The new capability allows developers to assign a single address to a user or product that functions across Ethereum-compatible chains and Solana simultaneously.
Eco, a stablecoin infrastructure platform backed by a16z Crypto, has introduced Programmable Addresses, a new feature designed to automate cross-chain fund routing for developers, enterprises, and institutional users.
Traditionally, users manually bridge, swap, or redistribute crypto assets after receiving funds.
This process is fragmented, time-consuming, and prone to error, especially in a multi-chain environment where liquidity, gas tokens, and wallet balances are spread across different networks. Each step often requires separate transactions, additional fees, and exposure to bridge failures or partial execution risk.
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 receipt of funds as the conclusion of a transaction. However, in any functional economy, it is just the beginning,” said Eco CEO Ryan Saxe. “By making the address itself an execution environment, we are reducing the coordination overhead associated with cross-chain interactions. This represents a shift from a world where receiving happens to you, to one where it is designed for you.”
The system operates across EVM-compatible networks and Solana, abstracting away gas tokens, liquidity fragmentation, and reconciliation complexity. Powered by Eco’s intent-based execution layer and solver network, transactions settle atomically with cryptographic guarantees.
Eco plans to extend support beyond its current network coverage and integrate tools like ERC-7715, a standard for automated wallet permissions that emerged from Ethereum’s account abstraction development.
Founded in 2018, Eco’s goal is to make digital assets practical for daily financial activity. In addition to a16z Crypto, the firm is backed by Expa, Pantera Capital, Founders Fund, and Coinbase Ventures, among others.
The company positions itself as an alternative to traditional financial products, seeking to merge savings and payments into a single crypto-based wallet experience.
