How to deposit into and redeem from the IXS Permissionless Vault on BNB Chain, using the Studio, the API, or an AI agent.
The IXS Permissionless Vault is an RWA yield vault on BNB Smart Chain, backed by BlackRock’s SHYG high-yield corporate-bond ETF. You deposit USDC and earn the vault’s yield. It’s non-custodial: you sign every transaction with your own wallet.There are three ways to use it: the API, an AI agent, or the Compass widget. They all do the same thing.
The IXS vault is part of the Tokenized Assets product, on BNB Chain. Deposits and redemptions run through your Tokenized Assets Account.
Any EVM wallet that can connect to BNB Smart Chain (MetaMask, Rabby, or an embedded wallet).

USDC on BNB Chain
Deposits are in USDC on BNB, the Binance-Peg token at 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. If your USDC is on another chain, bridge it over or buy it with the On-Ramp.
3
A little BNB for gas
BNB Chain fees are paid in BNB; a dollar or two is enough. With gas sponsorship, your users need none.
4
A Compass API key (API and agent lanes)
Get a free key from the login page. The Studio lane doesn’t need one; each tab below shows where to use it.
Deposits mint instantly. Redemptions don’t. You submit a request and the vault operator settles it later, within a defined window. There is no instant sell for this vault, so don’t expect a same-second withdrawal. Each tab below covers the redemption steps.
Each tab covers the whole flow: deposit, check your position, redeem.
API
AI agent
Studio (demo)
Send your API key as the x-api-key header on every call (shown below). Each call returns an unsigned transaction (or an EIP-712 payload) that you sign. Full reference: Tokenized Assets.Deposit

Create your account on BNB
Idempotent. If the account already exists, transaction comes back null.
Once finalized, move the USDC from your account back to your wallet with the transfer endpoint (action: WITHDRAW).
To look up the vault address: GET /v2/tokenized_assets/markets?provider=ixs&chain=bsc.
Have an AI agent (Claude Code, Cursor, Codex) run the flow. It builds the transactions; you sign them.The Agent Skill is the easiest way in — it sets up the tooling for you (either the compass CLI or the Compass MCP server) and turns your plain-English request into the right commands. You don’t have to set up MCP or the CLI yourself; the two sections after the Skill just explain what it connects to.Agent Skill (start here). In your terminal, set the key first, then start your agent from that same terminal — the order matters, because the agent only picks up the key if it was set before the session began. Swap <key> for the key you got above:
export COMPASS_API_KEY_AUTH=<key> # 1. set the key# 2. then start your agent here — Claude Code (`claude`), Codex, Cursor, or any other
(If your agent is already open, restart it here so it inherits the key.) Installing the Skill is a one-time step that happens inside your agent, not the terminal — in Claude Code, for instance, you type /plugin install right in the chat. It’s a little different per agent, so the Agent Skill page has the exact steps for Claude Code, Cursor, Codex, and others. Once it’s installed, it sets up the CLI or MCP for you and turns plain English into commands. Then just ask:
"Deposit 100 USDC into the IXS vault(0xc975a3EeF2e49F8eDdEf585340C43f15300fCB82) on BNB Chain, then show my position.""Request a redemption of my IXS vault shares on BNB, tell me when it's finalized,then withdraw my USDC."
MCP server. The Compass MCP server plugs into any MCP client (Claude Code, Cursor). The Skill can connect it for you, or you can add it yourself with your key as the X-API-Key header. Nothing to install — every Compass product becomes a tool the agent can call.CLI. The compass CLI is a command-line tool the agent runs in your terminal. The Skill installs it for you, or you can install it yourself; either way it reads the COMPASS_API_KEY_AUTH you set above. The IXS flow is:
# One-time: create your account on BNB, then send USDC on BNB to that addresscompass tokenized-assets create-account --sender 0xYourWallet --owner 0xYourWallet --chain bsc# Deposit into the IXS vault, then check your positioncompass tokenized-assets buy \ --token-in USDC --token-out 0xc975a3EeF2e49F8eDdEf585340C43f15300fCB82 \ --amount-in 1000 --slippage 0.005 --owner 0xYourWallet --chain bsccompass tokenized-assets positions --owner 0xYourWallet --chain bsc# Redeem, then poll until finalizedcompass tokenized-assets sell \ --token-in 0xc975a3EeF2e49F8eDdEf585340C43f15300fCB82 --token-out USDC \ --amount-in 500 --slippage 0.005 --owner 0xYourWallet --chain bsccompass tokenized-assets redemptions --owner 0xYourWallet --chain bsc --vault ixv1
Each write command returns an unsigned transaction { to, data, value, gas }. You sign and broadcast it yourself. From the terminal, use Foundry’s cast with an encrypted keystore so no private key sits on the command line:
# one-time: import your key into an encrypted keystore named "my-keystore"cast wallet import my-keystore --interactive# sign and broadcast the tx the compass command returnedcast send <to> <data> \ --value <value> \ --gas-limit <gas> \ --rpc-url $BSC_RPC_URL \ --account my-keystore
Pass the API’s gas value through as --gas-limit. The transaction runs through your Tokenized Assets Account, which is a smart account, and cast’s own gas estimate can come in too low. When it does, the transaction reverts with GS013.
--dry-run previews any compass command without sending it; --help lists the flags.
The Studio is a demo for previewing the widget, not a frontend your users transact through. To offer this flow to your own users, embed the Compass widgets (@compass-labs/widgets) in your own app. See Widgets.
You can try the flow yourself in the Compass Studio (no API key needed), which opens on the Tokenized Assets widget. This is what the widget does:Deposit
1
Connect a wallet
Click Connect and approve it in your wallet.
2
Switch to BNB Chain
Set the chain switcher to BNB Chain. The IXS vault only appears on BNB.
3
Deposit USDC
Tap Deposit, enter an amount, and confirm. This moves USDC from your wallet into your Tokenized Assets Account.
4
Buy the vault
Open the IXS vault, enter an amount, and confirm. Your USDC becomes vault shares. The balance shows under your holdings.
Redeem
1
Request a redemption
Open your IXS holding, tap Sell / Redeem, enter an amount, and confirm.
2
Withdraw once it settles
The widget shows the request status. When it settles, tap Withdraw to send the USDC back to your wallet.
Redemptions settle asynchronously. The vault operator finalizes them on its own schedule, not instantly. Poll GET /v2/tokenized_assets/redemptions until the request reads finalized, then withdraw. There is no instant secondary market for this vault.
Does Compass hold my funds?
No. Every deposit, redemption, and withdrawal comes back as an unsigned transaction (or EIP-712 payload) that you sign with your own wallet.
