Requirements

Breez provides a Boltz swapId to the user. This swapId needs to be registered with the flash server and listen for updates.

Considerations

1. What information do we want to log? How much data and at what frequency are the writes (and reads)?

• We're mainly interested in high-level transaction details, such as transaction id, timestamp, destination invoices/addresses, swap id, amounts, payment status, etc.

2. What is the retention policy for this data?

6 months min

Design

1. Create a graphql endpoint register a new swap id. Write this to redis
2. Listen to events from Boltz and write new transactions to Mongo. Called name TBD, something like ExternalUserTransactions
