Blockchain.com
0.0Blockchain.com: crypto brokerage, self-custody wallet, and explorer Blockchain.com is one of the oldest companies in crypto. It began in 2011 as a Bitcoin block explorer and now offers a custodial trading account, a self-custody DeFi Wallet, an exchange, the Explorer, and rewards products. It is headquartered in London, with a US headquarters in Dallas since November 2025. What it is Blockchain.com combines two different kinds of product in one app, and it matters which one you use: Trading account (custodial): Blockchain.com holds your crypto for you. You can buy, sell, and convert with a bank card or bank transfer, and support can help with account access. In return you trust the company with your funds, and identity verification is required. DeFi Wallet (self-custody): you hold the keys through a recovery phrase. Blockchain.com cannot access or recover your funds. The DeFi Wallet connects to decentralized apps and, since 2026, offers perpetual futures through Hyperliquid and funding by card, Apple Pay, and Google Pay. Key features Buy and sell: purchase crypto with a card or bank transfer in supported countries. Exchange: an order-book exchange at exchange.blockchain.com for more active traders. Rewards: earn products, including fixed-term rewards, on some assets. Rates vary and are not guaranteed, and custodial rewards carry company risk. Explorer: the public block explorer for Bitcoin, Ethereum, and other chains, free to use without an account. Institutional services: custody and staking for businesses. Learning portal: beginner guides on crypto basics. Costs and risks Buying through the trading account usually includes a spread on top of any card or bank fee, so the price you pay can be higher than the market rate shown elsewhere. Network fees apply when you withdraw to an outside wallet. Products such as perpetual futures in the DeFi Wallet use leverage, which can lose more than a small price move would suggest and can lead to liquidation. Rewards products pay variable rates that depend on market conditions. Check the fee summary on each screen before you confirm, and start with small amounts while you learn how each product works. Regulation and company Blockchain.com holds a MiCA licence from Malta's financial regulator, granted in October 2025, covering custody, brokerage, and wallet services across the European Economic Area. Products and features vary by country. Some services are not available in the United States or other regions. In 2026 the company filed confidentially for a US public listing. That does not change how the app works for users. Security Account protection: PIN, biometric login, and two-factor authentication. Use an authenticator app rather than SMS where possible. Back up the DeFi Wallet: write down its recovery phrase offline. If you lose it, Blockchain.com cannot restore that wallet. Know the difference: assets in the trading account are custodial. For long-term holdings you may prefer the DeFi Wallet or a hardware wallet. Phishing: Blockchain.com users are frequent phishing targets. Log in only at blockchain.com, and never share your recovery phrase or 2FA codes. How to get started Download the Blockchain.com app or go to blockchain.com. Sign up with your email, set a strong password, and turn on two-factor authentication. Complete identity verification if you want to use the trading account. Create the DeFi Wallet separately if you want self-custody, and back up its recovery phrase. Use the Explorer to check transactions on public blockchains. Vaulta relevance We found no sign that Blockchain.com supports Vaulta (A) in its trading account or DeFi Wallet. Vaulta users should use a Vaulta wallet such as Anchor, and an exchange that lists A, to move funds in and out. Pros and cons Pros Long history and a well-known free block explorer. Choice of custodial and self-custody products in one app. Regulated in the EU under MiCA. Beginner-friendly buying and selling. Cons The trading account is custodial and requires identity verification. Card purchases and spreads can be costly. Features differ by country, and some are high risk, such as leveraged perpetual futures. No Vaulta (A) support. FAQ Is Blockchain.com a wallet or an exchange? Both. It offers a custodial trading account, a self-custody DeFi Wallet, and an exchange. Does Blockchain.com hold my keys? For the trading account, yes. For the DeFi Wallet, no: you hold the recovery phrase. Can I use the Explorer without an account? Yes. The Explorer is public and free. This listing is informational and is not financial advice.

