The new capability allows developers to assign a single address to a user or product running simultaneously on the corresponding Ethereum and Solana blockchains.
Eco, a stablecoin infrastructure platform backed by a16z Crypto, has introduced programmable addresses, a new feature designed to automate cross-chain routing for developers, enterprises and institutional users.
Typically, users manually transfer, exchange, or redistribute crypto assets after receiving funds.
This process is fragmented, time-consuming, and error-prone, especially in a multi-chain environment where liquidity, gas tokens, and wallet balances are spread across multiple networks. Each step often requires separate operations, additional fees, and exposure to the loss of money or the risk of partial execution.
With programmable addresses, Eco embeds execution logic directly into the address, allowing developers to automate cross-chain routing, treasury consolidation, payroll distribution, and other workflows without manual intervention.
“The industry has long viewed the withdrawal as the end of the transaction. However, in any functioning economy, this is only the beginning,” said Eco CEO Ryan Sachs. “By turning the address itself into an execution environment, we’re reducing the coordination costs associated with cross-chain interactions. It’s a transition from a world where reception happens with you to a world where it’s designed for you.”
The system runs on EVM and Solana compatible networks, eliminating gas tokens, liquidity distribution and reconciliation complexity. From Eco’s intent-based execution layer and resolution network, transactions are settled atomically with cryptographic guarantees.
Eco plans to expand support beyond its current network coverage and include tools such as ERC-7715, an automated wallet permissions standard that emerged from the development of Ethereum’s account abstraction.
Founded in 2018, Eco’s mission is to make digital assets a reality for everyday financial activities. In addition to a16z Crypto, the company is backed by Expa, Pantera Capital, Founders Fund and Coinbase Ventures, among others.
The company presents itself as an alternative to traditional financial products and seeks to integrate savings and payments into a single cryptographic wallet experience.
