# Supported Chain and Contract Address

IDRX has been deployed on many networks. Here you will find the contract address on each network:

| Chain       | Contract Address                            | Decimals |
| ----------- | ------------------------------------------- | -------- |
| Polygon     | 0x649a2DA7B28E0D54c13D5eFf95d3A660652742cC  | 0        |
| BNB Chain   | 0x649a2DA7B28E0D54c13D5eFf95d3A660652742cC  | 0        |
| Base        | 0x18Bc5bcC660cf2B9cE3cd51a404aFe1a0cBD3C22  | 2        |
| Lisk        | 0x18Bc5bcC660cf2B9cE3cd51a404aFe1a0cBD3C22  | 2        |
| Etherlink   | 0x18bc5bcc660cf2b9ce3cd51a404afe1a0cbd3c22  | 2        |
| Kaia        | 0x18bc5bcc660cf2b9ce3cd51a404afe1a0cbd3c22  | 2        |
| World Chain | 0x18bc5bcc660cf2b9ce3cd51a404afe1a0cbd3c22  | 2        |
| Gnosis      | 0x18bc5bcc660cf2b9ce3cd51a404afe1a0cbd3c22  | 2        |
| Solana\*    | idrxZcP8xiKkYk6XGD4uz1dxEYCWSgKDHqgjsBbwDur | 2        |

\*Previous Solana token contract (idrxTdNftk6tYedPv2M7tCFHBVCpk5rkiNRd8yUArhr) has been deprecated. If you still hold tokens from this contract, you may redeem them at a 1:1 ratio, either for IDRX under the latest contract or into Rupiah. Please contact <support@idrx.co> for assistance.

### Decimals

**Decimals** is the smallest fraction of one IDRX that exists on that chain. On **Polygon and BNB Chain there is no fractional unit at all** — the smallest amount is 1 IDRX. Everywhere else IDRX goes down to 0.01.

This is a property of the token on each chain, not a display preference, so it decides which amounts you may send. A mint request whose amount is finer than the target chain allows is rejected with `400` — see [`toBeMinted`](/api/transaction-api/post-api-transaction-mint-request.md#parameters).
