Aerodrome AMM (Classic Pools)

Aerodrome Finance is the largest DEX on Base. This plugin covers the classic AMM module — volatile and stable pools using a Velodrome V2 / Uniswap V2 style constant-product formula. LP tokens are standard ERC-20 tokens (not NFTs).

Key distinction from Aerodrome Slipstream: The classic AMM uses bool stable to identify pool type, not tickSpacing. The router address is different (0xcF77a3Ba... vs 0xBE6D8f0d...).

Architecture: Read-only operations (quote, pools, positions) use direct eth_call via JSON-RPC to https://base-rpc.publicnode.com. Write ops use onchainos wallet contract-call --force after user confirmation.

Pre-flight Checks

# Ensure onchainos CLI is installed and wallet is configured
onchainos wallet addresses

The binary aerodrome-amm must be available in your PATH.

Pool Types

Type	`stable` flag	Formula	Best for
Volatile	`false` (default)	Constant-product x×y=k	WETH/USDC, WETH/AERO
Stable	`true`	Low-slippage curve	USDC/DAI, USDC/USDT

Commands

Write operations require --confirm: Run the command first without --confirm to preview the transaction details. Add --confirm to broadcast.

1. `quote` — Get Swap Quote

Queries Router.getAmountsOut via eth_call (no transaction). Auto-checks both volatile and stable pools unless --stable is specified.

aerodrome-amm quote \
  --token-in WETH \
  --token-out USDC \
  --amount-in 50000000000000

Specify pool type:

aerodrome-amm quote --token-in USDC --token-out DAI --amount-in 1000000 --stable true

Output:

{"ok":true,"tokenIn":"0x4200...","tokenOut":"0x8335...","amountIn":50000000000000,"stable":false,"pool":"0x...","amountOut":118500}

Notes:

Validates pool exists via PoolFactory before calling getAmountsOut
Returns best amountOut across volatile and stable pools
USDC uses 6 decimals, WETH uses 18 decimals

2. `swap` — Swap Tokens

Executes swapExactTokensForTokens on the Aerodrome classic AMM Router. Quotes first, then asks user to confirm before submitting.

aerodrome-amm swap \
  --token-in WETH \
  --token-out USDC \
  --amount-in 50000000000000 \
  --slippage 0.5

With dry run (no broadcast):

aerodrome-amm swap --token-in WETH --token-out USDC --amount-in 50000000000000 --dry-run

Force stable pool:

aerodrome-amm swap --token-in USDC --token-out DAI --amount-in 1000000 --stable true

Output:

{"ok":true,"txHash":"0xabc...","tokenIn":"0x4200...","tokenOut":"0x8335...","amountIn":50000000000000,"stable":false,"amountOutMin":118000}

Flow:

PoolFactory lookup to find best pool (volatile + stable)
Router.getAmountsOut to get expected output
Ask user to confirm token amounts and slippage
Check ERC-20 allowance; approve Router if needed (3-second delay after approve)
Submit wallet contract-call --force to Router (selector 0xcac88ea9)

Important: Max 0.00005 ETH (~0.1 USDC) per test transaction. Recipient is always the connected wallet. Never zero address in live mode.

3. `pools` — Query Pool Info

Lists classic AMM pool addresses and reserves for a token pair.

# Query both volatile and stable pools
aerodrome-amm pools --token-a WETH --token-b USDC

# Query only volatile pool
aerodrome-amm pools --token-a WETH --token-b USDC --stable false

# Query by direct pool address
aerodrome-amm pools --pool 0x...

Output:

{
  "ok": true,
  "tokenA": "0x4200...",
  "tokenB": "0x8335...",
  "pools": [
    {"stable": false, "address": "0x...", "reserve0": "1234567890000000000", "reserve1": "3456789000", "deployed": true},
    {"stable": true, "address": "0x0000...", "deployed": false}
  ]
}

4. `positions` — View LP Positions

Shows ERC-20 LP token balances for common Aerodrome pools or a specific pool.

