Sei

aid: sei
name: Sei
description: Sei is a high-performance Layer 1 blockchain optimized for trading and decentralized exchange (DEX) applications.
  It is the first parallelized EVM blockchain, delivering sub-second block times (~400ms), 100 MGas/s throughput, and full
  Ethereum compatibility without code changes. Sei combines Twin Turbo Consensus, a parallelization engine, and SeiDB to eliminate
  traditional performance bottlenecks. Developers can interact with Sei through EVM JSON-RPC endpoints (Ethereum-compatible)
  and Cosmos REST/LCD endpoints for querying markets, orders, accounts, staking, governance, and DEX state on the pacific-1
  mainnet and atlantic-2 testnet networks.

  name: Sei EVM JSON-RPC API
  description: Ethereum-compatible JSON-RPC API for interacting with Sei's EVM layer. Supports standard Ethereum methods for
    sending transactions, querying account balances and code, retrieving block and transaction data, managing log filters,
    estimating gas, and tracing transaction execution. Also includes Sei-specific extensions for cross-VM address resolution
    and synthetic transaction lookups. The public mainnet endpoint is rate-limited to 15 requests per second; dedicated endpoints
    are available through infrastructure providers for production workloads.
