I have never got work before, I hope it works! xDAI is a POSDAO consensus sidechain of Ethereum with native currency of xDAI instead of GAS (ETH) to use for onchain transaction. Website: https://www.xdaichain.com/ Blockexplore: https://blockscout.com/poa/xdai/ TokenBridge (DAI to xDAI): https://docs.tokenbridge.net/xdai-bridge/about How to use: 1: Setup wallet Here are screenshots and links of wallets. Metamask setup with RPC Please follow the instruction below https://www.xdaichain.com/for-users/wallets/metamask/metamask-setup or Use Nifty wallet which is native xDAI wallet. https://chrome.google.com/webstore/detail/nifty-wallet/jbdaocneiiinmjbjlgalhcelgbejmnid/related?hl=en   2: Get xDAI Use xDAI xbridge to convert DAI to xDAI. https://bridge.xdaichain.com/ I connected both metamask and Nifty wallet and the website automatically chose Nifty wallet to connect as of 31/Oct/2020.  3: Stake "Stake" It is recommenced too use easy-staking by xDAI website. https://easy-staking.xdaichain.com/ Scheduled withdrawal take 12 hours to withdraw with 0% fee.   There is also stake Beta version function on Blockscout which needs "STAKE" token on xDAI chain. Easy-staking is using "STAKE" on mainnet.  Walkthrough of Uniswap liquidity mining, how to earn UNI token. 1: Go to https://app.uniswap.org/ (Free 400 UNI is already claimed at the screenshot below) More details at: https://uniswap.org/blog/uni/  2: Provide liquidity Go to "Pool" tab https://app.uniswap.org/#/pool Same function as before, but if you are doing this for the first time: 1: Provide 50/50 liquidity e.g. ETH/DAI 50/50 ratio with USD price Not like Balancer pool with AMM (Automated market making) There was no indication during this step but you will get UNI-V2 XXX-XXX (pair) token   3: Go to "UNI" tab Deposit liquidity pool token which is given with providing the liquidity into the pool above. "UNI-V2 ETH-DAI token" in this case This is similar to Curve LP token. https://app.uniswap.org/#/uni There are currently 4 pools as of Sep 18 2020. ETH-DAI liquidity was provided above.  4: Claim, Deposit, Withdraw Claim to take the UNI rewarded token Deposit to earn more UNI Withdraw to unstake the UNI-V2 staked token and also claim UNI token  5: Remove liquidity Go to the pool you provided and remove liquidity to put the cryptos back into your wallet. Thanks! Additional You will earn more fee with UNI and ETH by providing UNI/ETH pair than above the instruction as of Sep 19. https://uniswap.info/pairs   Links to check APY for Defi projects.
Please note that high reward has high risk, be aware of loss of your funds by such as smart contract bug and impermanent loss. Yield farming https://yieldfarming.info/ https://yieldfarmingtools.com/ http://pools.vision http://www.predictions.exchange Staking https://www.stakingrewards.com/ Interest rates https://defirate.com/lend/ https://defiprime.com/defi-rates http://www.predictions.exchange/compound/None https://compound.finance/markets How to add liquidity in balancer pool Balancer: https://pools.balancer.exchange/ Predictions.Exchange http://www.predictions.exchange/ Predictions.Exchange (Balancer) http://www.predictions.exchange/balancer/None 1: Go to https://pools.balancer.exchange/ and connect to Wallet, I am using Metamask here.  (1): Go to http://www.predictions.exchange/ to check the rates  2: Wrap ETH or prepare liquidity that you want to add I wrapped eth on balancer below the left box.  3: Pick a pool You can click the pool contact address below. 4: Add liquidity Each pool has rates of liquidity to provide, you can provide single asset bby clicking "single asset" tab and choose the liquidity you have. I chose WETH in this case. 5: Click "Unlock WETH" and confirm with Metamask. Cheap GAS day today! yay   Finally to click "Add liquidity"  You will get BPT (Balancer Pool Token), and click "Remove liquidity" to take your reward and unwrap WETH to ETH whenever you want. Please note that DeFi is a testing phase. You may lose your fund.
