Seed a market - Voiz Markets SDK

Open the pools so people can trade — quote collateral first, then call market.seed. There is no client.seedMarket. Seeding always lives on the market instance: client.market(addr).seed(…).

Prerequisites

A created market address and its outcome (wrapped) tokens
Collateral ≥ quoteSeed(…).totalCollateral
Connected wallet as owner

Steps

1. Normalize odds and quote

Odds are basis points that sum to ~10_000 (keep each outcome between 1% and 99%). Normalize, then quote:

import { normalizeOddsBps, quoteSeed } from '@voiz/markets-sdk'
import { parseUnits } from 'viem'
import { useVoiz } from '@voiz/markets-sdk/react'

const { client } = useVoiz()

const seedWei = parseUnits('100', 18) // match your collateral decimals
const oddsBps = normalizeOddsBps([60, 40]) // e.g. 60% / 40%

const { splitAmount, poolCollateral, totalCollateral } = quoteSeed({
  seedWei,
  oddsBps,
})
// Show totalCollateral in the UI before the user confirms.

2. Seed the market

const market = client.market(marketAddress)

const {
  plan,
  splitResult,
  outcomeResults,
  splitHashes,
  outcomeHashes,
} = await market.seed({
  outcomeTokens, // real outcomes only — not Invalid
  seedWei,
  oddsBps,
  owner: yourAddress,
})

seed splits once, then submits one batch per outcome. Check progress anytime:

const status = await market.seedStatus() // 'none' | 'partial' | 'seeded'

Tip

quoteSeed only needs seedWei + oddsBps — safe before you have tokens. Fund totalCollateral (split + pool side), not just seedWei. Same call works without React via client.market(addr).seed(…).
