Builder+ by BTCS is our newly developed Ethereum and Binance chain block builders which utilize advanced algorithms to meticulously construct optimized blocks for on-chain validation designed to maximize validator earnings.
(Builder+ services are not accessible from or provided to the following countries: Cuba, Iran, North Korea, Russia, Syria, and Venezuela)
