I. Introduction

Blue Terra is a decentralized protocol for the global democratization of stable and accessible property rights.

Toward this end, we believe in the power of sharing some of the secret sauce that makes Blue Terra possible so that others may build and expand on the core model.

This repo contains the source code for the Blue Terra Civic KYC nonce Solana program.

II. Requirements

1. Rustup
2. Solana
3. Anchor

III. Program IDL

IV. Program Overview

The following is a high level description of the Anchor Program used in our claim land and KYC process.

The program is a minimalist nonce written in Anchor Lang and provides Blue Terra a simple way to keep track of KYC verified wallets and civic tokens on-chain.

In particular, if a Blue Terra NFT holder has a valid KYC, through the posession of a valid civic gatewayToken SPL token, then they will be able to interact with the kyc-program to claim their land and activate the leases embedded within their NFTs.

The program contains one instruction, claimLand. This instruction leverages the Civic Gateway decorator to detect the KYC status of a given walletAddress and gatewayToken.

On detection of a valid Civic KYC status, the program will log the walletAddress and gatewayToken of the user to the program standard output.

V. Building

To build this program run:

anchor build 

On successful build you will have a target directory in your top level.

VI. Deployment

To deploy the program follow the steps below:

Find the program's address by running:

solana address -k ./target/deploy/bt_kyc-keypair.json

Copy and paste this address into ./Anchor.toml and ./programs/bt-kyc

Finally run the following:

anchor deploy 

VII. Client Side Instrumentation

To interact with the program from a NodeJS client we recommend using:

1. @project-serum/anchor to instrument program rpc requests from the client.
2. @solana/web3.js for NodeJS Solana libraries.
3. @civic/solana-gateway-react for Civic's KYC Libraries and React Providers.
4. @solana/wallet-adapter for Solana React wallet adapter components.
