Cardano

Cardano has launched its algorithmic stablecoin, Djed (DJED), on its mainnet after a successful security audit.

The stablecoin, backed by Cardano’s native ADA token, is pegged to the US dollar and uses the Shen (SHEN) token as its reserve coin.

Unveiled in November last year, the announcement was met with widespread online debate over the place of algorithmic stablecoins in the future of blockchain, given the collapse of TerraUSD (UST) months prior.

Visa will ‘actively contribute’ to web3 development

Visa refuses to become a dinosaur and will “actively contribute” to developing the web3 and crypto ecosystem.

Aside from maximalists, few experts believe that crypto poses an existential threat to fiat currencies. Legacy payment processors like Visa and Mastercard have increasingly been joining the web2-era disruptors like PayPal and Square in supporting the web3 and crypto ecosystem.

Greater public adoption of “crypto” will likely come through CBDCs (Central...

Half of all DeFi exploits come from cross-chain bridge attacks

Crypto Hacker

A half of all DeFi exploits occur on cross-chain bridges and a staggering £2.2 billion has been stolen from them by hackers in the past two years.

The latest figures come from a new report by crypto data aggregator Token Terminal and stand out as enormous in comparison to other DeFi security breaches.

In the same period, hackers netted only £635 million from DeFi lending hacks and a comparatively meagre £320 million from decentralised exchange...
