Introduction

Sports Markets AMM is an AMM dedicated for trading positional sport markets using Chainlink feeds for price calculation. For each market, there are two or three positions/outcomes (home win, away win, or draw). Additionally, a game can be cancelled which in that case the last provided odds are used to exercise the users' positions.

It's the vision of the Thales Protocol to support Sport markets and the sport AMM integration. This TIP proposes a format that can achieve this in a decentralized manner with the support of Chainlink data feed.

Motivation In the summer of 2021, Thales built markets around the Olympic medal ranking of the Olympics in Tokyo. The markets were supported by Chainlink oracles and we were able to create a unique product within Thales' offering. The markets were successful and the results reliable, this was a first for many within the community where they got the ability to watch and trade on their favourite sporting event in a decentralised way.

Although successful, the orderbook mechanism and gas costs on Ethereum mainnet weren’t an ideal combination when dealing with sports markets making for an inconvenient user experience. Now, with the convenience of layer2 roll-ups, the innovation behind our Sport AMM, and the proven reliance or Chainlink oracle it is in Thales and its community best interest to launch its Overtime platform.

The sport AMM is one of the most anticipated products built on Thales and will allow users to position themselves based on their favourite sports teams through the whole season. The Overtime platform will be able to offer sports such as soccer, football, baseball, hockey, and basketball. Over the next few months we will be growing our product to include more sports, and deliver from more API. Potential sports that might be included: UFC, Formula 1, Moto GP and more.

The sport AMM product also has the opportunity to showcase the usage of blockchain technology to one of the biggest industries in the world. The market has reached a maturity point with an opportunity for us to tap into mass adoption. Our goal to gamify DeFi stays the same, Thales keeps building and brings you Overtime, the first decentralized sport AMM.

Method

I found the second contract with the users' Sell reviews, in the topics of which you can find the names of the teams, etc., but I still used the same Json to match the contracts, but you still need Sport IDs. and you have to enter it manually.

Market Resolution

Each market is resolved by Results Data provided by Chainlink Sports Feeds.

Possible Sports Markets resolutions and the effects include:

• HOME WIN - Each holder of HOME WIN tokens can redeem their tokens for $1.00 per token.
