Strike SDK

Rust SDK for Strike prediction markets on BNB Chain.

Strike is a fully on-chain prediction market protocol using Frequent Batch Auctions (FBA) for fair price discovery. Traders buy and sell binary outcome tokens (YES/NO) on whether an asset’s price will be above or below a strike price at expiry.

Quick Start

use strike_sdk::prelude::*;

// Read-only client
let client = StrikeClient::new(StrikeConfig::bsc_testnet()).build()?;
let markets = client.indexer().get_markets().await?;

// Trading client (with wallet)
let client = StrikeClient::new(StrikeConfig::bsc_testnet())
    .with_private_key("0x...")
    .build()?;

// Approve USDT spending
client.vault().approve_usdt().await?;

// Place orders
let orders = client.orders().place(1, &[
    OrderParam::bid(50, 1000),
    OrderParam::ask(60, 1000),
]).await?;

Key Concepts

• LOT_SIZE = 1e16 wei ($0.01 per lot)
• Ticks are 1–99, representing $0.01–$0.99 probability
• 4-sided orderbook: Bid, Ask, SellYes, SellNo
• Batch auctions: Orders are collected and cleared in batches
• All fills pay the clearing tick, not the limit tick

Features

• nonce-manager (default) — shared nonce management via NonceSender
