Your agent needs money. You need control.

Unwall sits between your agent and the financial system — it can only do what you allow.

Your agent needs to send money

Give your agent a USDC wallet. It can send payments via ACH or transfer USDC on-chain — all within the limits you set.

Your agent needs to pay for APIs

x402 lets your agent pay per-API-call with USDC — no subscriptions, no API keys. Just pay and use.

You need to see what happened

Every transaction is logged in real time. See exactly what your agent spent, when, and where.

Your agent needs to buy things

Fund your agent's wallet via ACH or USDC deposit. It can make purchases and transfer funds on your behalf.

Up and running in minutes

No long onboarding. No sales calls. Sign up, fund your wallet, and go.

01

Create a wallet

Sign up and create a project wallet in under a minute. Each wallet holds USDC and is ready to send and receive.

02

Connect your agent

Use our REST API or MCP server. Works with any agent framework that speaks HTTP.

03

Fund and go

Add funds via USDC on-chain or ACH bank transfer. Your agent can now send payments, pay for APIs with x402, and transfer USDC — all within your guardrails.

For developers

One API call to get started

A simple REST API and an MCP server for Claude. Pick what works for you.
