staticCall and gasLimit

[reuptaken]

I'm trying to use staticCall method on Uniswap v3 NonfungiblePositionManager contract decreaseLiquidity method and I'm getting UNPREDICTABLE_GAS_LIMIT error even if I set gasLimit manually… why is that?

 positionManager.callStatic.decreaseLiquidity({
  tokenId: tokenIdHexString,
  liquidity: MAX_UINT128,
  amount0Min: MAX_UINT128,
  amount1Min: MAX_UINT128,
  deadline: MAX_UINT256
},
{
  from: owner,
  gasPrice: '1',
  gasLimit: '1000000000000000000'
} 
).then((results) => {
  console.log(results)
  process.exit(0)
})

Your gas limit may be too high. I think most nodes only allow a gas limit for calls to be up to twice the block gas limit, and that looks a LOT bigger.

When not setting you may be getting the error due to the method reverting. Does the from account (owner) have permissions to call decreaseLiquidity? I’m not familiar with the uniswap contract code, but I would recommend checking out the contract source to see what restrictions the contract is imposing.

@reuptaken You're passing max value in liquidity parameter. That likely causes this require statement to fail.

Hey, thanks for that. I'm doing it for purpose (but maybe I'm wrong). Eg. when checking how much fees are accrued on account, Uniswap interface calls static similar method (collect) with max amounts, and method returns how much it would return if this wasn't a staticCall. But maybe decreaseLiquidity is different… niedz., 30 maj 2021 o 12:07 soham ***@***.***> napisał(a):
