个合约
可以根据合约的名称或者 DID 去启用合约，如果合约处于运行状态是不能执行启用操作的，只有处于启用状态（running）的合约才能通过 SDK 发送对应的 Transaction。
执行 forge contract:activate transfer 可以把刚才禁用的转账合约重新激活：
❯ forge contract:activate transfer
