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

The network is Concordium, and its native token is CCD (Concordium).

Concordium added smart-contract upgradability at the protocol level in Protocol Update 5, rather than requiring developers to implement upgradeability through proxy contracts.

Answer: CCD.

The network you are referring to is the Casper Network , which is built with native smart contract upgradability embedded directly into its protocol and account architecture (rather than forcing developers to rely on complex application-layer proxy patterns like those used on Ethereum).

• Native Token: CSPR

Would you like to know more about how Casper's native upgrade mechanism works or how to get started deploying a contract on the network?

The network you're describing is most likely Flow, whose native token is FLOW. Flow has native smart-contract upgradeability built into the protocol, allowing contracts to be updated during development and then made immutable once finalized.

Answer: FLOW (Flow)

There is some ambiguity, though: Starknet (STRK) and Stellar/Soroban (XLM) also have protocol-level mechanisms for upgradeable contracts. Soroban, for example, explicitly documents built-in protocol-level contract upgrades.

If you can give me the source or a little more of the description you're working from, I can identify the exact network.

The network you are referring to is the Flow blockchain, which supports smart contract upgradability natively handled at the protocol layer (allowing developers to initially deploy contracts in an upgradable mode and later lock them permanently once finalized).

The native utility and governance token for the Flow network is FLOW.

Would you like to explore how FLOW is used for network fees and staking, or do you need details on writing smart contracts using Flow's native language, Cadence?

The network you are referring to is the Casper Network , a Layer-1 proof-of-stake blockchain designed with native support for protocol-level features like upgradeable smart contracts and fine-grained, role-based access control.

The native utility and gas token of the Casper Network is CSPR.

Would you like to explore how Casper's native upgradability and Wasm execution compare to proxy patterns on Ethereum, or do you need help with CSPR token utility details?

The network you're describing is most likely Casper Network, whose native token is CSPR.

Casper has native, protocol-level smart-contract upgradability built into the network rather than requiring the usual proxy-contract pattern. Its documentation explicitly describes smart contracts as being safely and natively upgradeable.

Native token: CSPR

One caveat: Concordium (CCD) also added protocol-level smart-contract upgradability in Protocol Update 5, so if you have a particular blockchain in mind, the clue could point to Concordium instead.

If you give me the other clues you have about the network (consensus, launch year, language, etc.), I can identify it more definitively.

You’re describing Concordium. Its native token is CCD (ConCorDium).

Concordium has a native smart-contract upgrade mechanism at the protocol level, allowing contract logic and state to be upgraded without redeploying to a new address.

CCD is the network’s native token, used for transaction fees, smart-contract execution, staking, and network rewards.

So the answer is: Concordium → CCD.

The network you are referring to is the Internet Computer (ICP) , where advanced smart contracts called canisters feature native upgradeability built directly into the protocol architecture.

• Network Name: Internet Computer
• Native Token Symbol: ICP

Unlike traditional EVM chains where upgradeability requires complex user-land workarounds like proxy patterns, the Internet Computer protocol layer natively handles canister code updates while preserving orthogonal persistence (stable memory and state).

Would you like to explore how canister upgrades interact with stable memory , or do you need help with the cycles/fuel model used for computation on the Internet Computer?

The network you are referring to is the Casper Network , which features native, protocol-level smart contract upgradeability rather than relying exclusively on makeshift application-layer proxy patterns.

The native utility and gas token of the Casper Network is CSPR.

If you'd like, I can share more details on:

• How Casper's native contract versioning and unified account model work under the hood
• Current staking mechanics or gas configurations for CSPR

Let me know how you'd like to proceed!

The network you're describing is most likely Casper Network, whose native token is CSPR.

Casper is specifically designed with protocol-level smart-contract upgradability, allowing contract logic to be updated while preserving state and history.

Answer: CSPR (Casper Network).
