How long does it take to transfer eth from crypto.com to metamask

Minimum & Maximum Limits

Minimum withdrawal amount: Please check the Fees & Limits section in the app’s Settings, for the most current info on the minimum withdrawal amounts and fees, as they vary between different cryptos.

The maximum withdrawal limit for all cryptos is BTC 10 (or equivalent) on a 24-hour rolling basis. 

Withdrawal Addresses

There are no known issues with sending ETH and ERC-20 tokens to external addresses, as long as the wallet or exchange you are sending your tokens to supports the token you’re transferring. If you’re not sure if the ERC-20 token is supported by your wallet, please check with its developers first. 

In case no support is provided, start with sending the minimum amount possible. Only if the transaction is successful, proceed with sending the whole amount. While it may be more costly, it is definitely much safer – do remember, that once a transaction is posted to the blockchain, we will not be able to stop or reverse it. 

Automated Withdrawals

In most cases, ETH and ERC-20 withdrawals normally should take no longer than two hours to be processed.

Which cryptocurrency deposits are accepted in the Crypto.com App?

Trying to deposit a non-supported token may result in the loss of tokens.

Refer to this article for the list of supported cryptocurrency deposits. Always make sure that you are sending your cryptocurrency to the correct address, as crypto transactions are irreversible.

If you’re making your first deposit to your Crypto.com App, try sending a small amount of crypto first to familiarize yourself with the process and make sure that everything works correctly.

How to Deposit Crypto?

In the Crypto.com App: 

  1. Tap on the “Transfer” button > “Deposit” > “Crypto”

  2. Select the cryptocurrency you want to deposit 

  3. A pop-up will appear with your deposit address and its QR code. 

Please note

  • Your deposit address for ETH and ERC-20 tokens* is exactly the same.

  • XRP, BNB, EOS & XLM, ATOM, BAND, CRO(Native), STX, KAVA, RUNE, and LUNC deposits require both the destination tag/memo and deposit address.

  • A destination tag is referred to as Memo Text or Memo ID in Stellar (XLM) terminology.

  • Stellar (XLM) “account merge” transfers are not supported and are not considered deposits.  Merging XLM accounts to Crypto.com will result in your funds being unrecoverable.

In your External Wallet: 

1. Copy and paste the address to your crypto wallet (or scan the QR code) as the receiving address (you can also send it to yourself or your friends by tapping the Share button). 

2. Select the amount of crypto you want to deposit and submit/broadcast the transaction. Remember that to transfer ERC-20 tokens, you will need to have some ETH in your wallet to pay the transaction fees.

Where is My Crypto Deposit?

Once the transaction is on the blockchain, it will take the following number of confirmations for the deposit to appear in your Crypto.com App: 

  • 1 confirmation for XRP, XLM, ATOM, BNB, EOS, ALGO

  • 5 confirmations for NEO

  • 6 confirmations for BTC, BCH

  • 12 confirmations for LTC, VET, ETH, and ERC-20 tokens

  • 15 confirmations for ADA

  • 30 confirmations for XTZ

  • 4000 confirmations for ETHW

  • 40000 confirmations for ETC

When it does, you will receive an email notification about the successful deposit.

High gas prices can turn off even the most seasoned crypto user. Whether you’re a crypto native or a newcomer, one of the most efficient ways to utilize your assets is to bridge it to a Layer 2 network that inherits the security guarantees of Layer 1 Ethereum. 

Why? Low transaction fees, higher throughput, and a better overall user experience. You may even get exposure to certain dapps that aren’t available on Mainnet. 

To begin our bridging series, we’d like to start with the first well-structured, easy-to-use platform for Ethereum scaling and infrastructure development: Polygon’s Proof of Stake network (previously Matic).

Solving The Scaling Trilemma

The blockchain trilemma refers to a widely held belief that decentralized networks can only provide two of three benefits at any given time with respect to decentralization, security, and scalability (Gemini).

Matic was started as a scaling solution to overcome these obstacles.

Ethereum’s gas fees are untenable for most users and Polygon serves as a solution for the novel crypto user to purchase NFTs, partake in DeFi, and immerse themselves in virtual worlds in an efficient, affordable manner. 

Read on to learn how to bridge your assets to the platform using their native bridge and interact with a dapp that will make your environmentally friendly senses tingle. 🌲

Sending Assets To Polygon

First, you’ll want to make sure you have your funds handy in your wallet. MetaMask is your portal into the Web3 world and you can use it directly in your browser extension.

