A primer on perpetuals

no code implementations7 Sep 2022 Guillermo Angeris, Tarun Chitra, Alex Evans, Matthew Lorig

When asset prices can jump and the volatility process is independent of the underlying risky assets, we derive an explicit replication strategy for the short side of a perpetual contract.

Replicating Monotonic Payoffs Without Oracles

no code implementations26 Nov 2021 Guillermo Angeris, Alex Evans, Tarun Chitra

In this paper, we show that any monotonic payoff can be replicated using only liquidity provider shares in constant function market makers (CFMMs), without the need for additional collateral or oracles.

Optimal Fees for Geometric Mean Market Makers

no code implementations1 Apr 2021 Alex Evans, Guillermo Angeris, Tarun Chitra

Trading fees have been proposed as a mechanism for compensating LPs for arbitrage losses.

Replicating Market Makers

no code implementations26 Mar 2021 Guillermo Angeris, Alex Evans, Tarun Chitra

We present a method for constructing Constant Function Market Makers (CFMMs) whose portfolio value functions match a desired payoff.

When does the tail wag the dog? Curvature and market making

no code implementations15 Dec 2020 Guillermo Angeris, Alex Evans, Tarun Chitra

We show that this definition is tightly related to the curvature of a CFMM's trading function and can be used to explain a number of heuristic results.

Why Stake When You Can Borrow?

no code implementations16 Jun 2020 Tarun Chitra, Alex Evans

As smart contract platforms autonomously manage billions of dollars of capital, quantifying the portfolio risk that investors engender in these systems is increasingly important.

Improved Price Oracles: Constant Function Market Makers

no code implementations22 Mar 2020 Guillermo Angeris, Tarun Chitra

Automated market makers, first popularized by Hanson's logarithmic market scoring rule (or LMSR) for prediction markets, have become important building blocks, called 'primitives,' for decentralized finance.

Competitive equilibria between staking and on-chain lending

no code implementations28 Nov 2019 Tarun Chitra

Proof of Stake (PoS) is a burgeoning Sybil resistance mechanism that aims to have a digital asset ("token") serve as security collateral in crypto networks.

An analysis of Uniswap markets

no code implementations8 Nov 2019 Guillermo Angeris, Hsien-Tang Kao, Rei Chiang, Charlie Noyes, Tarun Chitra

Uniswap -- and other constant product markets -- appear to work well in practice despite their simplicity.

Committee Selection is More Similar Than You Think: Evidence from Avalanche and Stellar

no code implementations7 Apr 2019 Tarun Chitra, Uthsav Chitra

Increased interest in scalable and high-throughput blockchains has led to an explosion in the number of committee selection methods in the literature.
