Seismic proposes Encrypted EVM privacy
- Developers on X outlined Seismic, an Encrypted EVM project for private finance that supports Solidity tooling, in a detailed thread today comparing to Canton. - Posts described privacy primitives, developer compatibility and use cases for confidential DeFi and private transactions on EVM-compatible chains with examples and links in thread. - The thread appeared alongside other Solana and privacy project discussions on X today and included code snippets.

1/ Seismic is a new project proposing an Encrypted EVM—think Ethereum Virtual Machine but with built-in privacy for confidential finance. Developers detailed it in a thread on X today, positioning it as a Solidity-friendly alternative to projects like Canton for private DeFi and transactions on EVM chains. 2/ At its core, Seismic encrypts EVM execution using fully homomorphic encryption (FHE). This lets smart contracts process data without decrypting it first, enabling private computations on-chain. The thread highlights primitives like private state transitions and confidential token transfers, all compatible with existing Solidity code. 3/ Why EVM specifically? Ethereum dominates developer tooling—Solidity, Hardhat, Foundry—and has billions in TVL. Seismic ports this ecosystem to privacy without rewrites: deploy your existing contracts to an Encrypted EVM rollup or sidechain. No new languages needed. 4/ Comparison to Canton: Digital Asset's Canton Network uses Daml for privacy across chains, but it's not EVM-native. Seismic sticks to Solidity while adding FHE privacy layers, claiming faster dev onboarding and broader compatibility for DeFi apps. "Canton is great for enterprises; Seismic unlocks DeFi privacy," the thread states. 5/ Key use cases outlined: Confidential lending (hide borrower collateral), private AMMs (swap without MEV leakage), and zk-proofless private payments. Example: A Solidity ERC-20 token where balances are encrypted, but transfers validate via FHE proofs. Code snippet in the thread shows a private balance check: `function privateBalance(address user) public view returns (uint256) { return FHE.decrypt(balance[user]); }`. 6/ Tech stack: Builds on FHE libraries like TFHE-rs for Rust-based EVM execution. Supports OP Stack or Arbitrum Orbit for rollups, with privacy at the VM level. Developers can test via local nodes with encrypted state—thread links to a GitHub repo with setup instructions and a demo DEX. 7/ Broader context: This drops amid hot X chatter on Solana privacy (e.g., Light Protocol) and EVM L2s pushing confidentiality. Seismic aims for EVM chains like Optimism or Base, not Solana—focusing on Ethereum's 70%+ DeFi market share per DefiLlama. 8/ Challenges noted: FHE compute is gas-heavy (10-100x Ethereum today), but Seismic uses threshold decryption and optimistic verification to cut costs. Thread cites Zama's FHE benchmarks showing 50x improvements since 2024. Mainnet unclear—devnet teased "soon." 9/ Developer angle: "Write once, deploy privately anywhere EVM." Includes Hardhat plugins for FHE simulation. Links to docs detail migrating Uniswap V3 forks to private mode. Early testers report 90% code reuse from public contracts. 10/ Forward: Team plans devnet launch Q3 2026, with $5M seed from a16z Crypto scouts (unconfirmed in thread).
