Install
npm install @morpho-org/blue-sdk
yarn add @morpho-org/blue-sdk
Getting Started
Fetch the config of a specific market
Leverage the MarketConfig
class to fetch and query minimal information on a given market's immutable configuration:
import { MarketConfig } from "@morpho-org/blue-sdk";
const config = MarketConfig.fetch(
"0xb323495f7e4148be5643a4ea4a8221eef163e4bccfdedc2a6f4696baacbc86cc",
provider // Ethers provider.
);
market.collateralToken; // e.g. 0x7f39C581F595B53c5cb19bD0b3f8dA6c935E2Ca0.
Fetch data of a specific market
Leverage the Market
class to fetch and query useful information on a specific market:
import { Market } from "@morpho-org/blue-sdk";
import { Time } from "@morpho-org/morpho-ts";
const market = Market.fetchFromId(
"0xb323495f7e4148be5643a4ea4a8221eef163e4bccfdedc2a6f4696baacbc86cc",
provider // Ethers provider.
);
// Or from a config, to fetch faster:
// const market = Market.fetchFromConfig(
// config,
// provider // Ethers provider.
// );
market.utilization; // e.g. 92% (scaled by WAD).
market.liquidity; // e.g. 23_000000n (in loan assets).
market.apyAtTarget; // e.g. 3% (scaled by WAD).
const accruedMarket = market.accrueInterest(Time.timestamp()); // Accrue interest to the latest's timestamp.
accruedMarket.toSupplyAssets(shares); // Convert supply shares to assets.
Fetch data on the position of a specific user on a specific market
Leverage the Position
class to fetch and query useful information about the position of a user on a given market:
import { Position } from "@morpho-org/blue-sdk";
import { Time } from "@morpho-org/morpho-ts";
const position = AccrualPosition.fetchFromId(
"0x7f65e7326F22963e2039734dDfF61958D5d284Ca",
"0xb323495f7e4148be5643a4ea4a8221eef163e4bccfdedc2a6f4696baacbc86cc",
provider // Ethers provider.
);
// Or from a config, to fetch faster:
// const position = AccrualPosition.fetchFromConfig(
// "0x7f65e7326F22963e2039734dDfF61958D5d284Ca",
// config,
// provider // Ethers provider.
// );
position.borrowAssets; // e.g. 23_000000n (in loan assets).
position.isHealthy; // e.g. true.
position.maxBorrowableAssets; // e.g. 2100_000000n (in loan assets).
const accruedPosition = position.accrueInterest(Time.timestamp()); // Accrue interest to the latest's timestamp.
position.borrowAssets; // e.g. 23_500000n (in loan assets).
