CROSS-CHAIN GUIDE

How to bridge to Merlin

A real case from April 2026: a user bridged 0.130300 BTCB (~$9,512) from BNB and received 0.130286 WBTC on Merlin Chain via Symbiosis — 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 the exact flow:

  1. Picked the source. BNB as source, Merlin Chain as destination — the BTCB sat in a BNB wallet and the goal was access to Bitcoin L2 DeFi and BRC-20.

  2. Connected wallets. MetaMask on the BNB side, MetaMask on the Merlin Chain side. Symbiosis resolved the destination address automatically from the connected wallet — no manual paste required.

  3. Entered the amount. 0.130300 BTCB (~$9,512). The BNB wallet had enough balance to cover network gas.

  4. Reviewed the quote. Symbiosis displayed the exact WBTC amount on Merlin Chain, the flat Symbiosis fee in USD, and ETA. The quote was locked in before signing — 2% slippage tolerance protects against sudden price moves.

  5. Signed and confirmed. Signed the BNB transaction in MetaMask. WBTC arrived in MetaMask within ~33 sec. The transaction is fixed on-chain — verifiable on Symbiosis Explorer, BscScan, and Merlin explorer.

About the BNB to Merlin route

The Merlin corridor on Symbiosis routes BTCB, WRBTC and 100+ other tokens through the optimal mix of DEXes and bridge providers, with destination tokens delivered natively on Merlin Chain.

Hundreds of transactions have moved through this route in the last quarter, with top inbound sources from BNB, Rootstock, Bitcoin.

The corridor is non-custodial — funds remain in the user's wallet at every step, and the same widget supports the reverse direction (Merlin to multiple destinations). No sign-up, no KYC.

01

What is the best crypto bridge?

The best bridge depends on what you value, but Symbiosis offers concrete advantages for moving Bitcoin assets to Merlin: it's non-custodial, audited, and requires no KYC. Over the last 90 days it routed $109K across 57 transactions for 24 unique wallets, with a median delivery time of 36 seconds. A real demo transfer of 0.1303 BTCB (~$9,512) settled in just 33 seconds, so you get measurable speed rather than marketing claims.

02

Is Merlin still around?

Yes, Merlin Chain is active and seeing growth. Over the trailing 90 days the Symbiosis routing layer alone processed $109K in volume across 57 transactions, representing +134% quarter-over-quarter growth. Inbound activity comes mostly from BNB (66.8%) and Rootstock (28.8%), so bridging into Merlin remains live and functional.

03

What does Merlin chain do?

Merlin Chain is a Bitcoin Layer 2 where users bring Bitcoin-based assets into an EVM-style environment to swap, hold, and use them. For example, you can move BTCB from BNB and receive WBTC on Merlin, or bring WRBTC over from Rootstock. Through Symbiosis, the most common inbound assets are BTCB (66.8%), WRBTC (28.8%), and BTC (4.2%).

04

How do I swap tokens on Merlin?

To swap and bridge into Merlin using the Symbiosis widget, connect your wallet, choose your source chain and token (for instance BTCB on BNB), and set WBTC on Merlin as the destination. The routing engine returns a live quote — for example 0.01 BTCB converts to 0.010005 WBTC with a fee near $0.01. Confirm the transaction in your wallet and the assets arrive on Merlin, typically within a median of 36 seconds.

05

How do I track a Merlin bridge transaction?

After you confirm a bridge transaction in your wallet, you'll receive a transaction hash you can follow through the Symbiosis routing interface and on the relevant chain explorers. Most transfers complete fast — the median delivery is 36 seconds, though the 90th percentile can stretch to about 248 seconds during heavier routing. Keep your source-chain transaction hash handy as the reference point for tracking.

06

How do I bridge from Merlin to Bitcoin?

To move assets from Merlin back toward Bitcoin, open the Symbiosis widget, connect your wallet, and select Merlin as the source chain with your token (such as WBTC). Choose Bitcoin or a Bitcoin-linked asset as the destination, review the live quote and fee, then confirm. Settlement is generally quick, with a 90-day median delivery of 36 seconds across the routing layer.

07

How do I bridge from BNB Chain to Merlin?

Open the widget above and set Source to BNB Chain, Destination to Merlin. 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 Rootstock to Merlin?

Open the widget above and set Source to Rootstock, Destination to Merlin. 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.
