Auto Settlements

Master Wallet Create Rule

This endpoint allows you to create a new auto-settlement rule for a specific wallet. By providing the necessary parameters in the request body, you can define the conditions and actions for the auto-settlement process.

Request Body Parameters

Parameter	Type	Required	Description
type	string	No	The settlement rule type: `withdraw`, `swap`, `gateway`, or `earn`. Recommended on every create; rules saved without it keep the legacy inferred behavior. `withdraw` settles each deposited source asset as-is to `destination.address` on the source blockchain (address required, and `destination.blockchain` must equal the source blockchain). `swap` converts to a different asset or chain. `gateway` requires `isGateway: true`; `earn` requires `isReward: true`.
name	string	No	The name of the auto-settlement rule. A descriptive title reflecting its purpose.
isActive	boolean	No	Whether the rule is enabled. Defaults to `true`.
order	string	No	Routing preference for the swap leg. Possible values: `FASTEST`, `CHEAPEST`, `RECOMMENDED`, `NO_SLIPPAGE`. Defaults to `RECOMMENDED`, and is ignored for gateway and earn rules.
slippageTolerance	string	No	The acceptable slippage tolerance (as a percentage). Example: `"5"` = 5% tolerance. Defaults to `"0"`; use `"-1"` for unlimited.
isGateway	boolean	No	Route the settlement through Circle’s Gateway into the unified USDC balance. Required to be `true` when `type` is `gateway`.
isReward	boolean	No	Settle into an Earn position instead of transferring the funds out. Required to be `true` when `type` is `earn`. Mainnet only, and cannot be combined with `isGateway`.
rewardProvider	string	Conditional	Required when `isReward` is `true`. One of `aave` or `compound`. Every source asset must be supported by that provider on the wallet’s blockchain.
rewardType	string	No	Strategy class (`defi`). Optional — defaults from the resolved product.
useTransactionAmount	boolean	No	Defaults to `false`, which settles the address’s current balance of the source asset. Set to `true` to settle only the amount of the deposit that triggered the rule.
deductionPercentage	string	No	Percentage withheld from the settled amount before execution, e.g. `"2.5"` leaves 2.5% behind. Defaults to `"0"`.
inheritance	object	No	Controls which child addresses this master-wallet rule cascades to. Omit it to keep the legacy behavior, where the rule applies to the master wallet and every child address.
├─ mode	string	Yes	One of `master_only`, `all_children`, or `selected_children`.
├─ childAddressIds	array of strings	Conditional	Required and non-empty when `mode` is `selected_children`. Each address must be active, belong to this business and network, and match the wallet’s chain family.
source	object	Yes	Details about the source of the settlement.
├─ assets	array of strings	Yes	List of asset symbols this rule settles (e.g., `["USDC"]`). Source assets cannot overlap with another rule on the same blockchain.
├─ minAmount	string	No	The minimum amount required for settlement (e.g., `"1"`). Defaults to `"0"`.
├─ maxAmount	string	No	The maximum amount that can be settled (e.g., `"1000"`). Defaults to `"-1"` (unlimited).
├─ blockchain	string	No	Ignored on create — always set to the wallet’s own blockchain.
destination	object	Yes	Details about the destination of the settlement.
├─ blockchain	string	Yes	The blockchain network for the destination.
├─ asset	string	Yes	The asset the settlement is directed to. Gateway rules are forced to `USDC`.
├─ address	string	Conditional	The address the settlement is sent to. Required for `withdraw` rules. When omitted, the smart fallback applies: same-chain settlements reuse the deposit address, EVM-to-EVM settlements reuse the same address on the destination chain, and other cross-chain settlements use the destination chain’s master wallet address.
