@seer-pm/react

React hooks for interacting with Seer prediction markets.

This package exposes reusable hooks that work with @seer-pm/sdk and Wagmi.

Hooks

Markets

• useMarket — Single market by ID and chain. Prefers subgraph data, falls back to on-chain.
• useGraphMarket — Market from subgraph by marketId and chainId.
• useMarketQuestions — Overrides a market’s question data with on-chain data (e.g. best_answer, reopened status).
• useMarkets — List of markets with filters: type, marketName, categoryList, marketStatusList, verificationStatusList, chainsList, creator, participant, orderBy, orderDirection, marketIds, limit, page, etc.

Pools & liquidity

• useMarketPools — Pools for a market (Swapr on Gnosis, Uniswap on Mainnet/Optimism/Base).
• useMarketHasLiquidity — Whether a market (or a specific outcome) has liquidity.
• useMarketOdds — Current odds for a market; requires liquidity check to be resolved.
• useComputedPoolAddresses — Computed pool addresses for a market’s token pairs.

Tokens

• useTokenInfo — Metadata for a single token (address, chain).
• useTokensInfo — Metadata for multiple tokens; also fills per-token cache for useTokenInfo.
• useTokenBalance — Balance of a token for an owner (supports native token).
• useTokenBalances — Balances for multiple tokens for an owner.

Trading & quotes

• useQuoteTrade — Unified quote for buy/sell: uses CoW (or instant swap) when enabled or for Seer Credits, otherwise Swapr (Gnosis) or Uniswap (Mainnet/Optimism/Base).
• useCowQuote — CoW Protocol quote.
• useSwaprQuote — Swapr (Algebra) quote (Gnosis).
• useUniswapQuote — Uniswap quote (Mainnet, Optimism, Base).

Approvals

• useMissingApprovals — Tokens that still need approval for a given spender/amounts (supports ERC-7702).
• useMissingTradeApproval — Wrapper over useMissingApprovals for a single trade (base currency and approve address from trade).
• useApproveTokens — Mutation to approve a token for a spender (with optional tx notifier).

Positions (split / merge / redeem)

• useSplitPosition — Split collateral into outcome tokens. Supports legacy and ERC-7702 (batched approvals + split).
• useMergePositions — Merge outcome tokens back to collateral. Supports legacy and ERC-7702.
• useRedeemPositions — Redeem winning/merged positions. Supports legacy and ERC-7702.

Account / chain support

• useCheck7702Support — Whether the connected account supports ERC-7702 (atomic batch) for the current chain.
