Liquidity Pools:

These tokens are all on the RSK platform. BlinDEX plans to add other stablecoins, and thus liquidity pool currency pairs, "as time goes by".

• WRBTC-BDUS (wRBTC on RSK <--> BlinDEX USD on RSK)
• WRBTC-BDEU (wRBTC on RSK <--> BlinDEX EUR on RSK)
• ETHs-BDUS (Sovryn's ETHs on RSK <--> BlinDEX USD on RSK)
• ETHs-BDEU (Sovryn's ETHs on RSK <--> BlinDEX EUR on RSK)
• BDEU-BDUS (BlinDEX EUR on RSK <--> BlinDEX USD on RSK)
• BDX-BDUS (BlinDEX DAO token on RSK <--> BlinDEX USD on RSK)
• BDX-BDEU (BlinDEX DAO token on RSK <--> BlinDEX EUR on RSK)
• WRBTC-BDX (wRBTC on RSK <--> BlinDEX DAO token on RSK)
• ETHs-BDX (Sovryn's ETHs on RSK <--> BlinDEX DAO token on RSK)

Q.) Do I need a BDX token for swapping?

A.) No, unless you are trying to swap to or from BDX directly. BDX is only used when Minting/Redeeming in order to make up for the collateral ratio and keep the tokens stable.

Q.) What are the fees for swapping?

A.) There is a small fee which is typically 0.3%. The fee will be automatically calculated once you choose the tokens you would like to swap. 0.25% will be rewarded to the liquidity provider while the remaining 0.05% goes to the protocol’s treasury.

We’re creating truly decentralized stables: pegged to your home currency, but collateralized by ETH & BTC (and other select, decentralized large-cap coins in the future).

We made sure it’s disconnected from any existing, centralized stables (so it can not be blacklisted, paused, censored, or otherwise affected by any centralized authority). Even our infrastructure layer is running on StackOS, the decentralized cloud.

We’re deriving from the great work done by the FRAX team, who managed to build very robust foundations for a partially collateralized, algorithmic stablecoin.
We’ve added some additional logic to support multiple fiat currencies and not just USD, as well as changed the collateral to be only fully decentralised BTC & ETH.

We've also refined some of the redemption mechanisms in order to remove any incentivize for a "bank run" and have a fairer collateral distribution upon redemption.

Frax uses Uniswap (ETH, USDT, USDC time-weighted average prices) and Chainlink (USD price) oracles.

The specific BD-Stable token naming convention is BD + country code (e.g. BDAU for Australian Dollar Stablecoin). We will be gradually releasing a few major currencies (BDEU, BDAU and BDUK) and will add more stables based on community feedback.

[BDX is their DAO token]

50% of the tokens [premined]^[1]

[of that 50%,] 35% is dedicated for partnerships, integrations and new BD-Stables
[of that 50%,] 15% is reserved (with appropriate cliff and time locking) for the core team that will continue developing and maintaining the protocol.

[The other] 50% are farmed via liquidity mining program over 5 years
[Years: Y1 - 20%, Y2 - 12.5%, Y3 - 10%, 4 - 5%, Y5 - 2.5%]
