Slot Paymaster

Manage paymasters that sponsor transaction fees, enabling gasless experiences for users. Zero integration required — when enabled, eligible transactions are automatically sponsored.

Availability

• Testnet: Automatically enabled, no setup required

• Mainnet: Self-served via Slot CLI

Creating a 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.

Budget Management

Increase budget

slot paymaster <name> budget increase --amount <amount> --unit CREDIT

Decrease budget

slot paymaster <name> budget decrease --amount <amount> --unit CREDIT

Policy Management

Policies define which contracts and entrypoints the paymaster will sponsor.

Add from preset (recommended)

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

Add a single policy

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

Add from JSON

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

JSON format:

[ { "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 .
