Tether, a prominent cryptocurrency issuer, has made its Wallet Development Kit (WDK) open-source, empowering developers to build secure, cross-platform digital wallets. This move promises to reshape the landscape of self-custody by enabling widespread adoption of non-custodial wallets and driving increased usage of Tether’s USDT, Bitcoin (BTC), and Ethereum (ETH). The WDK supports various cryptocurrencies like BTC, ETH, and TON and is expected to foster greater interoperability across multiple chains. This latest initiative builds on successful models from established players in the space, such as MetaMask and Coinbase SDKs, paving the way for a significant expansion of DeFi and wallet adoption.
