@predixia/sdkv0.1.0

Predixt SDK

Read markets, place bets, settle and claim. A TypeScript SDK on top of @solana/kit that wraps the Predixt program behind a tiny, fully-typed client.

Install

$ pnpm add @predixia/sdk @solana/kit

Live in four lines

Point the client at any RPC and you are ready to read markets and send transactions. No boilerplate, no manual account wrangling.

setup.ts

import { createSolanaRpc, createSolanaRpcSubscriptions } from "@solana/kit";
import { PredixtClient, Side, computeOdds } from "@predixia/sdk";

const sdk = new PredixtClient({
  rpc: createSolanaRpc("https://api.mainnet-beta.solana.com"),
  rpcSubscriptions: createSolanaRpcSubscriptions("wss://api.mainnet-beta.solana.com"),
});

Fully typed client

Generated from the on-chain IDL. Every account, instruction and enum is type-safe.

PDAs & ATAs handled

Build instructions without deriving program addresses or token accounts by hand.

Live subscriptions

Subscribe to a market and get pushed updates the moment the odds move.

Parimutuel math built in

Odds, payouts and settlement helpers that match the program byte-for-byte.

Read markets & odds

// Read every open market and its live odds
const markets = await sdk.getMarkets();

for (const m of markets) {
  const { probYes } = computeOdds(m.data.yesTotal, m.data.noTotal);
  console.log(m.address, `${Math.round(probYes * 100)}% YES`);
}

Place a bet

// Place a bet (signer = a Kit wallet / TransactionSigner)
const ix = await sdk.placeBet(signer, market, Side.Yes, 1_000_000n);
const signature = await sdk.send(signer, [ix]);

Stream live odds

// Stream live odds as money flows in
const ctrl = new AbortController();
await sdk.subscribeMarket(market, (m) => {
  console.log(computeOdds(m.data.yesTotal, m.data.noTotal));
}, ctrl.signal);

Build on Predixt

Bots, dashboards, alt frontends. If it speaks Solana, it can speak Predixt.
