Appears as Solana error #8100000; Decode this error by running `npx @solana/errors decode -- 8100000 '…'`
Message
The $argumentLabel argument to the `$methodName` RPC method$optionalPathLabel was `$value`. This number is unsafe for use with the Solana JSON-RPC because it exceeds `Number.MAX_SAFE_INTEGER`.
Placeholders (argumentLabel, methodName, optionalPathLabel, value) are filled from the error’s context. Paste the base64 argument below to see the real values.
What it means
HTTP transport layer errors when talking to an RPC endpoint.
What to do
HTTP 429 means you are rate limited (very common on the public endpoint); use a dedicated provider.
HTTP 403 often means the public RPC rejected a browser or data-centre origin; add an API-keyed endpoint.
5xx responses are provider outages: retry with backoff or fail over.
In development, import from @solana/kit as usual and the full message is thrown. In production the message is stripped to keep bundles small; the error object still carries error.context with the same values this page decodes, and isSolanaError(err, SOLANA_ERROR__RPC__INTEGER_OVERFLOW) lets you branch on it.
