Low`MAX_WEI_IMPRECISION ` Might Not Be Enough in the Future31Third: BatchTrade Diff · Quantstamp · 12 Jul 2024Fixed

The amount mismatch of around 1 or 2 WEIs originates from a known issue in Lido Finance and possibly other similar protocols (see [Lido Finance issue #442](https://github.com/lidofinance/lido-dao/issues/442)). To address this, the team introduced an error threshold called `MAX_WEI_IMPRECISION` as a constant variable, allowing transfers with a 1 or 2 WEI discrepancy from the expected value. However, this error is anticipated to increase very slowly over time, potentially reaching 5 WEIs in 20 years. If unresolved at the source, the discrepancy could reach 10 WEIs, necessitating a contract update to increase the threshold.
