20 Subchains Covered: How #lagrange Became the 'Universal Interface' for Multi-chain Verification

How difficult is it for developers in the multi-chain era? To adjust cross-chain data, they need to integrate N APIs, and each verification takes half a day. @Lagrange Official 's Lagrange Prover Hub aims to be the 'multi-chain translator'—by August 2025, it has supported 20 sub-networks including Arbitrum and Polygon, with over 22,000 ETH staked, making cross-chain verification a 'matter of a sentence'.

Its secret lies in the 'Unified Verification Layer': regardless of the data from any chain, it is first preprocessed through the Verifiable Database, with indexing efficiency reaching 180,000 records per second after upgrades in July. Developers can query directly using SQL, without needing to learn the interface rules of each chain. A cross-chain DApp team mentioned that previously, verifying data from 5 chains required writing 200 lines of code, but now with Lagrange's ZK Coprocessor, it can be done in just 30 lines, reducing costs by 60%.

@Lagrange Official has also maximized security: as an AVS on EigenLayer, it directly benefits from Ethereum's re-staking security, and there have been no data security issues across the 20 sub-chains. Among the 110 operators, there are both large institutions like OKX and distributed nodes like P2P.org, ensuring both decentralization and stability. With 85 million transactions and 320 million API calls, it proves that the multi-chain world urgently needs this 'universal interface'.

The token $LA serves as a 'stake certificate': staking LA allows it to act as a cross-chain verification node, and developers pay with LA for the interface. The more subchains that are supported, the more valuable LA becomes. #lagrange has made a bold move: rather than having developers piece together the 'on-chain puzzle', it prefers to be the 'puzzle base'. If it expands to a few more chains, it is likely to become the 'must-install plugin' for the multi-chain ecosystem.
