Status: waiting for your deposit
You send from your own wallet straight to the exchanger — nothing to connect, no account, and you stay on this page throughout. Rates are indicative until a swap is opened.
The swap is carried out by an independent exchanger and the deposit address above is theirs. starname.me never holds, receives or controls your funds, has no key to that address, and earns a referral commission. Opening a swap sends your receiving address, IP, browser and timezone to the exchanger for their compliance checks; we store none of it. Check their terms, fees and country restrictions before sending anything.
A private RPC endpoint is an exclusive JSON-RPC gateway that only you or your application can use, as opposed to a public endpoint shared by thousands of other users. You need one when the free public endpoints you rely on start failing - returning 429 rate limits, 403 blocks, or degraded performanc
The choice depends on what you need from the connection. Use HTTP for single requests that return a response and close. Use WebSocket when you need ongoing, real-time data - such as pending transactions, new blocks, or log subscriptions - without polling. If your application only sends occasional qu
Your RPC request returns an empty response because the node you are querying either does not have the requested data, is not fully synced, or has rejected your request without sending an error message. The exact cause depends on the type of request, the node's configuration, and the blockchain state
A "connection refused" error on an RPC endpoint means your wallet, dApp, or script tried to reach the RPC server, but the server actively rejected the connection attempt. This is different from a timeout (no response) or a 403/429 (permission or rate-limit block). The fix depends on whether you are
When an RPC endpoint runs out of compute units, every request you send to it fails with an error indicating you have exceeded your provider’s usage limit. You cannot read blockchain data, submit transactions, or call smart contracts through that endpoint until the limit resets or you upgrade your pl
An RPC endpoint URL is a web address your wallet or dApp sends requests to when it needs to read blockchain data or submit a transaction. You interpret it by splitting it into four parts: the protocol, the hostname, the port, and the path. Each part tells you something about who runs the node, what
