A token generation event is the transaction set that brings a token into existence and puts it in front of a market: the contract is deployed, supply is minted, allocations are sent to their destinations, vesting contracts are funded, and a pool or listing opens trading. It is an execution event, not a marketing one. Most of what people call TGE risk was decided months earlier and only becomes visible on the day.
Almost nothing about a TGE is reversible. Supply, allocation splits, vesting terms and the launch pool are all fixed by transactions that settle in minutes, and the market prices whatever those transactions produced. The window for changing any of it closes before the day starts.

The event is a deployment, not an announcement
Chainlink's definition is the plainest one in circulation: a TGE is the technical and operational process of creating and distributing a new digital asset on a blockchain.1 Tokenomist puts the market side next to it, describing the TGE as the moment a token is created, publicly distributed and begins trading, and the point at which cliff timers and supply mechanics start running.2
Both halves matter and teams tend to prepare for only one. The creation half is a set of transactions: deploy, mint, transfer, fund, seed. The distribution half is what a market does with the result. A project can execute the first flawlessly and still discover the second went badly, because the second is a consequence of allocation and float decisions made in a spreadsheet weeks earlier.
The framing we push clients toward is unglamorous. A TGE is the moment your token design stops being a document and starts being an obligation to holders. If the business underneath it does not generate value independently of the token, the TGE does not fix that. It just gives the problem a price.
What is frozen on the day, and what stays adjustable
Total supply and the mint logic are frozen unless the contract kept a mint role, in which case it is not really frozen and holders deserve to be told so. Allocation splits are frozen the moment the transfers settle. Vesting terms are frozen once the escrow contracts are funded, because changing them afterwards means either an upgrade path you disclosed or a migration nobody wants.
None of that certainty comes from the standard. EIP-20 specifies transfer and approval behaviour and says nothing about supply caps, mint authority, pausing or upgrades.5 Every one of those powers is a choice your implementation made, which is why the admin roles on the deployed contract are a diligence item and the standard name on the front page is not.
What stays adjustable is narrower than most teams assume: incentive programmes funded from an unlocked treasury, listing venues, market-making arrangements, and any emission schedule that was deliberately built with governance control. That last one is a design choice with a cost, since a supply parameter a DAO can change is a supply parameter the market has to price as uncertain.
BitGo's practitioner framing is the useful test here. A TGE is not defined by how many tokens exist; it is defined by how much supply enters the market, how much stays locked, and when future supply becomes available.3 Those three numbers are the deliverable. Total supply is a headline.
The float the market reads on day one
Float is the share of supply that is unlocked and tradeable when trading opens. It varies enormously across launches. Tokenomist's own summary of the range is that some tokens launch with under 5% float and others above 50%, and that each unlock event raises the number, with cliff unlocks capable of doubling or tripling effective float overnight.4
Low float is not automatically good design and high float is not automatically bad. What low float does is concentrate price sensitivity: a smaller tradeable base means each order moves further, in both directions, and it means every subsequent unlock lands as a proportionally larger supply increase against the base that existed before it. High float dilutes early price sensitivity and demands more capital in the pool to hold a given depth.
The design error is publishing a float number without decomposing it. Tokens sitting inside a liquidity pool count as circulating on most trackers and cannot be sold by anybody, because they are the counterparty to selling rather than a seller. Tokens held by buyers who paid full price behave differently from tokens airdropped at zero cost. Same headline, different launch.

The pool sets the price, and the arithmetic is unforgiving
Seeding a launch pool is a pricing act. You deposit a quantity of tokens and a quantity of a quote asset, and the ratio between them is the opening price. In a constant-product automated market maker, the product of the two reserves stays constant across every trade, which means depth and price impact are both fixed by what you deposited.
Work an illustration with round numbers. Total supply 60,000,000. Launch price $0.10, so fully diluted valuation is $6,000,000. You seed the pool with 6,000,000 tokens and $600,000, giving a reserve product of 3.6 trillion. Outside the pool, 1,200,000 tokens are unlocked and held by people who can sell.
Now sell all of them into that pool, ignoring fees. The token reserve rises to 7,200,000, so the quote reserve falls to 3,600,000,000,000 divided by 7,200,000, which is $500,000. The sellers collectively receive $100,000 and realise an average of $0.083 per token. Spot price finishes at 500,000 divided by 7,200,000, or $0.069, roughly 31% below the opening price. Two percent of supply moved the price by nearly a third.
