Seismic

Seismic enables everyday developers to build encrypted DeFi. Seismic is an L1 blockchain capable of encrypting arbitrary smart contracts. Deploying a single Solidity contract is sufficient to launch an encrypted DeFi protocol, no custom infrastructure required. We achieved this by restructuring the modern blockchain stack around TEEs. This involved forking key components such as Solidity, Reth, and Foundry. By doing so, we were able to fully leverage the confidentiality guarantees of secure enclaves and eliminate the need for additional infrastructure. This architecture unlocks the three core properties necessary to encrypt arbitrary smart contracts: * **Encrypted global state.** Allows functions to operate on encrypted state owned by multiple users. Essential for use cases such as matching orders in a dark pool or liquidating encrypted margin positions in a lending protocol. * **Encrypted memory access.** Enables the modification of elements in a collection without revealing their locations in memory. Essential for use cases like placing bids in a blind auction and transferring money in a shielded pool. * **Encrypted orchestration.** Supports the consolidation of all protocol logic within a single VM. Without it, developers must split logic between transparent and encrypted components across different environments, introducing significant engineering complexity. These properties together restore powerful capabilities that are standard in vanilla DeFi, but notoriously difficult to achieve in encrypted environments. This is why developers building on Seismic can encrypt existing EVM contracts with minimal changes to the original.
