Thanks man! Swapping abUSDC to USDC didn't work on saber, did it on Jupiter!
Glad I could help!
Can you explain why you say to stop using DeFi bridges when you are using DeFi bridges? I'm a bit confused.
Use bridge aggregators instead 💪🏻

How to withdraw tokens from smart contract address to wallet
It depends
Johnny, I need a one on one with you. I hope I can get the opportunity.
I do offer 1-1 consultation paid sessions, feel free to reach out at Johnny@johnnytime.xyz
Ingot scammed other dya in honey pot..the guy had 3 wallets. One had 8.7 million other one had 687k then other one had 200+k so my question is...why hasnt he cashed that out?? Why has it been sitting in these wallets if hes running honeypots? How do they cash those funds out without getting caught? Somehow someway it has to be put i to money or on a card that he can use for funds right? So how? Thats what i wanna know.
Good question 👀
Jasmy token, should I have bought this a month ago when I saw people pump this.. instead bought a little up a few percentages.. missed the boat instead holding $Gala $ADA $STORJ $LTC they aint moving like that 😮
Better luck next time 😅
Thx for your video, help many people from scammer
❤️🙏🏻
Maybe someone here can tell me how I can withdraw dollars to a card from an OKX wallet, if I only have the phrase: head isolate sound end kit industry choice festival limit stable dolphin derive
And how to calculate my impermanent loss when im out of range? because as i can understand you dont just get 2 assets converted into 1 underperforming but you lose some % of your total value.
Si the thing is that the more you get close to the edge, more is converted to the other asset, through the range.
Hi, how do you get the syntax highlighting when marking audit issues and audit info?

Hi Johnny - is it good to look at DexScreener's contract info in Go+ Security? I saw three issues with DOLA almost immediately.

Hello Johnny.. How can I transfer or withdraw to my wallet? How do I know my wallet when transferring or withdrawing?
You need to check your wallet address
love it, known caddi for a while, thx for the in depth video
Glad you enjoyed!
Never seen such morons. The universe is doomed.
I like the fact you are actually showing this on a portfolio with some money attached to it. Many would probably just use 10$ to 100$. I would love to see a video in this series about diversification in the different DeFi protocols, take beefy finance etc even though they seem to take security very seriously with audits pretty often how would you go to choose your protocols? Would you have it all in one protocol like Beefy or do you diversify in different defi with the stablecoin yield strategy to minimize risks?
This is exactly what I explained here :) ruclips.net/video/1EIGRE040jc/видео.htmlsi=siFJ2U-dRsCkocs4
Could you explain more about how Caddy ensures the security of bridge transactions and why it's safer than using individual bridge contracts? It'd be awesome to see a video diving into this topic! Hoping to see more of your great content on RWA altcoins.
It’s essentially preparing the same metamask transaction that the bridge makes, it has no intermediary smart contracts in the middle but you interact directly with the bridge smart contract, it just aggregates all of them for you In one price and shows you the best options :)
Great content 🏆🏆🏆 Does this apply to NFTs also on Eth chain? How about Solana coins if have trezor model 1?! thank u 🙏
Thanks 😊 Not sure about NFTs since I didn’t hold any nfts on my trezor
Bro , is it really worth it to learn about smart contract audit, I am bit confused about the ai stuffs , i really like your advice.
Yes 100%

Security?

How exactly does Symbiosis Finance work for cross-chain transactions, and could you make a video diving deeper into its features and usability? I'd appreciate more insights on RWA altcoins in your videos.

How can I use symbiosis to access funds stuck in one blockchain when I don't have the native currency for transaction fees in another? Would you be open to producing a video guiding us on managing our Crypto profits within the blockchain? Would you put them in Bitcoin? Or maybe in some RWA projects?
Great video

How can I transfer to Metamask via Ens Dao with etherscan?
What do you mean?
Thanks,i already done that. please how do i fund the heco wallet using meta mask?
Not sure tbh
good
Thanks
The naming for the contracts and variables are so damn confusing. The interfaces are Lender and Borrower, the contracts are Receiver and ReceiverLenderPool, and in the receiver contract the lender is the pool address. That was probably the only difficult part of the challenge. Anyways I came here just to vent :p

this is also very very dangerous, not only it allows white hackers to find bugs, but this way black hackers could easily search for exploits
Indeed, that's why the team is not granting Mainnet access to everyone and controlling it.
