# How it Works

## V1  (Legacy)

AnyToAny.io uses [VIA Messaging](/via-omnichain-network/technology-overview.md) to burn and mint an intermediary / utility token, $PAPER between chains. 

Process Flow:

1. Token A swaps into blockchain native gas coin
2. Blockchain native gas coin swaps into PAPER
3. PAPER is burned on Blockchain A and minted on Blockchain B
4. PAPER on Blockchain B is swapped for the native gas coin on Blockchain B
5. The native gas coin swaps into token B

## V2 Upgrade (Not yet released)

AnyToAny.io uses [VIA Messaging](/via-omnichain-network/technology-overview.md) in conjunction with Circle's [CCTP Network](https://www.circle.com/en/cross-chain-transfer-protocol).

Process Flow:

1. Token A swaps into blockchain native gas coin
2. Blockchain native gas coin swaps into USDC
3. USDC is burned on Blockchain A and minted on Blockchain B
4. USDC on Blockchain B is swapped for the native gas coin on Blockchain B
5. The native gas coin swaps into token B

The entire process, from using USDC on the source chain to receiving the desired tokens on the destination chain is often before you can switch chains in your wallet!
