Reclaim the remaining USDC collateral for options you wrote after the series has been settled. The payout is the writer’s original collateral minus the portion allocated to holder payouts. Contract: ConvallaxCore — 0xc760F8f6B8830463822be9F68eB10e1b5Dace378

​
Function Signature

function claimWriterCollateral(uint256 seriesId) external

​
Parameters

seriesId
uint256
required
The settled option series ID.

Payout Calculation

writerPayout = writerCollateral × writerPoolRemaining / totalCollateral
Where writerPoolRemaining = totalCollateral − holderPool (total collateral minus all holder payouts).
This is a one-shot operation. The writer’s recorded collateral is zeroed after claiming. Call it once per series.

​
Prerequisites

  • The series must be settled
  • The caller must have deposited collateral by previously calling mint() for this series
  • The caller’s recorded collateral must be greater than zero

const core = new ethers.Contract(
  '0xc760F8f6B8830463822be9F68eB10e1b5Dace378',
  ['function claimWriterCollateral(uint256 seriesId) external'],
  signer
);

const tx = await core.claimWriterCollateral(seriesId);
await tx.wait();
