fedimint-http: A Fedimint HTTP Client (and Cashu Proxy)
fedimint-http exposes a REST API to interact with the Fedimint client.
Set the variables in .env
by copying example.env
, then run cargo run
. It's also set up as a clap app so you can start the server with command line args as well.
Fedimint Client Endpoints
The Fedimint client supports the following endpoints (and has naive websocket support at /fedimint/v2/ws
, see code for details until I improve the interface. PRs welcome!)
Admin related commands:
/fedimint/v2/admin/info
: Display wallet info (holdings, tiers)./fedimint/v2/admin/backup
: Upload the (encrypted) snapshot of mint notes to federation./fedimint/v2/admin/discover-version
: Discover the common api version to use to communicate with the federation./fedimint/v2/admin/restore

Soon(TM): maps Cashu NUT endpoints to fedimint client.
Supported Cashu NUTs: (Notation, Utilization, and Terminology)
- NUT-00: Notation, Utilization, and Terminology
- Fedimint ecash does not currently encode the federation endpoint as part of the ecash, just the federation id. Fedimint encourages longer running relationships based off its trust model so doesnt currently support on the fly issuance / reissuance. Can coerce a mapping but doesnt exactly match. returns a federation id instead
- NUT-01: Mint public key exchange
-
/v1/keys
: supportable -
/v1/keys/{keyset-id}
: supportable (fedimint only maintains 1 keyset) - Fedimint does not currently rotate keysets. Responds with single keyset mapping in Cashu format.
-
- NUT-02: Keysets and keyset ID
-
/v1/keysets
: supportable
-
- NUT-03: Swap tokens
-
/v1/swap
: supportable - Equivalent to Fedimint Reissue. Proofs are slightly different but functionally equivalent.
-
- NUT-04: Mint tokens
-
/v1/mint/quote/{method}
: supportable- method=bolt11: supportable via lngateway
- method=onchain: supportable via pegin
-
/v1/mint/quote/{method}/{quote_id}
: supportable -
/v1/mint/{method}
: supportable- Fedimint client handles these a little differently but can probably coerce the flow, dont get why it requires the 2nd round after status is completed, should just return the notes there.
-
- NUT-05: Melting tokens
-
/v1/melt/quote/{method}
: supportable- method=bolt11: supportable via lngateway
- method=onchain: supportable via pegout
