Why reading and sending is hard

Five things that get hard when you talk to Stellar yourself.

Every app needs live data and a safe way to send. Doing it yourself means running a node and building the safety around it.

01 / 05

A node is a lot to run.

On your ownYou install a Stellar node, let it sync, give it disk, upgrade it when the network changes, and keep someone on call.
With Lumeus RPCOne address per network and a key. Lumeus runs, upgrades and watches the nodes for you.

What you can do

A managed Stellar node, without the node.

12 standard requests Network status, fees, recent transactions and events, current state, preview and send.
Preview before you send Test-run a smart-contract call and see whether it will succeed and what it costs.
Your keys stay yours You sign in your own app. Lumeus only ever sees the signed transaction.
Safe to retry If an answer is lost, you get the payment’s reference to check what happened.
Up to 20 at once Send up to 20 requests together and get each answer back separately.
Live data in web pages Read-only requests straight from your site, with a key that works only there.
Read-only keys Server keys that can read everything but can never send a transaction.
Official tools work The JavaScript, Python and Go Stellar libraries work unchanged with your key.
Clear answers

Every answer tells you what happened.

A reference on every answerEach answer carries a reference that matches your request log, so support can trace it.
Clear time limitsAbout 10 seconds for reads, and up to 30 seconds for previews and sends.
Wait times you can trustWhen you’re over your limit or we’re busy, the answer says exactly how long to wait.

Live from RPC. Everything older from Activity.

RPC covers what’s happening now and the last week. The Activity API picks up from there, back to the start of Stellar. Same key for both.

RPC Send and confirm Preview, submit and follow a transaction until it’s confirmed.
RPC The live network, and the last week Current state, plus recent transactions and events, about 7 days.
Activity API Everything older Full history back to the start of Stellar, in readable form.