This pool work as: - Automatically keep the ratio of 34% WBTC, 50% BAL and 16% WETH - 105.69% RoL (What is RoL, Return of Liquidity?) according to http://www.predictions.exchange/balancer/None as of August 10 2020 So that is BAL price goes up and amount of BAL goes down and amount of WBTC and WETH go up and vice versa. You may not be able to connect Metamask closing the browser or log off computer at https://pools.balancer.exchange It happened to me, I use Mac and Brave browser. I first logged in at https://balancer.exchange/ and go to https://pools.balancer.exchange I manage to log in Balancer Pool. It worked. This is a brief walkthrough of Uniswap V2. 1: Go to: https://app.uniswap.org/#/swap A orange Popup window may show to allow Uniswap to connect to Metamask.  2: Click "Connect to Metamask"  3: SWAP This is like "Shapeshift". Example of Swap function below. The swap will be failed if the conversion of swap goes lower than the minimum received during the transaction time. You can pay  You see the transaction detail below. You will go to metamask popup window after clicking the "Confirm swap"  Yes GAS fee is $2.23 USD. I supposed to have GAS configuration boxes here with advanced GAS setting on Metamask but it does not show. Well DeFi is still a testing phase. You can see effective GAS price here. https://www.ethgasstation.info/  You can change the slippage on the setting on Uniswap.  4: POOL This is to provide liquidity into Uniswap pool to get rewarded "liquidity provider fee". You have to provide same USD amount of 2 coins. Example of ETH and DAI below.  5: Connect to Mobile Metamask Click WalletConnect and a QR code will appear on the screen.  Scan the QR code on your mobile by clicking the Square mark on the top right on the screen below. You need Metamask on your Mobile phone. I also tried on JAXX but there is no way to connect at the moment.  Click connect.  Done!  Please check previous post if you don't know anything about Synthetix. You should have sUSD if you have been staking Synthetix and sitting in your wallet doing nothing aside from Mint and Burn to adjust the collateralization ratio unless you are a trade on their platform. This is to stake sUSD via Curve 1: Go to https://beta.curve.fi/susdv2/deposit  2: Click "Deposit and stake" and accept few to several transaction on your wallet . . . Done! You can check your staking at https://mintr.synthetix.io/ And click LP REWARDS   After a week of staking sUSD via Curve LP. 1105.96 USD staking 1.88 SNX reward 1.88 SNX x 2.84 (Current SNX USD price) = 5.34 USD 5.34 / 1105.96 USD staking USD x 100 = 0.48% per week as of July 2020  Finally to exit and withdraw the staking. 3: Click EXIT: CLAIM & UNSTAKE It will return your staking with "Curve LP" Therefore you will need to switch back to sUSD  In order to do that:
4: Go to https://beta.curve.fi/susdv2/withdraw You can see the screenshot above and click "withdraw". Popup window or your hardware wallet will as you to confirm the transaction few times same as when you staked. The top box "Share of the liquidity (%)" should be 100 if you want to withdraw all. Done! Synthetix staking and basic functions (There are "Exchange", "Mintr" and "Dashboard".) https://www.synthetix.io/ It is high staking reward, one of the highest as you can see from the link below. https://www.stakingrewards.com/asset/synthetix-network-token I am going to talk about Mintr to focus on staking for what it looks like, how it works and risk. I spent some time on this staking rewards and this is the result. 1: Go to https://mintr.synthetix.io/ And connect to your wallet with ETH and SNX.  It looks like this below after connecting to your wallet.  2: Go to "MINT" And stake SNX by minting sUSD. It will be locked for 24 hours in the current rule. This adds liquidity pool of their "Synthetix" exchange and you can check at "Dashboard". Current minimum collateralization ratio is 800% (792% to be exact to claim reward) which means you mint sUSD 1/8 of staking SNX USD value. Your minted sUSD also goes to debt in other words you need to pay back the debt to unlock the staked SNX. I will explain these more later.  3: Go to "CLAIM" This is to get paid with your staking. The payout is on every Wednesday 10:00 UTC and 1 week to claim the reward. You will lose the reward if you didn't claim. ***Note that the claimed SNX is locked for a year. *** It would be necessary to forecast the market in a year. If you think it will be gone in a year and you should not be staking. Collateralization ratio needs to be higher than 800% to be able to claim. The ratio can be changed by the price of SNX as liquidity pool increase/decrease. You will need to burn sUSD to add Collateralization ratio if it is lower than 800%.  This is how it works below. https://www.synthetix.io/uploads/synthetix_litepaper.pdf Liquidity pool increase = SNX and sETH price increase Liquidity pool decrease = SNX and sETH price decrease sUSD price is stable = Ratio of debt goes high/low of total liquidity. In general, it is good to have SNX or sETH when the market is going up, and hold more sUSD when the market is going down.  4: "BURN" Click "Fix your Collateralization Ratio" to be able to claim if your ratio is not enough. And also pay off all the debt by burning sUSD to unlock the staked SNX.  5: Other functions "TRADE" Not available as of June 6 2020. Go to "Exchange" instead. "TRANSFER" As it says, transfer SNX. Nothing much.  "TRACK" To track your debt, minted sUSD by staking SNX  Finally to talk about these tabs.  "DEPOT" stands for deposit to sell your sUSD for ETH. You can do it as their exchange and also Uniswap and other DEX. "TRANSACTIONS" shows your previous related transaction such as mint, burn, claim, depotsit and sell sUSD etc. "ESCROW" is to escrow rewards SNX therefore nothing you can do for a year. "LP REWARDS" is an interesting part that you can add liquidity to Synthetix exchange by Uniswap and other things which are more complex. The options are below.  Multi signature wallet with Electrum https://electrum.org/ Download wallet from https://electrum.org/#download There is a single point of failure of using HW wallet. This tutorial is for 3 cosigner with 2 signature 3 Cosigner = Electrum wallet/ LedgerNano/ Keepkey Therefore one HW can be backup of the other. Start the app and you will see the screen below   You can choose the degree of security here.   Create a new seed (1: Electrum wallet co-signer)     Cosigner with hardware device (2:LedgerNano 3: KeepKey)    You will be asked for a password (If you set) for the Cosigner 1: Electrum wallet  Below is if you chose Ledger to cosign   This is for Keepkey to Cosign. You should be familiar if you have used KeepKey before otherwise it looks like this below.      Done!
I found multisig with 2 hot wallets here. https://www.youtube.com/watch?v=QMl522DA-oo Thank you to the Youtube channel "Hodl Hodl". |
