Keeping a hawl on a wallet that never sits still

The hawl is the lunar year that has to pass before zakat is due. The common worry is that swapping tokens restarts it — that a wallet trading weekly can never complete one. It does not work that way.

The clock is on the wealth, not the asset

The hawl begins the day your zakatable wealth first crosses the nisab, and it continues as long as it stays above. Selling SOL for USDC changes the shape of the wealth, not its existence. Only dropping below the nisab breaks the year and resets the clock.

So an active trader and a dormant holder who both stayed above the threshold owe on the same date. The only figure that matters from the whole year is the valuation on the day it closes.

Fixing the date

Pick your anniversary in the Hijri calendar and it will hold. A lunar year is about eleven days shorter than a solar one, so a Gregorian date drifts backwards through the seasons and, roughly every thirty-three years, quietly skips a year of zakat entirely.

• Set the anniversary once and keep it, even if the wallet changes hands or chains.
• Record the valuation on the day, not from memory a month later.
• If you fall below the nisab mid-year, note the date — that is what restarts the clock.
