How to Move Your dApp from Ethereum to Velas in 2026

Velas is an EVM-compatible chain. For an Ethereum dApp, that means you can often reuse your Solidity contracts, wallet flows and much of your front-end code instead of building a new product from scratch. The move is still a real migration, though. Your contracts get new addresses, your users' balances and positions stay on Ethereum until they move, and your integrations need to point at the new network.

Before you start, decide what you are moving. A simple token-based app, a lending market, a DEX pool and a governance system each carry different risks. Write down every contract, every token it depends on, every off-chain service (such as indexers, price feeds, notification bots and admin scripts) and every place where users must approve a transaction.

Then decide your goal. Some teams move completely and retire the Ethereum version. Others launch a second deployment and let users choose. A third option is a limited pilot with capped deposits. Each choice affects how you message users, how you handle liquidity, and how much testing you need.

The tradeoffs are worth stating clearly to your community. A new chain can offer different user bases, fee levels and tooling, but it also brings different liquidity depth, bridge dependencies and support load. Speed and low fees are not guarantees, so measure them yourself on the network you use.

EVM compatibility is the foundation of this guide, but compatible does not mean identical. Before you deploy anything, review your contracts against the checks below and against Velas's current technical documentation.

• Compiler version: confirm which Solidity versions and EVM targets the chain supports, and match your build settings.
• Opcodes and precompiles: look for any calls to Ethereum-specific precompiles, block properties or gas assumptions.
• Block time and finality: review any logic that depends on block numbers as a clock, such as vesting or interest accrual.
• Oracles: check which price feeds and oracle providers are available on Velas, since many Ethereum feeds are not deployed everywhere.
• Token standards: confirm that ERC-20 and other standards you rely on behave the same way for the assets you plan to use.
• Gas and fee handling: remove hard-coded gas limits and test how your app behaves when fees change.

A simple comparison table helps the team agree on the result:

Area	Ethereum version	Velas version	Status
Compiler and EVM target	Current build	To confirm	Pending
Oracles	Existing feeds	To confirm	Pending
Bridges for your tokens	Existing routes	To confirm	Pending

Fill in the right column from official documentation and your own test results. Do not assume support because a competitor or a generic guide lists a chain as EVM-compatible.

Every EVM chain has a small set of settings that wallets and tools need: a network name, RPC URL, chain ID, currency symbol and block explorer. Getting any one of these wrong can cause users to send funds to the wrong network or cause your app to read data from a stale or malicious endpoint.

Use the settings published by Velas in its official documentation or on its official channels. Compare them across at least two sources you trust. Be wary of settings shared by unknown accounts, pasted into comments, or included in ads, and never accept a request to replace a network setting inside your own app without checking it yourself.

After you confirm the values, test them in a wallet you control. Add the network manually, check that the chain ID matches the documentation, and confirm that the block explorer shows the blocks you expect. Then record the values in a single configuration file that your front end, scripts and monitoring tools all read from.

This single source of truth matters later. If Velas changes an endpoint, you want to update one place and redeploy, not hunt through several repositories while users are already on the site.

Do not deploy to a live Velas environment until your contracts have passed tests on a test network. Start with your existing Ethereum test suite. Run it against a local development node or a test environment, and fix any failures that come from differences in gas, block time or chain behaviour.

Next, deploy to the test network and run end-to-end flows. Test every user action that moves value: deposits, withdrawals, swaps, borrowing, liquidations, claims and emergency pauses. Include edge cases such as zero balances, failed transfers, expired approvals and oracle outages.

Use a checklist so the team can track progress:

1. Unit tests pass with the Velas compiler settings.
2. Integration tests pass against the test deployment.
3. Oracle and price feed calls return sensible values.
4. Admin functions require the correct roles and multisig approvals.
5. Pause and recovery procedures have been rehearsed.
6. A third party has reviewed the contracts and the deployment scripts.

If you change any contract to fit the new chain, treat the changed version as new code. Rerun the full test suite and review the diff. Changes made in a hurry are one of the most common sources of avoidable failures during migrations.

Once testing is complete, deploy the contracts in a fixed order. Deploy libraries and base contracts first, then the main contracts, then the configuration that links them. Record every address in your configuration file and in a public changelog so users and integrators can verify them.

Verify the source code on the Velas block explorer, if the explorer supports verification for your compiler setup. Verified source lets users read what the contract does before they interact with it. Publish the exact compiler version, optimisation settings and constructor arguments with the verification.

Transfer ownership and admin rights carefully. Deployer keys should not remain the owner of production contracts. Move ownership to a multisig wallet that requires several signers, and test that the multisig can perform the admin tasks you need before you finish the transfer.

Finally, set initial parameters on purpose. Review fees, collateral ratios, caps, rate models and whitelisted tokens. Start with conservative limits. You can raise them later after monitoring real usage, which is safer than launching with values copied from Ethereum that may not suit the new environment.

