The Connext cross-chain bridging protocol has introduced a brand new token commonplace to cut back losses from bridge hacks. In line with a July 24 announcement, the brand new “xERC-20” commonplace permits token issuers to take care of an inventory of official bridges and management what number of tokens may be minted by every.
Along with Connext, decentralized finance (DeFi) platform Alchemix Finance will implement xERC-20 tokens, the announcement said.

In the present day, Connext is asserting assist of the xERC20 commonplace and onboarding tasks into safely bringing their tokens to each chain.
As our flagship person, we have been working with @AlchemixFi to convey $alUSD, $alETH, and $ALCX to @arbitrum and @optimismFND. https://t.co/S2tBLpuuqe

The brand new token commonplace was initially put forth on July 7 as Ethereum Enchancment Proposal (EIP) 7281. It was co-authored by Connext’s founder Arjun Bhuptani. On the time, Bhuptani stated it could assist to reduce losses from bridge hacks by performing on the precept that “Token issuers are those who get rekt when bridges get hacked.”
As an alternative of every bridge issuing its personal model of a token on each community, the brand new commonplace would permit bridges to mint “official” or “canonical” variations of every token. Nonetheless, they will solely do that with the permission of the token issuer, and this permission can be enforced by good contracts. Token issuers would additionally have the ability to restrict the variety of cash {that a} specific bridge may mint, the proposal said.
Below EIP-7281, bridges may nonetheless mint their very own variations of tokens, however such by-product cash wouldn’t be thought of “canonical” variations. Because of this, customers would ultimately come to reject unofficial variations of cash. In Bhuptani’s view, this is able to result in a safer DeFi house as a result of it could put the duty for avoiding bridge hacks squarely on the shoulders of every token issuer, which might assist to stop finish customers from struggling losses.
To turn into an official a part of the Ethereum ecosystem, an EIP needs to be authorised by EIP editors, a course of that may take months. The July 24 announcement stated the usual will now be carried out in Connext and Alchemix forward of its official approval, permitting finish customers to depend on it instantly.

Within the announcement, Connext said that the token commonplace might be “ahead appropriate” with the official model ought to it will definitely be authorised by the EIP editors. Bhuptani argued that the brand new implementation will stop bridges with dangerous safety or extreme centralization from being taken severely, stating:
“This strategy […] encourages open competitors and innovation as token issuers now have the flexibleness [to] granularly replace their preferences for supported bridges over time. As an alternative of prioritizing constructing a monopoly on liquidity, or making an attempt to nook market share by locking-in token issuers (or in some circumstances total chains), bridges at the moment are pressured to have an ongoing give attention to their safety and high quality of service, lest they be delisted.”
The problem of bridge safety has turn into a sizzling matter within the crypto group. These issues had been amplified on July 7, when over $100 million was mysteriously withdrawn from the Multichain bridging protocol. The Multichain workforce at first solely referred to the withdrawals as “irregular” however later clarified that an unknown particular person had accessed the CEO’s cloud storage system to withdraw the funds with out customers’ consent.
