Creating a Paymaster

创建Paymaster

Requires an authenticated session (

slot auth login

) and a team with credits.

slot paymaster <name> create --team <team> --budget <amount> --unit CREDIT

The budget is deducted from the team's credit balance. 1 CREDIT = $0.01 USD.

需要已认证的会话（

slot auth login

）以及拥有可用额度的团队。

slot paymaster <name> create --team <team> --budget <amount> --unit CREDIT

预算将从团队的额度余额中扣除。 1 CREDIT = 0.01美元。

Policy Management

策略管理

Policies define which contracts and entrypoints the paymaster will sponsor.

策略定义了Paymaster将为哪些合约和入口点提供手续费赞助。

Add from preset (recommended)

从预设添加（推荐）

Use verified contract presets from the Dojo ecosystem:

slot paymaster <name> policy add-from-preset --name <preset-name>

Presets are maintained at https://github.com/cartridge-gg/presets/tree/main/configs

使用Dojo生态中的已验证合约预设：

slot paymaster <name> policy add-from-preset --name <preset-name>

预设维护地址：https://github.com/cartridge-gg/presets/tree/main/configs

Add a single policy

添加单个策略

slot paymaster <name> policy add --contract <address> --entrypoint <entry-point>

slot paymaster <name> policy add --contract <address> --entrypoint <entry-point>

Add from JSON

从JSON添加

slot paymaster <name> policy add-from-json --file <path>

JSON format:

json

[
  {
    "contractAddress": "0x1234...abcd",
    "entrypoint": "move_player"
  },
  {
    "contractAddress": "0x5678...efgh",
    "entrypoint": "attack",
    "predicate": {
      "address": "0x9abc...1234",
      "entrypoint": "check_attack_eligibility"
    }
  }
]

Predicates are optional. When present, the predicate contract is called first — the transaction is only sponsored if it returns

true

slot paymaster <name> policy add-from-json --file <path>

JSON格式：

json

[
  {
    "contractAddress": "0x1234...abcd",
    "entrypoint": "move_player"
  },
  {
    "contractAddress": "0x5678...efgh",
    "entrypoint": "attack",
    "predicate": {
      "address": "0x9abc...1234",
      "entrypoint": "check_attack_eligibility"
    }
  }
]

Predicate为可选配置。当配置Predicate时，会先调用该合约——只有当合约返回

true

时，交易才会获得手续费赞助。
