RPC Configuration and Errors

API-scoped RPC configuration

The SDK obtains blockchain node configuration from:

GET /api/transaction/config
X-API-Key: <your API key>

The API key selects the tenant and cluster. RpcUrl, Token, TokenExpiration, and FeePayer must be treated as one configuration unit. The SDK rejects missing values, unsupported URL protocols, and fallback values such as jwt_unavailable. It never silently switches to a public Solana endpoint.

Handle structured errors

import { AltudeError } from '@altude/core'

try {
  await gasStation.init()
} catch (error) {
  if (error instanceof AltudeError) {
    console.error(error.code)
    console.error(error.message)
    console.error(error.remediation)
  } else {
    throw error
  }
}

Common network error codes:

Code	Meaning
`RPC_ERROR`	RPC URL or JWT configuration is missing, invalid, or unavailable
`RELAY_ERROR`	The Altude relay rejected a request or could not be reached

Force a refresh

Refresh cached transaction configuration when directed by Altude support or after changing API-key cluster configuration:

const config = await gasStation.getConfig(true)

Retry behavior

Safe network reads may be retried by the HTTP client.
Configuration is refreshed near JWT expiration.
Relay submissions are not automatically repeated after an ambiguous failure.

Do not implement an unconditional retry around transaction submission. A request may have reached the relay even when the client did not receive its response.
