Wrapped SOL (wSOL)
An SPL-token version of SOL with a 1:1 peg, required for interacting with certain Solana DeFi protocols that use SPL standards.
Wrapped SOL (wSOL) — Wrapped SOL (wSOL) is an SPL token representation of native SOL on the Solana blockchain. Since Solana programs interact with SPL tokens (Solana's token standard), native SOL must be wrapped into the SPL format to be used in DeFi protocols, DEX swaps, and smart contract interactions. Wrapping and unwrapping is instant and 1:1.
What Is Wrapped SOL?
Native SOL exists as the balance of a Solana system account, but DeFi programs expect SPL tokens. Wrapped SOL bridges this gap by depositing native SOL into a token account that holds it as an SPL token. The process is seamless — most wallets and DEXs handle wrapping automatically when you trade or provide liquidity with SOL.
Why Wrapping Is Needed
Solana's token programs (SPL Token and Token-2022) define a standard interface for all fungible tokens. DEX programs like Raydium and Orca are built to interact with this standard interface. Wrapped SOL allows native SOL to conform to this interface, enabling it to be traded, pooled, and used as collateral just like any other SPL token.
Wrapped SOL in Practice
When using a DEX aggregator like Jupiter to swap SOL for another token, the interface automatically wraps SOL, executes the swap, and returns the output token. Users rarely need to manually wrap SOL. However, developers building on Solana must account for the wrapping step in their program logic. OpenLiquid handles SOL wrapping automatically during volume-generation sessions on Solana.

Common questions about Wrapped SOL (wSOL) in cryptocurrency and DeFi.
Wrapped SOL represents native SOL 1:1 in SPL token format. It has the same value but exists as a token account rather than a system account balance. Wrapping and unwrapping is instant with no fees beyond the transaction cost.
Usually not. Most DEXs, wallets, and DeFi protocols handle wrapping automatically. You may need to manually wrap SOL if interacting with programs that only accept SPL tokens or when providing liquidity to pools that require the wSOL token specifically.
Wrapping SOL costs a small transaction fee (under $0.01) plus the rent-exempt deposit for the token account (approximately 0.002 SOL). The rent deposit is returned when you unwrap and close the token account.
