An Initial Coin Offering (ICO) is a crypto-asset fundraising mechanism in which a project issues newly created tokens to investors in exchange for cryptocurrency or fiat capital, typically prior to or alongside the launch of the underlying protocol. ICOs were the dominant primary capital-formation vehicle for blockchain projects during the 2017–2018 cycle and remain a structural reference point for token issuance — though the regulatory landscape has materially constrained pure ICOs in favor of more compliance-aware variants.
The 2017–2018 ICO cycle raised over $20B in token sales globally, but also produced widespread securities-law enforcement: SEC actions against Telegram (TON), Kik (Kin), Block.one (EOS), Ripple (XRP), and dozens of smaller issuers established that most ICO tokens — when offered for capital formation with promises of network growth and price appreciation — meet the Howey Test and constitute unregistered securities. Settlements and rulings have produced substantial fines and rescission obligations.
Compliance-aware successors include: SAFT (Simple Agreement for Future Tokens) — a Regulation D-exempt instrument selling accredited investors the right to receive tokens at network launch; STO (Security Token Offering) — explicitly registered or exempt securities offerings with token wrappers; IEO (Initial Exchange Offering) — token sales through licensed exchange platforms that handle KYC and listing; IDO (Initial DEX Offering) — token launches on decentralized exchanges with permissionless participation; and airdrop-based distribution avoiding any sale and meeting eligibility criteria.
For Türkiye-based founders raising via token offerings, the SPK’s 2024 crypto-asset service provider framework brings token issuance and trading within Turkish regulatory perimeter for activities targeting Turkish residents. Cross-border token issuance typically structures through foreign foundations (Cayman, Switzerland, Singapore) with careful jurisdictional segregation of issuer, contributor, and platform activity.
