Get started with AgentBank

Install @agentbank/sdk, connect to Mantle mainnet, make your first vault deposit, and read live analyst signals — all in under 5 minutes.

This guide walks you through installing the TypeScript SDK, connecting to Mantle, and making your first deposit into an AgentBank vault. By the end you will have a working script that reads vault TVL, deposits assets, and checks your share balance.

Prerequisites

• Node.js 18 or later
• A funded wallet on Mantle Mainnet (chainId 5000) with MNT for gas
• USDC or another supported vault asset

1. Install the SDK

   Install @agentbank/sdk and its peer dependency viem:

   npm install @agentbank/sdk viem
   # or
   pnpm add @agentbank/sdk viem
   
2. Create a client

   import { AgentBankClient } from "@agentbank/sdk";
   import { createPublicClient, createWalletClient, http } from "viem";
   import { mantle } from "viem/chains";
   import { privateKeyToAccount } from "viem/accounts";
   
   const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`);
   
   const publicClient = createPublicClient({
     chain: mantle,
     transport: http("https://rpc.mantle.xyz"),
   });
   
   const walletClient = createWalletClient({
     chain: mantle,
     transport: http("https://rpc.mantle.xyz"),
     account,
   });
   
   const client = new AgentBankClient({
     publicClient,
     walletClient,
     addresses: {
       vault:        "0xC44C061D257Af305dEAea2eD093E878a615d856d",
       signalBoard:  "0x2A46cF6493b377D45908254B0528e38990AA323f",
       intentRouter: "0x9582d2dF303ec2B1fab104A77E249C05571fccC9",
       teeVerifier:  "0x51E52dCBD0FBfaDaDB43ad1EB1Ea0d3A79f128c3",
     },
   });
   

   Store your private key in an environment variable, never hard-code it. Use a .env file with a library like dotenv.

3. Check vault stats

   Before depositing, read the current TVL and estimated APY:

   const tvl = await client.vault.getTVL();
   const apy = await client.vault.getAPY();
   
   console.log(`TVL: ${tvl} USDC`);
   console.log(`Estimated APY: ${apy}%`);
   
4. Deposit into the vault

   Deposit 100 USDC and receive vault shares in return:

   const txHash = await client.vault.deposit({ amount: "100" });
   console.log("Deposit tx:", txHash);
   

   After the transaction confirms, check your share balance:

   const shares = await client.vault.getShares(account.address);
   console.log(`Shares held: ${shares}`);
   
5. Read live signals

   List the most recent analyst signals using the Byreal Skills CLI:

   npx skills add agentbank/skills
   agentbank-cli signals list --status Pending --limit 5 -o json
   

   Or query them programmatically using the subgraph. See Analyst Signals for details.
