You setup a btcpay server account, forgot to setup SMTP (or set it up wrong) and then forgot your password. Now you can't get back in. Here's how I recovered from this situation:

1. Create a new user according to these instructions. But this isn't enough because (1) Your new user isn't a member of any stores and (2) for me at least this new user couldn't setup SMTP ...

2. There is a postgres table called UserStore which tracks membership of users in stores. When you execute the following command in postgres

select * from "UserStore";

First, update your old BTCPayServer to the newest version. This way there aren't any database schema conflicts with the your server.

SSH to old server you are migrating from. Create a dump of the your database's schema and data

docker exec generated_postgres_1 pg_dumpall -c -U postgres > backup.sql

Try opening that backup.sql file in your text editor of choice. You will see it's just a series of SQL statements which:

/// To use this demo:
/// - create a 3 node network in polar (https://lightningpolar.com/) -- Alice, Bob and Carol
/// - Create channels between Alice and Carol, and between Alice and Bob.
/// - Create an invoice from Carol. Use the `decodepayreq` and `lookupinvoice` lncli commands to get preimage associated with Carol's invoice
/// - Run this program with Alice's LND credentials, and the preimage from step above. For instance:
///   `cargo run --example subscribe_htlcs 127.0.0.1 10003 /Users/justin/.polar/networks/2/volumes/lnd/alice/tls.cert /Users/justin/.polar/networks/2/volumes/lnd/alice/data/chain/bitcoin/regtest/admin.macaroon <preimage>`
/// - Have Bob pay the invoice via Polar UI
/// - This program should output HTLC information. Polar should print success message.

setting up developer environment

Instructions.

Our developer environment is amazing, but it downloads a few gigabytes of data to get set up

About Minimint

Minimint is similar to Liquid. But instead of 1 monolithic codebase, it is very modular. So it's more like a "framework for building federations". One module implements "Chaumian ecash", another integrates with Lightning, another is an on-chain wallet.

The on-chain wallet module currently has a public descriptor like this: wsh(sortedmulti(3,02b5b951e6426bc30ba6e7e1cb9cfae06c2658c043614c0fa37a7c4a649a4a3056,026ad269307053e5a11f7ab73209e89791ae31cabfa00b5fa2811bb25633eec6d6,034c71c3f3c2a8ecf07477158be4d9f37b44694b2987f6487c3884857002348fd1,033d94f61ac8bd8fc460a91f7b61e45a16b51d10097200f17fb0998a7483cc8f19))#cc9uhqy3. Each federation server controls one of these keys. When a user deposits into the federation, they

(1) Tweak each pubkey in this descriptor with some random number X.

(2) Deposit to this address associated with this tweaked

How To Start A Startup by Paul Graham

(original is here, hosting in gist so that I can link to specific section)

You need three things to create a successful startup: to start with good people, to make something customers actually want, and to spend as little money as possible. Most startups that fail do it because they fail at one of these. A startup that does all three will probably succeed.

And that's kind of exciting, when you think about it, because all three are doable. Hard, but doable. And since a startup that succeeds ordinarily makes its founders rich, that implies getting rich is doable too. Hard, but doable.

If there is one message I'd like to get across about startups, that's it. There is no magically difficult step that requires brilliance to solve.
