Use the 'Earn' tab to earn sats by offering liquidity to other market participants. You will be acting as a market maker. Creating a fidelity bond is recommended. In Jam, takers pay 100% of the mining fees: as a market maker, you will not pay anything. Just profit!

Fidelity Bonds

Make sure to create a fidelity bond to increase the chances of your offer being taken.

A fidelity bond is a mechanism which ensures that market actors act honestly. It is a protection mechanism against Sybil attacks. A fidelity bond makes the creation of cryptographic identities costly.

Fidelity bonds improve the privacy guarantees of the whole system and increase your chance of being chosen as a market maker drastically.

Be aware that funds locked in a Fidelity Bond will not be included in your offer amount, so remember to keep additional funds in order to participate as a market maker.


It is impossible to move or spend funds that are locked in a fidelity bond before the bond expires. They cannot be used in collaborative transactions (neither as taker nor as maker) as fidelity bonds are time-locked by the Bitcoin protocol.
