Ethereum Classic API

Ethereum Classic came to be after a hard fork in the Ethereum network in 2016. Both blockchains hold the same record data until July of that year with Ethereum Classic (ETC) keeping hold of the original blockchain principles after the fork.

The Ethereum Classic API — build without running a node

Access Ethereum Classic blockchain data through one unified REST API: transaction and address data, balances, block data, and real-time webhooks for on-chain events — with no Ethereum Classic node to run and maintain. Start free and scale as you grow.

Blockchain data

Read Ethereum Classic transactions, addresses, balances, UTXOs, and block data through one REST API.

Real-time webhooks

Subscribe to on-chain events — incoming and outgoing transactions, confirmations, and mined blocks.

No node to run

Skip the infrastructure — managed, always-synced access with no node to operate or maintain.

The original Ethereum blockchain

Both ETC and ETH share the same basic principles and functionalities, Ethereum Classic still facilitates running smart contracts and offers all the same benefit of a decentralized blockchain. The main difference comes down to the consensus algorithm. Ethereum Classic uses the Proof of Work concept while Ethereum is working towards Proof of Stake.
