Solana supports decentralized exchanges, lending markets, staking products, derivatives and other financial applications. Its base transaction fee is paid in SOL and can include an optional priority fee. Low fees make frequent interactions practical, but they do not make a protocol safe or a displayed yield dependable.
The original version of this guide used unsourced TVL, user, revenue and APY numbers; promoted leveraged products; and told Indian readers how to bypass centralized controls. Those claims have been removed. This version explains how the main protocol types work and which evidence to check before depositing funds.
How Solana DeFi transactions work
Solana stores state in accounts and executes instructions through on-chain programs. A transaction can contain multiple instructions that succeed or fail atomically. Wallets request signatures for those instructions, so the approval screen—not the website button label—is the actual action being authorized.
Fees have two main components: a base fee per signature and an optional priority fee determined by the requested compute budget. A transaction can still fail or arrive too late during congestion. “Low fee” is not the same as guaranteed execution or best price.
Before signing, inspect:
- the domain and connected application;
- assets and amounts leaving the wallet;
- minimum amount expected from a swap;
- accounts or authorities being created;
- token approvals and program addresses;
- priority fee and total network cost;
- whether the transaction simulation succeeded.
Use a small test transaction when interacting with a new application.
Decentralized exchanges and routing
Automated market makers such as Raydium, Orca and Meteora maintain pools in which prices respond to trades and liquidity. Jupiter routes swaps across available sources to seek a better quoted result.
An aggregator does not remove execution risk. A route can touch several programs and tokens. The final result depends on liquidity, slippage settings, priority fees, token transfer rules and whether the transaction lands before the quote expires.
Check these fields:
| Field | What it tells you |
|---|---|
| Price impact | Estimated change caused by the order |
| Minimum received | Worst permitted output under slippage setting |
| Route | Pools and programs the trade will use |
| Token mint | Exact asset, not its name or symbol |
| Liquidity depth | Whether the displayed price can absorb the order |
Fake tokens can copy a legitimate symbol. Verify the mint address from the issuer or a trusted registry.
Liquidity provision
Liquidity providers deposit assets into pools and may receive a share of swap fees or token incentives. Returns depend on actual volume, fee tier, price range, inventory changes and reward emissions.
The term “impermanent loss” can be misleading because the economic loss becomes real when a position is withdrawn. In a two-asset pool, rebalancing can leave the provider holding more of the asset that fell and less of the one that rose. Concentrated liquidity can stop earning fees when price leaves the selected range.
A high displayed APY may be annualized from a brief period or paid in a token whose price is falling. Separate:
- fees paid by traders;
- rewards emitted by the protocol;
- changes in the deposited assets;
- gas and rebalancing costs;
- the value of any unclaimed reward token.
Lending and borrowing
Lending protocols such as Kamino let users supply assets and allow borrowers to take overcollateralized loans. Rates vary with utilization. Suppliers face contract, oracle, liquidity and bad-debt risk in addition to the price risk of the deposited token.
Borrowers face liquidation when collateral value or account health falls below required limits. Liquidation can occur rapidly and may include penalties. A strategy that loops borrowed funds into more collateral increases leverage even if marketed as “multiply” or “enhanced yield.”
Before borrowing, document the liquidation threshold, oracle source, interest-rate model, withdrawal liquidity and behavior during network congestion. Leave a buffer for price and interest changes; the interface’s current health number is not a guarantee.
Native and liquid staking
Native SOL staking delegates stake to a validator. Liquid-staking protocols issue a receipt token representing a claim related to staked SOL. That token can be transferred or used in other applications.
Liquid staking adds layers beyond validator performance:
- smart-contract and governance risk;
- price divergence between the receipt token and SOL;
- liquidity needed for an immediate exit;
- validator selection and concentration;
- integration risk when the receipt token is used as collateral.
Using a liquid-staking token in a lending market does not create “double yield” without extra risk. It combines staking exposure with the risks and economics of the second protocol.
Perpetual futures and leverage
Perpetuals allow price exposure without an expiry date, using collateral and periodic funding or similar mechanisms. They can amplify gains and losses. Liquidation can occur before an investor’s long-term thesis has time to work.
Decentralized derivatives are not automatically permissionless in every legal sense. Interfaces can restrict jurisdictions, and users remain responsible for local law, tax and reporting. Do not use a protocol to evade KYC, sanctions or product restrictions.
Review oracle design, insurance funds, liquidation rules, auto-deleveraging, counterparty structure and the difference between on-chain program risk and the website operator.
How to interpret TVL and volume
Total value locked is a snapshot of assets attributed to protocol contracts. It can rise because token prices rise, because users borrow and redeposit the same value, or because an aggregator counts exposure differently. It is not revenue, customer deposits under bank protection or proof of solvency.
Trading volume also needs context. High volume can produce fees, but it may be incentive-driven, concentrated in risky tokens or calculated differently across data providers.
For durable analysis, compare:
- TVL in both dollars and native units;
- fees paid by users and revenue retained by the protocol;
- incentive emissions;
- active borrowers or traders over several months;
- liquidity concentration and whale exposure;
- audited contract versions and incident history.
Never combine statistics from different dates into one ranking.
Protocol due-diligence checklist
Code and control
- Are the exact deployed programs verified and audited?
- Can an administrator pause, upgrade or move funds?
- Is there a timelock or multi-signature control?
- Does an audit cover the current version?
Economic design
- Who pays the yield?
- What happens when rewards end?
- How concentrated are deposits and borrows?
- Which oracle and liquidation mechanism protect solvency?
Operations
- Has the protocol disclosed incidents and reimbursements?
- Is the official domain easy to verify?
- Are documentation, status and support channels current?
- Can users exit during stress without excessive slippage?
Personal security
- Use a separate wallet with limited funds for new protocols.
- Keep seed phrases offline and never enter them into a website.
- Verify transaction details and hardware-wallet screens.
- Bookmark official domains and avoid search advertisements.
Tax and access for Indian users
Swaps, rewards, liquidations and transfers can each create records needed for Indian VDA tax reporting. The legal characterization of DeFi income and the mechanics of Section 194S can depend on the transaction and parties involved. A wallet history alone may not capture rupee values, acquisition cost or off-chain transfers.
Keep contemporaneous exports and transaction hashes, and use our India crypto tax guide as general background. Complex activity may require a chartered accountant familiar with virtual digital assets.
Bottom line
Solana’s architecture and fee model support a broad DeFi ecosystem, but protocol risk is separate from network speed. A swap aggregator can improve routing; a lending market can match borrowers and suppliers; and a liquid-staking token can make a staked position transferable. None guarantees a return.
Trace where yield comes from, inspect every transaction, model liquidation and slippage, and assume that smart contracts, interfaces and assets can fail independently.
