predict.fun SDK for Rust

Port of the TypeScript SDK for predict.fun prediction market

Overview

This SDK provides functionality to:

• Build and sign orders using EIP-712
• Interact with predict.fun smart contracts on BNB Chain
• Calculate order amounts with proper precision
• Manage positions (split, merge, redeem)

Example

use predict_sdk::{OrderBuilder, ChainId};
use alloy::signers::local::PrivateKeySigner;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let signer = PrivateKeySigner::random();
    let builder = OrderBuilder::new(ChainId::BnbTestnet, Some(signer), None)?;

    // Build and place orders...

    Ok(())
}
