# Supported blockchains

Kima supports a variety of EVM-compatible Layer 1 and Layer 2 chains, as well as Solana, and will ultimately allow the swift and secure transfer of value between the following blockchains:

| Chain               | Short Name | Chain ID                                   |
| ------------------- | ---------- | ------------------------------------------ |
| Arbitrum            | ARB        | [42161](https://chainlist.org/chain/42161) |
| Avalanche           | AVX        | [43114](https://chainlist.org/chain/43114) |
| Base                | BASE       | [8453](https://chainlist.org/chain/8453)   |
| Binance Smart chain | BSC        | [56](https://chainlist.org/chain/56)       |
| Berachain           | BERA       | [80094](https://chainlist.org/chain/80094) |
| Ethereum            | ETH        | [1](https://chainlist.org/chain/1)         |
| Optimism            | OPT        | [10](https://chainlist.org/chain/10)       |
| Polygon             | POL        | [137](https://chainlist.org/chain/137)     |
| Solana              | SOL        |                                            |
| Tron                | TRX        | [728126428](https://tronlink.org/)         |
| Worldchain          | WLD        | [480](https://chainlist.org/chain/480)     |
| Bitcoin             | BTC        |                                            |
| Credit Card         | FIAT       |                                            |
| Bank Account        | FIAT       |                                            |

The short names are used in various API queries. Most are shared across mainnet and testnet, while some can be environment-specific. For a full environment-wide chain inventory, use `get_chains`. For route-specific destinations from a given origin chain, use `get_available_chains/{originChain}`. Click on the chain ID link to visit Chainlist.org and add the chain to your wallet.

> ℹ️ Credit Cards and Bank Accounts are currently supported as the origin network- off ramping to come in a future release. ℹ️ In backend request payloads, FIAT rails may be represented as `CC` and `BANK`, then normalized to `FIAT` before submission. ℹ️ Documentation uses `Berachain` and `Berachain Bepolia` as display names. API responses may use `Bera` or `Berachain`, while the stable short name remains `BERA`.

### Testnet support <a href="#testnet-support" id="testnet-support"></a>

Kima is currently available on the following testnets, which can be used for development and/or testing in the Kima Demo App:

| Chain                   | Short Name | Chain ID                                         |

### Querying for Supported Chains

#### Full environment chain inventory

Use `get_chains` if you want the full list of chains available in a given environment:

* Mainnet: `https://api.kima.network/kima-finance/kima-blockchain/chains/get_chains`
* Testnet: `https://api.sardis.kima.network/kima-finance/kima-blockchain/chains/get_chains`

Response:

* `Chains`: string\[]: the list of supported chain short names for that environment

```json
{
  "Chains": [
    "ETH",
    "POL",
    "AVX",
    "SOL",
    "BSC",
    "ARB",
    "OPT",
    "TRX",
    "BASE",
    "BERA",
    "FIAT",
    "WLD",
    "BTC"
  ]
}
```

#### Route-specific destinations

Use `get_available_chains/{originChain}` if you want the set of destination chains available from a specific origin chain:

* Mainnet: `https://api.kima.network/kima-finance/kima-blockchain/chains/get_available_chains/{originChain}`
* Testnet: `https://api.sardis.kima.network/kima-finance/kima-blockchain/chains/get_available_chains/{originChain}`

Params

* `originChain` (string): the starting chain short name (see above)

Response

* `Chains`: string\[]: the list of chain short names which can be bridged to from the origin chain

```json
{
  "Chains": [
    "POL",
    "AVX",
    "SOL",
    "BSC",
    "ARB",
    "OPT",
    "TRX",
    "BASE",
    "WLD"
  ]
}
```

The example above reflects a mainnet query using `originChain=ETH` on March 10, 2026.