SimpleSwap
0.0SimpleSwap: instant crypto exchange without sign-up SimpleSwap is an instant cryptocurrency exchange service that has operated since 2018. You pick two coins, send the deposit, and receive the other coin at an address you choose. No account is needed for a standard swap, and SimpleSwap does not hold a balance for you. It also offers a fiat-to-crypto purchase option through a payment partner. SimpleSwap supports Vaulta (A), the token that replaced EOS. What it is SimpleSwap is a swap aggregator rather than an order-book exchange. It sources rates from liquidity providers and handles the conversion on your behalf. That makes it simple to use, but it also means you are trusting SimpleSwap and its partners with your funds while a swap is in progress, and compliance checks can pause a swap. It is available on the web and as mobile apps for iOS and Android, plus a direct Android APK download. Key features Large coin list: SimpleSwap says it supports more than 2,800 cryptocurrencies. No sign-up for swaps: an optional account adds history and loyalty features, but it is not required. Fixed or floating rate: a fixed rate is locked for about 20 minutes, and a deposit that arrives late may be refunded or filled at a new rate. A floating rate is an estimate that can move while the swap completes. Buy with a card: purchase around 30 coins with Visa or Mastercard through Mercuryo. The SimpleSwap FAQ lists a Mercuryo fee of about 3.95% plus a SimpleSwap fee of 1%. Card purchases go through Mercuryo's own verification. Loyalty program: the SimpleSwap Coin (SWAP) is used as the internal currency for the loyalty program, with benefits such as cashback for active users. Support: live chat and email support. Vaulta (A) support SimpleSwap lists Vaulta (A) on the Vaulta blockchain. The old EOS listing is marked as delisted, so search for Vaulta or A rather than EOS. When sending A to a Vaulta exchange account or receiving it, always check whether a memo is required, since a missing memo is a common cause of lost or delayed deposits. Security, KYC, and availability Compliance checks: SimpleSwap's AML and KYC policy says it can temporarily freeze any transaction for review and can ask for identity documents, source of funds, or a liveness check when risk triggers appear. Some users report swaps being held for long periods during reviews. Restricted countries: the terms of service exclude users in several jurisdictions, including the United States and its territories and the United Kingdom, among others. Check the current terms of service before you use it. Counterparty risk: while a swap is in progress, your funds are with SimpleSwap and its liquidity providers. Start with a small amount. Company details: the terms do not name a legal entity. App store listings show Simple Swap LTD. How to swap into Vaulta (A) Set up a Vaulta wallet, such as Anchor or Blocksfinity Authenticator, and note your account name. Open SimpleSwap and pick the coin you are sending and Vaulta (A) as the coin you want. Choose a fixed or floating rate and enter your Vaulta account name as the recipient, plus a memo if your destination needs one. Send the exact deposit shown, within the time window for fixed-rate swaps. Track the swap on the status page and confirm the A arrives in your account. Pros and cons Pros Fast, simple swaps without creating an account. Very wide coin coverage, including Vaulta (A). Fixed-rate option for predictable results. Card purchases available through Mercuryo. Cons Not available in the United States, the United Kingdom, and other restricted countries. Swaps can be frozen for compliance review, sometimes for a long time. Card purchases carry noticeably higher fees. Custodial during the swap, with limited public information about the operating company. FAQ Do I need an account? No. Standard swaps work without sign-up. An account is optional. Can I still swap EOS? The EOS listing is marked delisted. Use Vaulta (A), which replaced EOS at a 1:1 ratio in 2025. Is SimpleSwap anonymous? Not in every case. Any swap can be held for KYC review if it triggers risk checks. Disclosure: the SimpleSwap link on this page is a referral link, and BlockzHub may earn a commission when it is used.

