# Smart Contract Integratio

Normal is a non-custodial interface that connects users to established DeFi protocols on Stellar. We don't deploy our own custody or lending contracts. Instead, we integrate with audited, battle-tested infrastructure built by the leading teams in the Stellar ecosystem.

All contracts listed below are deployed on Stellar mainnet ✨

#### Savings

When you supply USDC to your Normal savings account, your funds flow into a DeFindex vault, which then deposits into Blend Capital's lending pool. DeFindex is the leading yield-optimization protocol on Stellar, and Blend is its leading lending protocol.

| Contract            | Address                                                    |
| ------------------- | ---------------------------------------------------------- |
| DeFindex USDC Vault | `CAWM7NKSYG2ITJW2MYYJWJ5ULGCJLDB6MXZIWPL3VPRG5TDVLJ66IMWR` |
| Blend Lending Pool  | `CDVQVKOY2YSXS2IC7KN6MNASSHPAO7UN2UR2ON4OI2SKMFJNVAMDX6DP` |

#### Swap

When you exchange assets through Normal's Swap page, the transaction is routed through SoroSwap's router. SoroSwap is Stellar's leading decentralized exchange.

| Contract        | Address                                                    |
| --------------- | ---------------------------------------------------------- |
| SoroSwap Router | `CAG5LRYQ5JVEUI5TEID72EYOVX44TTUJT5BQR2J6J77FH65PCCFAJDDH` |

#### Tokens

| Asset | Address                                                    |
| ----- | ---------------------------------------------------------- |
| USDC  | `CCW67TSZV3SSS2HXMBQ5JFGCKJNXKZM7UQUWUZPUTHXSTZLEO7SJMI75` |
| XLM   | Native asset                                               |
