CROSS-CHAIN GUIDE

How to bridge to Rootstock

Example quote from 25 September 2026: sending 3,000 USDC (~$3,000) from Ethereum returns about 0.0354 RBTC on Rootstock via Symbiosis, estimated ~61 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:

Pick the source. Set Ethereum as source and Rootstock as destination — the USDC sits in an Ethereum wallet, and the goal is access to Bitcoin DeFi (Sovryn, Money on Chain).
Connect wallets. MetaMask on the Ethereum side, MetaMask on the Rootstock side. Symbiosis reads the destination address automatically from the connected wallet — no manual paste required.
Enter the amount. 3,000 USDC (~$3,000) in this example. Keep enough ETH in the wallet to cover network gas.
Review the quote. Symbiosis displays the exact RBTC amount on Rootstock (about 0.0354 RBTC in this example), the flat Symbiosis fee in USD, and ETA (~61 sec). The quote is locked in before signing — 2% slippage tolerance protects against sudden price moves.
Sign and confirm. Sign the Ethereum transaction in MetaMask. RBTC arrives in MetaMask once the route completes — track the transfer on Symbiosis Explorer.

About bridging to Rootstock

Why this route. Rootstock is an EVM sidechain merge-mined with Bitcoin. People bridge in for bitcoin-based DeFi: lending and margin trading on Sovryn, or minting dollar stablecoins such as USDRIF on RIF On Chain.
What you receive. RBTC, Rootstock's native coin, pegged 1:1 to BTC through the PowPeg and used for all fees there, so you can transact right away. You sign one transaction on Ethereum, starting from USDC.
Watch out for. Rootstock (chain ID 30) adds its chain ID to the address checksum (EIP-1191), so capital letters in your address may differ from Ethereum. Wallets on Rootstock's own derivation path (m/44'/137') show another account; check which one is connected.
Speed. Across all routes into Rootstock, median delivery 2 minutes; 90th percentile 17 minutes, over the 90 days to 25 September 2026.

What is Rootstock (RSK) in crypto?

Rootstock, also known as RSK, is a Bitcoin sidechain that brings smart contract functionality to the Bitcoin ecosystem. Its native asset is RBTC, which is pegged to BTC, and it lets you move value from chains like Ethereum and Arbitrum One into a Bitcoin-secured environment. With the Symbiosis bridge you can route assets such as USDC and WBTC into Rootstock without giving up custody of your funds.

How does the Rootstock bridge work on Symbiosis?

Connect your wallet, choose your source chain and token (for example USDC on Ethereum), then select Rootstock as the destination and confirm the transaction. The Symbiosis routing engine handles the cross-chain swap automatically and delivers your assets, with a median delivery time of about 2 minutes as of September 2026. The 90th percentile can reach about 17 minutes during busier periods.

How much does it cost to bridge to Rootstock?

On 28 September 2026, bridging 1,000 USDC from Ethereum to Rootstock delivered 0.01195 RBTC with an $8.07 fee (full cost in the Symbiosis app plus gas), and 10,000 USDC delivered 0.1196 RBTC with a $63.53 fee. The exchange rate is already reflected in the amount you receive, and the widget shows the exact fee for your amount before you sign.

What is the best wallet for RBTC on Rootstock?

Any wallet that supports the Rootstock chain and its EVM-compatible network can hold RBTC. When bridging through Symbiosis, simply connect a compatible wallet to approve the source-chain transaction and receive your assets on Rootstock. Symbiosis is non-custodial, so your keys and funds remain entirely under your control throughout the transfer.

How do I buy or get Rootstock assets?

Rather than buying directly, you can bridge existing assets into Rootstock using Symbiosis. The most common route is USDC from Ethereum, but you can also bring assets from Arbitrum One, Merlin, or BNB Chain.

Is the Symbiosis Rootstock bridge safe?

Symbiosis is non-custodial and audited, and it requires no KYC, so you never hand over personal data or control of your funds. Transfers complete with a median time of about 2 minutes as of September 2026.

Which chains can I bridge from to reach Rootstock?

Symbiosis routes inbound transfers to Rootstock from several networks, such as Ethereum and Arbitrum One. Other supported sources include Merlin and BNB Chain. You select your origin chain directly in the bridge widget before confirming.
