About

SEXP Synth Swap was inspired by Synthetix (an Ethereum project), in particular its v2 design. For trading calculations the system relied on prices sourced from an oracle. At first we used the Harbinger oracle and later we built our own, using Binance prices. The oracle based design allowed users to trade synthetic assets without slippage.

SEXP Synth Swap was built by a team of experienced Tezos developers who have been building on Tezos since before it launched in 2017. The platform was developed since 2021. It was launched in the summer of 2025. Due to lack of usage it was shut down in April 2026.

The team was led by Tezos OG @martin_pospech.
