Developer Overview

SentiDex exposes its attention index and market data for integration into third-party products. This section covers the available interfaces.

What you can build

Dashboards — embed live attention scores and position prices
Alerts — trigger notifications when attention shifts above a threshold
Quant strategies — consume the index feed as an input signal
Aggregators — include SentiDex data alongside other prediction market sources

Integration options

Method	Best for
On-chain reads	Direct contract reads via Viem/Wagmi for trustless data
REST API	Server-side integrations, dashboards, alerting
WebSocket feed	Real-time streaming of price and attention updates

Contract addresses (Sepolia)

Contract addresses are generated at deploy time and updated here after each deployment. Check deployments.json in the contracts repo for the latest.

Contract	Address
`Ledger`	`0x...`
`LedgerViews`	`0x...`
`MarketMakerHub`	`0x...`
`MockUSDC`	`0x...`

Reading data on-chain

The primary read contract is LedgerViews. It aggregates market and position state into UI-friendly snapshot structs, avoiding the need for multiple fragmented calls.

import { createPublicClient, http } from 'viem'
import { sepolia } from 'viem/chains'
import { LEDGER_VIEWS_ABI } from './abis'
 
const client = createPublicClient({ chain: sepolia, transport: http() })
 
const snapshot = await client.readContract({
  address: LEDGER_VIEWS_ADDRESS,
  abi: LEDGER_VIEWS_ABI,
  functionName: 'getMarketSnapshot',
  args: [marketId],
})
