Leviathan Atlas now tracking Sonic, a layer-2 network featuring sub-second finality and native USSD stablecoin.
DeFi & Yields ·
Leviathan Atlas has begun tracking Sonic, an EVM-compatible layer-1 blockchain that succeeds Fantom Opera and introduces a native token called S alongside a USD stablecoin, USSD. The network is built on a DAG-based consensus protocol designed to deliver sub-second finality and support up to 10,000 transactions per second, positioning itself as a high-throughput alternative to legacy infrastructure.
Sonic emerged as a deliberate architectural reset rather than an upgrade to Fantom Opera, prompted by performance and design constraints in the original chain. The transition involved building a separate mainnet with a fresh consensus protocol, new token, and migration pathway for existing users and applications. As an EVM-compatible layer-1, Sonic allows Ethereum and Fantom projects to redeploy with minimal friction and integrates with standard Web3 tooling including wallets and block explorers. The network pairs low-cost transactions with a value-capture model that extends beyond gas fees to include revenue from native financial infrastructure.
Notable recent developments include leadership changes at Sonic Labs—with Andre Cronje and two board members departing while the S token declined significantly from its peak—and the introduction of a post-quantum roadmap. An October 15 deadline for airdrop claims resulted in 32.7 million unclaimed S tokens facing permanent burn. The precise mechanics of USSD issuance, reserve backing, and the full scope of vertical DeFi integration remain subjects of ongoing technical documentation Leviathan Atlas.
