Symbiosis

Inspiration

Probably this tweet thread(https://tinyurl.com/ecjfp6zw) was an inspiration to make a Solana integration

We have already been creating a cross-chain product for almost a year but decided that it would be cool if we can jump into a hackathon without any prior knowledge of Solana or any Rust developer in the team, and ship the Solana integration less than a month

What it does

It allows to do a cross-chain swap from any chain and any token to native SOL token on Solana in just a one-click(on current dev stand 2 clicks), no more need for bridges (trying to find a Wormhole website), you just ape to Solana in 2 clicks, that's simple

Under the hood we utilize :

wrap tokens --we wrap sol token to BSC creating sSOL on Binance smart chain
AMM dex -- in the current example its BNB/sSOL pair on finance smart chain
Routing mechanism -- to route any token on BSC to BNB, basically any token/BNB swap
p2p relayers network - listening for unwrap events on both chains, and then proceed MPC/TSS (threshold signature signing) procedure on the destination chain

How we built it

Challenges we ran into

There was some problems with solana addresses and different types (EVM its addresses and in solana bytes)
We have to modify our TSS library to be compatible with Solana cryptography
Learning Solana in a month was a real journey I would say, but a remarkable one

Accomplishments that we're proud of

Building the working solution for Any token on a connected chain to SOL swap in a month.

What we learned

Solana is cool but hard

What's next for Symbiosis

The same thing we do every night, Pinky, try to take over the cross-chain world but seriously implement the same AMM logic we have on BSC, but on Solana, so we can do Sol->Any token swap (it's 80% ready but we did not have enough time to integrate it with our frontend) and then build a routing mechanism, so it will be Any to Any token swap
