Wormhole goes multichain with native token transfers
Cross-chain messaging platform Wormhole has launched native token transfers (NTT) as a approach to protect token traits and tackle liquidity fragmentation throughout totally different blockchains.
Sending tokens throughout totally different blockchain platforms right this moment normally requires a token bridge. These bridges usually use both the “lock and mint” or “burn and mint” method when enabling these transfers.
This course of entails customers locking up the native asset into a sensible contract on one chain after which swapping it for an artificial model of that asset earlier than it’s transferred to a distinct chain. As soon as on one other chain, customers will once more have to undergo the method of switching the artificial asset to a local token.

Nevertheless, in response to Nikhil Suri, product lead on the Wormhole Basis, as a result of interoperability protocols deploy wrapped belongings on behalf of a challenge, these belongings are non-fungible between the totally different interoperability protocols, resulting in liquidity fragmentation, which may end up in a nasty UX and sub-optimal markets.
“One other downside of wrapped belongings is that they’re owned by interoperability protocol contracts, in order that they conform to a hard and fast token implementation. This limits flexibility for protocols trying to take their very own tokens cross-chain since their tokens gained’t behave persistently on all chains and won’t retain any superior performance,” Suri instructed Blockworks.
One other method of transferring belongings throughout totally different blockchains right this moment may very well be by having a unified liquidity pool shared by a number of totally different chains. Nevertheless, this kind of bridging can’t assure instantaneous finality because the totally different chains should guarantee sufficient liquidity within the swimming pools to meet all requests.

Not like present strategies for transferring tokens throughout chains, NTT entails protocols natively deploying their canonical token to a number of blockchains and utilizing interoperability layers to facilitate the transfers between these canonical deployments.
Which means when new tokens are transferred utilizing the “burn and mint” or “lock and mint” methodology with multichain’s NTT, as a substitute of swapping the native token for an artificial asset earlier than sending it to a different chain after which switching it again once more as soon as it arrives on the vacation spot chain, customers will be capable of instantly switch native tokens from one chain to a different.
“Compared to wrapped belongings, native token transfers make sure that tasks preserve possession, upgradeability and customizability over their tokens on numerous blockchains. Which means tokens can preserve their distinctive traits irrespective of which chain they’re transferred to,” Suri mentioned. “Native token transfers additionally keep away from liquidity fragmentation by transferring worth as a substitute of double counting it.”
Because of this, Suri believes that native tokens are greater than only a technical evolution, but in addition a step towards realizing the potential of blockchain expertise.
“They will function long-term options which are in a position to evolve alongside the protocols that leverage them,” he mentioned. “As we transfer ahead, interoperability will proceed to play an essential position in shaping a sturdy and user-centric DeFi house and supply tasks with the sovereignty to outline what works greatest for them.”
