ZetaChain

ZetaChain


ZetaChain API is available on RPC Service (opens in a new tab).

ZetaChain is the foundational, public blockchain that enables omnichain, generic smart contracts and messaging between any blockchain. It solves the problems of “cross-chain” and “multi-chain” and aims to open the crypto and global financial ecosystem to anyone. ZetaChain envisions and supports a truly fluid, multi-chain crypto ecosystem, where users and developers can move between and appreciate the benefits of any blockchain: payments, DeFi, liquidity, games, art, social graphs, performance, security, privacy, and so on.

In order for your Web3 application to interact with ZetaChain — either by reading blockchain data or sending transactions to the network — it must connect to a ZetaChain node. Developers interact with the blockchain using the methods provided by the API.

We support the following networks and protocols for ZetaChain:

Responses come in JSON format (opens in a new tab).

eth_estimateGas

Generates and returns an estimate of how much gas is necessary to allow the transaction to complete.

The transaction will not be added to the blockchain. Note that the estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and node performance.

Parameters

  • id (integer; required): a request ID (example: 1).

  • jsonrpc (string; required): a JSON RPC spec used (example: 2.0).

  • method (string; required): a method used for the request.

  • params (array; required):

    1. <object> (hex encoded): the transaction object:

      • from (string; data, 20 bytes; optional): the address the transaction is sent from.
      • to (string; data, 20 bytes; optional): the address the transaction is directed to.
      • gas (string; quantity; optional): the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.
      • gasPrice (string; quantity; optional): the gas price willing to be paid by the sender in wei.
      • value (string; quantity; optional): the value sent with this transaction, in wei.
      • data (string; data; optional): the hash of the method signature and encoded parameters.
    2. <string> (quantity|tag; optional): either a HEX value of a block number or one of the following block tags:

      • earliest: the lowest numbered block available on the client.
      • finalized: the most recent crypto-economically secure block; cannot be re-orged outside of manual intervention driven by community coordination.
      • safe: the most recent block that is safe from re-orgs under honest majority and certain synchronicity assumptions.
      • latest: the most recent block in the canonical chain observed by the client; this block can be re-orged out of the canonical chain even under healthy/normal conditions.
      • pending: a sample next block built by the client on top of the latest and containing the set of transactions usually taken from local mempool. In other words, it is the block that has not been mined yet.

Returns

  • <string> (quantity): the amount of gas used.
