93/100 security score out of the box — built in 4 days during @FrontierHackathon by a self-taught developer from Brazil 🇧🇷. Proof that quality and speed can coexist.

Finding #3: Arithmetic Overflow/Underflow. SOL transfer amounts could overflow. Fix: Using checked_add() and checked_sub() for all arithmetic operations on token amounts.

Finding #2: Missing Owner Check. Account ownership isn’t always validated. Fix: Using Anchor’s Account<’info, T> type which automatically validates account ownership on-chain.

Finding #1: Missing Signer Check. Some instructions don’t verify the transaction signer. Fix: Adding #[account(signer)] constraints to ensure only authorized wallets can execute sensitive operations.

“SendSol is a Pix-like payment layer on @Solana. Instead of copying long wallet addresses, users send SOL using simple @usernames. Built with Anchor during @FrontierHackathon 🚀”

We ran @VaultMindHQ security audit on SendSol’s Solana smart contract. Here’s what we found 🔍 Score: 93/100 🧵

That’s how crypto works today.
No undo.
No support.
No second chance.
So why are we still using addresses like this?
7xK3...9LpQ
SendSol replaces that with usernames.
Because sending money shouldn’t feel like defusing a bomb.
Would you trust this? 👇

Do you know your wallet address by heart? 🤔
Something like:
7xK9...aP93...QzT1
Probably not.
What if, instead, you could use a simple @name linked to your wallet — so you can be sure you're sending to the right person?
Like a Pix for Web3.
Would you use it? 👇

Sending crypto is still broken.
You copy.
You paste.
You pray it’s the right address.
One mistake = money gone forever.
Pix solved this in Brazil.
Why can’t crypto do the same?
That’s why we built SendSol.
Send SOL using a simple @username.
No long addresses. No stress. 😁

Sending crypto still feels harder than it should.
Long addresses, copy/paste… always that small fear of getting it wrong.
With SendSol, you can just use a username — like Pix.
Simple, and a lot less stressful. 🚀

Sending crypto shouldn’t be this hard.
With SendSol, you just use a username.
No long addresses. No mistakes.
Inspired by Pix. Built on Solana.

Introducing Sendsol ⚡
Sending crypto is still too complicated
Long wallet addresses.
Easy to make mistakes.
Pix solved this in Brazil.
Now we’re bringing that simplicity to Solana.
→ No wallet addresses
→ Just a key
→ Instant transfers
Crypto should be simple.
