The Lightning Network Liquid The Bitcoin Blockchain

eCash is digital cash built on top of Bitcoin. With the Cashu protocol, you can send and receive bitcoin instantly, almost for free, and with full privacy — just like physical cash, but in digital form. Tokens live on your device, and no one can trace your transactions.

How does eCash work?

Deposit bitcoin – You send bitcoin (typically via Lightning) to a mint.

Receive eCash tokens – The mint issues tokens using "blind signatures". This means the mint can't see who owns which tokens.

Use your tokens – Send them to others, pay for services, or redeem them back to bitcoin. Transactions are instant and almost free.

Benefits and limitations

Benefits

Privacy – The mint can't see your balance, your transactions, or who you trade with.

Speed – Transactions are instant, since they don't require confirmation on the blockchain.

Low fees – Almost free to send and receive.

Easy onboarding – Perfect for small amounts, tips, and micropayments.

Limitations

Trust in the mint – Your bitcoin is held by the mint. Use several mints to spread the risk.

Not for large amounts – Designed for everyday transactions, not long-term storage.

Device-dependent – Tokens live on your device, but Cashu has a recovery feature with a seed phrase.
