Send exactly to:
This asset needs a memo / tag. Send it with or the exchanger cannot credit your deposit.
You receive about at . Exchange reference .
Status: waiting for your deposit
You send from your own wallet straight to the exchanger — nothing to connect, no account, and you stay on this page throughout. Rates are indicative until a swap is opened.
The swap is carried out by an independent exchanger and the deposit address above is theirs. mycoin.hk never holds, receives or controls your funds, has no key to that address, and earns a referral commission. Opening a swap sends your receiving address, IP, browser and timezone to the exchanger for their compliance checks; we store none of it. Check their terms, fees and country restrictions before sending anything.
Scroll and Linea are both zero-knowledge rollups that use validity proofs to settle transactions on Ethereum, but their prover architectures differ fundamentally, leading to distinct cost profiles. Scroll uses a modular, open-source prover that can be run by anyone, while Linea relies on a centraliz
Your MetaMask is probably not broken, and the tokens are not lost. When a wallet shows the wrong token balance on Base, the cause is almost always a mismatch between what MetaMask thinks you hold and what the Base network actually says you hold. The fix usually comes down to adding the correct token
A validity proof is a cryptographic proof that a transaction batch on a Layer 2 network was computed correctly, submitted alongside the batch data itself. A fraud proof, in contrast, is a challenge submitted after a transaction batch to show that it was computed incorrectly, relying on a period duri
The short answer: you read a rollup transaction on a block explorer by understanding that most of what you see is a batch of compressed data posted to the L1 chain, not a line-by-line record of individual user actions. L2 block explorers decode this data for you, but knowing what sits behind the num

The present mycoin.hk is an independent cryptocurrency information site focused on Layer 2 networks, cross-chain transfers and practical wallet safety. It is not the Hong Kong bitcoin investment platform that used this domain in 2014 and 2015, is not connected to that platform's operators, and does not continue any former investment programme.
The domain's history is disclosed because readers searching for the old MyCoin name should not have to guess whether the two sites are related. Facts.hk has assembled 30 documented facts about the MyCoin case from Hong Kong government records and contemporaneous reporting. The record distinguishes the widely reported HK$3 billion estimate from the HK$180 million attached to police reports by March 2015, and it distinguishes allegations and arrests from findings of guilt.
Everything else on this site concerns current cryptocurrency technology. Nothing here provides access to an old MyCoin account, recovers funds, or represents the former business.
Your trade happens inside the exchange's own ledger. Nothing touches the blockchain until you withdraw.
You swap from your own wallet. The transaction settles on the chain and you pay its fee.
Not financial advice. mycoin.hk publishes market data and general information about digital assets. Crypto assets are volatile and you can lose everything you put in. Nothing here is a recommendation to buy, sell or hold, and we make no price predictions.
Prices are sourced from third parties and may be delayed or wrong. Verify anything you intend to act on against a primary source.
