LP Remove — Collect Fees + Decrease Liquidity

Two-step process to exit a Uniswap v3 position:

collect — harvest accrued fees (WETH + DIEM) to agent wallet
decreaseLiquidity — burn liquidity and unlock token principal

Both calls go to the NFPM at 0x03a520b32C04BF3bEEf7BEb72E919cf822Ed34f1.

Read position state first

cast call 0x03a520b32C04BF3bEEf7BEb72E919cf822Ed34f1 \

Step 1: Collect accrued fees

// NFPM.collect(CollectParams)
struct CollectParams {
  uint256 tokenId;
  address recipient;
  uint128 amount0Max;  // use type(uint128).max to collect all
  uint128 amount1Max;  // use type(uint128).max to collect all

  --private-key $AGENT_PRIVATE_KEY \
  --rpc-url https://mainnet.base.org

Step 2: Decrease liquidity (full exit)

struct DecreaseLiquidityParams {
  uint256 tokenId;
  uint128 liquidity;   // from positions() call above
  uint256 amount0Min;  // slippage floor
  uint256 amount1Min;  // slippage floor
  uint256 deadline;
}

# Full liquidity removal — set liquidity to value from positions() call
cast send 0x03a520b32C04BF3bEEf7BEb72E919cf822Ed34f1 \
  "decreaseLiquidity((uint256,uint128,uint256,uint256,uint256))(uint256,uint256)" \
  "(<TOKEN_ID>,<LIQUIDITY>,0,0,<DEADLINE>)" \
  --private-key $AGENT_PRIVATE_KEY \
  --rpc-url https://mainnet.base.org

# Then collect again to pull the unlocked principal
cast send 0x03a520b32C04BF3bEEf7BEb72E919cf822Ed34f1 \
  "collect((uint256,address,uint128,uint128))(uint256,uint256)" \

  --private-key $AGENT_PRIVATE_KEY \
  --rpc-url https://mainnet.base.org

Code path (not yet implemented)

Add collectFromLP and removeFromLP to harness/providers/liquidity.ts using the same TxSender + publicClient pattern as reinvestToLP. Read tokenId from memory/lp-positions.jsonl.

Notes

Always collect fees before decreaseLiquidity — fees are tracked separately.
After full exit, the NFT can be burned via NFPM.burn(tokenId) to reclaim gas.
If the position is out of range (tickUpper < currentTick for DIEM-only), principal is 100% DIEM.
amount1Min = 0 is acceptable for a DIEM-only out-of-range position (no price risk).