# Scan common pools for connected wallet
aerodrome-amm positions

# Scan for specific wallet
aerodrome-amm positions --owner 0xYourAddress

# Check specific pool
aerodrome-amm positions --pool 0xPoolAddress

# Check specific token pair
aerodrome-amm positions --token-a WETH --token-b USDC --stable false

Output:

{
  "ok": true,
  "owner": "0x...",
  "positions": [
    {
      "pool": "0x...",
      "token0": "0x4200...",
      "token1": "0x8335...",
      "lpBalance": "1234567890000000",
      "poolSharePct": "0.001234",
      "estimatedToken0": "567890000000",
      "estimatedToken1": "1234000"
    }
  ]
}

Notes:

Scans common pairs (WETH/USDC volatile, WETH/AERO volatile, USDC/DAI stable, etc.) by default
LP tokens are ERC-20, not NFTs — balances are fungible
estimatedToken0/1 based on current pool reserves × LP share

5. `add-liquidity` — Add Liquidity

Adds liquidity to a classic AMM pool (ERC-20 LP tokens). Ask user to confirm before submitting.

aerodrome-amm add-liquidity \
  --token-a WETH \
  --token-b USDC \
  --stable false \
  --amount-a-desired 50000000000000 \
  --amount-b-desired 118000

Auto-quote token B amount:

# Leave --amount-b-desired at 0 to auto-quote
aerodrome-amm add-liquidity \
  --token-a WETH \
  --token-b USDC \
  --stable false \
  --amount-a-desired 50000000000000

Output:

{"ok":true,"txHash":"0xdef...","tokenA":"0x4200...","tokenB":"0x8335...","stable":false,"amountADesired":50000000000000,"amountBDesired":118000}

Flow:

Verify pool exists via PoolFactory
Auto-quote amountB if not provided (Router.quoteAddLiquidity)
Ask user to confirm token amounts and pool type
Approve tokenA → Router if needed (5-second delay)
Approve tokenB → Router if needed (5-second delay)
Submit wallet contract-call --force for addLiquidity (selector 0x5a47ddc3)

6. `remove-liquidity` — Remove Liquidity

Burns LP tokens to withdraw the underlying token pair. Ask user to confirm before submitting.

# Remove all LP tokens for WETH/USDC volatile pool
aerodrome-amm remove-liquidity \
  --token-a WETH \
  --token-b USDC \
  --stable false

# Remove specific LP amount
aerodrome-amm remove-liquidity \
  --token-a WETH \
  --token-b USDC \
  --stable false \
  --liquidity 1000000000000000

Output:

{"ok":true,"txHash":"0x...","pool":"0x...","tokenA":"0x4200...","tokenB":"0x8335...","stable":false,"liquidityRemoved":1000000000000000}

Flow:

Lookup pool address from PoolFactory
Check LP token balance
Ask user to confirm the liquidity amount
Approve LP token → Router if needed (3-second delay)
Submit wallet contract-call --force for removeLiquidity (selector 0x0dede6c4)

7. `claim-rewards` — Claim AERO Gauge Rewards

Claims accumulated AERO emissions from a pool gauge. Ask user to confirm before submitting.

# Claim from WETH/USDC volatile pool gauge
aerodrome-amm claim-rewards \
  --token-a WETH \
  --token-b USDC \
  --stable false

# Claim from known gauge address
aerodrome-amm claim-rewards --gauge 0xGaugeAddress

Output:

{"ok":true,"txHash":"0x...","gauge":"0x...","wallet":"0x...","earnedAero":"1234567890000000000"}

Flow:

Lookup pool address → Voter.gauges(pool) → gauge address
Gauge.earned(wallet) to check pending AERO
If earned = 0, exit early with no-op message
Ask user to confirm the earned amount before claiming
Submit wallet contract-call --force for getReward(wallet) (selector 0xc00007b0)

Notes:

Gauge rewards require LP tokens to be staked in the gauge (separate from just holding LP tokens)
Use --gauge <address> for direct gauge address if pool lookup fails

Error Handling

Error	Likely Cause	Fix
`No valid pool or quote found`	Pool not deployed	Use `pools` to verify; try opposite stable flag
`Pool does not exist for .../stable=...`	Factory returns zero address	Pool not deployed; use existing pool
`No gauge found for pool`	Pool has no gauge	Pool may not have emissions; check Aerodrome UI
`No LP token balance to remove`	No LP tokens held	Add liquidity first or check positions
`onchainos: command not found`	onchainos CLI not installed	Install and configure onchainos CLI
`txHash: "pending"`	Missing `--force` flag	Internal error — should not occur
Swap reverts	Insufficient allowance or amountOutMin too high	Plugin auto-approves; increase slippage tolerance

Skill Routing

For CLMM / concentrated liquidity on Aerodrome, use aerodrome-slipstream instead
For portfolio tracking, use okx-defi-portfolio
For cross-DEX aggregated swaps, use okx-dex-swap
For token price data, use okx-dex-token
