Warning

Unaudited, possibly untested sdk Tulip Protocol takes no responsibility for any (financial, physical, emotional, etc..) damage that results from usage of this sdk, nor makes any guarantee as to the correctness of the sdk. Users of these crates take full responsibility for any mishaps that results from the usage of this sdk.

all crate versions before 0.9.17 are broken and will not work

Overview

tulipv2-sdk is a set of crates for interacting with Tulip V2 vaults, and V1 lending programs via CPI, however it is also usable with off-chain rust clients. The goal of this crate is to provide an easy to use sdk for working with the Tulip Protocol, while also serving as a sort of "configuration file".

There are 4 main crates which are detailed below

Crates

common

The common folder contains a crate tulipv2-sdk-common which bundles together common functionality used by all the other crates, while also containing a module called config which provides configuration variables for easy configuration management. The configuration sub-modules can be enabled/disabled with feature flags enabling you to import only the required dependencies.

common/config/deposit_tracking

Provides configuration variables, traits, and instructions for deposit tracking account management

common/config/levfarm

This module contains files in the form of ray_X.rs for Raydium leveraged yield farms, and orca_X.rs for Orca leveraged yield farms. Additionally a submodule common/config/levfarm/reserves provides configuration variables for all of the lending reserves.

common/config/strategy

This module contains configuration information for the V2 strategy vaults

farms

The farms folder contains a crate tulipv2-sdk-farms which provides an enum named Farm, which is used to describe different platforms (ie Raydium) and farms within those platforms (ie RAY-USDC). In addition to this the farm key itself is used to enable deterministic derivation of vault addresses that are self describing.

The wire representation of the farm type / farm key, is a 2 element slice of u64's, where the first element (farm identifier) is the protocol, and the second element is the particular vault for that protocol.

lending

The lending folder contains a crate tulipv2-sdk-lending which provides very basic support for creating instructions, and issuing CPI calls to Tulip's V1 lending program. It allows for the lending of assets through the Obligation account, while also allowing the caller to refresh obligations and refresh reserves.

leveraged

The leveraged folder contains a crate tulipv2-sdk-leveraged which provides accounts, instructions, and various helper functions for interacting with Tulip's leveraged yield farms

vaults

The vaults folder contains a crate tulipv2-sdk-vaults which provides all v2 vault account types, and associated helper functions, etc..

Examples

The examples folder contains an anchor program that provides usage examples for all of the crates, including lending, leverage farming, v1/v2 vaults, etc.. In addition to this, anchor unit tests are provided which show how to invoke the example program instructions.

The example program uses mainnet account cloning to simulate real-world usage, however due to some peculiarities with mainnet cloned accounts and localnet, certain tests will fail, namely:

  • raydium vault deposit/withdraw
  • v2 strategy vault withdrawals

As such the anchor unit tests will catch these errors masking them to prevent confusion. All such instances are documented both in the anchor unit test comments
