== OceanDynamo As one important use case for OceanDynamo is to facilitate the conversion of SQL databases to no-SQL DynamoDB databases, it is important that the syntax and semantics of OceanDynamo are as close as possible to those of ActiveRecord. This includes callbacks, exceptions and method chaining semantics. OceanDynamo follows this pattern closely and is of course based on ActiveModel. The attribute and persistence layer of OceanDynamo is modeled on that of ActiveRecord: there's +save+, +save!+, +create+, +update+, +update!+, +update_attributes+, +find_each+, +destroy_all+, +delete_all+, +read_attribute+, +write_attribute+ and all the other methods you're used to. The design goal is always to implement as much of the ActiveRecord interface as possible, without compromising scalability. This makes the task of switching from SQL to no-SQL much easier. OceanDynamo uses only primary indices to retrieve related table items and collections, which means it will scale without limits. OceanDynamo is fully usable as an ActiveModel and can be used by Rails controllers. Thanks to its structural similarity to ActiveRecord, OceanDynamo works with FactoryBot.

Add Bitcoin Lightning checkout to your Rails app and receive payments directly into a wallet you control. Mount the engine, connect a receive-only Nostr Wallet Connect (NWC) wallet, and wire up three hooks for authorization, order amounts, and fulfillment. Optional swaps let customers pay with USDT, USDC, SOL, and ETH through a configured provider; you receive BTC over Lightning in your wallet. Available assets and networks depend on the provider. OpenReceive handles invoices, payment attempts, and settlement reconciliation using your existing application database. Keep your orders, users, prices, and fulfillment in your app, with no separate OpenReceive database, Redis, or payment service to deploy. Includes an install generator, PostgreSQL, SQLite, and MySQL support, plus an optional wallet-notifications worker.
