IGP-136: Collect iETHv2 + Liquidity Layer revenue & migrate sUSDai oracles - #170
Merged
Conversation
…oracles Action 1 collects iETHv2 (Lite) stETH revenue and Liquidity Layer revenue for every token with >$5k uncollected (USDC, USDT, ETH, GHO, weETH) into the Fluid Reserve, then forwards the swept balances to Team Multisig. Action 2 migrates the 8 live sUSDai vault oracles (171-173, 175-179) to the newly deployed CappedRateChainlink_SUSDAI oracles and re-points the sUSDai-USDC (DEX 46) and sUSDai-USDT (DEX 48) center prices to the same capped rate (DF nonce 258).

Action 3 pulls 2,400 PST from the Reserve at execution but that funding is out-of-band (mainnet Reserve currently holds 0 PST). Pre-setup now: - reads the Reserve's PST balance on the fork - logs a loud MAINNET ACTION REQUIRED warning on shortfall - tops the Reserve up via tenderly_setErc20Balance so the rebalance simulates against the funded state (USDC leg self-funds via Action 1's 3,400 USDC retention, so no cheat needed there) Cheat verified against a live vnet fork (0 -> 2,400 PST).
ethers.Interface.encodeFunctionData was called statically (TS2339) — the example now builds a proper Interface with the setAdmin fragment.
IGP-136 sim: detect + fund the 2,400 PST Reserve requirement
The Lite stETH revenue will be claimed separately via the rebalancer, outside this payload. Action 1 now only collects the Liquidity Layer revenue (USDC, USDT, ETH, GHO, weETH) into the Reserve and forwards it to Team Multisig, still retaining 3,400 USDC for the Action 3 rebalance. Also trims contract-internal jargon from description.md (revert names, MinMax sentinels, oracle probe details) and updates the sim setup header comment accordingly.
Cuts redundant prose to ~60 lines (matching IGP-130/134 descriptions), folds the standalone Description section into the action sections, and merges the Action 4 tables into one. Expands the truncated oracle and vault addresses to full checksummed form. Drops the PST prerequisite note and the forward-to-Team-Multisig phrase from the title.

Summary
IGP-136 performs three Ethereum actions:

Live gap between current (raw, nonce 248) and new (capped, 258) center price is −0.0084%, so the capped shift-rate completes the transition smoothly within minutes while preserving headroom to track sUSDai yield drift.
