Transactions

Introduction to Celo transactions and gas prices.

warning

As of block height 31,056,500 (March 26, 2025, 3:00 AM UTC), Celo is no longer a standalone Layer 1 blockchain—it is now an Ethereum Layer 2! Some documentation may be outdated as updates are in progress. If you encounter issues, please file a bug report.

For the most up-to-date information, refer to our Celo L2 documentation.

Celo vs Ethereum Transactions​

Transactions in the Celo protocol include payments, contract calls, and other operation which modifies state. They are similar to Ethereum transaction with the following key differences.

  • Gas prices must meet or exceed the gas price minimum.
  • Gas fees may be paid in currencies other than the native CELO.
