First successful bridge from Base Sepolia to @aztecnetwork Devnet is LIVE, powered by @Substance_Labs ⚡️ I’d drop the tx hash, but you wouldn't be able to see much because privacy actually works 👀

2/8 Our bridge enables confidential, trust-minimized cross-chain transactions between Aztec & Base (and all opstack chains that settle on Eth).💙 No liquidity pools. Just ERC-7683 intents, ZK-proofs and solvers who only get paid after proving execution. Full privacy & control.

Now imagine combining the power of ERC-7683 with privacy.... 🤯 someone might be working on this 👨🏻🔬👀
Less fragmentation, more liquidity ERC-7683 is the first cross-chain standard designed to solve liquidity fragmentation through a universal filler network Co-authored by Uniswap Labs and Across ⤵️

🚪 PRIVACY, MEET INTEROPERABILITY We’re building confidential cross-chain bridging for @aztecnetwork — enabling private, trust-minimized interactions across L2s. No new trust assumptions. Fully modular. Grateful to Aztec for backing work that’s important (and mysterious).
🚨1/2 Meet the winners of the Aztec <> L2s Cross-Chain Bridge RFP The challenge: to make privacy interoperable across L2s, so apps on Ethereum chains can integrate privacy without fragmenting users/liquidity Congrats @substance_labs, @wormhole & @nethermind, @trainprotocol!