Electrum
0.0Electrum: a lightweight Bitcoin wallet since 2011 Electrum is a free, open-source Bitcoin wallet for Windows, macOS, Linux, and Android. It has been developed since 2011, which makes it one of the oldest Bitcoin wallets still in active use. It is known for fast startup, strong hardware wallet support, multisig, and built-in Lightning. The latest stable release is Electrum 4.8.2, published on September 11, 2026 as a security update. What it is Electrum is a light client. Instead of downloading the whole Bitcoin blockchain, it connects to Electrum servers that index the chain and verifies your transactions using Simplified Payment Verification (SPV). Your private keys are generated and stored on your device, encrypted with your password. Electrum servers never see your keys. Electrum supports Bitcoin only. It does not hold Vaulta (A), Ethereum, or other assets. Key features Fast startup: no full blockchain download, so the wallet is usable within seconds. Seed phrase backup: restore your wallet on any device from your Electrum seed. Hardware wallets: plugins for Trezor, Ledger (including the Nano Gen5), BitBox02, Coldcard, Jade, KeepKey, and others. Some older devices, such as BitBox01 and Safe-T, now show deprecation warnings. Multisig: create wallets that need several keys to spend, for example 2 of 3. Watch-only and cold storage: keep keys on an offline machine and use a watch-only wallet to create unsigned transactions. Lightning Network: open channels, make fast low-fee payments, and use submarine swaps and watchtowers. Fee control: set custom fees and bump stuck transactions with Replace-By-Fee. Two-factor option: the TrustedCoin plugin offers a 2-of-3 wallet where a third-party service co-signs after a one-time code. It is optional. Plugins: add features such as Nostr Wallet Connect. Wallet types When you create a wallet, Electrum asks which kind you want: Standard wallet: a single seed phrase controls the wallet. This suits most users. Wallet with two-factor authentication: a 2-of-3 setup with the TrustedCoin co-signing service. It adds protection against a compromised computer, but the service charges a fee and you depend on it for routine spending. Multi-signature wallet: you choose how many cosigners exist and how many must approve each payment. Each cosigner can be a hardware wallet. Import addresses or keys: create a watch-only wallet from public addresses, or sweep existing private keys into a new wallet. Security Download only from electrum.org: fake Electrum builds have been used to steal coins. Verify the GPG signatures that come with each release. Keep it updated: every release since 4.6.2 is marked as a security update. Version 4.8.2 fixed Lightning channel backups for some channel types, and affected users should export new backups. Beware of fake server messages: attackers have run malicious servers that showed fake "update" pop-ups. Real updates come only from electrum.org. No private support: the Electrum developers do not offer private support. Anyone who contacts you offering help is an impostor. Back up your seed offline: anyone with the seed can spend your coins. How to get started Download Electrum from electrum.org, or install the Android app from Google Play or F-Droid. Android 8.0 or later is required. Verify the download signature, following the Electrum documentation. Create a new standard wallet, write down the seed phrase on paper, and set a strong password. Optionally connect a hardware wallet or set up multisig. Use the Receive tab to get a fresh address, and the Send tab to pay, adjusting the fee as needed. Running Electrum from source requires Python 3.10 or later. Most users should use the packaged releases. Pros and cons Pros Long track record and active development. Excellent hardware wallet and multisig support. Built-in Lightning. Free and open source. Cons Bitcoin only. The interface is technical for beginners. No iOS app. Relies on Electrum servers, which can learn which addresses you query unless you run your own. FAQ What is the latest version? Electrum 4.8.2, released September 11, 2026. Is Electrum custodial? No. Keys stay on your device. Does Electrum support Vaulta or Ethereum? No. It supports Bitcoin only. Can I use Electrum with a hardware wallet? Yes. Connect a supported device such as a Trezor, Ledger, BitBox02, Coldcard, or Jade when you create the wallet, and keys stay on the device. This listing is informational and is not financial advice.

