# Locked-Staking

Users can lock COF to obtain veCOF, period from 2 weeks to 4 years. The locked-staking is time-weighted, so longer time locks will be allocated with more distributed veCOF.

1 COF locked for 2 weeks = 0.009589 veCOF

1 COF locked for 1 month = 0.020548 veCOF

1 COF locked for 1 year = 0.25 veCOF

1 COF locked for 4 years = 1 veCOF
