CVault monitors 7 stablecoins every 60 seconds and auto-swaps at your rate threshold gas paid in USDC, zero CELO required.
The problem
African stablecoin holders lose value not from bad assets but from friction, timing, and manual processes that no longer need to be manual.
Manual monitoring is a second job
The NGN/USD rate moves 24/7. Watching it manually means missed windows at 3am, while you're in a meeting, or just living your life.
Rate windows close in minutes
A good swap window can open and close faster than you can act. By the time you've approved the transaction, the rate has moved.
Gas friction in CELO adds up
Most wallets force you to hold CELO for gas. CVault pays gas in USDC via Celo's fee abstraction you never touch CELO.
How it works
Set your threshold
Configure the rate you want e.g. swap when 1 USDm > 1,600 NGNm. Set minimum and maximum swap sizes.
Agent monitors continuously
CVault queries Mento Protocol and Uniswap V3 in parallel every 60 seconds, comparing rates and calculating spread.
Swap executes automatically
When your threshold is met, the agent executes at best rate. Gas paid in USDC. Receipt logged to ERC-8004 reputation registry.
Features
Best-rate routing
Mento Protocol and Uniswap V3 queried in parallel. CVault always picks the better rate — you never leave money on the table.
Gas in USDC
Fee abstraction via Celo CIP-64. The agent wallet never holds CELO. Every transaction uses the USDC gas adapter.
ERC-8004 trust layer
Every autonomous swap submits reputation feedback onchain. Your agent builds a verifiable track record at 8004scan.io.
MiniPay ready
Detects Opera MiniPay automatically. Auto-connects with no popup. Optimised for the 360px mobile viewport and 16M+ MiniPay users.
A2A API + MCP
Other agents can quote rates and execute swaps via the REST A2A API. Developers get an MCP server for Claude, Cursor, and any MCP client. Full docs below.
Non-custodial
Your keys, your tokens. CVault is a read+execute agent it never holds your funds, only executes swaps you've pre-authorised.
Agent interoperability
CVault exposes a REST A2A API and an MCP server so other agents can quote rates and execute swaps without building their own Mento/Uniswap routing, and developers can wire CVault directly into Claude, Cursor, or any MCP-compatible client.
