Streamflow NFT Locks, without the press-release fog
A time lock for one Metaplex Core NFT. The default is irreversible. Creation is free except for Solana network fees. That is the product. The rest is configuration.
Streamflow is a Solana token-distribution platform. Its public site lists vesting, airdrops, staking, and token locks. The product site is streamflow.finance; the app is app.streamflow.finance. NFT Locks extend that lock product from fungible tokens to Metaplex Core NFTs.
I have not locked an NFT on Streamflow. This article is a product explainer drawn from Streamflow’s own site, app, and documentation — not a walkthrough of a lock I created, and not financial advice.
A lock, not a drip
A Streamflow token lock holds assets until a scheduled date. Nothing vests in between. An NFT Lock applies the same binary rule to a single Metaplex Core NFT.
The holder chooses the NFT, an unlock date and time, and a recipient. The recipient can be a wallet address, a .sol name, a saved contact, or the connected wallet. When the unlock time arrives, the NFT is sent to that recipient automatically.
If the contract behaves as documented, the NFT is not sitting in the holder’s wallet with a sticky note. It is in the lock until the clock runs out, then it moves.
Default: you cannot take it back
Streamflow’s default NFT Lock is irreversible. Before unlock you cannot reclaim the NFT and you cannot redirect it. That is the setting you want if the point is a hard public commitment — a team allocation, an escrowed transfer, or a personal rule that this piece will not move before a date.
Two optional permissions can be turned on at creation:
- Allow cancellation — the creator can return the NFT early.
- Allow recipient change — the destination can be updated while the lock is still active.
Those settings live on-chain. Anyone who inspects the lock can see whether cancellation or recipient changes were enabled. The flags are part of the public record, not a hidden admin switch.
Cost and a public proof link
Streamflow says creating an NFT Lock is free at the product level. You still pay Solana network fees. I am not restating Streamflow’s fee table for fungible token locks or vesting; those are separate products.
Each lock produces a public proof link. Streamflow says that link can be checked on Solscan or Solana Explorer. That is the practical difference from a screenshot in a group chat: a third party can look up the NFT, the unlock time, the recipient, and the permission flags.
Audits, in Streamflow’s words
Streamflow states that its contracts have been audited by FYEO and OPCODES. I have not independently reviewed those reports. An audit is a review of specific code at a point in time. It is not a guarantee that you chose the right recipient, the right date, or the right permission flags.
Streamflow’s site states TVL of $365M+, 1.3M+ users, and 40K+ projects. Those are the company’s own figures. I am repeating them as homepage copy, not as numbers I verified.
What this is for — and what it is not
If the product works as documented, an NFT Lock is useful for a timed transfer of one specific NFT to a known wallet; a public commitment that a particular NFT cannot move until a date; escrow-style deals where both sides can inspect the on-chain settings; or a personal hold if you want the chain, not your later mood, to enforce the date.
It is not a substitute for checking the recipient twice. It is not evidence that an NFT collection is a good purchase. And “locked” does not always mean “cannot come back.” That depends on whether cancellation was enabled.
I am not recommending that you lock anything. Unlock dates, recipient addresses, and the irreversible default are user-configured. If you might need the NFT back, enable cancellation before you confirm — the default will not let you. If you are relying on someone else’s lock, read the on-chain settings, not the announcement.
