CROSS-CHAIN GUIDE

How to bridge to Sonic

Example quote from 25 September 2026: sending 3,000 USDC (~$3,000) from Ethereum returns about 74,095 S on Sonic via Symbiosis, estimated ~36 sec — no wrapped tokens beyond the standard route, fully non-custodial. Symbiosis works as a liquidity meta-aggregator, comparing routes across multiple DEXes and bridge providers and picking the best one by price, fee, and speed automatically. This is one of the most popular flows on this corridor; the same widget supports any source chain and token combination. Here's how the flow works:

  1. Pick the source. Set Ethereum as source and Sonic as destination — the USDC sits in an Ethereum wallet, and the goal is access to Sonic DeFi (Beethoven X, Equalizer).

  2. Connect wallets. MetaMask on the Ethereum side, MetaMask on the Sonic side. Symbiosis reads the destination address automatically from the connected wallet — no manual paste required.

  3. Enter the amount. 3,000 USDC (~$3,000) in this example. Keep enough ETH in the wallet to cover network gas.

  4. Review the quote. Symbiosis displays the exact S amount on Sonic (about 74,095 S in this example), the flat Symbiosis fee in USD, and ETA (~36 sec). The quote is locked in before signing — 2% slippage tolerance protects against sudden price moves.

  5. Sign and confirm. Sign the Ethereum transaction in MetaMask. S arrives in MetaMask once the route completes — track the transfer on Symbiosis Explorer.

About bridging to Sonic

  • Why this route. Sonic's DeFi runs on S: holders stake it with Beets to get stS, lend on Aave and Silo, and trade on Shadow.

  • What you receive. S, the native token of Sonic (chain ID 146), arrives ready to pay fees. The example spends USDC on Ethereum and requires one signature.

  • Watch out for. Sonic succeeded Fantom, but Fantom Opera (chain ID 250) is a separate network and FTM there is not S. FTM converts to S one way at 1:1 only through the Sonic upgrade portal, so make sure the wallet is set to Sonic.

  • Speed. Across all routes into Sonic, median delivery 18 seconds; 90th percentile 79 seconds, over the 90 days to 25 September 2026.

WHY SYMBIOSIS

Secure by design. Proven at scale

Audited in the open

No KYC, no custody, no intermediaries. Audited by Decurity, Zokyo, SlowMist, and Omniscia — 13 public audit reports across 11 protocol modules (Core, MetaRouter v3, Pool, TON Bridge v1+v2, Relayers Network, Staking, Frontend). All reports open-source on GitHub. 4+ years live on mainnet (since March 2022) with zero major security incidents. Active bug bounty program.

Two-layer staking security

Cross-chain transactions routed via Octopools AMM (scans liquidity across DEXs and chains for minimal slippage), then signed by an MPC group via Threshold Signature Scheme (TSS) — no single party can move user funds. Two security layers: Symbiosis PoS Staking (SIS-collateralised relayer nodes) + Symbiotic restaking (additional slash-able collateral). 2/3 stake quorum for epoch changes.

$8B+ across 54 chains

$8B+ total volume bridged across 5M+ transactions from 800K+ unique wallets. Supports 54 networks — more than any other cross-chain bridge (Across 35+, deBridge 30+, Allbridge 20). EVM + non-EVM in one route — Ethereum, Solana, BNB Chain, TON, Tron, Bitcoin, Arbitrum, Polygon, and 46 more. Per-transaction range: $10 to $140,000 — handles retail swaps and whale trades on the same route.

01

What is the safest crypto bridge?

Safety comes down to whether a bridge is non-custodial, audited, and lets you transact without handing over identity — Symbiosis is all three, with no-KYC routing that never takes custody of your funds. On the Sonic routing layer specifically, transfers over the last 90 days settled with a median delivery of 18 seconds as of September 2026, so the speed and reliability are observable on-chain rather than promised.

02

How do I bridge from Sonic to Ethereum?

Open the Symbiosis widget, set Sonic as your source chain and Ethereum as your destination, then pick the token you want to move and connect your wallet. Confirm the transaction and the routing engine handles the rest. Most deliveries land around the 68-second median, with the 90th percentile at 158 seconds as of September 2026.

03

How do I swap tokens on Sonic?

To swap on Sonic, connect your wallet in the Symbiosis widget and choose your input and output tokens; the routing engine returns a live quote before you confirm. For reference, on 28 September 2026, 250 USDC from Ethereum delivered 6,477 S with a $2.82 fee (full cost in the Symbiosis app plus gas), and 2,500 USDC delivered 64,847 S with a $17.45 fee; the exchange rate is already reflected in the amount you receive. Median delivery on this route is 23 seconds as of September 2026.

04

How do I track a Sonic bridge transaction?

After you confirm a transfer, the widget shows live status as the Symbiosis routing engine processes and delivers your funds to Sonic. Typical settlement runs to an 18-second median, with slower cases reaching about 79 seconds at the 90th percentile as of September 2026. You can also verify the final delivery directly on Sonic using your wallet and the destination transaction hash.

05

How do I bridge from Sonic to Solana?

A direct Sonic to Solana route is not available on Symbiosis: a live quote request for it on 25 September 2026 returned no route. From Sonic you can bridge to networks such as Ethereum, Base, Arbitrum One, Optimism and Polygon, so to reach Solana you can bridge to Ethereum first and then from Ethereum to Solana.

06

Is there an official Sonic bridge?

Yes. Sonic Labs runs the Sonic Gateway, Sonic's native bridge between Ethereum and Sonic. Symbiosis is an independent cross-chain bridge: the widget above connects directly to the Symbiosis routing contracts on each network. There is no separate app or sign-up — the same widget works for Sonic and other chains, all from your wallet.

07

How do I bridge from Base to Sonic?

Open the widget above and set Source to Base, Destination to Sonic. Pick your token on each side — the widget pulls a live quote from the Symbiosis routing engine and shows the receive amount and fee before you sign. No native gas required on the destination.

08

How do I bridge from Arbitrum to Sonic?

Open the widget above and set Source to Arbitrum, Destination to Sonic. Pick your token on each side — the widget pulls a live quote from the Symbiosis routing engine and shows the receive amount and fee before you sign. No native gas required on the destination.
