Context

opBNB is a Layer 2 blockchain built on the bedrock version of the Optimism OP Stack. It serves as a scaling solution for the BNB Smart Chain, providing higher throughput and lower transaction costs without compromising security.

As part of the OP Stack architecture, opBNB offers full EVM compatibility, allowing seamless deployment of Ethereum-native smart contracts.

The opBNB mainnet was launched in September 2023.

Proposal

Enable support for the opBNB blockchain network within the Symbiosis protocol. The integration includes the following steps:

• Deploying and tuning Symbiosis contracts on opBNB to ensure smooth operation.
• Adding token for opBNB in the Symbiosis AMM DEX on the host chain: WETH
• Leveraging existing DEXs on opBNB to enable on-chain routing.
• Activating the Symbiosis Relayers Network to work with the new blockchain.

Key Points

• opBNB maintains high user and transaction volume, indicating strong adoption in mass-market dApps and reinforcing the need for cross-chain liquidity access.
• Although opBNB has native bridges to BSC, users still require multichain routing — which Symbiosis enables across diverse ecosystems.
• The EVM compatibility ensures straightforward integration into Symbiosis, enabling immediate cross-chain swaps and expanding token liquidity options.
