According to official news, Tether has launched a developer grant program that will reward developers with USDT or Bitcoin for building localized AI and payment infrastructure. There is no total grant cap for this program, and rewards will be issued based on technical tasks and deliverables, with current individual bonuses ranging from $1,500 to $4,000.This funding focuses on Tether's open-source technology stack, including wallet infrastructure, browser extensions, e-commerce integration, and particularly supports its local AI platform QVAC. Tether stated that QVAC can run AI inference directly on the device locally, without relying on cloud servers, to reduce latency, costs, and data exposure risks.In addition, Tether will also promote the development of its Wallet Development Kit (WDK) ecosystem. This tool allows developers to directly embed self-custody wallets within applications, enabling local key generation, transaction signing, and asset transfers without relying on custodial services or third-party APIs.Tether CEO Paolo Ardoino stated that a significant amount of infrastructure still forces developers to rely on centralized platforms and data business models, and Tether hopes to fund systems that can "run locally, hold value directly, and have no external dependencies" to enter the market.

The founder of Binance, CZ, responded to early Bitcoin investor Davinci Jeremie regarding the "zero balance" experience of his multi-signature wallet, stating that if a wallet software upgrade changes the derivation path, it is "very bad and scary," referring to it as "self custody perks."Previously, Davinci pointed out that his 2-of-3 multi-signature wallet was unable to find the original address and balance despite using the correct private key due to a software change in the derivation path, and he ultimately relied on the saved old path to recover it. Several industry participants added that different standards (such as BIP44, BIP84, BIP86) can generate different addresses under the same mnemonic phrase, and if a wallet upgrade is not adequately prompted and migrated, it could lead to users misjudging the risk of asset loss.
