sDAI Yield Dashboard – Real-Time APR Analytics on Gnosis Chain

sDAI Yield Validator is a transparent analytics dashboard that tracks and explains the yield earned by sDAI holders on Gnosis Chain.

All calculations are derived directly from on-chain data and explained on the methodology page, so you can verify every number yourself.

Frequently Asked Questions

What is the current sDAI yield on Gnosis Chain?

The sDAI APR on Gnosis Chain is calculated as the Sky Savings Rate (SSR) multiplied by the bridge amplification ratio. Because more DAI is locked in the Ethereum–Gnosis bridge than is minted as sDAI, holders earn yield on a larger pool, boosting their effective rate above the base SSR. Check the dashboard for the live rate.

How is sDAI APR different from the on-chain vaultAPY?

The calculated sDAI APR is derived in real-time from on-chain inputs (SSR rate × amplification ratio). The on-chain vaultAPY() only updates every ~72 hours when an epoch claim fires, so it can be stale. This dashboard shows both values and the gap between them.

What is the Sky Savings Rate (SSR)?

The Sky Savings Rate (SSR) is the base savings rate set by Sky Protocol (formerly MakerDAO) on Ethereum mainnet. It replaced the DSR (Dai Savings Rate) on September 4, 2024. It is stored as a per-second compounding rate (ray, 10²⁷ fixed-point) and converted to APY using: (rate / 10²⁷) ^ 31,557,600 − 1.

What is bridge amplification and why does sDAI earn more than the SSR?

Bridge amplification occurs because all DAI locked in the Ethereum–Gnosis bridge earns the SSR, but only a portion of that bridged DAI is represented as sDAI on Gnosis Chain. Since the yield from the entire bridge pool is distributed among sDAI holders (a smaller group), they effectively earn more than the base SSR. The amplification ratio = Bridged DAI / sDAI totalAssets.

How often is sDAI yield data updated?

Live metrics are refreshed every 15 minutes using current on-chain data. Historical data points are captured daily at midnight UTC. Epoch claim events are indexed in real-time from the BridgeInterestReceiver contract on Gnosis Chain.

Can I access sDAI yield data programmatically?

Yes. The sDAI Yield Validator exposes a free REST API at sdaiyield.com/api/ with endpoints for current data, historical datasets, holder rankings, and more. Interactive documentation is available at sdaiyield.com/api/docs (Swagger UI).

How does sDAI yield compare to Spark Protocol rates?

Spark Protocol and other DeFi frontends typically display the on-chain vaultAPY(), which can be stale by up to 72 hours. The sDAI Yield Validator calculates the actual effective APR from on-chain inputs in real-time, providing a more accurate picture of current yield.

Can I verify the sDAI yield calculations independently?

Yes. All data comes from public on-chain sources. You can read the SSR rate from the SSR contract on Ethereum, check bridged DAI in the bridge escrow, and read sDAI totalAssets from the vault on Gnosis Chain. All contract addresses and methodology are documented on the Methodology page.
