SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Sei provides a parallel EVM layer with native Cosmos interop, enabling Ethereum-compatible contracts to run efficiently on Sei while accessing Cosmos features through precompiles and pointer contracts.

Core Features & Use Cases

  • Parallel EVM execution with SeiDB for deterministic cross-transaction outcomes.
  • Cosmos interoperability through pointer contracts, precompiles for staking, governance, IBC, and JSON parsing.
  • Use cases include DeFi protocols, cross-chain dApps, and Cosmos-native token workflows without changing Solidity code.

Quick Start

Deploy a sample contract on Sei using Paris EVM settings and verify it on Seitrace.

FAQPage Schema
How do I run Ethereum-compatible smart contracts on Sei's parallel EVM?▼

To run Ethereum-compatible smart contracts on Sei's parallel EVM, configure the Paris EVM target settings for deterministic cross-transaction outcomes and verify execution using Seitrace.

Does my Solidity code need changes to access Cosmos interoperability features?▼

No, Solidity code requires no changes to access Cosmos interoperability. Sei uses precompiles and pointer contracts to enable native staking, governance, and IBC interactions directly.

What are pointer contracts and how do they handle Cosmos balances?▼

Pointer contracts are Sei EVM mechanisms that map and manage Cosmos-native token balances across networks, enabling cross-chain dApp workflows and associated balances without altering Solidity code.

How do I ensure deterministic results during parallel EVM execution?▼

To ensure deterministic results during parallel EVM execution on Sei, configure the Paris EVM target correctly and rely on SeiDB to manage deterministic cross-transaction outcomes.

Can I use Sei precompiles for staking and IBC transfers?▼

Yes, Sei precompiles support staking, governance, IBC transfers, and JSON parsing, allowing Ethereum-compatible contracts to interact seamlessly with underlying Cosmos network features.

What are the limitations of building DeFi protocols on a parallel EVM?▼

When building DeFi protocols on Sei's parallel EVM, limitations include the strict requirement for proper Paris EVM target configuration to avoid non-deterministic cross-transaction outcomes.
