RPC Endpoints
Ethereum-compatible RPC endpoints
You can use any Ethereum library and tool with the IoTeX blockchain by simply pointing them to an IoTeX Gateway node.
Below, you find a list of official and third-party IoTeX gateways that provide an Ethereum-RPC endpoint, that you can use to configure any Ethereum wallet or developer tool to interact with the IoTeX blockchain:
Checkout the "Run as a Gateway" section of the iotex full-node documentation to learn how to run a full node as a network RPC endpoint.

Example
To get the balance of the IoTeX address ukzv5m6xnsg3gzaec3shew8nw03cch2x53d6v6
you first convert it into the Ethereum address format using ioctl:
which gives you the following Ethereum address:0xE584ca6F469c11140Bb9c4617Cb8f373E38C5D46.
Then you can query the Babel endpoint according to the Ethereum JSON RPC API:
Which returns the balance 0x10f0cf064dd59200000
(hex) for the address, expressed in Rau units (i.e. 5000000000000000000000 Rau, equivalent to 5000 IOTX).

Chain ID
The chainID
chain identifier was introduced by Ethereum in EIP-155
to prevent replay attacks between Ethereum-compatible chains, it is a way to tell chains apart, where Ethereum was assigned a chainID
of 1.
In respect of this EIP
, IoTeX chainIDs
have been picked as follows:
Network | chainID |
---|---|
IoTeX Mainnet |
|
IoTeX Testnet |
|
