How an IDO distributes allocation is one of the most important factors for investors — it determines whether you get in at all, how much you can invest, and whether your strategy (speed, luck, or capital commitment) is rewarded. The three primary IDO allocation models have distinct mechanics, advantages, and failure modes.
FCFS (First Come First Served)
Mechanics: The sale opens at a specific time. The first transactions to reach the contract receive allocation until the hardcap is filled. No pre-registration required — just be first.
Advantages: Simplest mechanic. No staking requirement — anyone can participate. No lottery uncertainty — if you're fast enough, you're in.
Disadvantages: Heavily favours bots and traders with fast RPC endpoints, low-latency connections, and gas bidding strategies. Human participants consistently lose to bots in popular FCFS IDOs. Creates poor distribution — a handful of bots capture most allocation. In 2026, pure FCFS is rarely used for the primary allocation on quality launchpads.
Who it benefits: Technical traders with bot automation, high gas bidding capability, and fast blockchain node access.
Lottery System
Mechanics: Pre-registered eligible investors enter a lottery draw. Winners (randomly selected) receive guaranteed allocation in the sale. Non-winners don't participate in this specific IDO. Used by Polkastarter's mid-tier participants.
Advantages: Eliminates bot advantage — randomness is unaffectable by technical speed. Provides fair access across a diverse pool of eligible participants. Allows small investors to participate (lottery win provides full mid-tier allocation regardless of staking amount above minimum).
Disadvantages: Pure luck — high-quality research and conviction doesn't help if you lose the draw. Creates uncertainty — you can't plan position sizing until lottery results are known. Emotional frustration from losing draws on projects you've thoroughly researched.
Who it benefits: Mid-tier stakers willing to accept outcome uncertainty; investors with diversified launchpad participation across many platforms to average out individual lottery results.
Guaranteed Allocation
Mechanics: Investors who stake above the minimum threshold receive guaranteed allocation proportional to their staking size. Used by: DAO Maker (top tiers), Kommunitas (all tiers — tier-less proportional), Binance Launchpad (proportional BNH subscription).
Advantages: Predictable — you know before the sale whether you'll get allocation. Scalable — more capital = proportionally more allocation. Rewards committed, long-term launchpad community members over casual participants.
Disadvantages: Favours capital — larger capital gets better absolute allocation. Minimum staking requirements create access barriers for small investors. Launchpad token price risk during staking period.
Who it benefits: Serious investors with medium-large capital who want predictable, scaled allocation as part of a systematic strategy.
Hybrid Systems
Most major launchpads use hybrid models: guaranteed allocation for highest stakers, lottery for mid-tier, and FCFS for remaining unsold supply. Kommunitas's IKO model is the most investor-friendly: guaranteed allocation for everyone who stakes any amount (proportional to stake), eliminating lottery uncertainty entirely.

Glossary
- FCFS (First Come First Served)
- An allocation model where the first transactions to reach the contract receive tokens until supply is exhausted — no pre-registration required but heavily bot-favoured.
- Lottery Draw
- Random selection among pre-registered eligible investors for guaranteed sale access — prevents bot advantage at the cost of outcome certainty.
- Whitelist
- The pre-approved list of wallet addresses eligible to participate in an IDO — typically generated from lottery draws or guaranteed allocation tier membership.
