## Prerequisites for DOT Deposit
Before starting, ensure you have:
– **DOT Tokens**: Minimum 1 DOT in your wallet

## Frequently Asked Questions (FAQ)

**Q: Can I deposit native Polkadot (DOT) directly?**

**Q: How often is interest paid?**
A: Interest compounds every Ethereum block (~13 seconds), reflected in cDOT token value growth.

**Q: What’s the minimum DOT deposit?**
A: No strict minimum, but consider gas fees. Deposits under 1 DOT may be cost-inefficient.

A: While audited, smart contracts carry risk. Only deposit funds you can afford to lose. Consider decentralized insurance options.

## Conclusion
Depositing DOT on Compound unlocks DeFi earning potential through a straightforward process: bridge DOT to WDOT, connect your wallet, and execute the deposit. While offering attractive yields, always prioritize security through wallet hygiene and contract verification.
