What Is the Difference Between Token Burn and Token Lock?
Token burns and token locks both reduce circulating supply — but they're completely different in permanence and trustworthiness. Learn which one actually protects you.
Two mechanisms that look similar but work very differently
In crypto marketing materials and community announcements, "token burn" and "token lock" are sometimes used interchangeably — as if both are equivalent demonstrations of the team's commitment to reducing supply and supporting price. They are not equivalent. The difference between a token burn and a token lock is the difference between permanent and temporary, irreversible and reversible.
What a token burn is
A token burn is the permanent, irreversible destruction of tokens. On Solana, burning tokens means transferring them to a designated burn address — sometimes called a "dead wallet" — from which they can never be retrieved. The Solana network's SPL Token program has a built-in burn instruction that permanently removes tokens from circulation by reducing the token's total supply count on-chain.
When tokens are burned, the total supply recorded on the blockchain decreases. This reduction is:
- Permanent: no one can undo a burn transaction
- Verifiable: the burn transaction is on-chain and visible to anyone
- Trustless: you don't need to trust the team's future behavior — the tokens are gone
What a token lock is
A token lock means that tokens are placed in a smart contract (a vesting or locking contract) that prevents them from being transferred until a specified condition is met — usually the passage of a defined time period. Common lock platforms on Solana: Streamflow, Vaultx, and Raydium's native lock function.
When tokens are locked: they are temporarily inaccessible, they remain in existence (total supply is unchanged), and the future unlock creates supply pressure.
Why the difference matters for investors
When a team announces "we've locked 500 million tokens," the correct response is: "locked until when, and what happens when they unlock?" If 500 million tokens are locked for 3 months and then become freely tradeable, the circulating supply increases by 500 million in 3 months — significant potential sell pressure.
When a team announces "we've burned 500 million tokens," those tokens are gone forever. The total supply is permanently 500 million lower. No future unlock event will create sell pressure from those tokens.
| Factor | Token burn | Token lock |
|---|---|---|
| Permanence | Permanent — irreversible | Temporary — expires on schedule |
| Effect on total supply | Reduces total supply permanently | No change to total supply |
| Future sell pressure | None — tokens are destroyed | Yes — at lock expiry |
| Trust requirement | None — trustless on-chain action | Low — trust lock contract is genuine |
The "sent to dead wallet" distinction
Some projects claim to "burn" tokens by sending them to a wallet with an address they don't control — sometimes called a "dead wallet." This is functionally equivalent to a burn for practical purposes — the tokens can never be accessed — but it is technically different from the SPL burn instruction, which actually reduces the total supply count. When evaluating a "burn," check whether total supply on Solscan decreased (true burn) or tokens were merely sent to an inaccessible address.
