Abstract Wallet Guide: Bridge Your ETH Off Before Dec 15

What Abstract is and how it worked

Abstract launched on mainnet in January 2025 as a consumer chain from Igloo, the company behind Pudgy Penguins. It is built on the ZK Stack, the same technology as ZKsync Era, so batches of transactions are proven with zero-knowledge proofs and settled on Ethereum. Fees are paid in ETH, and the chain focused on games, NFTs, social apps and memecoins rather than heavy DeFi.

Its signature product was the Abstract Global Wallet, a smart contract wallet you could open with an email, social login or passkey instead of a recovery phrase. Many people used Abstract only through that wallet, and apps could sponsor their gas. That convenience matters now, because funds in an Abstract Global Wallet live at a different address from any wallet you control with a recovery phrase, and they need to be moved through that wallet.

Your Keylo address versus your Abstract Global Wallet

In Keylo, your Abstract address is a regular 0x account derived from your recovery phrase, the same address you have on Ethereum and every other EVM network. If you used Abstract with MetaMask or another phrase-based wallet, importing that phrase into Keylo shows the same first address and its Abstract balance.

An Abstract Global Wallet is different. It is a contract account controlled through your login, not through a 12-word phrase, so it cannot be imported into Keylo. If your funds are there, sign in to your Abstract Global Wallet and either bridge from it directly using Abstract's tools, or send the assets to your Keylo Abstract address and bridge from Keylo. Contract addresses on ZK Stack chains also differ from Ethereum, so never assume a smart wallet exists at the same address on another network.

Open your Abstract address in Keylo

1. 1

   Go to Keylo and create a wallet, or import the 12 or 24-word phrase from the wallet you used on Abstract.

2. 2

   Confirm your email and set a strong password. Your phrase is encrypted in your browser and never sent to Keylo in readable form.

3. 3

   Select Abstract in the network list and check the 0x address against the one you used before.

4. 4

   If the balance is empty, check whether your assets are actually in an Abstract Global Wallet or an app account.

5. 5

   Note your Ethereum, Base or Arbitrum balance too, since that is where your Abstract funds will go.

How to bridge ETH off Abstract with Keylo

Keylo's quotes come from LI.FI, which aggregates audited bridges and exchanges, and THORChain for native cross-chain swaps. If a cross-chain route cannot complete, the protocol refunds the sending wallet. As the shutdown approaches, bridge providers may drop Abstract; if no route appears for an asset, use Abstract's official tools instead. Do not wait to find out in December.

1. 1

   Open Swap and bridge in Keylo and choose Abstract as the source network.

2. 2

   Pick the asset, such as ETH or USDC, and choose the destination network, for example Ethereum, Base or Arbitrum. Your destination address is the same 0x address.

3. 3

   Review the quote: route, expected output, minimum received and every fee, including any small service fee.

4. 4

   Confirm and keep enough ETH on Abstract to pay the transaction fee.

5. 5

   Track the bridge in Keylo until it lands, then check the balance on the destination network.

Other ways out: the Migration Hub and native bridge

Abstract's Migration Hub is its main interface for the shutdown, and its native bridge withdraws to Ethereum through the chain's own contracts. Because Abstract is a ZK rollup, there is no week-long challenge period, but the native bridge adds an execution delay, quoted at a few hours and recently raised to as much as a day, before you can finalize on Ethereum. Both tools are web apps that connect to a browser wallet.

Abstract also pointed users to third-party bridges such as Stargate, Relay and Jumper. Whichever route you choose, send a small amount first, confirm it arrives, then move the rest. Keep some ETH on Ethereum if you use the native bridge, since finalizing there costs mainnet gas.

If you connect a browser wallet to these tools using the same recovery phrase you use in Keylo, the funds land at the same 0x address, and Keylo shows them on the destination network. Only install wallet extensions from their official sources, because fake extensions are one of the most common ways people lose funds during migrations.

Sending ETH on Abstract, and why not to receive new funds

Sending on Abstract is mainly useful for consolidating funds into one account before bridging. Do not ask anyone to pay you on Abstract now. If you must receive there, for example when an app returns funds, Keylo works as usual: open Abstract, tap Receive and share the address labeled Abstract, then bridge the funds out right away.

1. 1

   Open Abstract in Keylo and choose ETH or a token.

2. 2

   Paste the destination address or scan a QR code. Keylo checks the checksum and warns you about contract addresses.

3. 3

   Enter an amount or tap Max to keep ETH for the fee.

4. 4

   Pick a fee speed, review the network fee and exact amount, and confirm.

Fees on Abstract

Abstract uses the ZK Stack fee model, paid in ETH. You pay for computation and proving plus pubdata, the state changes published to Ethereum. Like ZKsync Era, Abstract charges the maximum a transaction might need and refunds unused gas, so the final fee is often below the estimate. Inside the Abstract Global Wallet, apps could sponsor fees through paymasters; from Keylo you pay normally from your ETH balance.

Keep a small ETH balance until you finish leaving. A wallet holding only tokens cannot bridge them, because the bridge transaction itself needs gas. If you are down to tokens only, ask someone to send a little ETH on Abstract, or move it from your Abstract Global Wallet first. Keylo shows the network fee before you confirm and adds nothing to normal sends.

Tokens and NFTs on Abstract

Keylo can show and send ERC-20 tokens on Abstract, but whether you can take a token with you depends on bridge and exchange support. ETH and major stablecoins have the most routes. Memecoins and app tokens that only trade on Abstract may have no route at all, so decide early whether to swap them into ETH or a stablecoin while liquidity still exists on Abstract.

NFTs and in-game items need their own plan. Some projects support moving collections to another chain; others do not. Check each project's official announcements, and expect that items with no migration path may lose access when the chain stops. Keep your own records of transactions for tax purposes, because explorers may not stay online.

Safety during the Abstract shutdown

• Move funds early; congestion and rushed decisions cause most mistakes.
• Use only migrate.abs.xyz, native-bridge.abs.xyz or reputable bridges you open yourself.
• Ignore DMs offering help with migration. Real support never asks for your phrase or login codes.
• Check where your funds actually are: Keylo address, Abstract Global Wallet or an app account.
• Send a test amount before every large bridge.
• Read how Keylo protects your wallet before importing any recovery phrase.