Ledger: hardware wallets for self-custody Ledger is a French company, founded in 2014, that makes hardware wallets: small devices that keep your private keys offline and ask you to confirm each transaction on the device itself. Ledger now calls these devices "signers". They work with Ledger's companion app, Ledger Wallet (renamed from Ledger Live in October 2025), and with many third-party wallets, including Anchor for Vaulta (formerly EOS). What it is A hardware wallet separates your keys from the computer or phone you use online. Your device signs a transaction internally and sends only the signature back, so malware on your computer cannot copy the key. If the device is lost or broken, you restore your accounts on a new device with the recovery phrase you wrote down at setup. Ledger devices are non-custodial: Ledger does not hold your keys or your funds. Current device lineup Nano S Plus: entry-level, USB-C, small screen. Nano X: adds Bluetooth and a battery for use with phones. Nano Gen5: launched in October 2025 with a 2.8-inch E Ink touchscreen, Bluetooth, NFC, and USB-C. Flex: larger E Ink touchscreen, Bluetooth and NFC. Stax: the largest curved E Ink touchscreen in the range, Bluetooth, NFC, and wireless charging. The original Nano S is discontinued. Prices change often, so check the official Ledger shop. Key features Secure Element chip: keys live in a certified secure chip. Ledger lists CC EAL6+ for the Nano S Plus, Nano Gen5, Flex, and Stax, and CC EAL5+ for the Nano X. Wide asset support: Ledger says its devices support more than 15,000 assets across 100+ chains, through Ledger Wallet and third-party wallets combined. Ledger Wallet app: manage accounts, install device apps, update firmware, and buy, swap, or stake some assets through partners. Third-party wallets: connect your device to wallets such as MetaMask, Electrum, and Anchor so the keys stay on the Ledger. Ledger Recover (optional): a paid subscription, run with Coincover, that backs up encrypted fragments of your recovery phrase with identity verification. It is opt-in and not required. Security history Ledger's devices have a strong security record, but the company has had incidents worth knowing about: July 2020 data breach: customer contact and shipping details from Ledger's e-commerce and marketing database were leaked. No funds or keys were exposed, but customers were targeted by phishing emails and letters afterward. December 2023 Connect Kit exploit: a malicious version of Ledger's Connect Kit library briefly affected some dApps that used it, draining funds from users who signed malicious transactions. Ledger published an incident report. Ledger Recover debate: the 2023 announcement raised concerns about whether firmware could extract a phrase. Ledger maintains that the feature is opt-in and requires user consent on the device. Using Ledger with Vaulta Install the EOS app on your Ledger through Ledger Wallet. Vaulta uses the same chain and signing format as EOS. Close Ledger Wallet, then open Anchor in a supported browser (Chrome, Edge, or Brave) or the Anchor desktop app. Enable contract data in the EOS app settings so the device can sign A token transfers and other contract actions. Import or create a Vaulta account that uses your Ledger key, then use it with Vaulta dApps such as Unicove. Ledger's own EOS page still uses EOS naming and does not mention Vaulta or A. Ledger Wallet itself does not manage Vaulta accounts, so you need a third-party wallet such as Anchor. Setup and best practices Buy only from the official Ledger shop or authorized resellers, and check the packaging. Download Ledger Wallet only from ledger.com. Write your 24-word recovery phrase on paper or metal. Never type it into a computer, phone, or website, and never share it. Set a PIN and keep firmware up to date. Read every transaction on the device screen before approving, especially contract approvals. Pros and cons Pros Keys stay offline in a certified secure chip. Very broad asset support and many compatible wallets. A range of devices from budget to touchscreen. Works with Vaulta through Anchor. Cons Firmware is closed source, so users must trust Ledger's security reviews. Past data leak and supply-chain incident. Vaulta needs a third-party wallet and extra setup steps. Costs money, unlike software wallets. FAQ Is Ledger Live gone? It was renamed Ledger Wallet in October 2025. It is the same companion app. Can I store A on a Ledger? Yes, by using the EOS app on the device with a Vaulta wallet such as Anchor. Do I need Ledger Recover? No. It is optional. Your recovery phrase alone is enough to restore your wallet.
