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

At present, Connext is saying help of the xERC20 customary and onboarding initiatives into safely bringing their tokens to each chain.
As our flagship person, we have been working with @AlchemixFi to deliver $alUSD, $alETH, and $ALCX to @arbitrum and @optimismFND. https://t.co/S2tBLpuuqe

The brand new token customary 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 mentioned it will assist to reduce losses from bridge hacks by appearing 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 customary 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 via good contracts. Token issuers would additionally be capable to restrict the variety of cash {that a} explicit bridge might mint, the proposal acknowledged.
Below EIP-7281, bridges might nonetheless mint their very own variations of tokens, however such spinoff cash wouldn’t be thought of “canonical” variations. Consequently, shoppers would ultimately come to reject unofficial variations of cash. In Bhuptani’s view, this could result in a safer DeFi area as a result of it will 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 must be permitted by EIP editors, a course of that may take months. The July 24 announcement mentioned 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 acknowledged that the token customary will likely be “ahead suitable” with the official model ought to it will definitely be permitted by the EIP editors. Bhuptani argued that the brand new implementation will forestall bridges with dangerous safety or extreme centralization from being taken significantly, stating:
“This method […] encourages open competitors and innovation as token issuers now have the pliability [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 instances whole chains), bridges are actually compelled to have an ongoing deal with their safety and high quality of service, lest they be delisted.”
The problem of bridge safety has turn into a scorching subject within the crypto group. These considerations had been amplified on July 7, when over $100 million was mysteriously withdrawn from the Multichain bridging protocol. The Multichain staff 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.
