morpho-rs-api

GraphQL API client for querying Morpho vaults with unified transaction support.

Installation

cargo add morpho-rs-api

Features

• VaultV1Client / VaultV2Client - Dedicated clients for V1 and V2 vault queries
• MorphoApiClient - Combined API client for both vault versions
• MorphoClient - Unified client combining API queries and on-chain transactions
• 30 supported chains - Ethereum, Base, Arbitrum, Optimism, and more
• User position queries - Track positions, PnL, and ROE across chains
• Flexible filtering - Query vaults by chain, curator, APY, and more

Usage

Query-Only Client

use morpho_rs_api::{MorphoClient, Chain};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create an API-only client (no transaction support)
    let client = MorphoClient::new();

    // Query vaults on a specific chain
    let vaults = client.api().get_vaults_by_chain(Chain::EthMainnet).await?;
    for vault in vaults {
        println!("{}: {} (APY: {:.2}%)", vault.symbol, vault.name, vault.net_apy * 100.0);
    }

    Ok(())
}

Full Client with Transaction Support

use morpho_rs_api::{MorphoClient, MorphoClientConfig, Chain};
use alloy_primitives::{Address, U256};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = MorphoClientConfig::new()
        .with_rpc_url("https://eth.llamarpc.com")
        .with_private_key("0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80");

    let client = MorphoClient::with_config(config)?;

    // API queries still work
    let vaults = client.api().get_vaults_by_chain(Chain::EthMainnet).await?;

    // Plus transaction support
    let vault: Address = "0x...".parse()?;
    let amount = U256::from(1000000);

    // V1 vault operations
    let balance = client.vault_v1()?.balance(vault).await?;
    client.vault_v1()?.deposit(vault, amount).await?;

    Ok(())
}

Querying Vaults with Filters

use morpho_rs_api::{MorphoClient, VaultFiltersV1, Chain};

let client = MorphoClient::new();

// Build filters
let filters = VaultFiltersV1::new()
    .chain(Chain::EthMainnet)
    .listed(true)
    .min_apy(0.05); // 5% minimum APY

let vaults = client.api().v1.get_vaults(Some(filters)).await?;

Depositing and Withdrawing

use morpho_rs_api::{MorphoClient, MorphoClientConfig};
use alloy_primitives::{Address, U256};

let config = MorphoClientConfig::new()
    .with_rpc_url("https://eth.llamarpc.com")
    .with_private_key("0x...");

let client = MorphoClient::with_config(config)?;
let vault: Address = "0x...".parse()?;
let amount = U256::from(1000000);

// Deposit to V1 vault
client.vault_v1()?.deposit(vault, amount).await?;

// Withdraw from V2 vault
client.vault_v2()?.withdraw(vault, amount).await?;

Querying User Positions

use morpho_rs_api::{MorphoClient, Chain};
use alloy_primitives::Address;

let client = MorphoClient::new();
let user: Address = "0x...".parse()?;

// Query positions on all chains
let positions = client.api().get_user_vault_positions(user, None).await?;
println!("V1 positions: {}", positions.vault_positions.len());
println!("V2 positions: {}", positions.vault_v2_positions.len());

// Query positions on specific chain
let positions = client.api().get_user_vault_positions(user, Some(Chain::BaseMainnet)).await?;

// Get complete account overview
let overview = client.api().get_user_account_overview(user, Chain::EthMainnet).await?;
println!("Total assets USD: {:?}", overview.state.total_assets_usd);
