Tethers

Tethers are restraining lines or devices used to secure a person, animal, or object to a fixed point or another object. They are typically made from rope, chain, or similar materials and come in a range of sizes for different loads and environments. The verb tether means to fasten or secure with such a line or device.

Common uses include agricultural and livestock settings, where animals are tethered to posts or stalls; equestrian settings with lead lines; nautical environments where vessels, buoys, or gear are moored; and in aerospace contexts where astronauts or payloads are restrained during procedures or testing.

In technology, tethering describes sharing a device's internet connection with other devices. A smartphone or tablet can be tethered via USB, Bluetooth, or Wi‑Fi, enabling a computer or other device to access cellular data.

In finance and cryptocurrency, Tether is a brand of stablecoins, notably USDT, issued by Tether Limited. These tokens aim to be pegged to a fiat currency to provide price stability and liquidity in crypto markets. The issuer has faced scrutiny over reserve backing and auditing practices.

Safety and maintenance considerations include regular inspection for wear, fraying, or damage to lines; using appropriate anchor points and hardware; avoiding knots that can slip; and adhering to weight limits and applicable regulations in maritime, aviation, or wildlife contexts.
