Contract Chain

Contract Chain API

Note

Ethereum has its own notion of networkID and chainID. These have no relationship to Avalanche's view of networkID and chainID and are purely internal to the C-Chain. On Mainnet, the C-Chain uses 1 and 43114 for these values. On the Fuji Testnet, it uses 1 and 43113 for these values. networkID and chainID can also be obtained using the net_version and eth_chainId methods.

Ethereum APIs

Endpoints

JSON-RPC Endpoints

To interact with C-Chain via the JSON-RPC endpoint:

/ext/bc/C/rpc

To interact with other instances of the EVM via the JSON-RPC endpoint:

/ext/bc/blockchainID/rpc

where blockchainID is the ID of the blockchain running the EVM.

WebSocket Endpoints

info

On the public API node, it only supports C-Chain websocket API calls for API methods that don't exist on the C-Chain's HTTP API

To interact with C-Chain via the websocket endpoint:

/ext/bc/C/ws

For example, to interact with the C-Chain's Ethereum APIs via websocket on localhost, you can use:

ws://127.0.0.1:9650/ext/bc/C/ws
Tip

On localhost, use ws://. When using the Public API or another host that supports encryption, use wss://.

To interact with other instances of the EVM via the websocket endpoint:

/ext/bc/blockchainID/ws

where blockchainID is the ID of the blockchain running the EVM.

Standard Ethereum APIs

Avalanche offers an API interface identical to Geth's API except that it only supports the following services:

  • web3_
  • net_
  • eth_
  • personal_
  • txpool_
  • debug_ (note: this is turned off on the public API node.)

You can interact with these services the same exact way you'd interact with Geth. See the Ethereum Wiki's JSON-RPC Documentation and Geth's JSON-RPC Documentation for a full description of this API.

info

For batched requests on the public API node , the maximum number of items is 40. We are working on to support a larger batch size.

Avalanche - Ethereum APIs

In addition to the standard Ethereum APIs, Avalanche offers eth_getAssetBalance, eth_baseFee, eth_maxPriorityFeePerGas, and eth_getChainConfig.

They use the same endpoint as standard Ethereum APIs:

/ext/bc/C/rpc

eth_getAssetBalance

Retrieves the balance of first class Avalanche Native Tokens on the C-Chain (excluding AVAX, which must be fetched with eth_getBalance).

Note

The AssetID for AVAX differs depending on the network you are on.

Mainnet: FvwEAhmxKfeiG8SnEvq42hc6whRyY3EFYAvebMqDNDGCgxN5Z

Testnet: U8iRqJoiJm8xZHAacmvYyZVwqQx6uDNtQeP3CQ6fcgQk3JqnK

For finding the assetID of other assets, please note that avax.getUTXOs and avax.getAtomicTx return the assetID in their output.

Signature:

eth_getAssetBalance({
    address: string,
    blk: BlkNrOrHash,
    assetID: string,
}) -> {balance: int}
  • address owner of the asset
  • blk is the block number or hash at which to retrieve the balance
  • assetID id of the asset for which the balance is requested

Example Call:

    utxos: []string,
    endIndex: {
        address: string,
        utxo: string
    }
}
  • utxos is a list of UTXOs such that each UTXO references at least one address in addresses.
  • At most limit UTXOs are returned. If limit is omitted or greater than 1024, it is set to 1024.
  • This method supports pagination. endIndex denotes the last UTXO returned. To get the next set of UTXOs, use the value of endIndex as startIndex in the next call.
  • If startIndex is omitted, will fetch all UTXOs up to limit.
  • When using pagination (that is when startIndex is provided), UTXOs are not guaranteed to be unique across multiple calls. That is, a UTXO may appear in the result of the first call, and then again in the second call.
  • When using pagination, consistency is not guaranteed across multiple calls. That is, the UTXO set of the addresses may have changed between calls.
  • encoding sets the format for the returned UTXOs. Can only be hex when a value is provided.

Example

Suppose we want all UTXOs that reference at least one of C-avax18jma8ppw3nhx5r4ap8clazz0dps7rv5ukulre5.
