Hello all, welcome to the Vest DeFi Research Forum! This is intended to be an inclusive place for general research into decentralized finance. Anyone can publish posts open to the community for discussion. This could be… --- ## [\[RFC\] Consume the Givens: Atomic Cross-Shard Counter Updates](https://research.vest.xyz/t/rfc-consume-the-givens-atomic-cross-shard-counter-updates/217)
**Author:** [@Elliottdehn](https://research.vest.xyz/u/Elliottdehn)\ **Replies:** 1\ **Last updated:** [May 15, 2024, 7:22pm UTC](https://research.vest.xyz/t/rfc-consume-the-givens-atomic-cross-shard-counter-updates/217 "2024-05-15T19:22:11Z")
Situation I’d consider the “effectiveness” of this system to be the minimal number of market orders we can process per-market, per-second. The slowest market (or the stopped market) determines this number. The risk engi… --- ## [zkRisk](https://research.vest.xyz/t/zkrisk/205)

Abstract We present a novel framework to unify the trading experience of digital assets and the money market such that the solvency of an exchange is guaranteed with … --- ## [vAMMs and Virtual Liquidity Curve](https://research.vest.xyz/t/vamms-and-virtual-liquidity-curve/204)
**Author:** [@Perpv2](https://research.vest.xyz/u/Perpv2)\ **Replies:** 0\ **Last updated:** [July 13, 2023, 6:05pm UTC](https://research.vest.xyz/t/vamms-and-virtual-liquidity-curve/204 "2023-07-13T18:05:43Z")
Motivation After seeing many protocols fail with vanilla vAMMs, it’s easy to conflate good vAMM with bad vAMM. However, vAMM can be a powerful tool with a properly built-in risk engine. Here, we explore how a pricing sch… --- ## [Optimal Liquidations via Convex Optimization](https://research.vest.xyz/t/optimal-liquidations-via-convex-optimization/201)
**Author:** [@max](https://research.vest.xyz/u/max)\ **Replies:** 2\ **Last updated:** [May 5, 2023, 8:33pm UTC](https://research.vest.xyz/t/optimal-liquidations-via-convex-optimization/201 "2023-05-05T20:33:31Z")
TLDR We propose a convex optimization approach for determining the optimal liquidation order in cross-margined AMM-based exchanges, minimizing the negative impact on exchange solvency. Motivation Liquidation is crucial … --- ## [Multivariate Volatility Forecasting for Risk-Indifference Pricing](https://research.vest.xyz/t/multivariate-volatility-forecasting-for-risk-indifference-pricing/195)
**Author:** [@Rem](https://research.vest.xyz/u/Rem)\ **Replies:** 2\ **Last updated:** [April 6, 2023, 5:44pm UTC](https://research.vest.xyz/t/multivariate-volatility-forecasting-for-risk-indifference-pricing/195 "2023-04-06T17:44:22Z")
TLDR We explore multiple methods for forecasting multivariate volatility which is then used to determine risk indifference price for perp positions. While DCC-GARCH performs well in short-term forecast, GO-GARCH with red… --- ## [New Framework for Funding Rates](https://research.vest.xyz/t/new-framework-for-funding-rates/34)
**Author:** [@max](https://research.vest.xyz/u/max)\ **Replies:** 8\ **Last updated:** [January 30, 2023, 10:49pm UTC](https://research.vest.xyz/t/new-framework-for-funding-rates/34 "2023-01-30T22:49:06Z")
TLDR We design a new funding rate mechanism for an AMM-based exchange that compensates the exchange for the risk of long-short imbalance and can be extended to adapt to arbitrage demand. See the full write-up here. Moti… --- ## [Utility Indifference Pricing Overview](https://research.vest.xyz/t/utility-indifference-pricing-overview/25)
**Author:** [@max](https://research.vest.xyz/u/max)\ **Replies:** 6\ **Last updated:** [November 4, 2022, 6:10pm UTC](https://research.vest.xyz/t/utility-indifference-pricing-overview/25 "2022-11-04T18:10:51Z")
TLDR Inspired by Chen and Pennock’s constant utility market maker framework, we explore exponential utility indifference pricing for long-tail perpetual derivatives but found this pricing not robust. Are there robust alt… --- ## [Optimal Margin Requirements](https://research.vest.xyz/t/optimal-margin-requirements/31)

TLDR We construct an optimization problem to set optimal margin requirements based on expectiles to balance between prudentiality and opportunity cost. See the full write-up here. Motivation We aim to build an exchange … --- ## [Bandit Funding Rates](https://research.vest.xyz/t/bandit-funding-rates/39)
**Author:** [@rick](https://research.vest.xyz/u/rick)\ **Replies:** 5\ **Last updated:** [January 2, 2023, 5:44pm UTC](https://research.vest.xyz/t/bandit-funding-rates/39 "2023-01-02T17:44:14Z")
TLDR We formalize choosing funding rates as an adversarial bandit problem and run Monte Carlo simulations using agent-based model to find the bandit algorithm with optimal performance. See the full write-up and appendix h…
