TL;DR

Keys > coins.
Hot for pocket money, cold for life savings.

Verify, don’t trust, and never type your seed anywhere a browser can see it.

That and more are what I have learned so far about crypto wallet.

A WALLET is NOT a purse.
A crypto wallet is just a key chain, not a purse.
It holds two strings:
Public key = your email address on the blockchain
Private key = the password to move anything.
Lose the second one = lose the coins.

Next-Gen Stuff Coming

MPC wallets (no seed, no single point)

Account Abstraction (pay gas in any token)

Passkeys (Face-ID to sign)

Early, but keep an eye on ERC-4337 and WebAuthn.

Backup Levels (good → paranoid)

1. Paper in home safe

2. Fireproof bag + safe

3. Steel stamp (Billfodl, Cryptosteel)

4. Shamir shards split between cities

5. Bank vault box (seed + passphrase)

Common Scams Bingo

❌ “Validate your wallet” DM

❌ Google Ads that look like OpenSea

❌ Airdrop links in Elon replies

❌ Discord bot telling you to “sync”

Rule: If it rushes you, it’s robbing you.

WalletConnect Magic

Scan QR → phone signs → dApp receives proof.

Private key never leaves your device.

Always check the domain on the phone screen before you approve.

Social Recovery

Lose your seed?

3 of 5 guardians can rebuild your wallet.

Guardians should be people you trust but don’t live with.

Argent and Loopring offer this today.

[Real Samuel @Realsamuel114s]

Smart-Contract Wallets

No single key—rules live on-chain.

Examples:
3-of-5 friends must sign

Spending limit/day

Recover via email + guardian
Trade-off: higher gas, cooler super-powers.

Hardware Wallet Ritual

a) Buy from the maker, not Amazon.

b) Update firmware before first use.

c) Write seed offline, never photograph.

d) Pin + passphrase = duress wallet (plausible deniability).

Token Approval Hell

DeFi apps ask “Can I spend ∞ tokens for you?”

One click later a hacker can drain you.

Rabby & https://t.co/b7raXRIj5T show human-readable allowances—use them.

Gas = Postage Stamp

You pay miners/validators in native tokens (ETH, MATIC, SOL) to include your tx.

Wallets let you choose slow/cheap or fast/expensive.

Use https://t.co/dZaYbE1KPK before you send.

[Real Samuel @Realsamuel114s]

Signing = Proof of You

When you “sign” a tx you’re mathematically stamping it with your private key.

The network checks the stamp without ever seeing the key.

Neat trick called ECDSA.

Derivation Paths (boring but expensive)

m/44'/60'/0'/0/0 tells the wallet which highway to drive on.

Wrong path = right seed, zero balance panic.

Most wallets auto-pick; power users check.

Address Formats Cheat-Sheet
Bitcoin:
1… Legacy
3… SegWit
bc1… Native SegWit (cheapest fees)

Ethereum:
0x… (all the same, checksum caps = typo protection)

Wallet Types (quick menu)
1. Mobile (Trust, MetaMask)
2. Browser (Rabby, Phantom)
3. Desktop (Electrum, Sparrow)
4. Hardware (Ledger, Trezor)
5. Smart-contract (Argent, Safe)
6. Paper (literally QR codes)

TYPES OF WALLET
Hot vs Cold
🔥 Hot wallet = lives online (phone, browser).
🧊 Cold wallet = lives offline (USB stick, steel plate).
Hot is convenient, cold is cremation proof.

[Real Samuel @Realsamuel114s]

Math > Metal
Keys are simply giant numbers (256-bit).
Your 12/24-word seed phrase is a human readable translation of that number.

Write it on paper and keep it safe, not iCloud.

I am so happy to attend my first virtual class in the @PercorsoTech Web3 and blockchain technology cohort 1 that kick started on Monday 8th September 2025, where I was given an assignment to write a thread about what I learnt. #PercorsoTech #Web3 #Blockchain

A Thread 1/8

[Real Samuel @Realsamuel114s]

ORACLES: Think of them as bilingual translators that feed real-world facts (scores, weather, prices) into the blockchain so smart contracts know when to pay you. Like the kid who peeks out the window and tells the smart contract it’s raining so it can pay out the “rainy-day” bet