Nothing in that paragraph is a forecast about any real token. It is division. The point is that the relationship between pool depth and sellable float is knowable before launch to the dollar, and a team that has not computed it has chosen a launch-day outcome without looking at it.
ICO, IEO and IDO are venues; the TGE is the event
These terms get used interchangeably and they are not interchangeable. The TGE is the generation and distribution of the token. An initial coin offering, an initial exchange offering and an initial DEX offering are three ways of selling part of it, and a project can run a TGE with none of them, distributing entirely by airdrop, grant or mining.
The distinction has practical consequences. A sale venue determines who is allowed to buy, what disclosure they get, what identity checks run, and whether an intermediary carries any of the compliance obligation. The TGE determines what exists and what unlocks. Confusing the two is how teams end up with a compliant-looking sale attached to a supply schedule nobody stress-tested.
Where a token is sold to buyers expecting a return from the team's future work, the securities analysis attaches to the transaction, not to the acronym used to describe it. The Howey test and the security versus commodity question are treated properly on their own pages, and that analysis belongs with counsel rather than a launch checklist.
Every clock in the design starts here
Cliffs, linear vests, emission schedules, staking reward curves and lockup expiries almost always measure from the TGE timestamp. That single shared origin is why cliff walls form: three buckets each given a twelve month cliff in three separate negotiations all break on the same day, because they were all measured from the same block.
It also means the unlock calendar is public information from day one. Anyone can read the vesting contracts, build the month-by-month release schedule and know exactly how much supply arrives in month thirteen. Treating that schedule as a surprise you can manage with messaging misreads who your counterparty is.
The useful consequence is that the whole supply path is modellable before launch. Build the monthly release table across every bucket, overlay it against the depth you plan to fund, and the difficult months identify themselves while the terms are still negotiable.
What we settle before a TGE
Six things, in this order. The total supply and whether any mint authority survives deployment. The allocation table, with every bucket's cliff and vest written against the same calendar so convergence is visible. The unlocked float at open, decomposed into who holds it and at what cost basis. The pool depth and the price impact of the full sellable float hitting it. The venue and who is permitted to buy there. And what the treasury funds in the first two quarters, since an incentive programme with no budget is a plan with no funding.
Reverse that order and you get the pattern we see repeatedly in diligence: a launch date chosen first, a valuation reverse-engineered to fit it, and an allocation table assembled to reach the valuation. The date is the cheapest variable in the list and it is the one teams refuse to move.
This page is design reference. It is not legal advice, and it is not a recommendation to buy, sell or hold anything. The token is infrastructure for a business. If the business is not creating value, a well-executed TGE only distributes that fact more widely.
Common questions
What is a token generation event?
A token generation event is the process of creating a new token onchain and distributing it, covering contract deployment, minting, allocation transfers, vesting funding and the opening of trading.1 It is also the moment cliff timers and supply mechanics begin running, which makes it the reference date for every unlock in the design.2 The event is operational rather than promotional.
What is the difference between a TGE and an ICO?
The TGE is the creation and distribution of the token. An ICO is one way of selling part of it. A project can run a TGE with no public sale at all, distributing through airdrops, grants or mining, and it can run a sale through an exchange or a decentralised exchange instead. The sale venue governs who may buy and what disclosure they receive; the TGE governs what exists and what unlocks.
What percentage of supply should be unlocked at TGE?
There is no industry answer, and anyone quoting one is guessing. Observed launches span a wide range, with some tokens opening under 5% float and others above 50%.4 The number that matters for your design is the relationship between sellable float and pool depth, which you can compute exactly. Model the full sellable float hitting your planned depth and read the price impact off the arithmetic.
Can tokenomics be changed after the TGE?
Some of it, at a cost. Total supply, allocation splits and funded vesting terms are effectively fixed once the transactions settle, and changing them means an upgrade path you disclosed or a migration holders have to accept. What stays adjustable is treasury spending, listing venues, market-making arrangements and any parameter you deliberately placed under governance control. Each governance-controlled parameter is one the market has to price as uncertain.
What goes wrong most often at a TGE?
A mismatch between sellable float and liquidity depth, decided weeks before launch and discovered on the day. The second most common is cliff convergence: several buckets given the same cliff length in separate negotiations, all measuring from the same TGE timestamp and therefore all unlocking together. Both are arithmetic problems that are free to fix before signing and expensive afterwards.
