What other networks are you running validators for?
Currently we are mainnet validators in Cosmos, Axelar,Celestia , Dymension,Osmosis, Stader, EigenLayer, Penumbra,Polkadot you can see more info on our website . We participated in more than 100+ testnets.
Based on your participation in any previous testnets, mainnets, are there any best practices to be aware of? What are some things that made previous testnets, mainnet launches successful and/or things to avoid that have gone poorly?
In our opninion is good to start testnet with limited amount of Validators ( you select some genesis testnet validators with good portfolio ) and start testing network with them, in next phase you increase amount of validators etc. If you allow entry to everyone, it may have some problems during upgrades etc, if some validators miss the upgrade. Another problem what we faced during testnets, is that some validator find a way to abuse faucet from genesis block, and he have most of voting power, then if this validator is nor responsible during upgrades (also all network will have issues) so our advise to start with limited amount of validators, and DyDx team distribute testnet tokens to validators to start with.
Do you have a validator voting framework and process?
For voting we have set up our own telegram bot with all chains that we are supporting. Once there is a new proposal, we receive a message in telegram, and we can vote directly from this bot. We always discuss with between each other the subject of new proposal, and also we like to discuss things with community of the project, to hear different opinions, and decide what is the correct choice for future project development. For node monitoring status we use prometheus and grafana.
Are you planning to play any additional roles in the dYdX ecosystem (e.g. market maker, trader, indexer, front-end, other)?
We are full time in crypto, and we are always ready to support projects, and we are ready to contribute our skills, time and energy, if project will choose us, we are always happy to give our best to improve project and help them to develop
Are there other products or services you want to highlight that could be relevant for dYdX?
We are working on some optimization tools for different needs, we have experience team of developers, who can make contributions to DyDx. We just need clear target. Also we provide web services for supported networks. And we have a european license to operate crypto ↔ fiat transactions, and we cooperating with few payment systems ( all european license ).
Any notable contributions in other ecosystems that you would like to highlight for the community?
First of all we provide all web services for your chain
RPC
REST
gRPC
Snapshot
Genesis
Addrbook
Binary
Guide
We can provide archive node, full node, light node etc. ( depends on your needs )
We have rich infrastrcture in different parts of world ( so we can cover every project needs about decentralization ) all bare metal
We are full time in crypto and our team can cover most of the timezones ( as you know crypto has no days off )
We are developing tools suchs as Explorer ( not ping pub fork 
) , discord and telegram bots (for governance, monitoring, proposals), we can write scripts
We can check your code on possible vulnerability, we can test your network for sustainability
We work with Kubernetes, Ansible and TMKMS and our in-huose built monitoring tools
We are one of the biggest relayers in cosmos ecosystem ( opened dozen of channels, and supporting them ) We can do it fast and reliable. We had a request from Archway and Coreum to create multiple new paths for them, and we did it in no time 
you can ask them a feedback about us.
We provide RPC, and we provide canonical RPC with throughput for projetcts ( for example our RPC is integrated into Prax wallet in Penumbra network )
We can support you in private testing on some features that you want to test. For example Namada ( Anoma ) asked us to participate in closed testing by providing infrastructure for it and help test new relayers channels, and governance mechanisms.
We have EU license VASP. Our main services are fiat <=> crypto, we are able to withdraw/deposit EUR and USD - SEPA and SWIFT.
in EUR we are able to achieve T+0 settlements.
We also can help to setup payment account in our partner payment provider, which would allow to reduce banking costs for such crypto-fiat flow.
platfrom capabilities: exchange, withdrawals, deposits, digitally signed transactions reports.
Basically we can be helpful in many ways, as you see and it is also depending on your needs and requests. We can handle a lot of different tasks.
You can some more info in our website, github etc.
