# RPC restrictions

> No RPC methods are blocked on Supanode. Heavy methods like getProgramAccounts cost more RPS units; archival mode and multi-region are not available in v1.

<Note>RPC restrictions are validated by Supanode engineering for v1, pending final sign-off before public launch.</Note>

What you should know about edge cases on Supanode RPC.

## No methods are explicitly disabled

Supanode supports every method in the [official Solana RPC spec](https://solana.com/docs/rpc/http). RPC traffic is governed by the method weight system rather than a blocklist, so heavy calls stay available but cost more. (For comparison, [gRPC](https://supanode.xyz/docs/solana/grpc/restrictions) and [WebSocket](https://supanode.xyz/docs/solana/websocket/restrictions) do block specific high-traffic subscriptions.)

Methods that touch many accounts or scan large indexes cost more RPS units per call:

- `getProgramAccounts` costs 30 RPS units per call.
- `getTransaction` costs 10.
- See [Limits](https://supanode.xyz/docs/solana/rpc/limits#which-rpc-methods-cost-more-than-one-request-unit) for the full table.

This means a 100 RPS plan handles ~100 simple `getAccountInfo` calls per second, but only ~3 `getProgramAccounts` calls per second. The plan's price reflects this implicit budget.

## Known constraints

- **No archival mode toggle.** All Supanode nodes are configured the same way. There's no separate "archival" tier - history depth is what the network provides.
- **Single region in v1.** All nodes serve from Frankfurt. Multi-region is on the roadmap.

## What you can do instead

- **For heavy-program scans** - use [gRPC](https://supanode.xyz/docs/solana/grpc/overview) `accounts` subscription with filters instead of polling `getProgramAccounts`.
- **For historical replay** - `getSignaturesForAddress` plus per-signature `getTransaction` works for historical transaction lookups.
- **For TLS-encrypted gRPC streams** - [Dedicated Node](https://supanode.xyz/docs/solana/dedicated/node).
