BOB SDK: Alpha launch

[nud3l]

Abstract

The BOB SDK is meant as a set of Solidity contracts, Rust and/or TypeScript functions, and UI components to access the unique functions of BOB and make developing new applications on BOB simple.

Motivation

BOB combines Bitcoin and EVM functionality into a coherent SDK to give anyone access to Bitcoin data, verification functions, account abstraction, and more. The SDK should it make easy for anyone to access to the BOB functionality.

Specification

BTC Relay and Libs

• Builders MUST be able to interact with the BTC relay contracts (documentation, Solidity libraries for Bitcoin types, ...)
• Builders MUST be able to verify transaction inclusion with the BTC relay, have an example implementation, and documentation to understand how it works
• Builders MUST be able to verify the inclusion of an ordinal, have an example implementation, and documentation
• Builders MUST be able to verify BRC20 deploy, mint, and transfer operations, have an example implementation, and documentation

Dev Tooling

• Builders MUST be able to use foundry to develop and deploy contracts on the rollup, see also feat: Optimism execution changes bluealloy/revm#682
• Builders MUST be able to use remix to develop and deploy contracts on the rollup

UX Tooling

• Builders MUST be able to allow users paying fees in a bridged BTC deployed as an ERC20. Recommended is to use OpenGSN https://github.com/opengsn/gsn to achieve this with a deployment of OpenGSN for BOB.
• Builders MUST have an easy way to integrate OpenGSN into their contracts

@nud3l for the task of documenting deploying contracts with remix, should we include verifying and publishing the contract on the chain explorer?

[nud3l]

Adding how to verify the contracts would be good to add to the docs in a new subsection after this one: https://docs.gobob.xyz/docs/build/getting-started/helloworld#interact-with-the-coin-contract @danielsimao :
