Move assets across Polkadot, Astar, Soneium & Ethereum
Native XCM transfers between Polkadot Asset Hub, Polkadot Hub EVM and Astar — real DOT, USDt and USDC, never wrapped IOUs. Routes to Soneium and Ethereum go through the official bridges.

How it works
Polkadot Asset Hub and Polkadot Hub EVM are one chain with two doors. Astar is a sibling parachain connected by XCM.
Asset Hub ⇄ Hub EVM
Every 0x address has an Asset Hub twin (the address followed by twelve EE bytes). Sending to Hub EVM is a plain transfer to that twin; coming back uses the XCM precompile at 0x…0a0000. Tokens appear in MetaMask as ERC20 precompiles, e.g. USDt at 0x000007C0…01200000.
Polkadot ⇄ Astar
Asset Hub is the reserve for DOT, USDt and USDC. Going to Astar is an XCM reserve transfer; coming back uses Astar's XCM pallets. Destination fees (≈0.0001 DOT or ≈0.0002 USDt on Astar) are taken from the amount.
Soneium & Ethereum
Ethereum assets reach Polkadot through Snowbridge and then move into Hub EVM here. ASTR reaches Soneium through Chainlink CCIP on the Astar Portal. The Portal points you to the right bridge and completes the Polkadot side.
FAQ
Which wallet do I need?
For Asset Hub and Astar use Talisman, SubWallet, Nova Wallet or Polkadot.js. For Polkadot Hub EVM use MetaMask (Talisman and SubWallet also work as EVM wallets). Asset Hub ⇄ Hub EVM needs the wallet of the side you send from.
What is "Map account" and do I need it?
A Polkadot account that wants to use EVM apps directly (sign in MetaMask-style dApps with the same key) calls revive.mapAccount once. It links your native account to its 0x address and takes a small refundable deposit. You do not need it to receive funds on a MetaMask address — the Portal sends to the right account automatically.
Can I deposit DOT from an exchange straight to my MetaMask address?
Yes. Exchanges only support Polkadot (SS58) addresses, so use the "Asset Hub deposit address" shown under your EVM wallet. Funds sent there show up in MetaMask on Polkadot Hub.
Why can't I bridge ASTR to Polkadot Hub?
ASTR is not registered as a foreign asset on Polkadot Asset Hub yet, so Asset Hub cannot hold it. Registration has to be proposed by Astar over XCM. As soon as it exists it becomes one line in portal-config.js. Until then, ASTR moves to Soneium via CCIP.
Why did I receive slightly less than I sent?
Cross-chain transfers pay execution on the destination in the asset itself: about 0.0001 DOT on Astar, about 0.0008 DOT on Asset Hub, a fraction of a cent for USDt/USDC. Same-chain moves between Asset Hub and Hub EVM have no destination fee.
