The XRP Ledger is a public blockchain that has been running continuously since 2012. You don't need to know how it works under the hood to use Gopnik responsibly, but five facts will save you from real, common mistakes.
1. Every account costs 1 XRP — the reserve
You can't have a useful XRPL account with zero XRP. The protocol locks 1 XRP per account as a base reserve and an additional small amount per object you own on the ledger (a trustline, an NFT, an offer, an escrow). This is anti-spam, not a fee. The XRP isn't burned — it's just unmovable until you delete the account.
Practical impact: if a friend sends you 0.5 XRP to your fresh wallet, the transaction fails because there's not enough to fund the reserve. Always make sure a brand-new wallet receives at least the reserve amount on its first deposit.
2. Transactions cost almost nothing — and they're irreversible
A typical XRPL transaction costs a fraction of a cent in fees and settles in roughly 3–5 seconds. There is no chargeback, no support hotline, no "are you sure?" once a validated ledger confirms it. The ledger is the source of truth, and it does not negotiate.
This is what makes self-custody both powerful and dangerous. There's no bank to call when you send to the wrong address.
3. Trustlines — the "I accept this token" handshake
XRPL has native support for issued tokens (also called IOUs). To hold any token other than XRP itself, you must first open a trustline to the issuer. This is a small one-time setup transaction that says "I am willing to be a creditor of this issuer up to this amount."
Why this matters: trustlines occupy a reserve slot. Opening fifty random trustlines costs you reserve XRP you can't spend, and exposes you to fifty different issuers' counterparty risk. Be deliberate.
4. The DEX is built in — and it's where the AMM lives
Most blockchains add decentralised exchanges as smart contracts on top. XRPL has the order book and an automated market maker in the protocol itself. That means liquidity is shared across the whole network, fees are tiny, and offers settle atomically. Gopnik's swap surface uses both order book and AMM paths and shows you which path was taken.
5. Memos are public — and forever
Anything you put in a transaction's Memo field is visible to the entire world, immutable, and indexed by every block explorer. Don't put email addresses, real names, or anything you wouldn't write on the side of a building. "Permanent" really does mean permanent here.
What this means for you as a Gopnik user
- Fund new accounts with at least 2 XRP the first time, leaving 1 XRP above the reserve so the account is actually usable.
- Verify every recipient address character by character before signing. The check digit at the end catches most typos but not all.
- Don't open trustlines you can't justify.
- Treat memo fields as a public bulletin board.
