Question 1

What does RedStone do?

Accepted Answer

RedStone is a modular oracle network designed to overcome the limitations of traditional push-based oracle models like Chainlink's Data Feeds. Instead of continuously updating prices on-chain regardless of whether anyone needs them (wasting gas on every update), RedStone introduces two delivery models: RedStone Core (calldata model) and RedStone Classic (push model). This architectural flexibility, combined with coverage of over 1,000 price feeds — including assets that Chainlink and Pyth do not cover — makes RedStone the oracle of choice for DeFi protocols working with liquid staking tokens, liquid restaking tokens, real-world assets, and long-tail cryptocurrency markets.

For Nigerian DeFi developers building sophisticated protocols, RedStone fills critical gaps that competing oracles leave unfilled. Chainlink and Pyth cover the most liquid, highest-volume assets (BTC, ETH, major stablecoins) but have limited coverage for the long-tail of the crypto market. RedStone's 1,000+ feeds include emerging DeFi tokens, liquid staking derivatives, and RWA tokens that are becoming central to advanced DeFi strategies. A Nigerian protocol supporting diverse collateral types needs an oracle that covers the full asset universe its users hold.

The RedStone Core model works by embedding signed price data in transaction calldata rather than storing it in smart contract state. When a user calls a contract function that needs a price — for example, depositing collateral into a lending protocol — the frontend fetches a signed price package from RedStone's data availability layer and appends it to the transaction calldata. The smart contract (wrapped with RedStone's EVM connector) extracts and verifies the price from calldata before executing the main logic. The key advantage: gas is only consumed for pricing when an actual transaction occurs, not on every price update interval. For protocols with many supported assets but infrequent individual usage, this dramatically reduces oracle costs.

The RedStone Classic model behaves like traditional push oracles — price updates are pushed to on-chain contracts on a schedule or when price deviation thresholds are exceeded. This is suitable for applications that need on-chain prices accessible to any contract without requiring users to attach price data to their transactions. RedStone Classic is backward-compatible with the Chainlink AggregatorV3Interface, allowing protocols to switch from Chainlink to RedStone without changing their consumer contract code.

LST (Liquid Staking Token) and LRT (Liquid Restaking Token) price feeds are a RedStone specialty. Tokens like stETH, wstETH, weETH, rsETH, and ezETH are yield-bearing — their value grows over time as staking rewards accrue. Correctly pricing these tokens for DeFi collateral purposes requires tracking the current exchange rate against the underlying asset (ETH), not just the DEX spot price, which can diverge. RedStone's LST feeds specifically handle this exchange-rate-based pricing, making them more accurate than generic price feeds for yield-bearing assets.

RWA (Real-World Asset) token feeds cover tokenized government bonds, money market funds, and other yield-bearing traditional finance instruments increasingly appearing in DeFi. Nigerian platforms building RWA-backed stablecoins or yield products can use RedStone's RWA feeds to maintain accurate on-chain valuations without custom oracle infrastructure.

RedStone is entirely free to use for standard feeds. The @redstone-finance/evm-connector npm package and corresponding Solidity library are open source and integrate into any EVM project. Nigerian developers can start building with RedStone oracles in a few hours — the documentation includes comprehensive examples, the testnet deployments are available for integration testing, and the team is responsive to questions in their developer Discord.

Question 2

How much does RedStone cost?

Accepted Answer

RedStone is free to use. Free to use. Core and Classic models available at no charge. Enterprise custom SLA pricing available.

Question 3

How do I authenticate with the RedStone API?

Accepted Answer

None (on-chain SDK integration)

Question 4

Is there a rate limit on RedStone?

Accepted Answer

No rate limit; data delivered via transaction calldata or on-chain push

Question 5

Does RedStone offer a sandbox or test mode?

Accepted Answer

Yes — RedStone provides a sandbox or test environment so you can integrate and test before going live.

Question 6

What is RedStone best suited for?

Accepted Answer

Nigerian DeFi developers needing flexible oracle integration — especially for long-tail assets, LSTs, and RWA tokens not covered by Chainlink or Pyth.

Question 7

Is there anything else I should know before integrating RedStone?

Accepted Answer

RedStone uses an innovative data delivery model: price data is attached to transaction calldata (RedStone Core) or pushed on-chain (RedStone Classic). Strong coverage of LSTs, LRTs, and yield-bearing tokens.

Question 8

Where can I find RedStone's documentation?

Accepted Answer

The official API documentation is at https://docs.redstone.finance/. The provider's website is https://redstone.finance/.
