Protocol Description

• GYD is a USD denominated meta-stablecoin, issued by Gyroscope.
• USDC.e is the bridged version of a USD denominated stablecoin, issued by Circle. aUSDC.e is the yield-bearing deposit receipt token for lending out USDC.e on Aave, in a static wrapper.
• sDAI is a USD denominated stablecoin, issued by MakerDAO, staked to earn yield.

Motivation

GYD is launching on Gnosis Chain. These are two core pools to enable initial liquidity.

Specification

1. Governance: The Gyroscope Protocol will be governed by a DAO and relevant stakeholder with the full launch on Ethereum. For now, the FTL Labs multi-sig can pause the pool, change the swap fee and set the protocol fee. As a custom pool by Gyroscope, the E-CLP will be controlled by Gyroscope governance upon its launch.

2. Oracles:

• GYD/aUSDC.e
  • ‘rateProvider0’: 0x00
  • ‘rateProvider1’: 0x5F62fd24941B585b91EB059E0ea1a7e729357511 (and relevant review)
• GYD/sDAI

  • ‘rateProvider0’: 0x89C80A4540A00b5270347E02e2E144c71da2EceD (and relevant review)

  • ‘rateProvider1’: 0x00

3. Audits: Audit reports by Nethermind, Trail of Bits, and Runtime Verification can be accessed here (the E-CLP is called the “CEMM” in these reports). In addition, the E-CLP code has been live in production since November 2022.

4. Centralization vectors: No centralization vectors. The FTL Labs team’s multi-sig can - currently - pause the pool, change the swap fee and set the protocol fee.

5. Market History: These are the first GYD pools on Gnosis Chain.

6. Value: This pool is intended to better match the historic prices and low volatility of the included tokens.

Specification

Transaction: The Balancer Maxi LM Multisig eth:0xc38c5f97B34E175FFd35407fc91a937300E33860 will interact with the GaugeAdderv4 at 0x5DbAd78818D4c8958EfF2d5b95b28385A22113Cd and call the addGauge function twice with the following arguments:

gauge(address): 0xFa2F6BE7cF4da6FaE6A011A4EFC53180c9Cf0a1b gaugeType(string): Gnosis

gauge(address): 0xe2251F5cc98f8Ccd8812Be9c0aAe8A9bD29500F3 gaugeType(string): Gnosis
