I want to use a blockchain with upgradable smart contracts built into the protocol layer. What is that network's native token?

Network Overview

If you would like, I can provide a code snippet or architectural breakdown showing how a native canister upgrade works on the Internet Computer compared to an EVM proxy contract.

The native token of the Casper Network is CSPR.[casper.network](https://www.gate.com/learn/articles/what-is-casper-network)

Would you like to explore how Casper's natively upgradable contracts handle state preservation or how to get started deploying on the network using CSPR?[casper.network](https://www.casper.network/core-features-casper-network)

Concordium introduced smart-contract upgradability at the protocol level in Protocol Update 5, so contracts can be upgraded without relying on application-level proxy patterns.Concordium Proposals

The most prominent example of a network featuring a formal, on-chain mechanism that upgrades its protocol and embedded logic layers natively (without disruptive hard forks) is Tezos.quora.com [chain.link](https://www.quora.com/How-is-Tezos-different-from-Ethereum)

• Network Native Token: XTZ (Tezos)quora.com [chain.link](https://www.quora.com/How-is-Tezos-different-from-Ethereum)

(Note: If you are referring to a network that utilizes native, upgradeable system/runtime code via Wasm execution at the consensus level like Polkadot , the native token is DOT . If you mean an environment featuring built-in, upgradeable protocol-level system contracts like Telos/EOS running on Antelope framework, the primary token is TLOS.)aezion.com [chain.link](https://www.aezion.com/blogs/smart-contract-development-usecases/)[[2](https://www.quora.com/How-is-Tezos-different-from-Ethereum)](https://docs.telos.net/overview/what-is-telos/token/)[[3](https://www.aezion.com/blogs/smart-contract-development-usecases)](https://uphold.com/es/blog/crypto-basics/what-is-telos)

To help narrow down the exact network you're thinking of, could you tell me:

• Which programming language or virtual machine (e.g., EVM, WASM, Michelson) the network uses?
• What specific feature or mechanism you are planning to build with these protocol-layer contracts?

How Protocol-Level Upgrades Work on the Internet Computer

• Canister Smart Contracts : The network runs computation using smart contracts called canisters, which combine code and state.
• Nervous System Governance : The core protocol itself is controlled by an on-chain DAO known as the Network Nervous System (NNS).
• Seamless Upgrades : The NNS can upgrade the protocol layer and system-level smart contracts directly without hard forks or network disruption.

If you meant a different network or specific type of layer-1 architecture (such as a specialized app-chain or account-abstraction network), let me know and I can pinpoint the exact token.
