Fast Finality Layer for Soneium

PreviousUser Delegation GuideNextOperator Guide

Last updated 5 days ago

Fast Finality Layer for is an Autonomous Verifiable Service (AVS) built by AltLayer and powered by EigenLayer’s restaking framework in collaboration with . It delivers sub-10 second finality for transactions on Soneium — an OP Stack-based L2 — by enabling decentralized validation of rollup state transitions. Backed by restaked ETH and ASTR on EigenLayer, this fast finality layer offers high-throughput apps near real-time confirmation, enhanced crypto-economic security, and seamless integration with Soneium's developer stack. Soneium, an Ethereum layer-2 developed by Sony Block Solutions Labs, is a versatile general-purpose blockchain platform that aims to evoke emotion, empower creativity, and realize the open internet that transcends boundaries.
