API / RPC Endpoints

If you are a developer we highly recommend signing up for a free private endpoint through AllThatNode (opens in a new tab), BlockPI (opens in a new tab), InfStones (opens in a new tab), Blast API (opens in a new tab) or one of our other RPC partners. The private endpoints have higher throughput, less restrictions, and will provide a more consistent experience than the public RPCs.

Below is a list of public API endpoints that can be used to interact with ZetaChain from wallet software or web application frontend. Public endpoints are not to be used for backend services or high traffic applications.

ZetaChain is an EVM-compatible blockchain. EVM RPC allows you to connect to the ZetaChain blockchain and interact with the EVM. This gives you direct access to reading Ethereum-formatted transactions or sending them to the network

For example, querying the latest block number:

curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' https://zetachain-athens-evm.blockpi.network/v1/rpc/public

ZetaChain is powered by the Tendermint Core BFT consensus engine. The Tendermint HTTP API allows you to query blocks, information about validators, genesis file, etc.

For example, querying a genesis file:

https://zetachain-athens.blockpi.network/rpc/v1/public/genesis (opens in a new tab)

Tendermint RPC API allows broadcasting transactions and querying the blockchain through an JSON RPC interface.

For example, requesting a specific block:

curl --header "Content-Type: application/json" --request POST --data '{"method": "block", "params": ["3336883"], "id": 1}' https://rpc.ankr.com/zetachain_tendermint_athens_testnet

Tendermint WebSocket API provides access to JSON RPC via WebSockets.

For example, connecting to the WebSocket with wscat

wscat -c wss://zetachain-athens.blockpi.network/rpc/v1/public/websocket

ZetaChain is built with Cosmos SDK. Cosmos SDK HTTP API allows querying the state of the ZetaChain blockchain and broadcast transactions.

For example, querying the latest block:

https://zetachain-athens.blockpi.network/lcd/v1/public//cosmos/base/tendermint/v1beta1/blocks/latest (opens in a new tab)
