Self-custody, swaps and bridges — explained properly
Practical guides on seed phrases, send/receive, exact wallet errors, Exchange (swap & bridge), and security — written by the people who build one. No hype, no affiliate links.
Swap & Bridge learning hub
Fifteen focused guides plus the how-to for GaurdWallet Exchange v0.2.1 — LI.FI on EVM, Jupiter on Solana, honest limits on BTC/LTC/TRON and Solana cross-chain.
How to swap and bridge in GaurdWallet
Same-chain swaps, EVM bridges, Solana swaps via Jupiter — slippage, exact approvals, and what to verify before you sign.
Swap vs bridge in crypto
Same-chain token exchange vs cross-chain moves — costs, risks, and which button to use in Exchange.
Crypto slippage explained
Tolerance presets, minimum received, failed trades, and an offline estimator — not fake live rates.
ERC-20 token approvals
Exact-amount vs unlimited spend, approve phishing, and why GaurdWallet defaults to tighter allowances.
How LI.FI bridging works
Routing across bridges and DEXes, quote fields that matter, and how GaurdWallet proxies aggregator calls.
Jupiter Solana swaps
Quote → sign locally on Solana via Jupiter — same-chain only in Exchange v0.2.1.
Gas fees when swapping and bridging
EIP-1559, L2 fees, destination gas for bridges, Solana priority fees — plus an offline budget widget.
Bridge security checklist
Interactive pre-flight checks before you sign a cross-chain route — phishing, networks, pending status.
Bridge USDC across EVM chains
Stablecoin corridor steps in GaurdWallet, native vs bridged USDC caution, and test amounts.
Ethereum to Base bridge guide
L1→L2 corridor: gas differences, ETH and ERC-20, timing expectations in Bridge mode.
DEX swap best practices
Size, slippage, approvals, scam tokens, and reviewing the quote UI before you confirm.
Price impact vs slippage
Two different numbers on the quote screen — when high impact means you should shrink the trade.
Why swap quotes expire
Route TTL, market movement, refresh UX, and why you must not re-send a still-pending bridge.
Non-custodial swap safety
Keys stay local; protocol risk does not. Exact approvals, phishing, and honest unaudited-app limits.
Swap & bridge glossary
Definitions for slippage, toAmountMin, approvals, aggregators and more — linked into the cluster.
When to swap or bridge
Decision paths for common goals — and clear unsupported cases (BTC/LTC/TRON, Solana↔EVM).
What is a non-custodial wallet? Self-custody explained
What "non-custodial" actually means, how one seed phrase becomes keys and addresses on fifty networks, and what you sign up for when nobody holds your coins for you.
How to store USDT without KYC
Holding your own USDT requires no account, no e-mail and no identity check. How that works, which networks carry USDT, and where KYC still applies.
TRC-20 vs ERC-20 USDT: fees, speed and which to choose
Same dollar, different rails. How USDT on TRON differs from USDT on Ethereum — fees, confirmation times, address formats — and how not to send it to the wrong network.
How to import your MetaMask seed phrase into another wallet
Wallets built on the same standards are interchangeable. Step-by-step migration, why the same 12 words give the same addresses everywhere, and mistakes that cost funds.
Are browser extension wallets safe?
An honest threat model: phishing, wallet drainers, fake extensions, malware — what an extension wallet protects you from, what it can't, and the habits that matter.
12 vs 24 word seed phrase: what actually matters
128 vs 256 bits of entropy sounds dramatic. In practice neither will ever be brute-forced — seed phrases fail for entirely different reasons. How to choose, honestly.
How to add a custom EVM network to your wallet
Chain ID, RPC URL, native symbol — what each field means, where to find trustworthy values, what a malicious RPC can and cannot do, and a two-minute setup walkthrough.
Trading learning hub
Cluster index for the trading terminal: non-custodial basics, chart reading, order types, sizing, leverage and honest derivatives limits.
What is non-custodial trading? No account, no KYC
How a non-custodial trading terminal routes orders through contracts you sign yourself, and how that differs from a centralized exchange account.
How to start trading from your wallet
Fund the wallet, open Trade, pick a pair, review the quote, confirm and sign — the full first-trade walkthrough plus a pre-trade checklist.
How to read candlestick charts
Open, high, low, close, wicks and body color — a practical, beginner-level guide with an interactive labeled diagram.
Market vs limit orders: which should you use?
Fill now at the available price, or wait for your price — the core tradeoff behind every order type, plus a short quiz.
Position sizing: how much of your portfolio to risk
How much a single trade should ever be able to lose, an honest risk-per-trade framework, and a position-size calculator.
