Yield is here in private beta: managed wallets can earn on the USDC they hold. Also new: a public Security page, a hosted BlindPay MCP with no local setup, two new networks, a prompt library and open-amount PIX codes on Payables.

<!--more-->

## TL;DR

- **Yield (private beta)**: turn it on for a managed wallet and the idle USDC balance starts earning
- **Security page**: how we protect your funds and data, in one place at [blindpay.com/security](/security)
- **Hosted MCP**: connect Claude, ChatGPT, Cursor or any MCP client to BlindPay by signing in, nothing to install
- **Tempo and Arc**: two new networks for wallets, payins, payouts and transfers
- **Prompt library**: ready-to-paste prompts that build a full BlindPay integration with your AI coding agent
- **Payables**: pay PIX codes that leave the amount open

## Yield (private beta)

Managed wallets can now earn on the stablecoins they hold. Turn yield on once per wallet and BlindPay moves the idle USDC into a lending vault, keeps it earning, and pulls it back automatically whenever a payout or transfer needs the funds. Turn it off and the full position returns to the wallet. There is no fee on the balance, only a performance fee on gains, and the APY we report is already net of it.

Yield is in private beta. If you want it on your instance, reach out to your BlindPay contact. [Read the Yield guide](/docs/yield).

## Security page

We published a Security page that brings together how we protect your funds and data: infrastructure, encryption, access controls, compliance frameworks and how to report a vulnerability. [Visit blindpay.com/security](/security).

## Hosted MCP: connect your AI agent in one step

The BlindPay MCP now runs hosted at `mcp.blindpay.com`. Add it to Claude, ChatGPT, Cursor or any other MCP client, sign in with your BlindPay account, choose the instance, and you are connected. No local server to run, no API key to paste, and you can see and revoke every connected app from the dashboard under Settings. [Get started with Build with AI](/docs/build-with-ai).

## Tempo and Arc networks

Tempo and Arc are live for managed wallets, offramp wallets, payins, payouts and transfers. Tempo supports USDC.e and USDT0, Arc supports USDC. Both have a matching testnet on development instances. [See the supported networks](/docs/blockchain-wallets).

## Prompt library

We published a library of prompts that walk an AI coding agent through a complete BlindPay integration, from a payin or payout quickstart to payables and wallets, with the API gotchas already encoded. Copy one into your agent and let it build. [Browse the prompts](/prompts).

## Payables: pay PIX codes with an open amount

Static merchant PIX QR codes usually leave the amount to the payer. Payables now accepts them: register the code with the amount you want to pay and BlindPay settles it. The same QR can be paid as many times as needed. [Read the PIX and boleto guide](/docs/payable-boleto-pix).
