Fantom was a top 20 blockchain. It had a problem. So they did something almost no project has ever done — they scrapped everything and rebuilt from scratch.
Meet Sonic. And the old chain shuts down permanently on June 30, 2026.
✦ Sonic processes more than 10,000 transactions per second with each transaction completing in under 1 second — using parallel execution that allows multiple transactions to process simultaneously instead of one by one (KuCoin)
✦ Developers on Sonic earn up to 90% of all network fees generated by their applications through the FeeM program — making it one of the most developer-friendly blockchains ever built (DEXTools)
✦ Any smart contract written for Ethereum, Arbitrum, Base, or any EVM chain can be redeployed on Sonic with minimal changes — giving it instant access to the entire Ethereum developer ecosystem (DEXTools)
✦ Andre Cronje — the legendary DeFi developer who built Yearn Finance and protocols that processed hundreds of billions in volume — is the technical lead for Sonic. His new DEX on Sonic was valued at $1 billion and raised $25.5 million (Traders Union)
✦ The legacy Fantom Opera network officially shuts down on June 30, 2026 — users with unmigrated FTM tokens must complete their 1:1 swap to S before this deadline or risk losing access (Bitcoin Foundation)
A complete rebuild. The creator of Yearn Finance leading development. 10,000 TPS. Developers earning 90% of fees.
Most blockchains evolve slowly. Sonic burned the old version down and started fresh.
