apricot-client's Introduction

apricot-client

Integrating with Apricot on Solana is super easy! We have specifically designed our interface to be as easy-to-use as possible.

Consider these snippets for integrating with Apricot at client-side:

Typescrip:

// get shared connection object
let connection = getConnection();

// pool info
let tokenId = TokenID.USDC;
let assetPoolLoader = await createAssetPoolLoader(connection);
console.log(await assetPoolLoader.getAssetPool(tokenId));

// user portfolio info
let walletKey = new PublicKey(walletAddress);
let portfolioLoader = createPortfolioLoader(walletKey, connection);
await portfolioLoader.refreshPortfolio();
console.log(await portfolioLoader.getUserInfoAddress());
console.log(await portfolioLoader.getUserAssetInfoList());
console.log(await portfolioLoader.getBorrowPowerInfo());

Javascript:

await wrapper.deposit(user_account, user_spl, mints.fake_btc, deposit_amount);

Rust:

let ix = instructions::deposit(user_wallet, &user_spl, deposit_amount, btc_pool_id);
let blockhash = conn.get_recent_blockhash().unwrap();
let tx = Transaction::new_signed_with_payer(&[ix], Some(user_wallet), &[&user_wallet_keypair], blockhash.0);
let result = conn.send_and_confirm_transaction_with_spinner(&tx).unwrap();

apricot-client's Issues

js sample does not work with other private keys

Hi there. sorry for noob question I ve just recently started learning solana.
I tried running node sample.mjs , and it works ok.
But then I just change the private key and nothing more. but it throws the error below:
