Market cap (static): ~$4.7B

EIP standards (ERC-20, permit, proxies…)

Overview

Fastest-growing stablecoin of 2025 — launched by WLFI (Trump-family-linked project) in March 2025. Reached $2B+ market cap within months via Binance and Abu Dhabi MGX partnerships. Backed 1:1 by USD, US Treasuries, and cash equivalents, custodied by BitGo.

Features

Engineering-oriented breakdown of capabilities: standards, who they matter for, integration rationale, per-feature risks, and vetted external references (specs, docs, verified source).

Multi-chain from genesis
cross chain
BothVerify **official** contract addresses per chain before integration — placeholders in static data are not authoritative.Wrong address integration is total loss; phishing and fake tokens are likely for high-profile launches.

Technical notes

Standard ERC-20/BEP-20 with mint/burn/freeze admin. Always verify contract addresses on Etherscan and BscScan from official WLFI sources before any integration — do not use addresses from unofficial sources. Early-stage transparency — full due diligence recommended.

Integration notes

USD1 is early-stage with verify-before-ship contract hygiene: source canonical addresses from official WLFI channels only, and re-check before mainnet deployments.

Custody

BitGo custody and partner-led distribution dominate—plan integrations around issuer upgrade and freeze patterns typical of centralised stables.
