It seems like the roadmap link here links to a non-existent page.

Link: https://roadmap.ankr.com/b/feature-requests/

RPC endpoint: https://rpc.ankr.com/bsc

When I call eth.getGasPrice(), the suggested gas price returns inconsistent results from 1GWEI to 5GWEI, while the correct return should be 3GWEI (please check https://bsc-dataseed.binance.org/) for the time being. This would cause some problems for end users who use this RPC endpoint in front end codes.

Consider adding these to Postman and linking to them.
Alternatively, test them and add to docs directly

Your docs are out of date, AnkrscanProvider no longer exists, should be AnkrProvider. Also, add some docs with error codes please.

• Let's make sure the docs are meeting user needs by checking in with them and empowering them to easily comment and feedback.

The breadcrumbs in our docs don't do anything when we click on them. Aren't they supposed to be clickable? They should let me easily go back to anything in that list when I click on it. But right now it's just a piece of text that doesn't do anything. Only the home button works.

Is it possible to configure ankr_getTokenHoldersCount to sort the response by balance?

Surely it would make sense for the response to default to returning the biggest holders first...

I can see other methods have a "descOrder" boolean option.

Thanks :)

ankr_getTransactionsByAddress method
Works terribly.
Troubled blockchains:

• polygon (max 100 txs per address to fetch)
• optimism (max 30 txs per address to fetch)
• arbitrum (max ? txs per address to fetch)
  Cannot fetch anymore than that even if I decrease the page size. If I increase, straigh to -32000 error

I would like to ask if the solana chain in Ankr can support WebSocket access. We want to subscribe to transactions through wss instead of requesting transaction history through RPC.

Hello Ankr Team,

I get this error when calling the avalanche c chain rpc endpoint when I want to get the balance of an address. The same method works well with other EVM enpoints:

rpc: service/method request ill-formed: "eth_getBalance"

Add Ethereum Sepolia Testnet support for Advanced API.

https://www.ankr.com/docs/advanced-api/overview/#chains-supported

Multiple RPC providers that support Gnosis are using Nethermind as a client, Ankr being one of those. There is an open ticket on Nethermind (NethermindEth/nethermind#5936) related to the trace_transaction method where multiple RPC providers either return Not Found or fail with an exception, while Ankr is able to produce the correct result.

As part of the debugging process on Nethermind, it would be really useful if you could share which options are you using to run Nethermind in your public RPC (https://rpc.ankr.com/gnosis). The only information that we have right now is the result of web3_clientVersion which is Nethermind/v1.20.1+9f39c0c7/linux-x64/dotnet7.0.9, but this is not enough.

Launching a Full Node on Binance Smart Chain with Erigon

Introduction

This tutorial will demonstrate the following processes:

1. Configuring the remote server to run a full node.
   
2. Building the Erigon Client on Binance Smart Chain from the source code.
   
3. Using Erigon to deploy the full node on Binance Smart Chain.
   

00 Getting Started

0.1 Essential Hardware

0.2 Essential Software

0.3 Enabling / Disabling Secure Shell (SSH)

To access the remote server, the user must enable Secure Shell (SSH) on their system.

# Enable SSH

sudo systemsetup -setremotelogin on
Password: [*****]   # System password

# Disable SSH

sudo systemsetup -setremotelogin off

01 Updating and Configuring the Server

1.1 Connect to the Server via SSH

# Log in with your server admin credentials

ssh <your_username>@<server_ip_address>
Password: [*****]

Tip: Press CTRL+D at anytime to suspend the connection.

1.2 System Updates and Installations

1.2.1 Run Linux Updates

# Update Linux OS
# Upgrade packages
# Remove outdated programs

sudo apt update && sudo apt-dist upgrade -y && sudo apt autoremove -y

1.2.2 Install Go – (Get it Here)

# Download & extract the latest version of Go
# Current: v1.17.8

wget -c https://go.dev/dl/go1.17.8.linux-amd64.tar.gz && sudo tar -C /usr/local -xzf go1.17.8.linux-amd64.tar.gz

# Create a new directory
# Set the $GOPATH environment variable
# Set the $PATH variable to include $GOROOT and $GOPATH

mkdir ~/.go

GOROOT=/usr/local/go && GOPATH=~/.go && PATH=$PATH:$GOROOT/bin:$GOPATH/bin

# Replace existing Go version with the latest version

sudo update-alternatives --install "/usr/bin/go" "go" "/usr/local/go/bin/go" 0 && update-alternatives --set go /usr/local/go/bin/go

