Miden testnet tokens

Tokens on Miden (chain ID 999999999) are fungible faucet accounts and use 6 decimals (not 18). The faucet account ID below is the token identifier used in intents. Mint them to your Miden account via the User Dashboard faucets tab. Account IDs are accepted in hex (0x…) or bech32 (mtst1…) form.

Discovering chains and tokens in code

import { mainnetGraph, testnetGraph } from "@epoch-protocol/epoch-intents-sdk";

// Pick graph by chainId (mainnet vs testnet)
// getTokensForChain(chainId) → { symbol, address, decimals }[]
// getChainsFromGraph(chainId) → destination chain options

See SDK Integration Guide and compact-demo-epoch for full patterns.

---

Requesting new chains or tokens

The public mainnet set above covers Base, Arbitrum, Polygon, Optimism and the tokens USDC, USDT, WETH, and DAI. For anything beyond that, contact the Epoch team or on Telegram with:

• Chain name and chain ID

• Token contract addresses and decimals

• Use case (swap, bridge, protocol interaction)

New entries are added to Epoch's routing graph after validation.
