Bera

Overview

Berachain is a high-performance EVM-identical L1 blockchain built using the Cosmos SDK and leveraging a unique consensus mechanism called Proof-of-Liquidity (PoL). Unlike traditional proof-of-stake models, Berachain incentivizes liquidity providers by allowing them to stake liquidity positions instead of native tokens, fostering deeper liquidity and aligning incentives between validators and ecosystem participants.

Faucet

You can use a faucet to obtain free testnet tbera for development and testing purposes.

Faucet: Use a cartio faucet funds

Units

Each bera is comprised of 1,000,000,000,000,000,000 (1018) wei, so not even a single bera can be stored numerically without exceeding the range of JavaScript numbers. Gas fees are denoted in gwei.

  • 1 bera = 1018 wei
  • 1 wei = 10-18 bera
  • 1 gwei = 10-9 bera

For that reason, only string balance properties are available, which are balanceString, confirmedBalanceString, and spendableBalanceString.

Fees

BERA supports EIP-1559 gas estimation and accounts for both L2 and L1 components of fees. The eth_estimateGas RPC endpoint provides a value that already includes both L1 and L2 gas costs.

Unlike fixed gas limits, you cannot set a strict 21K upper limit for transactions, as gas requirements fluctuate over time with L1 price variations.

The base fee is the minimum price per unit of gas that a transaction must pay to be included in a block. Transactions must specify a maximum base fee higher than the block base fee to be included. The actual fee charged is the block base fee, even if the transaction specifies a higher maximum base fee.

The priority fee is an additional price per unit of gas paid on top of the base fee. In BERA, transactions with a higher priority fee are prioritized and processed faster. If transaction speed is important to your application, setting a higher priority fee can help ensure quicker inclusion.
