An Ethereum Enchancment Proposal (EIP) made on July 7 seeks to standardize how tokens are bridged between networks. The “Sovereign Bridged Token” commonplace, or EIP-7281, permits token issuers to create canonical bridges throughout a number of networks.
The proposal was co-authored by Arjun Bhuptani, founding father of the Connext bridging protocol. In a July 7 social media submit, Bhuptani claimed the protocol would assist forestall points just like the July 6 Multichain incident, which some specialists have described as a hack.
At present’s @MultichainOrg hack is a tragic reminder of the systemic dangers tokens face from bridges.
We imagine these dangers stem from a single underlying downside:
✨Token Sovereignty✨
We’re proposing ERC-7281 (aka xERC20) – an open commonplace to repair this.https://t.co/k9Vyd55Eb5

In response to the proposal’s dialogue web page, it permits token issuers to designate a listing of canonical bridges. Solely bridges added to this checklist may mint an official model of the issuer’s token. Issuers may restrict the variety of tokens a bridge is allowed to mint. These parameters might be modified at nearly any time by the issuer.
In Bhuptani’s view, this proposal will make sure that “possession of tokens is shifted away from bridges (canonical or third occasion) into the fingers of token issuers themselves” and can restrict losses if a bridge’s safety comes into query:
“Within the occasion of a hack or vulnerability for a given bridge (e.g. at the moment’s Multichain hack), issuer threat is capped to the speed restrict of that bridge and issuers can seamlessly delist a bridge with no need to undergo a painful and time-intensive migration course of with customers.”

Bhuptani mentioned the proposal would additionally assist forestall person expertise issues in decentralized finance, as all bridges will challenge the identical official token. Over time, this can eradicate the necessity for a number of variations of the identical token, he claimed.
Stablecoin issuer Circle has already created the Cross-Chain Switch Protocol (CCTP) to checklist official bridges for its token, USD Coin (USDC). EIP-7281 intends to implement the essential idea behind CCTP but in addition tries to make this answer apply “extra broadly to all tokens,” in accordance with the proposal’s notes.
Each Circle and Tether have blacklisted among the addresses used within the Multichain incident, stopping $65 million value of USDC and Tether (USDT) from being moved out of those addresses.
