Vault ethereum agree with you that providing only a vault ethereum to withdraw a fixed amount of underlying is not a good idea because it leaves dust, which is why we provide a redeem method! Let us know. January 13,am 16 Approving the vault to pull underlying from users, with permit or any other method, would open the door for griefing attacks. One of the benefits of Vault is that it provides many forms of authentication which means that you can avoid the awkwardness of handling certain kinds of passphrases.

Schnorr signatures, which are slightly smaller and more flexible for use in complex smart contracts, have been proposed as a replacement for ECDSA signatures. Encryption Encryption is a collection of information-hiding methods that make information unreadable to all but the intended recipient. Encryption locks information with a secret key that only the information creator and sometimes the recipient controls. Cryptocurrency and digital assets are protected by a type of encryption known as "asymmetric.

Asymmetric encryption is widely used because it does not require a private way to send someone a decryption key. Before asymmetric encryption was invented, it was risky to find a safe, secret way to deliver a symmetric decryption key. As computer processors become more powerful, encryption standards that are considered very strong today eventually will become crackable in relatively short periods of time, and thus ineffective.

Encryption is different from hashing. Encryption Keys Encryption keys are long, mathematically-derived alphanumeric strings used to lock and unlock encrypted data. Cryptocurrency uses a type of encryption called asymmetric encryption, which requires the use of both a private key and a public key. Public keys are used to derive payment addresses, and to verify that a private key signature is valid.

Your public key can be shared. Private keys are used to sign transactions. Private keys should never be shared! Cryptocurrency wallets keep private encryption keys secret. If the device on which you keep your crypto wallet is not highly secure say, a "hot wallet" on a high-usage laptop that is connected to the Internet , a hacker might be able to steal your private keys, and then steal your cryptocurrency. If you keep your encryption keys secret in your crypto wallet, but you somehow lose access to your wallet and to your backup seed phrase, there is no way to restore your private encryption keys, and therefore no ability to recover your cryptocurrency.

It is a great responsibility to keep your private encryption keys accessible but secret. This is why it is so important to back up your seed phrase - it allows you to rebuild a new wallet with your original encryption keys, and to regain access to your wallet funds. Ethereum Ethereum is a wildly-popular blockchain that has somewhat different characteristics than Bitcoin. While Ethereum has a digital currency called "ETH," Ethereum is even more well-known for its support for highly-customizable Smart Contracts.

Smart contracts have made Ethereum a digital marketplace with nearly unlimited ability to leverage and integrate financial transactions, games, and a plethora of other digital services. These applications are known as Ethereum dApps. ERCs are a subtype of Ethereum Improvement Protocols EIPs , which are used by Ethereum contributors to collaboratively evaluate proposals to improve or add feature functionality to Ethereum.

Each ERC describes the mechanics for new application-related functionality on the Ethereum network, such as contract standards, new token types, and wallet formats. The most well-known characteristic of the ERC token is that all ERC tokens associated with a Smart Contract are interchangeable fungible , similar to the way that all money of a given denomination is interchangeable.

However, even though ERC tokens are interchangeable within their defined type, the value of different ERC token types will vary: not all ERC token types even have value. It is largely due to the fungibility of ERC tokens that they are the most common type of token used in Smart Contracts related to cryptocurrencies. ERC tokens have a small set of standard functions that indicate who owns them by Blockchain address , the total count of tokens, and methods by which tokens may be transferred between parties.

Developers may optionally add custom functions to the standard ones. The most well-known characteristic of the ERC token is that it represents a non-fungible token NFT - in other words, it is a unique and non-interchangeable good for example, digital art, an insurance policy, or a lottery ticket. Hardware Wallet A hardware wallet is a digital asset management hardware device that specializes in acting as a host to your cryptocurrency wallet, including your private encryption keys.

Hardware wallets store encryption keys in a highly-secure way, and usually offer additional wallet functionality such as the ability to generate seed phrases, and perform crypto spend transactions. Trezor and Ledger are two well-known brands of hardware wallet.

Hash functions are deterministic, meaning that a given input always generates the same hash value. Because of these characteristics, hashes offer a secure way to validate the authenticity of information by comparing the hash outputs of two inputs, without having to compare the actual inputs. Since hashing is a one-way function, the hash value can not be used to learn what the original string value was.

A good hash algorithm also will be "collision-resistent," meaning that no two different inputs should produce the same hash. The only way to figure out what original value might have been used to produce a given hash value would be to perform an enormous number of guesses with different inputs until one of the output values matches the expected hash string.

This kind of "brute-force" guessing is statistically impractical. Hash functions are used for data transformations in a wide variety of contexts, including in many standards-based cryptocurrency-related operations. For example, the BIP39 standard that is fundamental to many cryptocurrency wallets relies on the SHA hash algorithm as part of the calculations to generate keys from a seed phrase, as does BIP Hierarchical Deterministic Wallet A Hierarchical Deterministic Wallet is a type of hot or cold wallet that follows the BIP32 standard to organize and manage your seed phrase, encryption keys, and wallet addresses in a predictable and convenient way that allows you to rely on one master seed phrase that can be used to reconstruct your wallet if and when needed.

Hot and Cold Wallets A cryptocurrency wallet can be used to buy and sell cryptocurrency, and it holds digital assets in sort of the same way as a physical wallet holds traditional printed cash. Crypto wallet users may choose to rely on a custodial crypto wallet, where a third party retains control of the cryptocurrency, or a non-custodial wallet, where users own and control their own cryptocurrency. There are significant risks in trusting a third party to hold your cryptocurrency for you in a custodial wallet - in fact, trusting a custodian to control your cryptocurrency wallet keys for you negates a significant element of the fiat currency risk-mitigation value that cryptocurrency offers.

