How to Use Roda

Learn how to set up your wallet on Arc Network, create or join savings circles, and interact with the AI Liquidity Guardian.

Roda is deployed on the Arc Testnet, Circle's stablecoin-native Layer 1 chain.

Install an EVM-compatible browser wallet (e.g., MetaMask, Rabby, or Phantom).
Switch your wallet to the Arc Testnet using the chain details:
- Network Name: Arc Testnet
- RPC URL: https://rpc.testnet.arc.network
- Chain ID: 5042002
- Currency Symbol: USDC
Visit the official Circle Faucet, select Arc Testnet, and enter your wallet address to request test USDC tokens for both gas and contract interactions.

You can either initiate a new savings circle or participate in an existing one.

To Create: Go to the "Create Circle" tab on the dashboard. Define the contribution amount per round (e.g., 10 USDC), the number of seats (e.g., 3 members), and the round duration (e.g., 1 hour or 60 seconds for quick testing).
To Join: Locate an active circle in the "Discover" tab, or paste the circle's contract address directly. Review the circle parameters, and click Approve & Join to escrow your security collateral.

Once the circle is fully recruited, rounds start rotating sequentially:

Every round, navigate to the active circle details page and click Contribute to pay your round share.
Once all members pay (or if the round deadline expires), anyone can click Close Round to update the state machine.
The designated beneficiary of the current round can then click Claim Payout to receive the accumulated pot.
After the final round completes, click Withdraw Collateral to reclaim your locked security deposit.

Roda features an on-chain automated risk engine that provides credit safety nets to prevent round defaults.

In the active circle view, scroll down to the **AI Liquidity Guardian** widget.
Observe the agent's **Onchain Identity Verified** card, which displays its ERC-8004 Token ID and live reputation index on Arc Testnet.
Select any circle member and click Analyze Risk to trigger a real-time risk profile evaluation using DeepSeek AI.
If the agent approves the member, click Execute Automated Injection. The Guardian's Developer-Controlled Wallet will autonomously approve and contribution-fund the round, preventing defaults and keeping the savings circle liquid.