Remember to practice good security with your seed phrase—store it safely, in multiple places, and NEVER give it to anyone.

After you’re done, you can make your way over to Polygon’s bridge and approve the transaction to log into their wallet. It will look like this:

Signing in polygon

Click “Sign” and you will be directed to their bridging portal to transfer your assets from Ethereum Mainnet to Polygon.

Simply select which tokens you want to send, and click “Transfer”. It should take about 7-8 minutes to deposit your funds.

You will be prompted to sign and approve the transaction in your MetaMask wallet which is where the gas fee will also be quoted, and you will see a progress tab bar indicating when your transfer is complete.

Note that the Proof of Stake (PoS) bridge is secured by validators and will take approximately 3 hours when/if you want to move your funds back to Ethereum. 

Completed? Your funds are now on Polygon and you’ll be able to interact with a slew of dapps and tools.🕺🏽

Bridging Carbon Credits To Polygon

*this section originally appeared on James Beck’s article, How We Get To Negative Emissions With Web3

Web3 decentralizes financial primitives and protocols and makes it easier to collectively pool capital and increase liquidity. With smart contracts, rewards can be automated on-chain, in real time, which makes it easier to incentivize participation. Standardized, tradable carbon credits tokens increase liquidity, and because of open source software and the inherent composability of DeFi, projects can build upon other ideas and smart contracts.

One project that just began to standardize carbon credits as tokens is the Toucan Protocol, which built a “carbon bridge” to bring carbon credits to Polygon. Using the Toucan Protocol, anybody can tokenize their carbon offsets on the Verra registry and make them available to DeFi protocols. They plan on expanding to other carbon registries, like the Gold Standard in the future.

Users of the carbon bridge need to retire the carbon offsets in the “real world” before bringing them on-chain in order to guarantee that a carbon token is unique and that burning a token on-chain is equivalent to retiring an offset. Each of their Base Carbon Tonne (BCT) tokens is backed by 1 tonne of a retired CO2 credit.

Since launch on October 18th, already 10.8 million tons of CO2 have traversed the carbon bridge from the Verra registry and deposited in the Carbon Pool, BCT (Base Carbon Tonne). Incredibly, this is about 12% of NYC’s annual CO2 emissions.

Polygonscan BCT token

What is driving this rapid retirement of carbon credits? One clue is that members of KlimaDAO are retiring Verra credits and turning it to BCT in order to start earning rewards in a separate DeFi protocol called KlimaDAO.

$KLIMA tokens are fungible and backed by at least 1 Verified Carbon Unit in the KlimaDAO treasury. People can acquire KLIMA by depositing liquidity tokens (KLIMA/BCT and BCT/USDC) to the treasury, or directly from SushiSwap trading pools using the Polygon network. Holders of KLIMA can earn compounding interest on their KLIMA by staking, will have the ability to vote on Klima DAO policy. Staking encourages long-term holding of KLIMA, and allows participants to benefit from the rising price of carbon.

BCT Tokens On Polygon

Told you they’d be tingling.🌲 

If you want to harness the power of Web3 in climate servitude here’s how to get some BCT tokens on SushiSwap.

SushiSwap on Polygon

Once you’re on the Swap tab, make sure your network in the upper bar is selected to Polygon. If you’re on Mainnet, simply switch your network, and approve the transaction in MetaMask. 

You can then select which token you would like to swap and click “Approve Transaction”. In this case, we selected WETH. 

Approving SushiSwap transaction of WETH to BCT

You will have to approve the transaction fee on MetaMask (which will likely be close to $0), and “Confirm Swap” on SushiSwap for the final step:

And done! You pay a modest amount in gas fees and contribute to improving voluntary carbon markets. Feel free to continue perusing dapps on Polygon without high transaction costs barring the fun.

Final Thoughts

New users and natives alike don’t enjoy paying an arm and a leg in high gas fees, and as more and more dapps get deployed on Polygon, people may conduct most of their Web3 activity in this ecosystem. Polygon’s Proof of Stake network is more environmentally-friendly than Ethererum’s current Proof of Work chain (soon to change) and allows Ethereum activity to scale in an efficient way. Once your assets are bridged, you can choose to swap and stake tokens, play games, purchase NFTs, and foray more into Web3 with ease.
