Mantle

Set up your Mantle RPC node

Requirements

• Setup your Axelar validator
• Minimum hardware requirements: 8 AWS vCPU+, 16GB RAM, 500GB+ SSD free storage space.
• MacOS or Ubuntu 22.04 (tested on 22.04)
• Official Documentation

Prerequisites

Install docker

sudo apt update
sudo apt install snapd
sudo apt-get install jq -y
snap install docker
curl -L https://foundry.paradigm.xyz | bash && source /root/.bashrc && foundryup

• Common Docker Compose Commands

Download configs

git clone https://github.com/mantlenetworkio/networks.git mantlenetworks
cd mantlenetworks

Generate JWT secret and p2p node key

mkdir -p mainnet/secret
node -e "console.log(require('crypto').randomBytes(32).toString('hex'))" > mainnet/secret/jwt_secret_txt
cast w n |grep -i "Private Key" |awk -F ": " '{print $2}' |sed 's/0x//' > mainnet/secret/p2p_node_key_txt

mkdir sepolia/secret
node -e "console.log(require('crypto').randomBytes(32).toString('hex'))" > sepolia/secret/jwt_secret_txt
cast w n |grep -i "Private Key" |awk -F ": " '{print $2}' |sed 's/0x//' > sepolia/secret/p2p_node_key_txt

Update node config

ETH1_HTTP=your_ethereum_mainnet_l1_node
GCMODE=full # or archive

OP_NODE_L1_ETH_RPC=your_ethereum_sepolia_l1_node

Download latest snapshot

Download the latest snapshot for a quicker sync: Mainnet | Testnet

mkdir -p ./data/mainnet-geth
tarball="[latest snapshot].tar"
wget https://s3.ap-southeast-1.amazonaws.com/snapshot.mantle.xyz/${tarball}
tar vxf ${tarball} -C ./data/mainnet-geth

mkdir -p ./data/geth
tarball="[latest snapshot].tar"
wget https://s3.ap-southeast-1.amazonaws.com/static.testnet.mantle.xyz/${tarball}
tar vxf ${tarball} -C ./data/geth

Start the node

docker compose -f docker-compose-mainnetv2.yml up -d

docker compose -f docker-compose-sepolia.yml up -d

An output similar to the following will be shown:

[+] Running 6/6
 ✔ replica 5 layers [⣿⣿⣿⣿⣿]      0B/0B      Pulled
   ✔ 0cdfa0c98ed7 Pull complete
   ✔ da01580fbcc6 Pull complete
[+] Running 1/1
 ✔ Container mantlenetworks-replica-1  Started

After it is done, verify by listing the services and their status

docker compose -f docker-compose-mainnetv2.yml ps

docker compose -f docker-compose-sepolia.yml ps

You should see these 2 services running

RPC Endpoint

echo "$(curl -4 ifconfig.co):8545"

Method 1:

curl -X POST [rpc] -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' | jq

If you get something like this in response to the above rpc call, your node is setup correctly

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x4e4c"
}

You can use a hex to number convertor to get the block height

Method 2:

You can also check your status by connecting to geth console

docker exec -it mantlenetworks-op-geth-1 geth attach http://localhost:8545
> eth.blockNumber
1209 # it will show you the latest block - number here is just an example

You can compare the block height on your node with explorer (mainnet or testnet), use your RPC node only when it has caught up with the latest block height.

Configure vald

In order for vald to connect to your mantle node, your rpc_addr should be exposed in vald’s config.toml

[[axelar_bridge_evm]]
name = "mantle"
rpc_addr = "http://IP:PORT"
start-with-bridge = true

[[axelar_bridge_evm]]
name = "mantle"
rpc_addr = "http://IP:PORT"
start-with-bridge = true
