What is the MOVR contract on Base?

Moonbeam’s official migration announcement publishes 0x43fEB74608334DDa8c1a6500D185cFC3Ea962B83 as the Base MOVR contract. Verify both the address and the Base network before swapping.

Do I need MOVR or ETH for Base gas?

Base uses ETH for gas. MOVR on Base is an ERC-20 token and does not replace the ETH balance needed for a normal transaction.

Can I swap ETH or USDC for MOVR on Base?

Use a supported source token and request a current quote. The exact token, source network and amount determine whether a route is available; this guide does not guarantee every pair.

Is Base MOVR the same balance as native MOVR on Moonriver?

No. They are balances on different networks. The announced 1:1 migration linked the representations but did not merge their wallet balances automatically.

Does this purchase migrate my old Moonriver assets?

No. A new swap into Base MOVR is separate from the legacy migration process and its 31 July 2026 deadline. Use current official guidance for an old holding.

Can I buy MOVR in Sweep with a bank card?

This guide covers exchanging existing crypto. A card or bank purchase requires a separate fiat on-ramp before using the crypto-to-crypto flow.

How to buy MOVR on Base

Get MOVR on Base by exchanging crypto you already hold. Choose a supported source asset, select the verified MOVR token on Base, and review the route in Sweep before approving.

Your supported crypto

MOVRBase

Continue in Sweep

Check that Sweep lists this exact token contract and offers a current route. A matching ticker alone is not enough.

Base: quick answer

Choose Base as the destination and MOVR as the token to receive. Verify the contract against the current Moonbeam reference, enter your amount and review the available quote. This is a crypto-to-crypto flow; buying with a card or bank account is a separate on-ramp step.
Use the exact contract only if it is listed by the current provider selector and a route is available.

Choose the MOVR token on Base

Moonbeam announced a 1:1 MOVR migration to Base in July 2026. MOVR on Base is an ERC-20 token, separate from a native MOVR balance on the former Moonriver network.

Verify the destination contract rather than selecting by ticker or logo alone. Use the full address in the token facts above, and confirm that the route ends on Base.

Check current token and route support

In Sweep, select the exact network and token contract. Continue only if that asset is listed and the app returns a current route for your amount. This guide does not guarantee current token liquidity or support for every source asset.

Swap on Base or bridge from another network

If your source tokens are already on Base, the available route may be a same-network swap. Tokens on another network need a route that actually delivers MOVR to Base.

Availability depends on the source token, amount, provider support and current liquidity. A missing route is not a reason to choose a namesake contract. Try a supported source asset or review another amount in the app.

Review fees and leave ETH for gas

Review the final received amount together with source-network gas, any approval, bridge or provider costs, and any app fee. A displayed estimate can change before execution.

Base uses ETH for transaction fees. Buying MOVR does not necessarily leave you with enough ETH for the next transfer or contract interaction. Check both balances after the swap.

Check the received balance

Switch your wallet to Base and inspect the completed route and recipient. If MOVR is missing from the wallet’s token list, use the verified contract to display the existing balance.

Buying current Base MOVR is different from migrating an old Moonriver holding. The original migration had a 31 July 2026 deadline; do not assume that an old balance moves automatically when you make a new purchase.
