Zeta ABI 🧬

Zeta ABI

ABI is Zeta’s cross-program integration ecosystem.

This repository contains the Zeta Cross Program Invocation (CPI) interface as well as a usage example abi-wrapper.

Cross Program Invocations

Instructions

The instructions currently supported are as follows:

• initialize_margin_account - create and initialize a user’s margin account
• initialize_open_orders - create and initialize user’s open orders account
• deposit - deposit USDC collateral into the margin account
• withdraw - withdraw USDC collateral from the margin account
• place_order_v4 - place a futures order of (price, size, side) on the relevant market
• place_perp_order_v2 - place a perp order of (price, size, side) on the relevant market
• cancel_order_xxx - collection of order cancellation functions, by orderId, clientOrderId, market, etc
• close_open_orders - close open orders account
• liquidate - trigger liquidation

Accounts

The accounts and relevant data that is currently supported (non-exhaustive):

• ZetaGroup - contains information relating to all derivatives market for an underlying
  • Underlying
  • Serum Market
  • Strike
  • Kind (Call, Put, Future)
  • Expiry
• Greeks
  • Mark Price
  • Delta
  • Vega
  • IV
• MarginAccount
  • Balance
  • Positions
  • helper functions: get_initial_margin(), get_maintenance_margin(), get_unrealized_pnl()

Programs

abi-wrapper

Basic usage example outlined in a dummy wrapper program, which simply calls the main zeta program instructions. Also includes account layouts and outlines how to read all relevant on-chain data from the Zeta program. This should give all the boilerplate needed to execute core program functionality both as the smart contract and off-chain client.

Modules

• account
• accounts
  An Anchor generated module, providing a set of structs mirroring the structs deriving Accounts, where each field is a Pubkey. This is useful for specifying accounts for a client.
• constants
• context
• cpi
• dex
• errors
• id
• instruction
  An Anchor generated module containing the program’s set of instructions, where each method handler in the #[program] mod is associated with a struct defining the input arguments to the method. These should be used directly, when one wants to serialize Anchor instruction data, for example, when speciying instructions on a client.
• program
  Module representing the program.
• utils

Functions

• entry
  The Anchor codegen exposes a programming model where a user defines a set of methods inside of a #[program] module in a way similar to writing RPC request handlers. The macro then generates a bunch of code wrapping these user defined methods into something that can be executed on Solana.
