Summary
This proposal:
- Raises the USDai ecosystem from dust limits (IGP-133) to launch limits on DEXes 46 and 48 and vaults 171–173 and 175–179, removing Team Multisig auth on each.
- Holds the USDai-USDC market (DEX 47 + vault 180) until a later launch — vault 180 gets borrow dust limits and Team Multisig auth is retained on both (DEX 47 launch limits ship together with the vault).
- Deprecates the T1 vault 174 (USDai / USDC).
- Sends
148 stETH of accrued iETHv2 (Lite) revenue from the Reserve to Team Multisig.
Governance sets limits and auth only; per-market config (CF, LT, etc.) is applied by Team Multisig.
Code Changes
Action 1: USDai Ecosystem Launch Limits + Remove Team Multisig Auth
USDai (0x0A1a1A107E45b7Ced86833863f482BC5f4ed82EF), sUSDai (0x0B2b2B2076d95dda7817e785989fE353fe955ef9). Ids verified against the live Fluid DEX_FACTORY / VAULT_FACTORY.
| Market | Id | Type | Limits |
|---|
| sUSDai-USDC DEX | 46 | smart col | $10M per token |
| sUSDai-USDT DEX | 48 | smart col | $10M per token |
| sUSDai / USDC | 171 | TYPE_1 | $8M / $8M / $15M withdraw / base borrow / max borrow |
| sUSDai / USDT | 172 | TYPE_1 | $8M / $8M / $15M |
| sUSDai / GHO | 179 | TYPE_1 | $8M / $8M / $15M |
| sUSDai / USDC-USDT | 173 | TYPE_3 | $8M supply; USDC-USDT DEX (id 2) borrow shares 3.6M / 6.75M |
| sUSDai-USDC / USDC-USDT | 175 | TYPE_4 | smart col at DEX 46; USDC-USDT DEX (id 2) borrow shares 3.6M / 9M |
| sUSDai-USDT / USDC-USDT | 176 | TYPE_4 | smart col at DEX 48; USDC-USDT DEX (id 2) borrow shares 3.6M / 9M |
| sUSDai-USDT / USDT | 177 | TYPE_2 | USDT debt $8M / $20M; smart col at DEX 48 |
| sUSDai-USDC / USDC | 178 | TYPE_2 | USDC debt $8M / $20M; smart col at DEX 46 |
Team Multisig auth is removed on every market above. USDC-USDT DEX (id 2) borrow shares are denominated in 1e18 shares (~$2.20/share).
Action 2: Hold USDai-USDC Market (DEX 47 + Vault 180)
DEX 47 is used only by the T2 vault 180, so both launch together in a later IGP. Team Multisig auth is retained on both; vault 180 gets borrow dust limits ($7k / $9k), and DEX 47 limits are left unchanged.
Action 3: Deprecate Vault 174
Vault 174 (USDai / USDC, TYPE_1) is superseded by vault 180: limits restricted, user operations paused, Team Multisig auth removed.
Action 4: Send 148 stETH of iETHv2 (Lite) Revenue
Send 148 stETH of accrued Lite revenue from the Fluid Reserve to Team Multisig via FLUID_RESERVE.withdrawFunds. The revenue is collected into the Reserve separately by Team Multisig, so the payload performs no on-chain claim.
Conclusion
IGP-134 raises the USDai ecosystem (DEXes 46 and 48, vaults 171–173 and 175–179) to launch limits, holds the USDai-USDC market (DEX 47 + vault 180) until its later launch, deprecates vault 174, and sends 148 stETH of iETHv2 Lite revenue from the Reserve to Team Multisig.
