Proposal: Expand Custom Taker Fee on Stable to Stable Trades On Sei v2 - Native USDC

To be posted to Snapshot August 10th, 2025

TL;DR:

A previous proposal was brought up to the Bancor DAO that set a 0.001% (1/10th of a basis point) fee on stable to stable trades for certain trading pair(s) on Sei v2.

This proposal is looking to expand that list with the newly launched Native USDC and possible combinations of Native USDC with other popular stablecoins (USDC.n, kavaUSDT, and USDT0).

Overview:

The default taker fee on Carbon DeFi Sei v2 deployment is 0.4% which means that anyone taking an order from the protocol has to pay this amount. A previous proposal:

was brought up to the Bancor DAO to lower this fee to 0.001% on stable to stable trades for certain trading pairs in order to make Carbon DeFi more competitive with stable to stable swaps that are normally lower across all DEXs.

This list currently encompasses the following trading pairs:

USDC.n / kavaUSDT

USDC.n / USDT0

USDT0 / kavaUSDT

This proposal is seeking to expand the custom taker fee to these other stable pairs.