The term hot wallet refers to a cryptocurrency wallet that is stored online, connected to the Internet, whether that wallet is stored on an exchange or on your own device. A cold wallet stores cryptocurrency keys offline. There are advantages and disadvantages to both types. Cold storage is generally more secure, but factors like the possibility of hardware vulnerabilities and user error lead to potential security issues even for cold wallets.

It is important to follow security best practices when configuring and using all wallet types, and to choose products and services that offer secure encryption and limited surface area for attack. Examples of hot wallets are downloadable applications, exchanges, and any software service that is connected to the internet. Cold wallets are exclusively stored offline, and can be in the form of USB drives e.

Effectively it is a peerpeer payment protocol designed to be layered on top of a Bitcoin blockchain and work securely "off-chain," without delegating custody of funds. While Bitcoin is focused on extreme security and finality of transactions, which limits its speed and imposes significant transaction costs, Lightning network improves the scalability challenges of blockchains, allowing transactions to be completed instantaneously, and lowering transaction costs to sometimes just a fraction of penny.

Merkel Tree aka Hash Tree A Merkel tree allows efficient validation of large, related data sets by associating each tree node with hash values calculated from its children nodes. Merkel trees were patented in by Ralph Merkel, and later, Satoshi Nakamoto incorporated Merkel trees into the initial Bitcoin design. Miniscript Miniscript is a compiled, structured language used for writing a streamlined subset of Bitcoin Script.

It supports efficient analysis, spending policy composition, generic signing, and more. MPC Multi Party Computation Multi-Party Computation MPC technology is a category of cryptography technologies used to produce and store distributed key shares, which are then used by multiple parties to jointly generate partial signatures.

Multi-Party Computation uses Distributed Key Generation and other mechanisms to avoid the need to assemble an entire secret in one place. When a sufficient number of partial signatures have been collected, a single signature is generated from them, and the transaction can be validated and approved.

Although the entire private key is not stored in any one place, the distributed spending approvals can be recorded off-chain and made auditable. MPC has been under development in various forms since the s. Multi-Signature aka Multisig "MultiSig" is a type of crypto transaction that requires multiple signatures to approve spending.

Imagine a safe deposit box where multiple keys are required for entry. Wallets that support multisig transactions include Electrum and Armory. The term multisig can be used broadly to refer to an array of current and future implementations that allow cryptocurrency to be spent only when multiple participants have indicated their approval of the transaction.

Multi-sig decentralizes the private key signing architecture by requiring a certain number of keyholders to authorize a transaction by signing it, thereby making the signing process less vulnerable to attack compared to a case where there is just one key and one signer. In computer software generally, and for cryptocurrency specifically, NIST is relevant as a source of guidance on encryption standards. NIST updates their guidance on encryption over time to reflect changes in computer capabilities.

There is no single global standard or law regulating encryption technologies, although the International Organization for Standardization ISO also sets standards for many technologies including encryption. Non-Fungible Token NFT A Non-Fungible token is a digital asset that is associated with a unique and non-interchangeable good for example, digital art, an insurance policy, or a lottery ticket.

For more information, see Vault12's article about NFTs. Output Descriptors Output descriptors are strings that contain all the information necessary to allow a wallet or other program to track payments made to or spent from a particular script or set of related scripts i. Output descriptors combine well with miniscript in allowing a wallet to handle tracking and signing for a large variety of scripts.

They also combine well with Partially Signed Bitcoin Transactions PSBTs in allowing the wallet to determine which keys it controls in a multisig script. Among other advantages, this allows clients to sign transactions while offline if desired. It is mostly popular for Bitcoin Multisignature solutions. Passphrase for Seed The BIP39 passphrase, sometimes referred to as an "extra word" although it does not need to take the form of a single word can be used as an additive authentication feature beyond the standard word seed phrase.

If used, the passphrase should be securely backed up and stored, because like your seed phrase, if you forget or lose it, you will lose access to your cryptocurrency. Many crypto wallets offer this as an advanced feature, since it does make your backup task a little more complicated. In order to provide an additive security layer, the passphrase would need to be stored separately from the seed phrase itself.

Like any password, if it is set, the seed extension passphrase should be complex in order to provide significant additive security. Private Key Cryptocurrencies are built on a public-key cryptographic system that uses pairs of keys. Public and private keys are derived from the master seed phrase.

Creating a crypto wallet begins with the generation of a random seed that is used to calculate your private key. Once generated and backed up, the private key is used by your crypto wallet to digitally sign crypto spending transactions that you authorize. Using crypto wallets to keep your private encryption keys secure is important because wallets avoid the need for a 3rd party like an exchange to have access to your private keys.

Cryptocurrency wallets not only keep private encryption keys secret, but can also tell you what your publicly-shareable public key is. However, if the device on which you keep your crypto wallet is not secure say, a "hot wallet" on a laptop that is connected to the Internet , a hacker might be able to steal your private keys, and then steal your cryptocurrency. The private key must also be backed up and protected from accidental loss, because if it's lost it cannot be recovered and the funds secured by it are forever lost, too.

Now imagine if each dice was number 1 through a billion. The chances of rolling the same becomes extremely small. This concept represents collision resistance. Toka app work while you just live.
