Basket Claim

Claim payout from a settled PolyBaskets basket via vara-wallet.

Setup

MAINNET ONLY. Run vara-wallet config set network mainnet before anything else. NEVER switch to testnet — there are no contracts there.

vara-wallet config set network mainnet
BASKET_MARKET="0xe5dd153b813c768b109094a9e2eb496c38216b1dbe868391f1d20ac927b7d2c2"
BET_LANE="0x35848dea0ab64f283497deaff93b12fe4d17649624b2cd5149f253ef372b29dc"
_PB="${POLYBASKETS_SKILLS_DIR:-skills}"
IDL="$_PB/idl/polymarket-mirror.idl"
BET_LANE_IDL="$_PB/idl/bet_lane_client.idl"

Pre-Check Workflow

1. Verify settlement is finalized

vara-wallet call $BASKET_MARKET BasketMarket/GetSettlement \
  --args '[<basket_id>]' --idl $IDL

Check the result:

• status: "Finalized" — ready to claim
• status: "Proposed" — challenge window not yet passed, or nobody has finalized yet. Anyone can call FinalizeSettlement after challenge_deadline; before that, wait.
• Error SettlementNotFound — not yet settled

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

Get your hex address first (SS58 won't work for actor_id args):

MY_ADDR=$(vara-wallet balance | jq -r .address)

2. Verify position exists and is unclaimed

# VARA lane
vara-wallet call $BASKET_MARKET BasketMarket/GetPositions \
  --args '["'$MY_ADDR'"]' --idl $IDL | jq '.result[] | select(.basket_id == <basket_id>)'

# BET lane
vara-wallet call $BET_LANE BetLane/GetPosition \
  --args '["'$MY_ADDR'", <basket_id>]' --idl $BET_LANE_IDL

Check claimed: false.

Claim (VARA Lane)

For baskets with asset_kind: "Vara":

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

Returns u128 — payout amount in minimal VARA units (divide by 10^12 for VARA).

Example

# Claim from basket 0
PAYOUT=$(vara-wallet --account agent call $BASKET_MARKET BasketMarket/Claim --voucher $VOUCHER_ID \
  --args '[0]' --idl $IDL)
echo "Payout: $PAYOUT"

Claim (BET Token Lane)

For baskets with asset_kind: "Bet":

vara-wallet --account agent call $BET_LANE BetLane/Claim --voucher $VOUCHER_ID \
  --args '[<basket_id>]' --idl $BET_LANE_IDL

Returns u256 — payout amount in BET token units.

Example

# Claim from basket 1 via BET lane
vara-wallet --account agent call $BET_LANE BetLane/Claim --voucher $VOUCHER_ID \
  --args '[1]' --idl $BET_LANE_IDL

Payout Calculation

payout = shares * (settlement_index / entry_index)

The payout_per_share is pre-computed in the Settlement struct during proposal. You can preview your expected payout before claiming:

# Get settlement payout_per_share
SETTLEMENT=$(vara-wallet call $BASKET_MARKET BasketMarket/GetSettlement \
  --args '[<basket_id>]' --idl $IDL)
echo $SETTLEMENT | jq '.result.ok.payout_per_share'

See ../references/index-math.md for detailed formula and examples.

Verify After Claim

# Check position is now claimed
vara-wallet call $BASKET_MARKET BasketMarket/GetPositions \
  --args '["'$MY_ADDR'"]' --idl $IDL | jq '.result[] | select(.basket_id == <basket_id>) | .claimed'

# Check VARA balance increased
vara-wallet balance
