Introducing Programmable Addresses: One Address. Any Chain.

Eco has released Programmable Addresses, smart contracts that run a preset action, such as swapping, bridging, depositing or splitting, automatically when tokens arrive at the address. Any sender can use the same permanent address from any supported chain without bridging or using a special app. The article says Eco deploys the contract on the first deposit only, and the most common use is cross-chain deposits that settle to a Solana wallet, such as a Phantom wallet. Programmable Addresses use Eco Routes for execution, with solvers competing to fulfill intents and automatic refunds if an intent expires unfulfilled.
