Connext's cross-chain bridging protocol options announced a brand new token commonplace to cut back losses from bridge hacks. In response to an announcement on July 24, the brand new "xERC-20" commonplace will permit token issuers to keep up a listing of official bridges and management what number of tokens every one can mint.
The announcement states that alongside Connext, DeFi platform Alchemix Finance may also implement xERC-20 tokens.
At present, Connext broadcasts help for the xERC20 commonplace and onboarding initiatives to securely convey its tokens onto any chain.

The brand new token commonplace was initially offered on July seventh as Ethereum Enchancment Proposal (EIP) 7281. It was co-authored by Connext founder Arjun Bhuptani. On the time, Bhuptani stated that performing on the precept, "Token issuers are those who get rectified when bridges are hacked," would assist reduce losses from bridge hacks.
As an alternative of every bridge on every community issuing its personal model of a token, the brand new commonplace would permit bridges to mint "official" or "canonical" variations of every token. Nonetheless, they'll solely do that with the permission of the token issuer, and that permission could be enforced via sensible contracts. In response to the proposal, token issuers may additionally restrict the variety of cash a given bridge may mint.
Underneath EIP-7281, bridges may nonetheless mint their very own variations of tokens, however such by-product cash wouldn't be thought of "canonical" variations. In consequence, shoppers would ultimately reject unofficial variations of cash. In Bhuptani's view, this might lead to a safer DeFi area because the accountability for avoiding bridge hacks could be positioned squarely on the shoulders of every token issuer, which might assist stop end-users from struggling losses.
To turn into an official a part of the Ethereum ecosystem, an EIP should be accepted by the EIP publishers, a course of that may take months. The July 24 announcement stated the usual will now be applied in Connext and Alchemix forward of its official approval, so end-users can depend on it instantly.

Within the announcement, Connext acknowledged that the token commonplace shall be "upward suitable" with the official model ought to it will definitely be accepted by the EIP publishers. Bhuptani argued that the brand new implementation will stop bridges with poor safety or overly centralization from being taken severely, 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 establishing a liquidity monopoly or making an attempt to seize market share by locking in token issuers (or total chains in some circumstances), bridges at the moment are pressured to continuously concentrate on their safety and high quality of service to keep away from being delisted.”
The subject of bridge safety has turn into a sizzling matter within the crypto group. These issues grew on July 7 when over $100 million was mysteriously drained from the multichain bridging protocol. The Multichain crew initially solely described the withdrawals as "irregular", however later clarified that an unknown individual had accessed their CEO's cloud storage system to withdraw the funds with out customers' consent.
