Ronin + Chainlink CCIP: The Future of the Cross-Chain Bridge

Ronin has begun migrating its bridge infrastructure to Chainlink CCIP (Cross-Chain Interoperability Protocol), a protocol approved by the network’s validators in 2023 as the new standard for cross-chain interoperability. This decision aims to improve the ecosystem’s security and scalability by fully replacing the legacy Ronin Bridge.

Key Migration Dates

The transition to CCIP will occur in three main stages:

• April 9: The legacy bridge remains active, while most tokens are already bridgeable through CCIP.
• April 21: The legacy bridge is officially deprecated. From this point onward, only CCIP will be available.
• April 24–25: Any remaining tokens on the legacy bridge will be migrated to CCIP. After this, CCIP will assume 100% of the legacy bridge’s functions.

What Is the Ronin Bridge with CCIP?

The Ronin Bridge with CCIP enables secure transfers between Ronin and compatible chains, using Chainlink infrastructure. This integration enhances fund security and improves compatibility with assets and applications from other networks.

No downtime is expected during the migration process, though minor disruptions may occur. The CCIP bridge will remain fully operational throughout the transition.

Supported and Unsupported Tokens

Currently, the CCIP bridge supports the transfer of the following assets:

• Supported tokens: WETH, USDC, AXS, PIXEL, and more.
• Not yet supported: WBTC, LUA, LUAUSD.

Additional tokens may be added progressively in the future.

Recommendations for Developers and Exchanges

Ronin recommends that developers and centralized platforms:

• Grant dual minter rights to CCIP to ensure proper functionality and support a smooth ecosystem transition.
• Review current integrations and make any necessary adjustments as CCIP becomes the exclusive bridge.

GO TO THE BRIDGE

By adopting Chainlink CCIP as its only bridge infrastructure, Ronin aims to strengthen asset transfer security and enable new expansion opportunities into other blockchain ecosystems. The migration will be completed by April 25, marking the final deprecation of the legacy bridge and the beginning of a new phase for the network.
