Ethereum R&D Stage migration has begun

The Ethereum balance snapshot we promised at the production-stage launch is done, and the migration of R&D-stage XRT is now live on-chain. Eligible holders can open the migration dApp, verify the balance credited to their address, and claim production XRT — with a +20% migration bonus — in a single transaction.

This post walks the whole thing end to end: what you are migrating to, why the snapshot looks the way it does, how the bonus works, the exact click-by-click flow, and — most importantly — how to verify the claim contract yourself before signing anything.

What you are migrating to

Production XRT lives on Polkadot — that is the only chain the network and every cloud subscription actually run on. The XRT you see on Ethereum is the bridged Polkadot production XRT: minted 1:1 against the Polkadot token via Snowbridge (https://app.snowbridge.network/send), and present on Ethereum exclusively to seed and sustain liquidity on Uniswap.

The migration hands you that new bridged production token directly on Ethereum, so you can hold it, bridge it to Polkadot, or trade it on the DEX immediately.

Why the snapshot, and what it covers

On February 5, 2026, the gas-based emission mechanism of the legacy XRT ERC-20 was exploited for free minting, crashing the Ethereum price ~80%. The Polkadot/Kusama production XRT was never affected — but to migrate the Ethereum side fairly, we needed a clean picture of who held what before the damage spread.

So the snapshot was taken at block 24,390,081 (Feb 5, ~12:00 UTC), covering a 24-hour window ending at block 24,397,281. It was reconstructed from The Graph subgraphs (Uniswap V2/V3/V4) and the Etherscan API, and published on IPFS for permanent, independent verification.

It is deliberately inclusive — direct holders, Uniswap liquidity providers, people who bought during the crash, and holders of legacy AIR / AIRA ID tokens are all counted as XRT for migration. Dev DAO balances were excluded before the snapshot, so none of those migrate.

Accept for +20%, or decline for the buyback

Every eligible address can do one of two things, exactly once:

• Accept — receive your full snapshot balance in production XRT, plus a 20% bonus. The bonus is funded by the 500,000 XRT migration bounty allocation from the production tokenomics — an incentive to migrate rather than take the buyback. You stay on board, holding production XRT.
• Decline — opt out of the token migration and into the buyback program instead. On-chain, your entitlement is routed to the Robonomics DAO payback address, and you forfeit the migrated XRT and its bonus. Declining is less “sell now” than a way of saying “this is enough for me, I’d like to step away” — and withdraw further support for the project.

What declining buys you is a claim to be bought back at the $2.20 reference price (the figure used for the valuation work, well above the $0.5–2 launch corridor). But read the terms plainly: it is paid out across a 12–36 month corridor, and only as and when the development treasury actually has the funds to honor it in time. It is a real, honored exit — everyone who chooses it gets paid — but a deliberately patient and conditional one.

That is the trade-off to weigh. Declining locks you to a fixed reference, far out and contingent on treasury timing. Accepting keeps your full balance plus 20% in a live, liquid, tradable token — with all of the upside (and risk) that holding through a thinly-traded production launch carries. For most holders, staying on board is the less patient and more open-ended of the two.

The choice is enforced by the contract itself, not by the front-end — see below.

Step by step

1. Open the dApp and verify eligibility

Go to the migration dApp and connect the wallet that held XRT at the snapshot. It reads your snapshot entitlement and shows the bonus-adjusted amount you will receive.

2. Accept and sign

Click Accept Migration. Your wallet pops up a single agree(...) transaction to the claim contract — review it and approve. Gas is the only ETH you spend; the XRT transfer itself carries no value transfer from you.

3. Confirmation on-chain

Once mined, the dApp confirms the migration and links the transaction on Etherscan.

The claim contract transfers the production XRT — your snapshot balance plus the 20% bonus — straight to your address. In the example above, that is the full 649.387710008 XRT landing in the wallet.

4. You now hold production XRT

The token is the live, bridged production XRT. Hold it, bridge it back to Polkadot via Snowbridge, or trade it on Uniswap right away — the direct ETH ↔ production-XRT swap:

https://app.uniswap.org/swap?chain=mainnet&inputCurrency=NATIVE&outputCurrency=0x1f752250f518e419f2f03804e25728c5c6dff73f

For this walkthrough I sold exactly 1 XRT — not because I’m in a hurry to leave, but just to prove the round-trip works end to end (it netted about $0.42, and yes, the gas cost more than the trade 🙂). The other 648 are staying right where they are.

Don’t trust — verify

The claim contract is open-source and short enough to read in a couple of minutes. Before you sign, check that the dApp talks to the contract below and nothing else.

• Claim contract (Ethereum mainnet): 0xB1b702972A022cca1aCfC0a64EcDFa6cd7899A2c
• Source & deployment: https://github.com/airalab/xrt-claim-contracts

The whole thing is a single Agreement contract. It holds the production XRT token address, the DAO payback address, and the snapshot Merkle root — all immutable, set once at deploy time:

// XRT Snowbridge token.
IERC20 public immutable XRT;        // 0x1F75…73f — production XRT
// Robonomics DAO multisig.
address public immutable PAYBACK;
// Snapshot merkle root.
bytes32 public immutable MERKLE_ROOT;

function agree(bytes32[] calldata merkleProof, uint256 amount) external {
    address holder = msg.sender;
    verifyProof(merkleProof, holder, amount);   // your address + amount must be in the snapshot
    amount += amount / 5;                        // +20% bonus
    XRT.safeTransfer(holder, amount);            // production XRT sent to you
    emit Agreed(holder, amount);
}

Three things worth confirming for yourself:

1. The XRT address is 0x1F75…73f — the production token from the launch post, not the deprecated legacy contract.
2. The +20% is literally amount += amount / 5 in code — it cannot be more or less than your snapshot entitlement plus a fifth.
3. Every claim is checked against the published snapshot Merkle root, and each address can only claim once (hasClaimed). There is no privileged mint, and the only admin function (transferOwned) is restricted to the DAO payback multisig.

Timeline

The Ethereum-side migration is open now, within the 12-month migration window. Any production XRT that holders never activate within that window gets burned. The Kusama-side migration runs immediately after the Kusama parachain is wound down — expected within the month — and will be covered in a separate post.

Where to ask for help

If you hit any snag during migration — a balance that looks off, a transaction that won’t confirm, or you’re simply unsure what to click — bring it to the XRT Traders chat on Telegram. As of today that is the single channel for token-related discussion:

https://t.me/xrt_trade

That separation is deliberate. Our social accounts and other community spaces stay focused on actually using Robonomics — setting up the devices we build, connecting smart homes, and growing the community of users. Mixing crypto and trading talk into those channels tends to push that audience away, so we keep token questions in their own dedicated chat. Different channels for different needs — and the XRT Traders chat is the right place for anything about the token itself.
