Use Case

Enable users to offramp stablecoins into fiat across various chains. This works via setting up an autoramp rule on Iron that offramps stablecoins that are received into that address to your bank account. Examples:
  • Setup wallet address 1 which turns stablecoins (e.g. USDC) into fiat and sends them to your bank account at Deutsche Bank
  • Setup wallet address 2 which turns stablecoins (e.g. USDC) into fiat and sends them to your personal bank account at Revolut

​
Example Flow

1
Max sets up a wallet address 1 owned by Iron
2
Now an autoramp is activated which turns USDC to EUR and is tied to his bank account
3
Max sends 1000 USDC to wallet address 1
4
As soon as funds hit this address, Iron turns them into EUR and pays them to Max’s bank account
5
Max can transfer at any time. This wallet address 1 is persistent.
6
Non supported assets sent to wallet address 1 will be returned to sender

​
Implementation

Follow these example steps to integrate create an autoramp logic for USDC to EUR on Solana.

Now you are ready to show the user their custom wallet address which will be auto-connected to this offramp rule. Please also show supported assets for this wallet address (e.g. EURC, USDC). Non-supported assets will be returned to sender. Related Guide: For more details, refer to the API Reference Documentation.
