Sei chain ID 1329 and mainnet RPC URL

Source snapshotJuly 4, 2026

Source evidence snapshot July 4, 2026. Sei publishes EVM network information for mainnet. Sei documentation lists chain ID 1329, the official EVM RPC URL, and mainnet explorer links.

Current Sei network fieldsCopy the chain ID, RPC URL, and explorer here, then check the source and probe status. For step-by-step setup, use the wallet setup guide. For production cautions, review public RPC safety.

Quick settings

Sei RPC status and chain ID answer

Sei mainnet uses chain ID 1329 / 0x531, RPC URL https://evm-rpc.sei-apis.com, explorer https://seiscan.io, and SEI as the gas token. Use the latest source check and linked docs to verify the fields before adding the network to a wallet, script, or app.

Chain ID: 1329 / 0x531
RPC URL: https://evm-rpc.sei-apis.com
Explorer: https://seiscan.io
Gas token: SEI

Copy Sei config Open source docs Explorer directory Gas token directory

Good fit when you need:

the Sei chain ID, RPC URL, explorer, and gas token in one place;
source documentation links beside the copied setup fields;
manual wallet config fields without connecting a wallet or choosing an RPC provider.

Before you paste these fields:

compare the chain ID against the source link on this page;
open the explorer once and confirm it matches the network you expect;
use the public RPC for setup checks, then choose monitored infrastructure for production traffic.

Verification record

Automated source snapshots and recorded probe evidence are tracked separately. The source snapshot timestamp is not a manual review date. This is not a live uptime, latency, or production reliability monitor. If a recorded public RPC probe fails, verify the source links and current endpoint availability before changing production configuration.

Sei wallet-add fields

Wallet directory sites often expose a connect button. Main.net keeps the same MetaMask and EIP-3085 setup fields as text so developers can compare them with official/source docs before calling wallet_addEthereumChain.

Monitoring evidence

These checks are review signals only. They are not uptime, latency, privacy, or production reliability claims. A source fetch failure or eth_chainId failure can mean a source page or public RPC endpoint was unavailable, changed, or rate-limited during a check. Re-open source links and test current RPC availability before relying on a public endpoint.

curl eth_chainId check

Minimal JSON-RPC identity check. This verifies the endpoint-reported chain ID only, not uptime or production suitability.

curl -s -X POST \
  -H 'content-type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}' \
  https://evm-rpc.sei-apis.com

# Expected chain ID: 1329 / 0x531

Developer signals

External dashboards a developer may inspect before choosing where to deploy. Main.net links to these references but does not collect the metric values, normalize methodologies, rank chains, or recommend deployments.

Main.net links to external developer-signal dashboards but does not collect, normalize, rank, or republish their metric values in this version.
External metrics can use different methodologies and update schedules. Check the linked provider documentation before comparing chains.
These links are not recommendations, rankings, investment advice, or claims that a chain is suitable for a specific application.

Safety note

Sei documentation notes that public endpoints have rate limits. Production apps should consider a dedicated RPC provider or running their own node.

Main.net is an independent reference site. It does not operate this chain, custody assets, execute transactions, or provide investment advice.
