Dai is a stablecoin. It is an Ethereum ERC20 token that is pegged to $1 USD — every Dai is worth $1, and will always be worth $1, regardless of how much Dai is in existence. There is no centralized authority like Tether that backs its value, and no traditional bank that backs each Dai with a real US dollar. There is nothing that can be shut down, and no centralized authority that needs to be trusted. Dai lives entirely within the Ethereum blockchain using smart contracts. *Features of Dai: 1. Dai is always worth $1 USD each 2. It can be freely traded like any other ERC20 token 3. Anyone with an Ethereum wallet can own, accept, and transfer it 4. It can be exchanged without any middleman 5. No individual person or company has control over it 6. No government or authority can shut it down *How Dai Works? Dai is a masterpiece of game theory that carefully balances economic incentives in the pursuit of one goal — a token that is continuously approaching the value of $1 USD. When Dai is worth above $1, mechanisms work to decrease the price. When Dai is worth below $1, mechanisms work to increase the price. The rational actors that take part in these mechanisms do so because they earn money anytime Dai is not perfectly worth $1. This is why Dai is always floating slightly above or below $1 — it is an endless wave function bouncing infinitely close to $1, but never quite achieving it. The farther Dai goes from $1, the more incentive there is to fix it. This is the magic of Dai. *How is Dai Created? Dai is simply a loan against Ethereum. By using the MakerDAO dApp, advanced users can take loans out in Dai against their ETH holdings. First, ETH is turned into “wrapped ETH” (WETH), which is simply an ERC20 wrapping around ETH. This “tokenizes” ETH so it can be used like any other ERC20 token. Next, WETH is turned into “pooled ETH” (PETH), which means it joins a large pool of Ethereum that is the collateral for all Dai created. Once you have PETH, you can create a “collateralized debt position” (CDP), which locks up your PETH and allows you to draw Dai against your collateral, which is PETH. As you draw out Dai, the ratio of debt in the CDP increases. There is a debt limit that sets a maximum amount of Dai you can draw against your CDP. Once you have Dai, you can spend or trade it freely like any other ERC20 token. *There are several important reasons why you would create Dai, despite the hassle: 1. You need a loan, and have an asset (ETH) to use as collateral for your loan 2. You believe ETH is going up in value. You can use your CDP to buy ETH on margin — you lock up your ETH in a CDP, draw Dai against it, use the Dai to buy more ETH on an exchange, and then use that ETH to further increase the size of your CDP. This can be accomplished without any third-party or centralized authority allowing you to do so — margin trading can be accomplished entirely on the blockchain. 3. The demand for Dai has driven the price above $1 USD. When this occurs, you can create Dai then immediately sell it on an exchange for greater than $1 USD. This is essentially free money, and is one of the mechanisms the Maker system uses to keep Dai pegged to $1 USD. Dai being worth over $1 USD encourages more Dai to be created. These three reasons are enough to ensure that Dai is continually created.

A Sai wallet is a digital or physical tool that stores your public and private keys. These keys are needed to access and control your crypto assets. The wallet doesn't store the actual coins but lets you interact with the blockchain. It’s the gateway to sending, receiving, and safeguarding your Sai.

Open your Sai wallet and select “Send.” Paste or scan the recipient’s wallet address, enter the amount of SAI, and confirm the transaction. Once confirmed, the recipient sees the funds in their wallet.

Go to the “Receive” section in your Sai wallet. Copy your wallet address or use the QR code. Share it with the sender. After the transaction is broadcast and confirmed on the blockchain, your wallet shows the updated balance of SAI.

It’s a unique string of letters and numbers linked to your wallet’s public key. Others use this address to send you SAI. Think of it like your crypto account number; it tells the network where to send the funds, but it doesn’t give access to your private key.

To securely store your Sai, consider using a hardware wallet like Cypherock X1. It splits your private key into five cryptographic parts across secure components, ensuring your funds stay safe even if you lose one, two, or even three parts.

Yes, modern hardware wallets like Cypherock X1 support thousands of coins and tokens, including Sai. You can manage your entire crypto portfolio across multiple wallets and blockchains seamlessly.

With Cypherock X1, your private key is split into five secure parts. As long as you have two parts of the hardware components (an X1 Card or the X1 Vault), you can recover your Sai even if the other three parts are lost.

Look for tamper-proof smartcards, EAL6+ certification, offline verification, and decentralized key storage. Cypherock X1 offers all of these, ensuring bank-grade security for your Sai.