Long vs short: betting on prices going up or down
Going long vs going short in plain language, with an illustrative payoff slider and honest scope on what GaurdWallet supports today.
Leverage and liquidation price, explained simply
Why leverage multiplies gains and losses, what a liquidation price means, and a simplified estimator — not offered in GaurdWallet today.
Perpetual futures and the funding rate explained
No expiry, tracked via periodic payments between longs and shorts — how perpetual futures stay tethered to spot price.
Spot vs perpetual futures: what is the difference?
Ownership vs synthetic exposure, leverage, funding costs and liquidation risk — compared side by side.
Liquidity and slippage for traders
Pool depth and price impact for traders actively picking pairs and sizing orders, plus an offline minimum-received calculator.
Import a Phantom seed phrase
Same 12/24 words, Phantom-compatible Solana path, then multi-chain addresses from one vault.
Import a Trust Wallet seed phrase
Standard EVM path like MetaMask — verify the 0x address, then turn on BNB Chain in Settings.
Export a Coinbase Wallet seed
Self-custody app vs Coinbase.com exchange — only the app phrase imports. Verify the 0x address.
OKX Wallet to self-custody
Separate the OKX exchange login from the OKX Wallet phrase. Import or withdraw — never both mixed up.
Exodus wallet alternative
Honest alternative: same seed only if Exodus showed BIP-39. Verify each chain; some assets will not map.
MetaMask vs GaurdWallet
Same EVM seed path, extra chains, LI.FI/Jupiter Exchange, unpublished extension — honest table.
Phantom vs GaurdWallet
Same Solana path, extra chains, Jupiter in Exchange, no SOL↔EVM bridge — comparison table.
Rabby Wallet vs GaurdWallet
EVM simulation vs multi-chain vault. Same seed path; we are not Rabby and not store-listed yet.
This is not a valid BIP-39 recovery phrase
Literal Import error: wordlist + checksum. Diagnose 11 words, typos, passphrase wallets — offline.
Insufficient funds including the network fee
Literal Send error: amount + fee > native balance. ERC-20 does not pay its own gas.
Invalid address for this network
Literal send.invalidAddress: EIP-55 mixed-case, wrong ecosystem prefix, truncated hex.
Could not fetch a quote
Literal exchange.error.quote: proxy empty, unsupported corridor, or temporary aggregator gap.
Solana bridges are not available yet
Literal exchange.error.solBridge. Jupiter same-chain only in v0.2.1.
Wrong password. Try again.
Literal unlock.wrongPassword. Same throw as a corrupted vault. Reset erases this device copy.
Couldn't read this contract
Literal settings.tokens.fetchFailed. Fetch is chain-specific — USDT Ethereum ≠ USDT TRON.
RPC answered with the wrong chain id
Literal settings.networks.probeMismatch. Built-in chain-id table plus the add-anyway risk.
EIP-55 checksum address
Same keccak mixed-case rule as validateAddress. Live encoder in the tab — no RPC.
Wei / gwei / ether converter
Offline 1e18/1e9 converter for reading fees. Wallet still shows live EIP-1559 tiers.
BIP-44 derivation paths explained
Literal HD paths from the keyring — Phantom/MetaMask/TronLink compatible where we claim it.
XRP destination tag in a wallet
r-address receive works. Exchange deposits that need a tag: do not Send from GaurdWallet yet.
TRON energy and bandwidth fees
Energy vs bandwidth vs TRX burn. Wallet estimates live; widget is arithmetic only.
Native USDC vs bridged USDC
Ticker collision: native Circle USDC vs bridged. Match the contract Exchange quoted.
Bitcoin SegWit vs legacy addresses
bc1q BIP-84 vs 1… / 3…. Send-to-invoice vs what this wallet derives.
Solana Token-2022 in a wallet
ATA + Token-2022 program id. Adapter support, Jupiter same-chain, no SOL bridge.
Litecoin ltc1 address format
BIP-84 ltc1 Receive, not legacy L…. Same SegWit idea as Bitcoin bc1.
How to send Ethereum
Send ETH on Ethereum mainnet: EIP-55 recipient, EIP-1559 tiers, insufficient-funds check.
Receive Bitcoin to a bech32 address
Copy bc1q from Receive, tell the sender Bitcoin mainnet, keep sats for the next fee.
Receive USDT on TRON (TRC-20)
T-address Receive, TRC-20 only. ERC-20 USDT to this address is lost. Keep TRX for energy.
Send USDT to Binance
CEX deposit: match TRC-20/ERC-20/BEP-20. Test amount first. GaurdWallet is not Binance.
EIP-6963: connect a wallet to a dApp
Multi-wallet discovery. Extension built, not store-listed. Web wallet is live for send/swap.
