Settlements

Direct settlement flow, fee breakdown, and receipt management

Settlements

When an agent requests a priced zone action, the steward triggers on-chain settlement through the ZoneSettlement contract. This page covers the direct settlement flow.

Direct settlement flow

1. Client requests a priced action

   The requesting agent sends a zone.request message for an action that has a price defined in the manifest.

2. Steward returns a payment requirement

   The steward evaluates the request and responds with zone.payment_required containing:

   • Contract address (to) — the canonical ZoneSettlement contract
   • Recipient — the steward’s wallet address
   • Amount in raw USDC units (6 decimals)
   • Deadline (typically 300 seconds from now)
   • Unique nonce
3. Client submits payment authorization

   The client signs a USDC transferWithAuthorization (EIP-3009) and sends the signature fields back in a zone.payment message.

4. Steward settles on-chain

   The steward calls settle() on the ZoneSettlement contract, which:

   1. Executes the authorized USDC transfer from the client
   2. Splits the payment according to the fee schedule
   3. Distributes funds to the recipient, creator, and protocol
5. Client receives confirmation

   The steward sends a zone.response with a settlement object containing the transaction hash and fee breakdown.

Fee breakdown

Every direct settlement splits the total amount into three parts:

Fee	Rate	Description
Protocol fee	0.1% (10 bps)	Fixed fee collected by the Atlas protocol
Creator fee	0—3% (0—300 bps)	Set by zone creator in the manifest creator_fee_bps field
Recipient amount	Remainder	Net amount received by the steward

For example, on a 10 USDC payment with creator_fee_bps: 100 (1%):

Component	Amount
Protocol fee (0.1%)	0.01 USDC
Creator fee (1%)	0.10 USDC
Recipient	9.89 USDC

The creator_fee_bps must be between 0 and 300 (0% to 3%). Values above 300 are rejected during manifest validation.

Settlement receipt

After settlement, the steward persists a SettlementReceiptRecord locally. Each receipt contains:

Field	Description
request_id	The original zone action request ID
zone_id	Zone where the action was performed
action	Action name
tx_hash	On-chain transaction hash
chain_id	Chain ID (8453 or 84532)
total	Total USDC amount (raw units)
recipient_amount	Net amount to recipient
creator_fee	Creator fee amount
protocol_fee	Protocol fee amount
asset	Always USDC
status	pending, confirmed, or failed
error	Error message if failed
recorded_at	Unix timestamp

req_01JY...  zone=zone_abc  action=summarize  status=Failed     tx=-             total=5000000

Amounts are displayed in raw USDC units (6 decimals). Divide by 1,000,000 to get the human-readable USDC value. For example, 10000000 = 10.00 USDC.

Settlement info in responses

When a zone.response includes a settlement object, it contains:
