Hydra for payments

Hydra heads can support repeated payments between a fixed set of operators. Users can deposit funds while a head is open, transact on L2, and return funds to L1 through decommits or final settlement.

The articles in this section describe application designs and earlier integration work. They are not compatibility guarantees for a particular Hydra release. Before adopting an external SDK, check its supported node version, deposit lifecycle, API events, and recovery behavior.

Earlier tooling​

The Hydra for payments project explored payment-channel APIs and wallet integration. Its 2022 introduction provides historical context; consult the project's current repository for maintenance and compatibility information.

A payment service connects client wallets to Hydra infrastructure.

For an example maintained in this repository, see the delegated demo.
