Basket Settle

Propose and finalize settlement for PolyBaskets baskets. Requires the settler role.

Setup

MAINNET ONLY. Run

vara-wallet config set network mainnet

before anything else. NEVER switch to testnet — there are no contracts there.

bash

vara-wallet config set network mainnet
BASKET_MARKET="0x702395d43248eaa5f1fd4d9eadadc75b0fb1c7c5ae9ea20bf31375fd4358f403"
_PB="${POLYBASKETS_SKILLS_DIR:-skills}"
IDL="$_PB/idl/polymarket-mirror.idl"

Verify Settler Role

Only the address assigned as

settler_role

in the contract config can call settlement methods.

bash

# Check who has settler role
vara-wallet call $BASKET_MARKET BasketMarket/GetConfig --args '[]' --idl $IDL | jq '.settler_role'

# Check agent's address
vara-wallet wallet list | jq -r '.[0].address'

If your address does not match

settler_role

, you cannot settle. Contact the admin.

Settlement Flow

1. Check basket is Active
2. Verify all items have resolved on Polymarket
3. ProposeSettlement → starts 12-minute challenge window
4. Wait for challenge_deadline to pass
5. FinalizeSettlement → basket becomes Settled, users can claim

Step 1: Check Basket Status

bash

vara-wallet call $BASKET_MARKET BasketMarket/GetBasket \
  --args '[<basket_id>]' --idl $IDL | jq '.result.ok.status'

Must be

"Active"

.

Step 2: Check Polymarket Resolution

For each item in the basket, check if the market has resolved on Polymarket:

bash

curl -s "https://gamma-api.polymarket.com/markets?slug=<poly_slug>" | jq '.[0] | {closed, outcomePrices}'

All items must be resolved (

closed: true

) with final prices near 0 or 1.

Step 3: Propose Settlement

Build the

item_resolutions

array — one

ItemResolution

per basket item:

json

{
  "item_index": 0,
  "resolved": "YES",
  "poly_slug": "will-btc-hit-100k",
  "poly_condition_id": "0xabc123...",
  "poly_price_yes": 9900,
  "poly_price_no": 100
}

Rules:

Provide exactly one resolution per basket item
```
item_index
```
is 0-based, must be unique, and within basket items range
```
poly_slug
```
must match the basket item's slug exactly
```
poly_price_yes
```
+
```
poly_price_no
```
should reflect final Polymarket prices in bps
```
resolved
```
is the final outcome:
```
"YES"
```
or
```
"NO"
```
```
poly_condition_id
```
is optional

Example: Propose settlement for a 2-item basket

bash

vara-wallet --account agent call $BASKET_MARKET BasketMarket/ProposeSettlement --voucher $VOUCHER_ID \
  --args '[
    0,
    [
      {
        "item_index": 0,
        "resolved": "YES",
        "poly_slug": "will-btc-hit-100k",
        "poly_condition_id": null,
        "poly_price_yes": 9900,
        "poly_price_no": 100
      },
      {
        "item_index": 1,
        "resolved": "NO",
        "poly_slug": "will-eth-hit-5k",
        "poly_condition_id": null,
        "poly_price_yes": 200,
        "poly_price_no": 9800
      }
    ],
    "Resolved via Polymarket API"
  ]' \
  --idl $IDL

After proposal, the basket enters

SettlementPending

status and the 12-minute challenge window begins.

Step 4: Wait for Challenge Window

bash

# Check challenge deadline
vara-wallet call $BASKET_MARKET BasketMarket/GetSettlement \
  --args '[<basket_id>]' --idl $IDL | jq '.result.ok | {status, challenge_deadline, proposed_at}'

The

challenge_deadline

is a block timestamp. The liveness window is configured in

liveness_ms

(default 720000ms = 12 minutes).

Wait until the current block timestamp exceeds

challenge_deadline

.

Step 5: Finalize Settlement

bash

vara-wallet --account agent call $BASKET_MARKET BasketMarket/FinalizeSettlement --voucher $VOUCHER_ID \
  --args '[<basket_id>]' --idl $IDL

After finalization:

Basket status becomes
```
Settled
```
```
finalized_at
```
is set
Users can now claim payouts via
```
../basket-claim/SKILL.md
```

Verify

bash

vara-wallet call $BASKET_MARKET BasketMarket/GetSettlement \
  --args '[<basket_id>]' --idl $IDL | jq '.result.ok | {status, payout_per_share, finalized_at}'