# Check for updated version

go version

1.2.3 Create the Server's Home Folder

mkdir ~/srv/svc && cd srv/svc

1.2.4 Install the Essential Ubuntu Packages

# Run as super ('sudo') user

apt install snap
apt install npm
apt install git
apt install make
apt install mdadm

# Install Axel with Snap package

snap install axel

02 Building the Erigon Client

2.1 Install Build Essentials

apt install build-essential

2.2 Clone the Erigon Repository

git clone https://github.com/ledgerwatch/erigon --recursive

2.3 Create a New Folder to Run Erigon

mkdir erigon && cd erigon

make all

2.4 Review the Erigon Files

cd build/bin

echo $PATH

ls -ai

2.5 Copy the Erigon Files to the Local Directory

sudo cp ./* /usr/local/bin

2.6 Move Back into the Erigon Folder

cd ~/srv/svc/erigon/

cd ..

2.7 Verify the Launch Path

which erigon

2.8 List Erigon Commands

erigon --help

03 Running the BSC Node with Erigon

3.1 Update Your Server's Security Settings

3.1.1 Block Unauthorized Access with Fail2Ban

sudo apt install fail2ban -y

3.1.2 Activate Ubuntu Firewall

# Check the Ubuntu Firewall (ufw) status
# Activate Ubuntu Firewall

sudo ufw status

sudo ufw allow ssh

3.2 Sync with Binance Smart Chain

Important: This step will likely take a while to complete.

3.2.1 Sync Normally

erigon --chain=bsc --datadir=/srv/svc --metrics --metrics.addr=0.0.0.0 --metrics.port=6060 --private.api.addr=0.0.0.0:9090 --pprof --pprof.addr=0.0.0.0 --pprof.port=6061

3.2.2 Sync in the Background

nohup bash -c 'erigon --chain=bsc --datadir=/srv/svc --metrics --metrics.addr=0.0.0.0 --metrics.port=6060 --private.api.addr=0.0.0.0:9090 --pprof --pprof.addr=0.0.0.0 --pprof.port=6061'

3.3 Monitor Your Node's Performance with NetData (Optional)

1. Register for a free account.
2. Log into the user portal and select "Connect Nodes."
3. Copy the provided script and run it in the terminal.

wget -O /tmp/netdata-kickstart.sh...

The ankr_getTokenHolders is not returning holders ordered by balance.
Is this by design? What is the reasoning behind it?

I would really like to have an endpoint that returns token holders sorted by balance.

Basically I want to get the top xx holders for a token. But with the current behaviour I would have to query all token holders first (which could be more than one request as the page size is 10k max). Then sort them myself by balance.
Looks like this can be handled more easily server side

Here is a getholders call example:

curl --request POST \
     --url 'https://rpc.ankr.com/multichain/<key>/?ankr_getTokenHolders=' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '
{
  "jsonrpc": "2.0",
  "method": "ankr_getTokenHolders",
  "params": {
    "blockchain": "eth",
    "contractAddress": "0x9F9c8ec3534c3cE16F928381372BfbFBFb9F4D24",
    "pageSize": 10
  },
  "id": 1
}
'

Returns an array with a seamingly random sorting. Maybe it's listing oldest holders first, not sure.

  "id": 1,
  "result": {
    "blockchain": "eth",

I have already made the payment and upgraded to advanced, but why would I still report the following error

Get the token price result: {'jsonrpc': '2.0', 'id': None, 'error': {'message': 'rate limit exceeded', 'data': 'You’ve reached the request limit for free users! Top up your balance to unlock Premium now to skip interruptions and access advanced features https://www.ankr.com/rpc/account/', 'code': -31999}}

Hello my dear Dev colleagues,

I recently tried your Advanced Token API and it's great!

There's one optimization idea for your 'ankr_getTokenPriceHistory'-method though, as I sometimes didn't receive the right token prices on certain requests.
I suggest, that you could implement a 'pairAddress' parameter besides or instead of the already used 'contractAddress' parameter to specify exactly of which token pair liquidity pool the token price has to be fetched from (as there are often multiple and also inofficial pools with totally different token prices) .
