Intro
Staking has become a mainstream way to earn passive income in crypto. In 2025, staking remains one of the most accessible tools for long-term investors: instead of buying power-hungry mining rigs, you lock tokens to help secure a blockchain and earn rewards in return. This guide explains how staking works, realistic yields this year, how to choose a method (solo, delegated, or liquid staking), and a practical tip for safely sharing staking addresses using QR codes.
Staking transforms token ownership into an active contribution to network security and governance. As many major networks (Ethereum, Cardano, Polkadot, Solana, TON) continue to rely on or expand PoS variants, staking offers predictable token yield — while still exposing you to market volatility. For many users, staking is a way to grow holdings without constantly trading.
Proof-of-Stake (PoS) replaces energy-intensive mining with a system where validators are selected based on the amount they stake. The core steps:
Lock tokens in a validator deposit or staking contract.
Be selected to propose or validate blocks (selection typically weighted by stake).
Earn rewards in newly minted tokens + transaction fees.
Risk penalties: poor behavior or downtime can lead to slashing—partial loss of your stake.
Run your own validator node. Pros: highest reward share, full custody. Cons: technical setup, uptime responsibility, high minimums on some chains (e.g., 32 ETH).
Delegate tokens to a reputable validator and earn a share of rewards after the validator’s commission. Low technical entry, funds often remain in your wallet (chain dependent).
Lock tokens on a platform and receive a tokenized receipt (e.g., stETH or equivalent) that accrues rewards and can be used in DeFi. Exchanges offer custodial staking with convenience but require trust in the custodian.
APYs vary with network parameters, percent staked, and fees. Typical ranges (ballpark estimates):
Ethereum (ETH): ~3%–5% (via pools/LSTs)
Cardano (ADA): ~3%–4%
Polkadot (DOT): ~8%–12%
Solana (SOL): ~6%–8%
Toncoin (TON): ~3.5%–5%
Important: APY is paid in native tokens — fiat returns depend on the token price movement.
If you stake 10 ETH at 4% APY and ETH falls 50% in fiat, you still increase ETH holdings (to 10.4 ETH) but your fiat value drops substantially. Staking cushions token loss slightly but does not remove market risk. Think of staking as “earning more of the token,” not as a fiat-safe yield.
Validator choice: pick validators with strong uptime, transparency, and low history of slashing.
Diversify: split stake across validators and chains to reduce single-point failure risk.
Watch lockups: plan for unbonding periods (some networks require weeks).
Custody tradeoffs: exchanges are convenient but you surrender private keys. Liquid staking adds smart-contract risk.
A common practical need: share your staking pool, donation address, referral link, or staking guide with followers or conference attendees without typing long addresses. QR codes are perfect for this — they reduce copy/paste errors and speed adoption.
How to use QR codes for staking:
Create a QR code that encodes your wallet address or staking pool link.
Print it on business cards or slides at meetups.
Embed a QR linking to a step-by-step staking tutorial or your delegation page.
For liquid staking receipts (e.g., stETH tokens), use QR codes to share the contract address or documentation page.

Q1: Is staking guaranteed income?
A1: No — staking gives token yield, but fiat returns depend on market price movement.
Q2: Can I lose staked tokens?
A2: Rarely, but misbehavior, slashing, smart-contract bugs or custodial failures can cause losses.
Q3: How do QR codes help with staking?
A3: QR codes let you share wallet addresses, referral links or tutorials quickly and safely—reducing errors when users copy long addresses.
