The YLDX token contract owner is 0xaaE51e9F72cc278Cf6527C8380Ae94195Ebc7F42. Always verify addresses against this page and the official site before interacting. Note: the same SYLDX/crowdsale addresses may collide with unrelated tokens on other chains (e.g. a same-address "Staked RAA" on Base) — only the chains listed above are YLDX.

Verifying purchases on-chain
The crowdsale emits a purchase event you can index directly:
- Event topic:
0x9fa236593f411affe147142a606176190ea6b18be0643332f081175cfe608b6b - Decoded fields:
(receiver, tokenSpent, spent, boughtYLDX × 1e18)
Reading the spent field correctly. Its scale changed across the contract's life: early rounds recorded it as USD × 1e6, later rounds as native WETH wei (after an upgrade). To value a purchase in USD, compute boughtYLDX × active-round price (carry-forward by time), not the raw spent value. The contract's own totalSold() counter (164,918,582 YLDX) is the authoritative cross-check.
