# Seistream — Sei blockchain explorer

> Seistream is the multi-chain block explorer for the Sei network
> (mainnet `pacific-1`). It indexes both the Cosmos SDK side and the
> Sei EVM, surfacing blocks, transactions, accounts, contracts,
> validators, governance proposals and IBC activity through a web UI
> and a public JSON API.

If you are an agent fetching data programmatically: **prefer the JSON
API at `https://api.seistream.app/api/v2/*` over scraping the HTML.**
The API is documented at <https://api.seistream.app/swagger> and
returns the same data the UI renders. Skipping HTML parsing reduces
load on the site and gives you a stable schema.

A more detailed surface description is in [llms-full.txt](https://seistream.app/llms-full.txt).

## Pages

- [Home](https://seistream.app/): live blocks + tx feed, top stats.
- [Blockchain](https://seistream.app/blockchain): chain-wide metrics
  (block time, tx throughput, fee burn, supply).
- [Blocks](https://seistream.app/blocks/[height]): one block, both its
  Cosmos and EVM views.
- [Transactions](https://seistream.app/transactions/[hash]): one tx,
  Cosmos hash (64 hex, no `0x`) or EVM hash (66 hex, `0x` prefix).
- [Account](https://seistream.app/account/[address]): EOA / contract.
  Accepts `sei1…` bech32 or `0x…` hex; both resolve to the same entity
  on Sei.
- [Contracts](https://seistream.app/contracts/[address]): verified
  source, ABI, bytecode, proxy implementation.
- [Tokens](https://seistream.app/tokens/[denom]): ERC-20 / ERC-721 /
  CW-20 / CW-721 / IBC / native — same page handles all six.
- [Validators](https://seistream.app/validators): active set, voting
  power, commission, uptime.
- [Proposals](https://seistream.app/proposals/[id]): governance, votes,
  tally, deposits.
- [Relayers](https://seistream.app/relayers): IBC channel + relayer ops.
- [Codes](https://seistream.app/codes/[id]): CosmWasm code entries.
- [Utilities](https://seistream.app/utilities): converters (denom,
  address, hash format).
- [Labs](https://seistream.app/labs): experimental views (tx mock UI,
  graphics).
- [API documentation](https://seistream.app/api): JSON API reference
  embedded in the UI.

## Public APIs

- [v2 OpenAPI (Swagger)](https://api.seistream.app/swagger)
- [v2 base](https://api.seistream.app/api/v2)
- [Search endpoint](https://api.seistream.app/api/v2/search?query=)

## MCP (for AI tooling)

An MCP server exposing the explorer as tools is at
<https://mcp.seistream.app/mcp> (streamable HTTP). Configure your MCP
client with `{ "mcpServers": { "seistream": { "url": "https://mcp.seistream.app/mcp" } } }`.
