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
Avalanche	AVX	43114
Base	BASE	8453
Binance Smart chain	BSC	56
Berachain	BERA	80094
Ethereum	ETH	1
Optimism	OPT	10
Polygon	POL	137
Solana	SOL
Tron	TRX	728126428
Worldchain	WLD	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

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
Arbitrum Sepolia	ARB	421614
Avalanche Fuji	AVX	43113
Base Sepolia	BASE	84532
Berachain Bepolia	BERA	80069
BNB Smart Chain Testnet	BSC	97
Bitcoin Testnet	BTC
Ethereum Sepolia	ETH	11155111
Optimism Sepolia	OPT	11155420
Polygon Amoy	POL	80002
Solana Devnet	SOL
Tron Nile Testnet	TRX	3448148188

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

{
  "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

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