# Avalanche methods
> Complete reference of supported Avalanche C-Chain and P-Chain JSON-RPC methods on Chainstack, including method availability details.
Our pricing is simple: 1 RU per full request, 2 RUs per archive. For which EVM methods are full vs archive, see [Request units — EVM methods affected by block age](/docs/request-units#evm-methods-affected-by-block-age).
See also [interactive Avalanche API call examples](/reference/avalanche-getting-started).
## Contract chain (C-Chain)
This table reflects the C-Chain surface after the [Helicon upgrade](/docs/avalanche-helicon-upgrade), which removed the `admin`, `warp`, and `personal` namespaces, three `eth` methods, and eight non-trace `debug` methods. Helicon activated on Fuji Testnet on July 28, 2026 and on Avalanche Mainnet on September 22, 2026 at 15:00 UTC.
