Deployment	Implementation	UIs	Parameters	Oracle
SigmaUSD on Ergo Since: February 2021	Agenor	sigmausd.io tokenjay.app/app/#ageusd	Peg: USD BaseCoin: ERG Fee: 2% Minimum Reserve Ratio: 400% Maximum Reserve Ratio: 800% UI Fees: 0% - 0.25%	Ergo Oracle Pools Decentralized operation open to anyone who stakes ERG into the oracle pool Update period: ~12 minutes (2 blocks) Maximum price change per update: 0.49%, unless the price discrepancy is greater than 50%
COTI's Djed on Cardano Since: February 2023	Minimal Djed in Plutus	www.djed.xyz/	Peg: USD BaseCoin: ADA Fee: 1.5% Minimum Reserve Ratio: 400% Maximum Reserve Ratio: 800% Operator Fee: 25 ADA Minimum Transaction Limits: * Buy SC: 1000 SC * Sell SC: 200 SC * Buy RC: 1000 RC * Sell RC: 500 RC (Enforced at the UI.)	Operation by COTI More than 6 data sources Sources are checked every 15 minutes. Outliers are removed if the prices they provide differ from the median of the 6 prices by more than a parameter currently set to 0.06%. If more than 3 sources remain, the median of their prices is computed, signed and made available by the operator. The signed price remains valid for 15 minutes.
Milkomeda Djed Dollar on Milkomeda-C1 Since: April 2023	Belus	milkomeda-c1.djed.one/	Peg: USD BaseCoin: mADA Fee: 1.5% Minimum Reserve Ratio: 400% Maximum Reserve Ratio: 800% UI Fee: 0% Stable Order Treasury Fee: 0.25% initially and linearly decreasing to 0%. Maximum Transaction Limit: ~ 10000 USD worth of mADA (enforced by the contract.)	MOO Oracle Operation by Milkomeda Nodes Sources are checked every ~10 seconds Outliers are removed if the prices they provide differ from the mean by more than 2 standard deviations. The mean of the remaining prices is calculated. If the new mean price differs from the last price posted on the blockchain by more than 1%, the new mean price is posted and the price is updated on the blockchain.
Zephyr Stable Dollar (ZSD) on Zephyr Since: October 2023	Zephyr	https://www.zephyrprotocol.com/	Peg: USD BaseCoin: ZEPH Fee: TODO Minimum Reserve Ratio: 400% Maximum Reserve Ratio: 800%	TODO
Ethereum Classic Stable Dollar	Belus	etc.djed.one (Under construction)	Peg: USD BaseCoin: ETC Fee: 1.25% Minimum Reserve Ratio: 300% Maximum Reserve Ratio: 1000% UI Fee: 0% Stable Order Treasury Fee: 0.25% initially and linearly decreasing to 0%. Maximum Transaction Limit: ~ 10000 USD worth of ETC (enforced by the contract.)	HebeSwap Oracle Operation by HebeSwap. Sources checked include CMC, CoinGecko and Binance. Sources are checked every 30s by 3 oracle nodes. Each node produces an average price from 3 sources and submits this average to the oracle contract. A node's price is an outlier if differs by more than 0.5% from the others. Outlier prices are removed. If there are at least two prices remaining, their average is computed. Otherwise, no new price is produced. The whole process may take up to a minute. So, new prices are normally posted on chain every 30s, and each new price may be up to 1 minute delayed.
