Support and FAQ

If you've got questions, we've got answers. Probably.
👉Where can I go to reach out for technical assistance?
Our discord server is the best place to get in touch with us. https://discord.gg/p7GzDfzyU3 We have a dedicated support section.
👉How many RPCs can I reserve?
As many as you can afford.
👉Can I reserve RPCs in different tiers?
You sure can. You can reserve a Premium+ in NYC and a Premium in Amsterdam if you choose.
👉When I reserve multiple RPCs, are my resources and limits pooled?
No, they are per RPC|per reservation. If you reserve a Premium+ in NYC and a Premium in Amsterdam, the limits of each tier apply to the corresponding RPC.
👉Will you add more regions later?
You can count on it.
👉When do I need to deposit USDC into my account wallet?
Before the current billing cycle ends.
👉Can I withdraw USDC from the account wallet?
Not at this time.
👉How do I know the full USDC amount is going directly to Shadow RPC Operators?
It is all governed by smart contract. You can simply follow the money on-chain.
👉How do I pay for add-ons like Global Server Load Balancing?
Payments for add-ons are debited from the account wallet. Just top up the account wallet before purchasing add-ons.
👉Can I get an Unlimited Package?
We currently enforce rate and data limits to protect the shadow operators, but still believe we are providing the best possible experience. These rate limits are also subject to change with a likelihood of scaling up our limits as more compute becomes available.
👉Are you monitoring the health of the RPCs that Shadow Operators provide?
Sure are. We have an in-house monitoring protocol built that tracks status, health, response times, and delinquency (among other things). If a node is below our health threshold for a given amount of time, it is automatically removed from the Shadow network, and it's USDC emissions are slashed.
👉What is a good transaction timeout threshold (ie, what is a good retry timer)?
No less than 60s with 120s being preferred. Here is an additional resource that can help you https://solanacookbook.com/guides/retrying-transactions.html#facts​
👉How can I tell if the RPC is failing or if the transaction itself is failing?
There's a lot at play here. Let's take a look at some common response codes.
  • If you receive a 200 OK response, that means the RPC accepted the call, and anything that happens after that is up to Toly and Raj.
  • If you get a 500 ERROR response, there's a decent chance something is wrong with the validator.
  • 400 - chances are your payload is busted here. Something is wrong with your request
  • 403 - Chances are you have a request that violates your payment tier (i.e., batching requests with a Basic tier 0 account), but it could also just be a busted payload, or you are calling a deprecated RPC.
  • 429 - You have exceeded the limits of your tier. Consider either scaling your tier up, or scaling your resources out by adding more RPCs and global load balancing.
👉Do I HAVE to use the JWT?
Yes.
👉What if I don't want to?
Too bad.
👉Seriously bro?
Yah brah.
We gave you the sample code to drop in as well as a Docker container that handles it all for you. Just hop right back over to the JWT page and copy pasta. If you struggle with any of it, just drop into Discord and ask for help.
👉There is no mention about getTokenLargestAccounts, does this mean they are included in the base RPS limit ?
gTLA is included
👉For the getMultipleAccounts there is a max limit of 100 accounts, is that honored or is it lower ?
100 account max is honored
👉How are websocket subscriptions counted ?
1 request for the POST call asking for 'connection: upgrade'
👉Is there a penalty for the paid tiers when limits are exceeded (besides the 429 throttling) ?
There are not
