Olympia
Active protocol development for Ethereum Classic: EVM modernization, maintained clients, and funded development through sustainable basefee revenue.
- Fusaka EVM alignment: full parity with every Ethereum tool, library, and framework
- EIP-1559 fee market: predictable gas pricing, basefee revenue redirected to protocol treasury
- Protocol treasury: sustainable funding without new token issuance or miner reward changes
- Institutional infrastructure: the Proof-of-Work foundation for regulated stablecoin issuance (Classic USD, MiCA and GENIUS Act-compliant), digital commodity classification under the CLARITY Act, and the broadest cross-jurisdictional institutional access profile of any Proof-of-Work smart contract network
Block number to be announced on the Olympia Community Developer Calls.
What Olympia Changes
Three client-facing ECIPs that modernize the protocol in a single coordinated upgrade.
EIP-1559 Fee Market
The most widely adopted transaction format in the EVM ecosystem, now on Ethereum Classic. Dynamic gas pricing delivers predictable fees. Unlike Ethereum where basefee is burned, ETC redirects it to the protocol treasury. Miner block rewards and tips remain completely untouched.
Protocol Treasury
A protocol-controlled vault funded by basefee revenue and voluntary contributions. Institutions, developers, and stakeholders can fund Ethereum Classic core development without fielding their own team. No admin keys, no multisig. Only on-chain governance can release funds.
Fusaka EVM Alignment
Building on Mystique and Spiral, Olympia delivers the remaining EVM execution-layer improvements from Dencun, Pectra, and Fusaka: every improvement independent of Proof-of-Stake and blob data availability. Exchanges and wallets gain modern RPC compatibility. Developers gain full access to every current Ethereum tool, library, and framework. One codebase, every EVM chain.
EVM Compatibility in Detail
Three Ethereum upgrade cycles delivered to ETC in a single fork: every execution-layer improvement independent of Proof-of-Stake and blob data availability.
Dencun

Fusaka

Gas & State Access
Account delegation, cheaper calldata, gas limit enforcement, opcode repricing, and jumpdest removal. Reduces transaction costs and enables smart account patterns without protocol changes.
EVM Safety
SELFDESTRUCT restricted to deployment context, stack size enforcement, and call target constraints. Makes contract behavior more predictable and reduces attack surface.
Cryptographic Precompiles
BLS12-381 pairing operations for ZK-friendly proof verification, P256VERIFY for WebAuthn and passkey authentication. Native cryptographic primitives for privacy and identity.
Execution Context
MCOPY for efficient memory operations, historical block hashes in state, transient storage TSTORE/TLOAD. Unlocks reentrancy guards, flash loans, and cross-contract patterns without persistent storage.
Explicitly excluded: all blob-dependent EIPs (EIP-4844, EIP-7516, EIP-7691). Ethereum Classic is a pure Layer 1 execution chain with no data availability requirement. Blobs are L2 scaffolding ETC does not need.
Developer Tooling — Works Without Modification
Solidity 0.8.x+
All recent compiler versions produce compatible bytecode for ETC without modification.
Foundry / Hardhat
Standard EVM testing and deployment toolchains work on ETC without ETC-specific forks or patches.
wagmi / viem / ethers.js
Standard wallet libraries and RPC types work on ETC without patching or overrides. One codebase, every EVM chain.
Global Regulatory Recognition
Ethereum Classic has received formal regulatory classification across four major jurisdictions.
CLARITY Act
Digital Commodity
CFTC · United States
Classified as a digital commodity under CFTC jurisdiction. Proof-of-Work consensus is the defining characteristic for commodity status under US digital asset legislation.
GENIUS Act
Stablecoin Platform
United States
The only Proof-of-Work EVM platform for regulated stablecoin deployment under the GENIUS Act. Positions ETC as the immutable settlement layer for compliant digital dollar infrastructure.
MiCA
Decentralized Asset
European Union
Classified as a decentralized crypto-asset under MiCA, exempt from issuer obligations as a fully decentralized protocol with no central issuer or controlling party.
FSA Green List
Recognized Asset
Japan
Recognized crypto-asset on the FSA Green List via JVCEA. Enables fast-track listing across all Japanese regulated exchanges without additional review requirements.
The Olympia Upgrade
Olympia is Ethereum Classic’s most significant protocol upgrade. Three changes arrive in a single activation: Fusaka EVM alignment, EIP-1559 fee market, and a protocol-managed treasury.
The headline change is full Fusaka EVM parity — closing years of execution-layer divergence from Ethereum in a single fork. Every Solidity compiler version, every deployment tool (Foundry, Hardhat), and every major library (wagmi, viem, ethers.js) works on ETC without modification, patching, or ETC-specific overrides. One codebase deploys to every EVM chain. ETC could not credibly claim this before Olympia. After Olympia, it can.
The EIP-1559 fee market redirects the basefee — value that would otherwise be destroyed — to a protocol-managed treasury. Block rewards and tips remain completely untouched and go entirely to miners. Anyone can submit proposals on-chain. Members vote on resource allocation and execute decisions. Every step is transparent and verifiable on-chain.
How It Works
Funded by basefee revenue, not inflation. Block rewards and tips remain untouched.
Basefee Revenue
Every transaction pays a basefee via EIP-1559. The basefee is directed to the Treasury. Block rewards and tips remain completely untouched. Miners are unaffected.
Protocol Treasury
Protocol-managed vault accumulates basefee revenue, voluntary donations, and mining rewards directed to the treasury address. Real-time monitoring via public dashboard.
On-Chain Governance
On-chain governance via the OpenZeppelin Governor 5.x contract suite. The Olympia DAO handles critical protocol decisions — security maintenance, EVM parity, and client funding — using non-transferable membership NFTs. Futarchy prediction markets open public participation to inform treasury allocation. All on-chain and auditable.
From Proposal to Execution
Five stages from idea to execution — every step on-chain, transparent, and auditable.
Propose
Anyone can submit a governance proposal on-chain. Proposals define the action to execute and the supporting rationale.
Vote
Members cast on-chain votes during a defined voting period via the OpenZeppelin Governor 5.x contract suite. Voting is transparent and immutable.
Queue
Approved proposals enter a security timelock. This delay provides the community time to review before execution.
Execute
After the timelock expires, the proposal executes automatically. Treasury transfers happen on-chain with full auditability.
Disclose
All outcomes are publicly reported and independently verifiable. Proposal records form a permanent on-chain record.
Olympia Roadmap
Five stages from consensus upgrades to permanent protocol integration.
Consensus Upgrades

- Protocol treasury funded by basefee (ECIP-1112)
- Fusaka EVM parity: Dencun, Pectra, Fusaka EIPs (ECIP-1121)

Prediction Markets
ResearchFutarchy-assisted governance uses prediction markets to inform treasury allocation, providing financially-backed public signals alongside on-chain member votes.

Treasury Distribution
FutureGovernance-controlled smoothing curve (ECIP-1115) optionally supplements miner security budgets as fixed-emission block subsidies decline, without touching consensus-layer rewards.
- Treasury smoothing algorithm (ECIP-1115)
- Modeling through ECIP-1017 emission events
- Parameters adjustable without a hard fork
Protocol Integration
FutureProven governance mechanisms elevated from the contract layer to consensus, making treasury rules immutable at the protocol level.
- Consensus-level governance encoding
- Immutable treasury rules
