When you apply for an IDO whitelist, one of the most practically important questions is: what type of allocation system does this IDO use? The answer determines how you should prepare, what advantages you have or don't have, and whether speed or luck is more important than capital. Two dominant models define the IDO allocation landscape: FCFS (First Come, First Served) and Lottery.
What Is FCFS (First Come, First Served)?
FCFS allocation means the IDO opens at a specific time and eligible whitelisted wallets can purchase tokens until the hardcap is reached. The first wallets to submit transactions get tokens; those who submit transactions after the hardcap fills receive nothing (and their transactions are automatically refunded or rejected). In practice:
- Technical speed matters: faster wallets, better internet connections, and prepared scripts give an advantage
- Gas competition: on Ethereum, FCFS sales often see gas wars where participants bid high gas fees to prioritise their transaction
- Full allocation: if you get in, you typically receive your maximum eligible allocation — not a lottery portion
- No waiting: you know immediately whether you participated successfully
FCFS suits investors who: are technically prepared (have good internet, know how to increase gas), prefer certainty over probability, and don't mind the competitive element.
What Is Lottery Allocation?
Lottery allocation runs before the token sale: eligible participants (who have passed KYC, staked launchpad tokens, or met other criteria) are randomly selected for guaranteed or weighted allocation. Winners can then purchase during the sale window without competition. Losing lottery participants cannot buy in the primary sale.
Lottery models used by major platforms:
- Pure lottery: Each eligible wallet has equal odds regardless of staking amount (common for very small tier positions)
- Weighted lottery: Higher staking = more lottery tickets = better odds (common approach on DAO Maker, Polkastarter)
- Guaranteed allocation for top tiers: The highest launchpad tier gets guaranteed allocation; lower tiers enter a lottery (DAO Maker, Binance Launchpad mechanics)
Lottery suits investors who: prefer equal opportunity over technical speed, are comfortable with uncertainty before the sale, and participate consistently across many IDOs to average out lottery variance.
Hybrid Models
Most major launchpads use hybrid systems: guaranteed allocation for top-tier stakers, lottery for mid-tiers, and FCFS for any remaining allocation after guaranteed/lottery rounds close. Binance Launchpad uses a pro-rata commit model (all BNB committed is proportionally allocated) — technically FCFS in that the commitment window is open, but anyone can participate regardless of speed.
FCFS vs. Lottery: Which Is Better?
| Factor | FCFS | Lottery |
|---|---|---|
| Capital requirement | None beyond eligible stake | Staking for better odds |
| Technical advantage | Yes — speed matters | No — randomised |
| Outcome certainty | Known instantly | Known after draw |
| Fairness to small investors | Less fair (speed advantage) | More fair (equal odds per ticket) |
| Best strategy | Prepare technically | Consistent participation |

Glossary
- FCFS (First Come, First Served)
- An allocation model where the earliest transactions in an IDO receive tokens until the hardcap is reached. Speed determines success.
- Lottery Allocation
- A random selection process determining which eligible participants can purchase in an IDO. Reduces technical speed advantage; increases variance.
- Hardcap
- The maximum amount an IDO will raise. In FCFS models, transactions after hardcap is reached are automatically rejected or refunded.
- Pro-Rata
- Proportional allocation — each participant receives tokens proportional to their committed amount relative to total committed. Used by Binance Launchpad.
