Solayer Token Price Feeds Guide

This guide explains how to fetch real-time price feeds for sUSD, sSOL, and Layer using Pyth Network. It is intended for developers integrating on-chain or off-chain price functionality into applications or smart contracts.

​

Price Feed Sources

Solayer tokens are supported on Pyth Network with live, decentralized price feeds:

How to Use Pyth Price Feeds

You can consume these feeds in two ways: on-chain (Solana programs) and off-chain (apps, bots, bridges, etc).

​

1. On-Chain: Using Real-Time Data in Solana Programs

Solana programs can directly use Pyth’s price data via CPI.

Steps:

1. Locate the Pyth price account from the links above
2. Pass the price account as an input to your smart contract
3. In the contract, deserialize and access:

• price
• confidence_interval
• expo

4. Always validate:

• status == Trading
• the publish time is recent enough (i.e. not stale)

​

2. Off-Chain: Using Real-Time Price Data

Pyth recommends using hermes-client or calling the get_price_updates API for secure off-chain usage.

​

get_price_updates API (Signed & Verifiable)

To fetch signed, binary-encoded price updates:

curl "https://hermes.pyth.network/api/get_price_updates?ids[]=Crypto.sUSD/USD::RR&binary=true"

This method is suitable for:

• Secure data ingestion
• Cross-chain bridging
• Price verification in backend systems

​

Deprecated / Not Recommended

• price-service-sdk is deprecated and should not be used.
• The api/latest_price HTTP endpoint is still functional but not recommended for production use:
  • It is not cryptographically verified
  • It may be deprecated in the future
  • Use only for internal dashboards or quick prototyping
