| description | Interact with DeFi protocols on MAINNET via the ChainGPT plugin. Aave V3 (supply/borrow/repay/withdraw + health-factor monitoring across 7 chains), Lido stETH staking, EigenLayer restaking. Yield discovery: Pendle yield-trading markets (PT/YT), Morpho Blue lending markets + MetaMorpho vaults. Custody-free — plugin builds unsigned tx, user signs externally. Mandatory pre-flight: check Aave health factor before any borrow or withdraw; verify approval state before any supply/repay/deposit. Triggers: aave, lido, stake eth, steth, restake, eigenlayer, supply, borrow, repay, withdraw, lending, health factor, liquidation, leverage, yield, defi position, pendle, morpho, gauntlet, fixed yield, pt, yt, metamorpho, vault, lending market. |
ChainGPT DeFi Skill
You manage real DeFi positions on mainnet. The plugin is custody-free — it returns unsigned transactions; the user signs externally via MetaMask, Rabby, hardware wallet, ERC-4337 smart account, or WalletConnect.
Protocols supported
| Protocol | What | Chains |
|---|
| Aave V3 | Lending market (supply / borrow / repay / withdraw + health) | ethereum, base, arbitrum, optimism, polygon, bsc, avalanche |
| Lido | stETH liquid staking | Ethereum mainnet |
| EigenLayer | Restake LSTs (stETH / rETH / cbETH / …) | Ethereum mainnet |
| Pendle (read) | Yield-trading markets — split assets into PT (fixed) + YT (floating) | ethereum, arbitrum, optimism, bsc, base, mantle |
| Morpho Blue (read) | Isolated lending markets + MetaMorpho curated vaults | ethereum, base |
Hard rules for mainnet
- Before borrowing or withdrawing from Aave, ALWAYS call
chaingpt_defi_aave_health and surface the health factor. Borrowing or withdrawing collateral lowers HF; if it drops below 1.0 the position is liquidated. Refuse the action and tell the user to top up if HF would drop below 1.2 after the requested operation.
- Before supplying, repaying, or depositing, verify the user has approved the pool / strategy manager. ERC-20 approval is a separate signed transaction. Use
chaingpt_dex_approve_tx token=<asset> spender=<aave-pool-or-strategy-manager> acknowledgeMainnet=true first if not done (the ack gate applies to approvals too).
- Echo the USD-equivalent values before asking for confirmation. Pull the asset price from
chaingpt_research_token if not obvious.
- For Lido stake, note that stETH rebases — the balance grows daily. Don't store the staked amount as the "stETH balance"; it will diverge.
- For EigenLayer, note the 7-day withdrawal queue. Deposits are functionally illiquid for a week. Surface this fact before asking for confirmation.
The "supply on Aave" pipeline
chaingpt_research_token # confirm the asset (price, contract)
chaingpt_defi_aave_health # current position state (if any)
chaingpt_dex_approve_tx # approve the Aave Pool to spend the asset (acknowledgeMainnet=true)
spender=<AAVE_POOL_ADDRESS> # surface this from the build_tx output
chaingpt_defi_aave_supply_tx # REFUSES mainnet unless acknowledgeMainnet=true

chaingpt_defi_aave_health # confirm the supply landed in the position
The "borrow on Aave" pipeline
chaingpt_defi_aave_health # MANDATORY — check headroom + HF
chaingpt_research_token # confirm the asset to borrow
chaingpt_defi_aave_borrow_tx # requires acknowledgeMainnet=true

Surface the post-borrow estimated health factor before asking for confirmation. Rough math: post-HF ≈ totalCollateralUsd × liquidationThreshold% / (totalDebtUsd + newBorrowUsd).
The "stake ETH on Lido" pipeline
chaingpt_research_token symbol="ETH" # current price for USD context
chaingpt_defi_lido_stake_tx amountEth="X" from="0x…" # requires acknowledgeMainnet
[user signs + broadcasts]
stETH is liquid (you can swap it back to ETH via Curve / Uniswap / 1inch any time at a small discount), unlike native staking.
The "restake on EigenLayer" pipeline
[user has stETH or another supported LST]
chaingpt_dex_approve_tx # approve EigenLayer StrategyManager to pull the LST (acknowledgeMainnet=true)
spender="0x858646372CC42E1A627fcE94aa7A7033e7CF075A"
chaingpt_defi_eigenlayer_deposit_tx # requires acknowledgeMainnet
[user signs + broadcasts]
Common strategy addresses:
- stETH:
0x93c4b944D05dfe6df7645A86cd2206016c51564D
- rETH:
0x1BeE69b7dFFfA4E2d53C2a2Df135C388AD25dCD2
- cbETH:
0x54945180dB7943c0ed0FEE7EdaB2Bd24620256bc
Remember: 7-day exit queue. Don't restake more than you can afford to be illiquid for a week.
Credit accounting
DeFi reads + tx-builds burn 0 ChainGPT credits. The funnel into credits comes from the upstream chaingpt_research_token / chaingpt_news_fetch / chaingpt_audit_contract calls the user makes before deciding to act.
What this skill does NOT do
- Custody anything. The plugin never sees a private key.
- Liquidation protection or auto-deleveraging. Use a dedicated keeper service if you need automation.
- Yield optimization across protocols. The user picks the strategy; this skill executes it.
- Build Pendle PT/YT swap or Morpho supply/borrow transactions. Both protocols use complex multicall + permit2 patterns; the read tools here surface markets so the user can pick a target, then deploy via the official frontend (https://app.pendle.finance / https://app.morpho.org).
- Curve, Convex, ether.fi — deferred for future tools.
