Intro to onchain development

Setup a local development environment for building onchain programs.

Local Program Development

Create your first Nexis Native Chain onchain program in Anchor.

Intro to Anchor development

Use Anchor's automatic JS/TS clients to send instructions to your program.

Intro to client-side Anchor development

Store arbitrary data on Nexis Native Chain, using PDAs, an inbuilt key-value store.

Anchor PDAs and Accounts

Support the Token Extensions Program from a Client

Use token extensions in onchain programs.

Supporting Token Extensions Program in onchain programs

Include token metadata directly inside the token mint account.

Metadata and Metadata Pointer Extension

Non-Transferable Token

Create a token that allows a fee to be charged each time the token is traded.

Transfer Fee Extension

Create a mint that can be closed once the tokens are burnt.

Close Mint Extension

Compressed NFTs

How state compression - the tech behind compressed NFTs - works, and how to implement it in your own Nexis Native Chain programs.

Generalized State Compression

Learn how to think intelligently about security for your onchain programs, whether developing in Anchor or in Native Rust.

How to approach the Program Security module

Ensure instructions are only ran by authorized accounts by implmementing Signer checks.

Signer Authorization

Understand the use of account owner checks when processing incoming instructions.

Owner Checks

How to check your program's data accounts in both Anchor and Native Rust.
