Solana Perpetuals

Introduction

Solana Perpetuals protocol is an open-source implementation of a non-custodial decentralized exchange that supports leveraged trading in a variety of assets.

Quick start

Setup Environment

  1. Clone the repository from https://github.com/askibin/perpetuals.git.
  2. Install the latest Solana tools from https://docs.solana.com/cli/install-solana-cli-tools. If you already have Solana tools, run solana-install update to get the latest compatible version.
  3. Install the latest Rust stable from https://rustup.rs/. If you already have Rust, run rustup update to get the latest version.
  4. Install the latest Anchor framework from https://www.anchor-lang.com/docs/installation. If you already have Anchor, run avm update to get the latest version.

Rustfmt is used to format the code. It requires nightly features to be activated:

  1. Install nightly rust toolchain. https://rust-lang.github.io/rustup/installation/index.html#installing-nightly
  2. Execute git config core.hooksPath .githooks to activate pre-commit hooks.

[Optional] Vscode setup

  1. Install rust-analyzer extension
  2. If formatting doesn't work, make sure that rust-analyzer.rustfmt.extraArgs is set to +nightly

Build

First, generate a new key for the program address with solana-keygen new -o <PROG_ID_JSON>. Then replace the existing program ID with the newly generated address in Anchor.toml and programs/perpetuals/src/lib.rs.

Also, ensure the path to your wallet in Anchor.toml is correct. Alternatively, when running Anchor deploy or test commands, you can specify your wallet with --provider.wallet argument. The wallet's pubkey will be set as an upgrade authority upon initial deployment of the program. It is strongly recommended to make upgrade authority a multisig when deploying to the mainnet.

To build the program run anchor build command from the perpetuals directory:

cd perpetuals
anchor build

Test

Unit tests are executed with the cargo test command:

cargo test -- --nocapture

Integration tests (Rust) can be started as follows:

cargo test-bpf -- --nocapture

Integration tests (Typescript) can be started as follows:

npm install
anchor test -- --features test

By default, integration tests are executed on a local validator, so it won't cost you any SOL.

Deploy

To deploy the program to the devnet and upload the IDL use the following commands:

anchor deploy --provider.cluster devnet --program-keypair <PROG_ID_JSON>
anchor idl init --provider.cluster devnet --filepath ./target/idl/perpetuals.json <PROGRAM ID>

Initialize

A small CLI Typescript client is included to help you initialize and manage the program. By default script uses devnet cluster. Add -u https://api.mainnet-beta.solana.com to all of the commands if you plan to execute them on mainnet.

To initialize deployed program, run the following commands:

cd app
npm install
npm install -g npx
npx ts-node src/cli.ts -k <ADMIN_WALLET> init --min-signatures <int> <ADMIN_PUBKEY1> <ADMIN_PUBKEY2> ...

Where <ADMIN_WALLET> is the file path to the wallet that was set as the upgrade authority of the program upon deployment. <ADMIN_PUBKEY1>, <ADMIN_PUBKEY2> etc., will be set as protocol admins, and min-signatures will be required to execute privileged instructions. To provide multiple signatures, just execute exactly the same command multiple times specifying different <ADMIN_WALLET> with -k option. The intermediate state is recorded on-chain so that commands can be executed on different computers.

To change protocol admins or minimum required signatures, run:

npx ts-node src/cli.ts -k <ADMIN_WALLET> set-authority --min-signatures <int> <ADMIN_PUBKEY1> <ADMIN_PUBKEY2> ...

To validate initialized program:

npx ts-node src/cli.ts -k <ADMIN_WALLET> get-multisig
npx ts-node src/cli.ts -k <ADMIN_WALLET> get-perpetuals

Before the program can accept any liquidity or open a trade, you need to create a token pool and add one or more token custodies to it:

npx ts-node src/cli.ts -k <ADMIN_WALLET> add-pool <POOL_NAME>
npx ts-node src/cli.ts -k <ADMIN_WALLET> add-custody <POOL_NAME> <TOKEN_MINT> <TOKEN_ORACLE> <IS_STABLE>

Where <POOL_NAME> is a random name you want to assign to the pool, <TOKEN_MINT> is the mint address of the token, and <TOKEN_ORACLE> is the corresponding Pyth price account that can be found on this page. <IS_STABLE> specifies whether the custody is for a stablecoin. For example:

npx ts-node src/cli.ts -k <ADMIN_WALLET> add-pool TestPool1
npx ts-node src/cli.ts -k <ADMIN_WALLET> add-custody TestPool1 So11111111111111111111111111111111111111112 J83w4HKfqxwcq3BEMMkPFSppX3gqekLyLJBexebFVkix false

To validate added pools and custodies, run:

npx ts-node src/cli.ts -k <ADMIN_WALLET> get-pool <POOL_NAME>
npx ts-node src/cli.ts -k <ADMIN_WALLET> get-custody <POOL_NAME> <TOKEN_MINT>

or

npx ts-node src/cli.ts -k <ADMIN_WALLET> get-pools
npx ts-node src/cli.ts -k <ADMIN_WALLET> get-custodies <POOL_NAME>

CLI offers other useful commands. You can get the list of all of them by running the following:

npx ts-node src/cli.ts --help

UI

We have implemented a coressponding UI for the smartcontract, written in Typescript/Tailwind/Next. To quickly spin up a UI linked to the contract, first follow the previous directions to build the contract, and to init the exchange.

In the main directory, run ./migrations/migrate-target.sh to copy over the target build directory to the ui.

Now, you can use the following CLI commands to quickly spin-up a TestPool1 consisting of the three following tokens.

Sol Token: J83w4HKfqxwcq3BEMMkPFSppX3gqekLyLJBexebFVkix

Test Token oracle: BLArYBCUYhdWiY8PCUTpvFE21iaJq85dvxLk9bYMobcU

USDC oracle: 5SSkXsEKQepHHAewytPVwdej4epN1nxgLVM84L4KXgy7

cd app

npx ts-node src/cli.ts -k <ADMIN_WALLET> add-pool TestPool1

npx ts-node src/cli.ts -k <ADMIN_WALLET> add-custody TestPool1 So11111111111111111111111111111111111111112 J83w4HKfqxwcq3BEMMkPFSppX3gqekLyLJBexebFVkix

npx ts-node src/cli.ts -k <ADMIN_WALLET> add-custody TestPool1 6QGdQbaZEgpXqqbGwXJZXwbZ9xJnthfyYNZ92ARzTdAX BLArYBCUYhdWiY8PCUTpvFE21iaJq85dvxLk9bYMobcU

npx ts-node src/cli.ts -k <ADMIN_WALLET> add-custody TestPool1 Gh9ZwEmdLJ8DscKNTkTqPbNwLNNBjuSzaG9Vp2KGtKJr 5SSkXsEKQepHHAewytPVwdej4epN1nxgLVM84L4KXgy7 true

Now, use the following commands to build and run the UI, (navigate to localhost:3000 to use the UI):

cd ../ui
yarn install
yarn dev
