BNB Chain Reth

BNB Chain Reth is a blockchain client based on Reth, designed to provide seamless support for BNB Smart Chain(BSC) and opBNB.

Build from Source

For prerequisites and detailed build instructions please read the Installation Instructions.

With Rust and the dependencies installed, you're ready to build BNB Chain Reth. First, clone the repository:

git clone https://github.com/bnb-chain/reth.git
cd reth

In the realm of BSC, you have the option to execute the following commands to compile bsc-reth:

make build-bsc

Alternatively, you can install reth using the following command:

make install-bsc

When it comes to opBNB, you can run the following commands to compile op-reth:

make build-op

Or, opt for installing op-reth with the command:

make install-op

Run Reth for BSC

Hardware Requirements

• CPU with 16+ cores
• 128GB RAM
• High-performance NVMe SSD with at least 4TB of free space for full node and 8TB of free space for archive node
• A broadband internet connection with upload/download speeds of 25 MB/s

Steps to Run bsc-reth

The command below is for an archive node. To run a full node, simply add the --full tag.

# for mainnet
export network=bsc

# for testnet
# export network=bsc-testnet

./target/release/bsc-reth node \
    --datadir=./datadir \
    --chain=${network} \
    --http \
    --http.api="eth, net, txpool, web3, rpc" \
    --log.file.directory ./datadir/logs

You can run bsc-reth --help for command explanations.

For running bsc-reth with docker, please use the following command:

# for mainnet
export network=bsc

# for testnet
# export network=bsc-testnet

# check this for version of the docker image, https://github.com/bnb-chain/reth/pkgs/container/bsc-reth
export version=latest

# the directory where reth data will be stored
export data_dir=/xxx/xxx

docker run -d -p 8545:8545 -p 30303:30303 -p 30303:30303/udp -v ${data_dir}:/data \
    --name bsc-reth ghcr.io/bnb-chain/bsc-reth:${version} node \
    --datadir=/data \
    --chain=${network} \
    --http \
    --http.api="eth, net, txpool, web3, rpc" \
    --log.file.directory /data/logs

Snapshots

There are snapshots available from the community, you can use a snapshot to reduce the sync time for catching up.

Run Reth for opBNB

The op-reth can function as both a full node and an archive node. Due to its unique storage advantages, it is primarily utilized for running archive nodes.

Hardware Requirements

• CPU with 16+ cores
• 128GB RAM
• High-performance NVMe SSD with at least 3TB of free space
• A broadband internet connection with upload/download speeds of 25 MB/s

Steps to Run op-reth

The op-reth is an execution client for opBNB. You need to run op-node along with op-reth to synchronize with the opBNB network.

Here is the quick command for running the op-node. For more details, refer to the opbnb repository.

git clone https://github.com/bnb-chain/opbnb
cd opbnb
make op-node

It's important to mention that op-node and op-reth both need the same jwt.txt file. To do this, switch to the op-reth workdir and paste the jwt.txt file created during op-node execution into the current workspace.

Here is a quick command for running op-reth. The command below is for an archive node, to run a full node, simply add the --full tag.

# for mainnet
