I mistakenly locked up my pi coins for 3 years, is there any way to undo it?

Unfortunately, once Pi Coins are locked in the Pi Network app, the lockup period is irreversible. The Pi Network explicitly designs the lockup feature as a binding commitment to contribute to the ecosystem's stability and growth, so there is no way to undo or modify the lockup duration once it's set.

Here’s what you can do moving forward:

1. Contact Pi Support: If you believe this was a genuine mistake, you can try reaching out to the Pi Network's support team through the app. While they are unlikely to reverse a lockup, they may offer guidance or confirm the lockup's terms.

2. Understand Future Lockups: Use this experience as a learning moment to double-check all parameters before confirming any future lockup plans.

3. Focus on Ecosystem Participation: Even with your Pi locked, you can still contribute to the network by mining, verifying, and engaging with the ecosystem. Your locked Pi will eventually become accessible at the end of the lockup period.
