Although stablecoins were already seeing strength before the decentralized finance season, they came to be seen as an investment highlight during the boom of DeFi.
After all, it was precisely in this area that stable assets started to make profits for their holders. As a result of Ethereum being the main token creation blockchain in the market, most of these assets are in its network.
Undoubtedly, the stablecoin market will continue to grow. However, for a decentralized exchange today, the DEX project did not fully consider the parity of the tokens.
Get to know Smoothy
Smoothy is an exchange solution for assets backed by the same underlying asset, for example, stablecoins. Smoothy uses only one pool consisting of a set of interoperable protocol smart contracts deployed on Ethereum-compatible blockchains.
The platform solves the problems of the existing protocols by offering a pool to exchange all tokens backed by real-world assets, such as USDT and USDC.
Smoothy implements a simple and efficient swap that supports a long list of assets in the pool. For each token in the pool, it has two swap parameters:
Soft weight – the highest percentage of the token until it becomes unbalanced (imposing penalty)
Hard weight – the percentage of a token should never exceed, which should be equal to or greater than soft weight.
One of the great rivals of the Smoothy platform is Curve.fi, which to calculate the number of tokens returned, needs to calculate the invariant together using the percentage data of all tokens. As a result, Curve.fi presents more gas rates in data and computing.
These factors are not seen in Smoothy, as it uses soft/hard weights and a bonding curve. This makes the protocol save computational costs since the exchange of two tokens will only need to perform calculations on two tokens, including the penalty.
