Constants

This page collects the constants of Dango’s mainnet and testnet deployments: API endpoints, chain IDs, contract addresses, and the Hyperlane bridge contracts on EVM chains.

Endpoints

Each network runs two API servers: the Live API (consensus node — latest chain state, transaction broadcasting, real-time WebSocket) and the Archive API (archive node — structured historical data). See the API reference for which server serves what. Each server’s interactive documentation (Swagger UI) is at /docs/, with the raw OpenAPI spec at /openapi.json.

APINetworkHTTPWebSocket
LiveMainnethttps://api-mainnet.dango.zonewss://api-mainnet.dango.zone/ws
LiveTestnethttps://api-testnet.dango.zonewss://api-testnet.dango.zone/ws
ArchiveMainnethttps://api-archive-mainnet.dango.zone—
ArchiveTestnethttps://api-archive-testnet.dango.zone—

The GraphQL endpoint previously served at …/graphql on the same hosts is deprecated (see the API reference); prefer the REST + WebSocket surface above.

The testnet faucet is served separately at https://faucet-testnet.dango.zone/mint (see the API reference). There is no faucet on mainnet.

The code hash is the same on mainnet and testnet.

Hyperlane deployments

Dango bridges assets to and from EVM chains via Hyperlane warp routes. The tables below list the relevant contracts on each chain: Ethereum and Arbitrum serve Dango mainnet; Sepolia and Arbitrum Sepolia serve Dango testnet. The first three rows of each table are contracts deployed by other parties (Circle, Hyperlane), included for reference; the rest are deployed by us.

Ownership chain

The ownership structure is identical on every chain (except Arbitrum Sepolia, where an EOA fills the SafeProxy role, because the Safe frontend doesn’t support that chain):
