This proposal outlines the upgrade of Dexter smart contracts on the Persistence chain to improve functionality and user experience.

Upgrade Details

The upgrade focuses on four key areas:

1. Improved Stableswap Math:

   • Integrates integer-based calculations for stableswap functions.
   • Enhances handling of smaller inputs and ensures closer alignment with the curve's stableswap math.

2. Spot Price Methods for SKIP Integration:

   • Introduces spot price methods to facilitate integration with the SKIP to power ibc.fun token swaps using Dexter.
   • This integration will be crucial for future functionalities and expansion of the Persistence ecosystem.

3. Simplified Slippage Parameters:

   • Removes unnecessary max-spread checks from the Stableswap function.
   • Streamlines slippage parameter configuration, improving usability for external integrations.

4. Cosmwasm Security Enhancements:

   • Upgrades the underlying Cosmwasm standard library to incorporate the latest security patches.
   • This upgrade strengthens the overall security posture of Dexter smart contracts.

Impact on Existing Pools

This upgrade encompasses a comprehensive overhaul, affecting all existing pools, the router contract, and the vault contract. To ensure a smooth transition, the proposal outlines the following:

• Code Version Updates: Contracts on the current version will be updated to the new version as highlighted below:

Code Name	Existing Code ID	Existing Code Version	New Code ID	New Code Version
Dexter Vault	3	v1.0.0	15	v1.1.0
Dexter Router	6	v1.0.0	16	v1.1.0
Stableswap Pool	8	v1.0.0	18	v1.1.1
Weighted Pool	7	v1.0.0	17	v1.1.1

• Upgrade Process: The upgrade will seamlessly migrate existing pool configurations. It will also ensure that new pools are created with the new code ID.

Contract	Address	New Code ID
Dexter Vault	persistence1k8re7jwz6rnnwrktnejdwkwnncte7ek7gt29gvnl3sdrg9mtnqkstujtpg	15
Dexter Router	persistence132xmxm33vwjlur2pszl4hu9r32lqmqagvunnuc5hq4htps7rr3kqsf4dsk	16
