Tether CEO Paolo Ardoino has announced that self-custody wallet creations built using the company’s Wallet Development Kit have surpassed 100,000, signaling growing developer adoption of the stablecoin issuer’s open-source infrastructure tooling. Ardoino shared the milestone on his X account, framing it as a measure of wallet creations rather than active users or transaction volume. The figure represents the number of self-custody wallets that have been spun up using WDK as the underlying framework.