Users and liquidity are the hardest part of any chain migration. Your Ethereum deployment will still hold funds, and those users need a clear, safe way to move or to stop using the old version.

Start by listing every asset and position. For each one, decide whether users should withdraw and redeposit, bridge their tokens, or stay on Ethereum. Some protocols can offer a migration contract that closes a position on one chain and opens an equivalent one on the other. Build such tools only after careful review, because they touch user funds directly.

To bootstrap liquidity on Velas, teams often add pools or markets using their own treasury assets. Be cautious with incentive programmes. Any rewards should be disclosed, time-limited and sized so that the project does not depend on temporary emissions. Do not promise specific returns, and avoid language that suggests a token or yield is guaranteed.

Keep the Ethereum version running with clear status notices until most funds have moved. Announce a date for any shutdown, state what will happen to remaining positions, and explain how users can withdraw. Abrupt closures damage trust and can create support emergencies.

Bridges are where many cross-chain losses happen, so treat bridging as a high-risk step. Choose routes deliberately rather than clicking the first option a search engine returns.

For each token, check whether a bridge supports Velas and which version of the token it moves. A bridged token may be a wrapped representation rather than the original. Some bridges use lock-and-mint designs, others use liquidity pools, and others use messaging protocols that rely on external verifiers. Each design has its own trust assumptions and failure modes.

A cautious process looks like this:

• Read the bridge's own documentation on supported assets, fees, delays and limits.
• Send a small test transfer first and confirm it arrives correctly.
• Check the token contract address on the destination chain against the official project announcement.
• Keep transaction hashes and receipts.
• Be ready to wait. Some transfers take longer than expected.

When you direct users to bridges, do not claim that a route is safe or endorsed unless you have verified it. Describe what each option does, state its known risks, and remind users that bridges can be paused or exploited. Bridges such as Across and LayerZero-based routes are examples of the kinds of tools to review, but you must confirm their current Velas support yourself.

Once the contracts are live, the rest of your stack must point at Velas. Update every front end, script, bot and integration. A single hard-coded Ethereum endpoint can break an entire user flow.

Start with the front end. Load network settings from your configuration file, handle the case where a user's wallet is on the wrong network, and prompt them to switch networks in a clear way. Show the correct contract addresses and make sure transaction messages name the network being used.

Next, update indexers and data services. If you read events from your contracts, point your indexer at the Velas deployment and confirm it backfills the correct block range. Dashboards, analytics and support tools need the same update.

Finally, check third-party integrations. Price oracles, wallets, custody providers, exchanges that list your token and analytics sites may each need separate support for Velas. Make a list, contact each provider through its official channel, and confirm support before you announce the launch. Never rely on an unsolicited message offering to list your token or add your app, since those are a common source of scams.

Most migration problems are predictable. Knowing them in advance saves time and protects users.

The first is wrong network settings. Users who add a fake or outdated network can end up on a different chain or sign transactions against the wrong contracts. Show the verified settings on your site and keep them consistent everywhere.

The second is approval risk. Users who approved an Ethereum contract may still have token allowances open. Encourage users to review and revoke old approvals using a reputable approval-checking tool, and remind them that revoking is a normal security step.

The third is phishing. Migration announcements attract fake support accounts, fake airdrops and fake bridge sites. Publish your official links only in places you control, and tell users that you will never ask for seed phrases, private keys or wallet signatures to fix a problem.

The fourth is underestimating support. Expect confused users, failed bridges and questions about balances. Prepare FAQs, a support process and a status page before launch.

The fifth is copying Ethereum parameters without review. Gas costs, oracle behaviour and liquidity depth may differ, so reassess every parameter after launch.

Use this checklist before you announce that the Velas deployment is live:

1. All contract addresses are published, verified and recorded in your changelog.
2. Admin rights sit with a multisig, and signers have tested it.
3. Network settings on your site match the official Velas documentation.
4. Oracles, bridges and third-party services are confirmed for Velas.
5. Caps and limits are conservative for the first phase.
6. Support materials, status pages and official contact channels are ready.
7. You have a written plan for pausing the app or redirecting users if a serious issue appears.

After launch, monitor the deployment closely. Watch transaction failures, unusual withdrawals, oracle deviations and gas spikes. Set alerts for admin actions. Review the data weekly for the first few months and adjust parameters in small steps.

Keep your public updates factual. Report what changed, what you found and what users should do next. Avoid predicting prices or yields, and avoid describing the migration as an investment opportunity. Migrations succeed when users can see clearly what is happening and why.

Treat this guide as a starting point rather than a final specification. Velas's documentation, the tools you use and the assets you move will all change, so confirm each step against current official sources before you act.
